Title:
REFRIGERATION DEVICE
Document Type and Number:
Japanese Patent JP2018091502
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a refrigeration device which suppresses deterioration of reliability in the case of using a refrigerant leakage sensor.SOLUTION: A refrigeration device 100 performs cooling of a utilization side space SP by performing a refrigeration cycle in a refrigerant circuit RC. The refrigeration device 100 includes: a heat source unit 10; a utilization unit 30 having a utilization side heat exchanger 32 arranged in the utilization side space SP; a controller 60 for controlling a state of various devices according to a situation; and a refrigerant leakage sensor 40 arranged in the utilization side space SP and for outputting a refrigerant leakage signal with respect to the controller 60 when a leaked refrigerant is detected. The controller 60 executes refrigerant leakage dealing processing for dealing with refrigerant leakage, when it has received a refrigerant leakage signal. The controller 60 executes mask processing for masking the refrigerant leakage signal, during defrosting processing for defrosting the frost attached to the utilization side heat exchanger 32.SELECTED DRAWING: Figure 3
