DESCRIPTION OF THE PREFERRED EMBODIMENTS
A system for purification of air in an inner space in accordance with the present invention has a housing 1(FIGS. 1, 2 and 4) provided with an inlet 2 and an outlet means 3 for entry of air into the housing 1 and exit of air from the housing 1.
Filtering means are located in the housing 1 and can include a prefilter 4 and filter 5. Flaps 6 can be provided before the prefilter 4 so that when they are open air goes through prefilter 4 and around the filter 5, and when the flaps 6 close the passage between the filter 5 and the housing 1, the air also flows through the filter 5.
A ultraviolet device 7 is located after the filtering means and emits ultraviolet radiation to purify the air by killing germs, etc.
After the ultraviolet device 7 an air conditioner 8 is located which cools the air passing from the inlet 2 to the outlet 3 through the housing 1.
A fan 9 provides suction of air from the inlet 2 to the outlet 3 through the prefilter 4, filter 5, the ultraviolet device 7, air conditioner 8, and a humidifier 10.
The humidifier 10 is connected with a water container 11 through a pipe 12. Another pipe 13 connects the outlet of the air conditioner 8 with the water container 11 to supply a discharge water from the air conditioner 8 into the water container 11. A filter 14 can be located in this pipe 13, and an additional pump 16 can move water from the air conditioner 8 into the water container 11. Reference numeral 17 identifies a tray with additional pump for condensed water from the air conditioner 8 to the outside.
The air conditioner 8 has a compressor 18, which pumps a cooling fluid through the air conditioner 8. The passing air heats said cooling fluid.
The system further has a heat exchanger 19. It provides a heat exchange between the heated cooling fluid from the air conditioner 8 and a cool cooling liquid, which cools the heated cooling fluid.
Reference numeral 20 identifies a valve for ventilation, to supply a fresh air from outside.
The system further has a flexible pipe or hose 21 (FIGS. 2, 5) from taking air, in which the allocated a pipe 22 for supplying a cold water to the heat exchanger 19 and a pipe 25 for withdrawing a heated water from the heat exchanger 19. A cooler 23 cools the cooling water or radiator provided with two ventilators 24, which can operate individually or jointly in accordance with a program.
An additional exterior air can be supplied through the pipe 21 into the interior of the housing 1.
The air humidifier 10 shown in FIG. 3 has a negative electrode 26 formed by a plurality of silver wires located on sections of the humidifier 10, and a positive electrode 27, which is formed by a bottom net. A circulating pump 28 is further provided for supplying water. There is a gap between the silver wires of the negative electrode 26 and the net of the positive electrode 27. This gap is breached by water when it flows through the humidifier 10, thus causing movement of negative ions of silver from the negative electrode 27 to the positive electrode and impregnating water with silver ions, which provide bactericidal properties to water.
A control unit 29 controls the operation of the inventive system. It can turn on and off of each individual unit of the system by an operator, or remotely, and even through an Internet.
As shown in FIG. 2, the system further has an aroma producing element 30 operated for adding aroma to the air passing from said inlet means to said outlet means, said aroma adding means is configured so as to provide different aromas into the air, ionizer 32 and ozonizer 33 which located in the area of the outlet means 3 of the system. The outlet means 3 is connected with an attachment 31, which is formed as a vertical attachment. With the vertical attachment 31 the air leaves the housing 1 at a substantially higher level through then the inlet 2, thus providing a significant advantage in proper purification of air.
The attachment 31 has inside the humidifier 10 which connected to the water container 11. The humidifier 10 is installed inside said vertical attachment 31. The water container 11 is installed inside the housing 1.
In the system either air from a room or outside air can be introduced into the housing 1. When flaps 6 are open and a valve 20 is closed, air from the room is introduced into the housing 1, while when the flaps 6 are closed and the valve 20 is open air from outside is introduced into the housing 1 into the housing 1 through the pipe 21
It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of constructions differing from the type described above.
While the invention has been illustrated and described as embodied in a system for purification of air in an inner space, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of the present invention.
Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, be applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.
