## Background
CROSS REFERENCE OF RELATED APPLICATION
This is a U.S. National Stage under 35 U.S.C 371 of the International Application PCT/CN2012/001054, filed Aug. 7, 2012, which claims priority under 35 U.S.C. 119(a-d) to CN 201210075894.1, filed Mar. 21, 2012.
BACKGROUND OF THE PRESENT INVENTION
1. Field of Invention
The present invention relates to a field of indoor temperature regulation equipment, and more particularly to a double-medium circulation air conditioner for cooling, heating and humidifying.
2. Description of Related Arts
The conventional refrigerant circulation air conditioner and water-cooled air conditioner have been widely applied in various fields of social life and production. However, due to limitation of the structure and working principle thereof, the application of the conventional refrigerant circulation air conditioner has both advantages and disadvantages.
Referring to FIG. 1 of the drawings, the refrigerant circulation air conditioner comprises two parts of an indoor part A and an outdoor part B, which is complicated in structure and requires professionals for installation and maintenance. In the air conditioner, a capillary tube 1, a check valve 2, a refrigerant evaporating pipe 3 and an indoor part heat exchanging fan 4 and etc. are provided in the indoor part A, and a four-way valve 9, a liquid storage tank 5, a compressor 6, an outdoor part heat exchanging fan 8 and a refrigerant condenser 7 and etc. are provided in the outdoor part B. Four-way connectors of the four-way valve 9 are respectively connected with the refrigerant evaporating pipe 3, the liquid storage tank 5, the compressor 6 and a first end of the refrigerant condenser 7 via the pipe 10, and a second end of the refrigerant condenser 7 is connected with the refrigerant evaporating pipe 3. The liquid storage tank 5 is connected with the compressor 6. The capillary tube 1 and the check valve 2 are connected in parallel and installed between the refrigerant condenser 7 and the refrigerant evaporating pipe 3.
When this type of air conditioner is processing refrigeration operation, the high pressure gas refrigerant is discharged from the compressor 6 and sent to the refrigerant condenser 7 of the outdoor part B via the pipe 10, so as to process heat dissipation via the outdoor part heat exchanging fan 8 to obtain high pressure liquid refrigerant, then process pressure reducing and throttling through the capillary tube 1, in such a manner that the refrigerant is converted to a low pressure liquid and flows into the refrigerant evaporating pipe 3 of the indoor part A to absorb heat of indoor air via the indoor part heat exchanging fan 4, and then the refrigerant returns back to the compressor 6 outdoor, in such a manner that the object of refrigeration goes round and begin again.
When the refrigerant circulation air conditioner is heating, the refrigerant flows in an opposite direction in the pipe with the flow direction of refrigerant while cooling by the action of the four-way valve 9. Under a low pressure, the gas refrigerant is compressed into a high temperature and high pressure gas, which is then sent into the refrigerant evaporating pipe 3 of the indoor part A to process heat dissipation therein via an indoor part heat exchanging fan, so as to change into a liquid thereafter. The liquid is then processed with pressure reducing and throttling through the capillary tube 1 of the pipe 10, then returns to the refrigerant condenser 7 of the outdoor part B to be processed with heat absorption by the heat exchanging fan 8 of the outdoor part. Then the refrigerant returns back to the compressor to achieve the object of heating continuously. It can be seen from the working principle that this kind of air conditioner processes the heating or cooling operation by dissipating heat outdoor and then absorbing heat indoor via the refrigerant, or otherwise by absorbing heat outdoor and then dissipating heat indoor, and thus the environmental temperature has great influence on the operation of the air conditioner. E.g., in the winter of northern China, when the temperature outdoor is ten degrees centigrade below zero or even tens of degrees centigrade below zero, heating by this type of air conditioner can not achieve satisfying effects, and the reason lies in that the refrigerant in the outdoor part B absorbs heat from the environment in a low efficiency, so that a satisfying heating effect can not be achieved. In addition, in hot summer, since this type of air conditioner dissipates heat outdoors in a low efficiency, cooling effect of the air conditioner is reduced heavily or even fails.
