Apparatus and method for a split type water extractor and water dispenser

A split type potable water extractor from ambient air and water dispenser is invented, comprising separate water generating block located outside a water use area and water dispensing block located inside a water use area. The water generator block cycles refrigerant through a condenser and an evaporator to create condensation by heat exchange with ambient air circulated by an intake airflow system. The condensate water is collected and purified in a cascade of bactericidal loop to remove impurities. The purified water is pumped to a dispensing apparatus that can be installed in the home or other area of water use separate from the water generating block. If any one of the functional parts or units of water generator is disabled the water generator immediately stops operating to deliver water to the tank of the dispensing apparatus.

FIELD OF THE INVENTION

This invention relates to a technology for extracting water from ambient air for human use.

BACKGROUND OF THE INVENTION

In many developing and even developed countries there is a dire need for potable water. Moreover, in many areas water is taken from non-treated sources that may contain significant amounts of viruses, bacteria, heavy metals and other dangerous contaminants to human health. The Natural Resources Defense Council estimates that even in the U.S. hundreds of people die each year from water-borne diseases. Given the need for potable water, it is becoming urgent to develop highly efficient, simple and reliable technologies for generating pure water from ambient air.

In the prior art, water generators have not proven to be efficient in satisfying the need for potable water. Such water generators have suffered from a number of disadvantages, which make the energy and economic costs of producing potable water impracticable. One disadvantage is that such water generators are generally not designed to be of the split type, with the water generating unit separated from the water dispensing unit to optimize efficiency. Another disadvantage of prior art water generators is that they are equipped with evaporators having defrosting facilities based on hot refrigerant gas flow bypassing reverse cycle. The described kind of deicer system requires complication of the generator structure, and at the same time consumes more energy without producing water during all the process of reverse cycle defrosting. And yet another disadvantage of other water generators is that they are not energy efficient because they use compressors that operate to maintain a cold set-point temperature within the water reservoir that requires the operation of the compressors even when the generators do not actively produce water. Consequently, existing water generators have been demonstrated to consume a lot of energy while not allowing permanent and reliable water production.

Accordingly, there is a need for an efficient system and method of extracting potable water from ambient air according to this invention, wherein outside air is cooled by a refrigeration system in consequence of which the vapor contained in air is condensed and transformed into water which is collected in a closed tank and further, after having been purified in a cascade of bactericidal loop, is pumped into a water dispensing block, which can be installed in the home or other areas of water use. In present invention the disadvantages of the prior art are eliminated, while improving the reliability and energy efficiency, reducing initial cost per unit of water productivity, optimizing process parameters including air flow through the evaporator and condenser, and maintaining the quality of recovered water, etc.

SUMMARY OF THE INVENTION

This invention is for a split type potable water extractor from ambient air and water dispenser for use in remote and waterless areas consisting of a water generating block and a water dispensing block. The generating block is located outside the water use area and has direct contact with outside air and the water dispensing block is located inside the water using area. The extractor is designed to be split type, that is to say composed of separately standing water generating and water dispensing units (blocks).

The potable water generator block functions to extract water from the outside atmosphere air by cooling. The invented water generator block is a stationary device that does not need to be moved or shifted and can be hanged on the outside surface of wall or stand on ground near the house without occupying inside space.

The split type structure is directed to avoid of the problem of creating dry microclimatic conditions in the dwelling place that results from long period use of inside air as a water source since the inside air becomes extremely dried and, therefore, unusable as a sustained water source. For these reasons the developed apparatus uses only fresh outside air as water containing medium, which at the same time has the advantage of being much cleaner than the inside air.

The apparatus is designed for operating long periods without freezing problems because the intake air is not cooled up to the dew point temperature. Instead, in this extractor the surface temperature of the evaporator is kept below the dew point temperature of air by cold refrigerant.

In consequence of heat exchange the air is cooled up to temperatures far higher than the dew point, but enough for condensing the water vapor on the surface of evaporator. The water from the surface of the evaporator drips into a receptor pan and then runs into a closed tank system equipped with a level control device which is connected to the generator's switching off/on panel.

