Brief Description of the Drawing

To explain this invention, will be illustrated in the accompanying drawing:

Figure 1 shows a schematic drawing not to scale of energy-saving and environmentally-friendly multipurpose air conditioning as a generator of dew drinking water, hot water and dryer.

Detailed Description of the Invention

The following description will explain in detail the energy-saving and environmentally-friendly multipurpose air conditioning as a generator of dew drinking water, hot water and dryer.

In accordance with Figure 1, compressor (1) will sucked refrigerant vapour coming from the evaporators (15) through the suction line (3) and compress it at high pressure and temperature and then circulate to the air cooled condenser (5) through the discharge line (2). In the discharge line (2) there is a discharge line cooler (4) where the municipal water (35) cools the discharge line to subcool the refrigerant vapour and thus saving the energy and at the same time producing hot water (13) which can be used as shower or else. The air cooled condenser (5) is cooled by the outdoor air (31), and the hot air (14) after passing the condenser is flown to the cabinet which has dryer hangers which can be used as a clothes dryer or else. After passing the air cooled condenser (5), the refrigerant then passed to the liquid receiver (6), through the filter dryer (7), sight glass (8) and solenoid valve (9) in the liquid line (11) and then to the expansion valves (10). After the refrigerant being expanded in the expansion valve, then the refrigerant pressure and temperature will drop signifantly and enter to the evaporators (15) where it will cool the mixing air (33) of the mixing air ducts (26) which is a mixture of fresh outdoor air (31) of the fresh air ducts (24) and return air from the room (32) of the return air ducts (25) by controlling through a dampers (16), and at the same time condense its moisture. Before the mixing air (33) entering the evaporators (15), it is passed through the air pre filters (17) and the medium filters (18) to be eliminated from the dust, dirt, and other polutant. Then the mixing air (33) is passed to the ultraviolet lights (19) to kill the bacteria and pathogenic mold to sterilize the air. The drip of the condensation as dew drinking water (30) will be collected to the drip pans (20) and then will be passed to the water filters (36) and UV lights tube (21) which is again will kill the bacteria and pathogenic mold in the dew water and is ready to be pumped by the water pump (23) to the storage tank (22). In the mean time the cold fresh air (34) after being removed its moisture in the evaporator coils (15) is then circulated by the blowers (28) to the rooms (29) through supply air ducts (27) so that the cold supply air (34) will enter the rooms (29). After leaving the evaporators (15) then the refrigerant will enter the compressor again (1) to be compressed at high pressure and temperature.

It is important to control so that the fresh air is cooled at the dew point so that the moisture will condense at this point. It is necessary to control the air flow. It is also necessary to control the refrigerant pressure to a minimum and maximum allowable pressure to maintain the compressor (1) in a safe condition. Oil pressure control is also necessary to make sure that the oil is always present in the compressor (1). If the air pre filters (17) and medium filters (18) are dirty and need to be replaced, so it is necessary to have a control to make a sign that those filters should have to be changed.
