     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0010]    A system for purification of air in an inner space in accordance with the present invention has a housing identified with reference  30  and provided with an inlet  40  and an outlet  50  for entry of air into the housing and exit of air from the housing. 
         [0011]    Filtering means are located in the housing and can include a prefilter  1  and a HEPA filter  2 . Flaps can be provided on a periphery of the HEPA filter  2 , so that when they are open air goes through prefilter  1  and around the HEPA filter, and when the flaps close the passage between the HEPA filter and the housing, the air also flows through the HEPA filter. 
         [0012]    An ultraviolet device  3  is located after the filtering means and emits ultraviolet radiation to purify the air by killing germs, etc. 
         [0013]    After the ultraviolet device an air conditioner  4  is located which cools the air passing from the inlet to the outlet through the housing. 
         [0014]    A fan  6  provides suction of air from the inlet to the outlet through the filtering means  1 ,  2 , the ultraviolet device  3 , air conditioner  4 , and a humidifier  5 . 
         [0015]    The humidifier  5  is connected with a water container  7  through a pipe. Another pipe connects the outlet of the air conditioner  4  with the water container  7  to supply a discharge water from the air conditioner  4  into the water container. A filter can be located in this pipe, and an additional pump can move water from the air conditioner  4  into the water container  7 . Reference numeral  9  identifies a tray for collecting water (condensed water) from the air conditioner. The pipe for supplying the condensed water into water container is identified with reference numeral  7  and the corresponding pump is identified with reference numeral  11 . 
         [0016]    The air conditioner  4  has a compressor which pumps a cooling fluid through the air conditioner which is heated by the passing air, and for sucking the heated cooling fluid, for example Freon. 
         [0017]    The system further has a heat exchanger which is identified with reference numeral  13 . It provides a heat exchange between the heated cooling fluid from the air conditioner and a cool cooling liquid, which cools the heated cooling fluid. 
         [0018]    Reference numeral  14  identifies a valve for ventilation, to supply a fresh air from outside. 
         [0019]    The system further has a flexible pipe or hose from taking air, in which the allocated a pipe  17  for supplying a cold water to the heat exchanger and withdrawing a heated water from the heat exchanger. The cooling water is cooled by a cooler or radiator  20  provided with two ventilators  21  which can operate individually or jointly in accordance with a program. 
         [0020]    Reference numeral  18  identifies a pipe for withdrawing an excess of water and reference numeral  19  identifies a pump for displacing the excessive water. 
         [0021]    An additional exterior air can be supplied through the pipe  15  into the interior of the housing. 
         [0022]    The air humidifier  5  shown in  FIG. 3  has a negative electrode  22  formed by a plurality of silver wires located on sections of the humidifier, and a positive electrode  23  which is formed by a bottom net. A circulating pump  24  is further provided for supplying water. There is a gap between the silver wires of the negative electrode and the net of the positive electrode. This gap is breached by water when it flows through the humidifier, thus causing movement of negative ions of silver from the negative electrode to the positive electrode and impregnating water with silver ions, that provide bactericidal properties to water. 
         [0023]    A control unit  25  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. 
         [0024]    As shown in  FIG. 2 , the system further has an aroma producing element which is identified with reference numeral  26  and located in the area of the outlet means  50  of the system. The outlet means  50  is connected with an attachment  27  which is formed as a vertical attachment. The vertical attachment  27  can have a height substantially between 3′ and 10′. With the vertical attachment the air enters the housing at a lower level, and leaves the housing at a substantially higher level through an outlet of the attachment  27 , thus providing a significant advantage in proper purification of air. 
         [0025]    The attachment  27  can be formed as a lamp, a sculpture, a column, a tree, fallows, etc. 
         [0026]    In the system either air from a room or outside air can be introduced into the housing. When flaps  31  are open and a valve  32  is closed, air from the room is introduced into the housing, while when the flaps  31  are closed and the valve  32  is open air from outside is introduced into the housing into the housing through the pipe  15 . 
         [0027]    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. 
         [0028]    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. 
         [0029]    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.