For producing high-quality, purified water the heat transfer surface of the evaporator is coated by special food type inert painting and all interior and exterior of the housing are made of medical-grade 314L stainless steel. With the use of a pump, the water repeatedly circulates through a cascade of water filters. The preferred filters are high rate and small-pore filter/adsorption media such as a porous-carbon block in a NSF-53 certified filter, which filters from the water organic compounds, insects, and any other contaminants. Such purification is done in accordance with ASHRAE and U.S. federal standards.

The purified water from the cascade of bactericidal loops goes through a solenoid valve, which is controlled by a timer. The water is then pumped into a water storing tank of a dispensing block, which is installed separately at a house or at other areas of water use. From this storing tank the collected pure water first passes through a UV tube for sanitation purposes and then is distributed among tanks of ambient temperature water, hot water, and cold water. The water is dispensed by turning on a push button type tap.

The water generator's refrigerant condenser is equipped with variable speed fans for regulating the quantity of outside air intake and controlling the production of water. The regulation of intake takes place by changing the RPM of the fans. This is executed by commands of a processor operating in accordance to a matrix of airflow predetermined for outside air temperatures and relative humidity (“RH”) combinations. The fans can periodically perform in reverse mode to expel dust and pollen from the air filters without shutting down the device. As a result, there is no need to complicate the filter assembly with sensors and other facilities to warn when the air filter is corked. In the reverse mode, the outside air first passes through the condenser where it is heated and then passes through the evaporator and air filter in reverse direction. Besides cleaning the filter, the reverse flowing hot air stimulates the evaporation of the liquid refrigerant in the evaporator and eliminates the freezing of evaporator. During the short period of air filter cleaning, the water generator continues to operate and water production is not interrupted. The periodicity of fan's reverse mode is predetermined and executed with the help of a timer connected to the electric circuit of the fan's motor.

To control refrigerant condensation, it is necessary to control the quantity and temperature of the mixture of cooled and dried air as well as the quantity and temperature of the outside air blown through the condenser. For this purpose, the water generator is provided with inward-opening revolving doors that are installed on both sides of the generator's air mixing chamber. The inward-opening revolving doors are located between the evaporator and the condenser for regulating the temperature and quantity of airflow through the condenser. Controlling the amount of airflow to the condenser is accomplished by automatically opening and properly positioning the revolving doors. A sampling servomechanism connected to the shaft of the doors can serve this purpose. The sampling servomechanism operates in response to the commands of a processor. The processor acts in accordance to a programmed matrix of required airflow through the evaporator under various combinations of air temperatures and relative humidity. All openings, doors and ports are equipped with gravity louvered screen doors, which automatically close the port to prevent penetration of insects and bacteria into the air mixing chamber when the generator is switched off.

The water generator is equipped with a special sensor system and operating mechanism for stopping the operation of the generator when ambient air temperature is lower than 20° C. and relative humidity is less than 35%. If ambient air temperature goes higher than 20° C. the sensor system and operating mechanism automatically restart the generator and the water supply is continued. If any one of the units of water generator is disabled the apparatus immediately stops functioning to deliver water to the tank of the dispensing block. If both the generator block's water tank and the dispensing blocks' water storing tank are full of water, the level control device switches off all parts of the generator.

In another preferred embodiment of the invention, the liquid refrigerant is sub cooled after it exits the condenser. This serves to increase the efficiency and the reliability of the water generator. To further increase compressor efficiency and reliability, the suction gas refrigerant is superheated after it exits the evaporator.

To increase efficiency and to prevent hydraulic shocks, an economizer is installed between the condenser and the evaporator. The economizer is connected by one side to the discharge line of the compressor and by opposite side to the suction line of the compressor.

