ABSTRACT:
A method for removing humidity from air comprising the steps of providing an air conditioning system comprising a continuous circuit through which a refrigerant flows from a compressor, through a condenser, through a heat exchanger, through an evaporator, and returning to the compressor, providing a bypass valve through which a portion of the refrigerant flows around the heat exchanger, providing a bypass circuit through which a portion of the refrigerant flows from a point upstream of the condenser to mix with the refrigerant at a point downstream of the condenser, providing a discharge gas valve for controlling the portion of the refrigerant flowing through the bypass circuit, measuring an outdoor temperature and a relative humidity, determining a cooling stage and operating the bypass valve and the discharge gas valve to remove a portion of the humidity from the air based upon the outdoor temperature, the relative humidity, and the cooling stage.