The water-cooled air conditioner as shown in FIG. 2 of the drawings, the structure and working principle thereof are relatively simple. The underground water 14 is directly pumped to the water-evaporator 11 by the water circulating pump 13. Heat of water is dissipated to the locating environment via the heat exchanging fan 12. Since the temperature of the underground water is always in a range of 16 ̃19 degrees centigrade, the effects of cooling in summer and heating in winter can be achieved. However, due to temperature limitation of underground water source, temperature regulating capability of this type of air conditioner while heating is also limited to a certain range, which brings inconvenience to utilization thereof.
Meanwhile, since the air conditioner is only capable of getting a significant effect when being utilized in an enclosed space, the indoor environment is inevitably dry after utilizing the air conditioner for a long time, which is bad for respiratory system of human body and thus affects physical fitness of human beings.
Moreover, the utilization of the conventional air conditioner is manipulated by tact switch or close controller, remote control is difficult to achieve, and the indoor temperature can not be regulated to an adaptable degree in advance, which are problems of the conventional air conditioner to be solved immediately.
Thus, how to adjust for combining the advantages of the two kinds of air conditioners and overcoming disadvantages thereof, so as to further improve the utility of the air conditioners, i.e., achieving the regulating the indoor temperature freely and effectively even under harsh climate conditions, and adjusting humidity while changing the indoor temperature, in such a manner that the objects of controlling both the temperature and the humidity, and remote pre-control are achieved, has been a research focus for technicians in the field.

The water pump 34 is connected with an auxiliary shaft 24 through pipelines and capable of injecting water from the main shaft 17 into the auxiliary shaft 24. The water circulation system is a closed internal recycling system.
Lines of the refrigerant circulation system are indicated as dotted lines in FIG. 3 and FIG. 4 of the drawings. The refrigerant circulation system has a four-way valve 9 provided therein. Four-way connector of the four-way valve is respectively connected with a refrigerant evaporating pipe 3, a liquid storage tank 5, a compressor 6 and a first end of the refrigerant heat exchanging pipe 22. A second end of the heat exchanging pipe 22 is connected with the refrigerant evaporating pipe 3. The liquid storage tank 5 is connected with the compressor 6. A capillary tube 1 and a check valve 2 are connected in parallel between the refrigerant heat exchanging pipe 22 and the refrigerant evaporating pipe 3. A refrigerant filter 15 is provided between the capillary tube 1 and the refrigerant evaporating pipe 3.
As shown in FIG. 6 of the drawings, a composite enclosure 38 is covered on an external of the compressor 6. As shown in FIG. 7 of the drawings, the composite enclosure 38 comprises an acoustic absorbent fabric layer 39, an acoustic panel layer 40 and a metal shell layer 41 from inside out. The composite enclosure 38 is capable of effectively blocking out noises generated by the operation of the compressor 6. An upper portion of the machine body 35 has an air inlet 37 and an air outlet 36 provided therein. A heat exchanging fan 12 is provided in the air outlet 36. A water-evaporator 11 and a refrigerant evaporating pipe 3 are provided between the air outlet 36 and the heat exchanging fan 12.
When the air conditioner of the present invention is in utilization, the water circulation system can be turned on individually for processing cooling operation, and working principle thereof is the same as the conventional water-cooled air conditioner. In addition, the two sets of systems can also be turned on simultaneously according to requirements, so as to processing heating or cooling operation high efficiently. Therefore, taking the example of turning on the two systems simultaneously for processing cooling operation, working principle and working process of the air conditioner of the present invention are briefly illustrated as follows.
During the cooling operation of the air conditioner, a water circulating pump 13 of the water circulation system 33 drives cold water in the downhole heat exchanger 33 to pass through the inlet pipe 18 and enter the water-evaporator 11. The heat exchanging fan 12 drives airflow to pass through the water-evaporator 11, so as to blow the cold air into the indoors for achieving cooling effect. Then the recycled water flows into the water heat exchanging pipe 20 of the downhole heat exchanger form the return pipe 16, so as to flow back to the downhole heat exchanger 33 for processing heat exchange with water in the main shaft 17, so as to process heat elimination and temperature reduction to achieve operation of the water circulation system.