It is preferable to minimize the total size of the evaporator and the condenser. To achieve this, software was developed to calculate the design characteristics of the generator and to determine the optimal quantity of ambient air passing through evaporator and condenser. This software is also useful for maintaining acceptable condensing temperature and pressure levels of the refrigerant, which is particularly important while operating under very high ambient temperatures.

In order to provide high quality potable water, the water extractor is equipped with a newly developed and constructed plate and tube type evaporator made of stainless steel, and the inside surface of water collecting tank of the extractor is covered by silver coating. Silver is a well known antimicrobial agent and helps maintain the purity of the water.

In addition, the preferred embodiment provides reliable operation of the compressor and water extractor using an oil separator is installed on discharge line of compressor. This oil separator is connected on the bottom side to the crankcase inlet pipe of the compressor and on the top side to the condenser. Also assisting with the operation of the compressor and water extractor is a liquid refrigerant separator installed on suction line of compressor. The liquid refrigerant separator is connected on the bottom side to the evaporator's inlet pipe and on the top side to the compressor.

To provide animate nature and structure water the extractor is equipped with music player chip installed near the water collecting tank and permanently playing classical music of Vivaldi, Mozart, Beethoven, Bach, and others.

The invented water generator does not need any type of energy consuming deicing system and, therefore, it is energy efficient and simplified by construction. It can easily be assembled from prefabricated equipment, elements and modules.

The present water generating apparatus provides lower initial cost, provides higher energy efficiency, is cost effective, and is ecologically safe. Thanks to the indicated series of advantages the cost of producing water with this machine is much cheaper compared to bottled water.

DETAILED DESCRIPTION OF THE INVENTION

The working components are enclosed in an air mixing chamber2formed by front panel4with intake air inlet port10and intake air filter11, rear panel5, vertical right side panel6with an inward-opening revolving door17with shaft18, vertical left side panel7with an inward-opening revolving door17with shaft18, top panel8with sampling servomechanism19and position command generating processor20, as well as the compressor chamber3and ventilation grills22.

In the perspective view of an embodiment of the water generating block ofFIG. 4is shown the rear panel5of the air mixing chamber2on which is located a port13for outlet of processed and dried air. The port13is equipped with a gravity type louvered screen14that automatically closes for preventing the penetration of insects and dust in the air mixing chamber2when water generating block is switched off. On the vertical right side panel6of the mixing chamber2is installed an inward-opening revolving door17for inflow of outside air and mixing with dried cooled air allowing air mixture of higher quantity and lower temperature which passes through the condenser15mounted on the rear panel5of the mixing chamber2(seeFIG. 5). The noted air mixture of higher quantity and lower temperature provides better cooling and efficient condensation of the refrigerant in the condenser which is especially needed when the generator operates under very hot and humid climatic conditions.

FIG. 5. is a cut-away inside perspective view of the water generating block with the left side vertical panel7of air mixing chamber2removed to show the evaporator12mounted on intake air inlet port10. The intake air inlet port10has an easily replaceable air filter11. A water receiving tray26is installed under evaporator12for collecting by gravity the water drops extracted from cooled air on the food graded coated surface of evaporator12. On the outlet air port13of the rear panel5the condenser15is mounted. InFIG. 5the inside perspective view of compressor chamber3is also represented. The compressor chamber3is completely separated from the mixing chamber2by bottom panel9for preventing hot air penetration from compressor chamber3into the air mixing chamber2which can result in changes of predetermined temperature regimes of the condenser and evaporator.

FIG. 6represents a perspective view of the core of water generating block with interconnections of all functional parts including: evaporator fin tube coil12, water receiving tray26, condenser fin tube coil15with variable speed reverse fan16and gravity type louvered screen14, and a refrigerant temperature regulating valve (“TRV”)24mounted on liquid refrigerant line. The implementation of the variable speed reverse fan16allows cleaning of the intake air filter by means of reverse air stream periodically blown through the air filter in reverse direction without stopping the generator. This method of filter air cleaning increases the water generation efficiency.FIG. 6represents also the perspective view of interconnections of the compressor21with its suction33and discharge34tubes, ventilation fan23, water collecting tank25, water solenoid valves27and29, water pump31, cascade of water filters32, water supply pipe30to the dispenser block.

