Title:
REFRIGERATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/074452
Kind Code:
A1
Abstract:
Provided is a refrigerating device that ensures safety while inhibiting cost increases. A refrigerating device (100), which performs a refrigeration cycle in a refrigerant circuit (RC) that includes a compressor (11), a heat source-side heat exchanger (12), and a use-side heat exchanger (33), comprises a use-side fan (37) that generates an air flow, and a controller (50). The use-side fan (37) is disposed in a target space (SP) inside of which air is to be cooled. The controller (50) executes a refrigerant leak determination process and determines whether a refrigerant leak has occurred on the basis of the refrigerant state in the refrigerant circuit (RC). When a determination that a refrigerant leak has occurred has been made by the refrigerant leak determination process, the controller (50) executes agitation control of leaked refrigerant and operates the use-side fan (37) so as to prohibit the occurrence of local areas in which the concentration of the leaked refrigerant is large in the target space (SP).
