A method and machine for producing fresh and cool air, dew drinking water, hot air for the dryer, hot water for bathing or other purposes using an energy-saving and environmentally-friendly multipurpose air conditioning as a generator of dew drinking water, hot water and dryer. Mixture of fresh outdoor air and returned air from the rooms passed to the evaporator coils to condense the moisture from the air to produce pure and fresh dew drinking water and cool fresh air, where the air is then flown back into the room. Municipal water or other water then dip the hot discharge line to subcool the refrigerant before entering the condenser thus saving energy and at the same time produce hot water that can be used for bathing or other purposes. Hot air coming from air-cooled condensers can be used as a dryer.