FIG. 7,FIG. 8,FIG. 9andFIG. 10are respectively the front view, rear view, right side vertical view and left side vertical view of the basic embodiment of the present invention. The figures include front4, rear5, right side6and left side7vertical panels of the air mixing chamber2with both of the inward-opening revolving doors17, shafts18connected to the sampling servomechanism19and revolving doors required positions command generating processor20on the top panel8. In the mentioned figures are shown all four side vertical views of the compressor chamber3including: compressor21with refrigerant suction33and discharge34piping, water collecting tube connected to the water collecting tank25, water pump31, cascade of water filters32, water supplying pipe30with water solenoid valve29, water recirculation pipe with solenoid valve27, compressor chamber ventilation grills22and compressor's cooling ventilation fan23.

FIG. 11andFIG. 12represent respectively the perspective view and top view of the compressor chamber3of the water generation block of the present invention. The figures show the arrangement of main equipment including: compressor21, refrigerant suction33and discharge34pipes, water collecting tank25, water pump31, cascade of water filters32, water supplying pipe30with solenoid valve29, water recirculation pipe28with solenoid valve27, ventilation grills22and compressor's cooling ventilation fan23. The ventilation fan23serves for improving operation conditions of the compressor by its effective cooling which is essential in hot climatic conditions.

The water in the collecting tank25is periodically re-circulated through the cascade of water filters32by pump31and recirculated by bypassing pipe28and opened water solenoid valve27. The repeated circulation of generated water through the cascade of water filters by the action of the pump31allows using high rate and small-pore, adsorption media such as a porous-carbon block in the NSF-53 certified filter for filtration of the water from organic compounds, insects, organic contaminants and heavy-metal compounds to purifying the water in accordance with ASHRAE and U.S. federal standards. During the recirculation the solenoid valve29is closed. A timer connected to solenoid valves27and29controls the predetermined duration of recirculation. When the water in the tank25is purified the timer closes the solenoid valve27and opens the solenoid valve29and pure water is pumped via the water supplying pipe30to the water storing tank35of the water dispensing block.

FIG. 13is a perspective view of an embodiment of a water dispensing block of the present invention, showing the arrangement of main equipment including: purified water storing tank35connected to the water supplying pipe30coming from water generator block. The water storing tank35is equipped with air eliminator and water level controlling sensors44, UV tube36. The pure potable water flows through the UV tube by gravity into the hot water insulated tank37having electric heater42and cold water insulated tank38having cooling coil41of a water chiller consisting of a compressor39, condenser40and TRV. The cold, hot and ambient temperature waters are delivered to users trough push button taps43mounted on corresponding delivering tubes.

The water level in the water storing tank35is controlled by electrically-operated sensor switch44, which causes the pump31to cease operation when the water storing tank35is filled. When both water storing tank35of the dispenser block and water collecting tank25of the water generator block are filled the electrically-operated sensor switch stops both compressor21and water pump31of the water generator block. When water storing tank35of the dispenser block is full of water and water collecting tank25of the water generator block is empty or not completely filled the electrically-operated sensor switch stops the water pump31of the water generator block but compressor21continues operating for producing water to fill the water collecting tank25of the water generator block.

Operation of the Apparatus of the Invention

The compressor unit21installed at the bottom of compressor chamber3of the water generator block1exhausts the refrigerant's vapors from the evaporator12by the refrigerant suction tube33and after having compressed it up to the condensation pressure forces into the condenser15by discharge pipe34. The ribbed pipe type condenser15is mounted on the rear panel5of the housing of air mixing chamber2of water generator block1. The condenser15is equipped with direct and reverse rotating variable speed exhausting fan16. In the condenser15the vapor of refrigerant transfers its latent heat to the mixture of cooled and outside air that is exhausted through the heat transfer surface of the condenser15by the help of fan16. As a result of heat exchange the air mixture is heated and evacuated outside and the vapor of the refrigerant transforms into liquid and then passes through the temperature regulating valve (“TRV”)24. In the TRV24the pressure of the liquid refrigerant is decreased to a value that provides temperature of the liquid refrigerant below the value of dew point of intake outside air. The cold liquid refrigerant enters into the evaporator12and fixes temperature on its surface approximately equal to the temperature of liquid refrigerant.

