Abstract (en)

An air conditioner 1 includes an outdoor unit 2 which includes a compressor 10 and an outdoor heat exchanger 13 and a water temperature control unit 40 which includes a water heat exchanger 51 connected to the outdoor unit 2 through a unit connection pipe 6, the water heat exchanger 51 exchanging heat between water and a refrigerant supplied from the outdoor unit 2 and further includes a low-pressure sensor 42 which detects a low pressure of a refrigerant at a suction side of the compressor 10 and a freezing determination unit which determines whether water flowing through the water heat exchanger 51 is going to be frozen when the low pressure is lower than a predetermined low-pressure protection value, the low-pressure protection value set in consideration of pressure loss generated when a refrigerant flows through the unit connection pipe 6.
