Title: REFRIGERATION DEVICE
Abstract:
[Problem] To quickly detect leakage of a heat medium from a condenser or an evaporator with a simple configuration. [Solution] A refrigeration device 1 relating to the present invention is configured by connecting, using a pipe 15, a compressor 11, condenser 12, expansion valve 13, and evaporator 14 such that a heat medium is circulated therein in such order. The refrigeration device 1 is also provided with: pressure detection units 31, 32 that detect pressure of the heat medium circulating in the pipe 15; and a control unit 41 that determines that leakage of the heat medium from the condenser 12 or the evaporator 14 has occurred, in the cases where the values of the pressure detected by the pressure detection units 31, 32 are equal to or lower than a predetermined value.