The direct and reverse rotating variable speed fan16draws the outside air into the inside space of air mixing chamber2of the water generator block1. Incoming outside air first is filtered through tightly-sealed and easy replaceable filter11fitted on the air intake port10of the front vertical panel4of air mixing chamber2for removing particulates, insects, dust and aerosols from the incoming air. Then the incoming air passes through finned tube evaporator12coated with special inert food grade painting. The cold refrigerant keeps the surface temperature of the evaporator lower than the dew point temperature of air. In consequence of the heat exchange the intake outside air is cooled and the water vapor contained in the air is condensed on the food graded coated surface of evaporator12. In this heat exchange process the liquid refrigerant transforms into gas (vapor) and sucked again back into the compressor21. The water from the surface of the evaporator drips by gravity into a receptor tray26installed under the evaporator12. From receptor tray26the water by a tube runs by gravity into a water collecting tank25.

The processed and dried air mixture is evacuated outside through the condenser15and outlet port13installed on the rear panel5of the air mixing chamber2. The outlet port13is equipped with gravity type louvered screen14which is opened under air-blast and automatically closes and provides the tightness of air mixing chamber2for preventing the penetration of insects and dust when water generating block is switched off.

For controlling the temperature of condensation under variable temperatures of outside air it is necessary to draft variable quantity of air through the condenser15. For regulating the quantity and temperature of air that has to pass through the condenser15, a mixture of dried and cold air exiting from the evaporator12and outside air is used. To prepare the mixture of airs the water generator is equipped with inward-opening revolving doors17installed on both right6and left7side vertical panels of air mixture chamber2and located between evaporator12and condenser15. The preparation and use of air mixture provide better cooling and efficient condensation of the refrigerant in the condenser15that is especially needed when the generator operates under very hot and humid climatic conditions.

The revolving doors17are equipped with air filters and are fixed on shafts18, which revolve by a sampling servomechanism19serving to regulate the automatic opening/closing and proper positioning of revolving doors17. The sampling servomechanism19operates in response to commanding generating processor20in accordance with a programmed matrix of required outside air flow through the evaporator and condenser under various combinations of outside air temperatures and relative humidity. The higher the outside air temperature, the wider the doors are opened. When at the same time ambient air temperature is lower than 20° C. and relative humidity is less than 30-35%, the sensors system and operating mechanism stop running the water generator and hermetically close the revolving doors17for preventing penetration of insects and bacteria into the cabinet of the generator.

If ambient air temperature during daytime grows higher than 20° C. the sensors system and operating mechanism automatically restart the compressor21, air fans23and open the revolving doors17up to the proper position according to the ambient temperature and relative humidity. Thus, the water generation, purification and its pumping to the tank of water dispensing block continues.

Variable speed fans23serve also for regulating the flow of intake outside air according to a matrix of combinations of outside air temperatures and relative humidity. The noted matrix is programmed in the processor20which controls the reliable and efficient operation of refrigerant compressor21and as well as the water productivity of the apparatus in accordance with variable temperatures and relative humidity. The intake air filter11does not need to be equipped with sensors and other facilities to warn when the air filter is corked, as reverse rotating fan23periodically operates in reverse direction. In this regime the stream of outside air periodically blows first through the condenser15where it is heated and then passes through the evaporator12and afterwards through the air filter11where it blows out the dust and pollen from the air filters11. Besides cleaning the filter11, the hot air evaporates liquid refrigerant in the evaporator12and helps to prevent the freezing of evaporator12. During the filter cleaning the water generator continues operating and water production is not interrupted which saves energy. The periodicity of the fan's reverse operation for cleaning the air filter11is predetermined and executed by the help of a timer connected to the electric circuit of the fan's motor.

