Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/111560
Kind Code:
A1
Abstract:
This refrigeration cycle device (1) comprises: a plurality of evaporators (51, 52); at least one image-capturing device (61, 62) for capturing images of the plurality of evaporators (51, 52); and a control device (100) which executes, on the basis of the images captured by said at least one image-capturing device (61, 62), a defrosting operation of an evaporator, in which the frosting amount exceeds a determination value, among the plurality of evaporators (51, 52). Preferably, the control device (100) is configured to perform a defrosting operation of one evaporator among the plurality of evaporators (51, 52). The control device (100) determines the execution order of the defrosting operation of the plurality of evaporators, on the basis of the captured images.
