A multipurpose air conditioning unit for generating dew drinking water, hot water for bathing and hot air for drying clothes comprising: • air handling units connected to the outdoor air by fresh air ducts, connected to the rooms by return air ducts and supply air ducts, said air handling units comprising air flow dampers for mixing outdoor air from the fresh air ducts and return air from return air ducts into mixing air ducts; pre air filters, medium air filters and UV lights for filtering and sterilizing the resulting mixing air installed in the mixing air ducts, evaporator coils for condensing water vapour from mixing air installed in the mixing air ducts, whereby the evaporator coils are arranged downstream of the UV lights and upstream of blower fans for supplying cold fresh air to rooms along the supply air ducts, • a drip pan arranged under each evaporator coil for collecting dew droplets from said evaporator coils, • water pipes for channeling water from said drip pan to a dew water storage tank, • a dew drinking water pump is connected to said dew water storage tank, • water filters and UV lamp tube installed on said water pipes for sterilizing water and all parts which are passed by the condensate water, including the evaporator coils, the drip pan, all pipes and the dew drinking water pump, are made of food grade metal, • a compressor, a discharge line and a discharge line cooler, air cooled condensers, a liquid receiver, a filter dryer, a sight glass, a solenoid valve, and expansion valves arranged for passing refrigerant vapor, from the compressor through the discharge line along the discharge line cooler to the air cooled condensers for sub-cooling the refrigerant vapor and arranged for further passing the refrigerant through the liquid receiver, the filter dryer, the sight glass, the solenoid valve, the expansion valves and along the evaporator coils back to the compressor, whereby the discharge line cooler comprising a hot water tank filled with municipal water or other waters, through which the discharge line is passed, thereby producing hot water for bathing supplied by a hot water pump and • a cabinet with dryer hanger steel bar for drying clothes arranged for receiving hot air produced from the air cooled condenser, the air conditioning unit further comprising a thermostat for controlling room temperature, an air flow controller, a high and low pressure controller for maintaining the compressor in a safe mode, an oil pressure controller for assuring that the oil is always available in the compressor and an air differential pressure controller for giving sign if the air pre filter and medium filter are dirty and need to be replaced. • air handling units connected to the outdoor air by fresh air ducts, connected to the rooms by return air ducts and supply air ducts, said air handling units comprising air flow dampers for mixing outdoor air from the fresh air ducts and return air from return air ducts into mixing air ducts;