The water collected in tank25is periodically circulated through the cascade of water filters32by pump31and recirculated through bypassing pipe28and opened water solenoid valve27back to tank25. The repeated circulation of generated water through the cascade of water filters32by pump31allows using high rate and small-pore, adsorption media such as a porous-carbon block in the NSF-53 certified filter for filtration the water from organic compounds, insects, organic contaminants and heavy-metal compounds to purifying the water in accordance with ASHRAE and U.S. federal standards. During the recirculation the solenoid valve29is closed. A timer connected to solenoid valves27and29controls the predetermined duration of recirculation. When the water in the tank25is purified the timer closes the solenoid valve27and opens the solenoid valve29and pure water is pumped through water supplying pipe30to the water-storing tank35of the water-dispensing block. The ambient temperature water from collecting tank25flows by gravity through UV tube36into the hot water tank37and constantly is heated by electric heater42. For delivering hot water the push button tap43mounted on hot water conducting tubing is pressed and the hot water from the tank37by gravity flows to the user. The temperature of hot water is controlled on the level 90° C. by incorporated thermostat. For preparing cold water the dispensing apparatus includes its own refrigerating machine consisting of compressor39, condenser coil40and evaporator coil41, which is fitted on the surface of cold-water tank38. For delivering cold water the push button tap43that is mounted on cold water conducting tubing is pressed and the water from cold-water tank38flows through the UV tube36to the user. A cold-water temperature sensor and switch assembly controls the operation of refrigerator machine to maintain the predetermined temperature of the cold water at about 5° C. For delivering ambient temperature water the push button tap43mounted on water conducting tubing is pressed and the ambient temperature water from water storing tank25by gravity flows through the UV tube36to the user.

The water-storing tank35is equipped with air eliminator and water level controlling sensors. The water level in the water-storing tank35is controlled by the electrically-operated sensor switch44, which causes the pump31to cease operation when the water-storing tank35is filled. In the case of when both water storing tank35of the dispenser block and water collecting tank25of the water generator block are filled the electrically-operated sensor switch44stops at once both compressor21and water pump31of the water generator block. In the case of when water storing tank35of the dispenser block is full of water and water collecting tank25of the water generator block is empty or not completely filled the electrically-operated sensor switch44stops the water pump31of the water generator block but compressor21continues operating for producing water to fill the water collecting tank25of the water generator block.

In another preferred embodiment of the invention designed to prevent hydraulic shocks, the liquid refrigerant is sub cooled after it exits the condenser15, the suction gas refrigerant is superheated after it exits the evaporator12, and an economizer101in the form of an intermediate heat exchanger is installed between the condenser15and the evaporator12. The economizer101is connected by one side to a discharge line102of the compressor21and by opposite side to the suction line104of the compressor21.

Software was developed to determine the optimal quantity of ambient air passing through the evaporator12and the condenser15. This software is also useful for maintaining acceptable condensing temperature and pressure levels of the refrigerant.

The water extractor is equipped with a newly developed and constructed plate and tube type evaporator105made of stainless steel, and the inside surface of water collecting tank25of the extractor is covered by silver coating.

In addition, an oil separator106is installed on a discharge line107of compressor21. This oil separator106is connected on the bottom side to the crankcase inlet pipe of the compressor21and on the top side to the condenser15. Also assisting with the operation of the compressor21and the water extractor is a liquid refrigerant separator103installed on the suction line104of the compressor21. The liquid refrigerant separator103is connected on one side to the evaporator's inlet pipe108and on another side to the compressor.

To provide animate nature and structure water the extractor is equipped with music player chip109installed near the water collecting tank and continuously playing sound.

The described system and method of automatic control provides high efficiency and productivity of the invented split type potable water extractor from ambient air and water dispenser.
