Patent ID: 10330365

Abstract:
A refrigerant circuit forming a refrigeration cycle by connecting together a compressor, an outdoor heat exchanger, an expansion valve, and an indoor heat exchanger via a refrigerant pipe; and a control unit controlling a blown-out air temperature by causing the indoor heat exchanger to exchange heat while controlling the refrigeration cycle based on one of a sensible heat capability and a latent heat capability calculated from a cooling capability of the refrigerant circuit and a cooling load of the refrigerant circuit. The control unit includes: a capability judging unit judging the cooling capability of the refrigerant circuit based on the one of the sensible heat capability and the latent heat capability; and a control selecting unit selecting one from between superheat degree control to control a degree of superheat and evaporating temperature control to control an evaporating temperature, based on a determination result obtained by the capability judging unit.