Meanwhile, the compressor 6 of the refrigerant circulation system discharges high temperature and high pressure gas refrigerant, which is then sent to the refrigerant heat exchanging pipe 22 through the refrigerant recirculating line 23. The refrigerant is processing heat exchanging with the water heat exchanging pipe 20 of the heat exchanger 21 while circulating in the heat exchanging pipe,
Meanwhile, the compressor 6 of the refrigerant circulation system discharges high temperature and high pressure gas refrigerant, which is then sent to the refrigerant heat exchanging pipe 22 through the refrigerant recirculating line 23. The refrigerant is processing heat exchanging with the water heat exchanging pipe 20 of the heat exchanger 21 while circulating in the heat exchanging pipe, i.e., utilizing the recycled water to take away heat exchanging with indoor air, so as to be dissipated in the main shaft 17. After heat dissipation, the refrigerant turns into high pressure liquid, and then turns into low pressure liquid by pressure reducing and throttling of the capillary tube 1, so as to flow into the refrigerant evaporating pipe 3, absorb heat of indoor air via the heat exchanging fan 12, then return to the compressor 6, in such a manner that the object of cooling continuously is achieved.
During the process mentioned above, a critical step is the heat exchanging step of the heat exchanger 21. Since in hot season, the underground water in the main shaft 17 is far below the environmental temperature outdoors of 30 ̃40° C. Thus, the heat dissipation and temperature reduction effects of the refrigerant in the heat exchanger 21 are far better than the effects thereof in the outdoor part of the conventional air conditioner, and thus the cooling effects of the air conditioner of the present invention are far better than the conventional air conditioner.
The principle and process for the two systems to process heating is similar to the principle and process during cooling. The difference lies in that under the effect of the four-way valve 9, flow direction of the refrigerant is in the opposite direction with the direction thereof while cooling. Under a condition of low pressure, the gas refrigerant is compressed into a high temperature and high pressure gas refrigerant by the compressor 6, sent to the refrigerant evaporating pipe 3, processed with heat dissipation indoors via the heat exchanging fan 12 to form a liquid, then processed with pressure reducing and throttling by the capillary tube 1, so as to return back to the refrigerant heat exchanging pipe 22. The refrigerant processes heat exchanging with the water heat exchanging pipe 20 of the heat exchanger 21 while circulating in the refrigerant heat exchanging pipe 22, so as to carry off cooling capacity discharged indoors, and then discharges the cooling capacity to underground well by the downhole heat exchanger 33 in the main shaft. Finally, the refrigerant returns to the compressor 6, so as to achieve an object of heating continuously. Since in cold season, temperature of the underground water is far higher than the environment temperature outdoors of ten degrees centigrade below zero or even tens of degrees centigrade below zero. Thus, the refrigerant has a better heat absorption effect when provided in the heat exchanger 21, which is far better than the effect thereof when provided in the outdoor part of the conventional air conditioner, and thus the heating capability of the air conditioner in the present invention is far better than thereof the conventional air conditioners.
During the utilization of the present invention, in order to achieve a better effect, the water pump 34 communicated between the main shaft 17 and the auxiliary shaft 24 can be turned on regularly, so as to inject the water which is warmed by heat exchanging into the auxiliary shaft 24, wherein underground water which has a relatively low temperature around the main shaft 17 refills the main shaft 17, in such a manner that the main shaft 17 maintains in a constant temperature, and that the heat exchanging effect of the radiator 33 is higher.

Each water-storage grill 25 has three atomizers provided therein. A water pump 30 of the humidification system is provided in a water tank 29, the water thank 30 is connected with a filler pipe 31. The filler pipe 31 is communicated with an upper portion of the humidifying water-storage grill set 32, a lower portion of the humidifying water-storage grill set 32 is connected with a drain 28, and the drain 28 is connected with the water tank 29.
When the air conditioner of the present invention is in use, the water pump 30 injects liquid in the water tank 29 into a first water-storage grill 25. When one water-storage grill is filled, the liquid flows into a water-storage grill below, and flow direction is in a shape of “S”. Until water level of all of the water-storage grills exceeds the atomizer 26, the atomizer 26 begins to work, so as to atomize water to ultrafine particles utilizing principle of ultrasonic wave high frequency oscillation principle. The ultrafine particles of water are spread to the air, so as to achieve an object of humidifying the air uniformly.
Furthermore, different kinds of aroma essential oil and concentrated liquid of tradition Chinese medicine can be added into the water tank 29, so as to achieve an object of medical care.
