Abstract:
A freezer device (1000) comprises: a refrigerant circuit (300) configured so as to circulate a refrigerant and such that a compressor (1), a condenser (2), an expansion device (3), and an evaporator (4) are connected in that order; a pressure sensor (6) that measures the pressure of the refrigerant on the refrigerant intake side of the compressor (1); and a control device (10) that controls the refrigerant circuit (300). When the value measured by the pressure sensor (6) during driving of the compressor (1) falls below a cut OFF value, the control device (10) stops the compressor (1), and when an update condition is established, the control device (10) updates the cut OFF value.
