Described are heat pump systems and methods for conditioning air, in which air is dehumidified including the steps of passage over an evaporator to cool and dehumidify the air, followed by passage over a subcooler to heat the air prior to passage into a space to be conditioned. Also described are heat pump systems and methods for conditioning air, in which air is heated by passage over a subcooler followed by passage over a condenser. The methods and systems are readily implemented and highly effective in improving system capacity.

A method for dehumidifying air, comprising: condensing refrigerant in a condenser; expanding refrigerant after exiting the condenser in a pressure reduction device to a predetermined pressure above an evaporating pressure of the refrigerant; subcooling refrigerant after exiting the pressure reduction device in a subcooler; evaporating refrigerant after exiting the subcooler in an evaporator; passing a forced stream of the air against said evaporator wherein it forms a cooled and dehumidified air stream; and passing the cooled and dehumidified air stream against the subcooler wherein it is heated.
