Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/061010
Kind Code:
A1
Abstract:
A control device with which a refrigeration cycle device according to the present invention is provided performs a refrigerant recovery operation when an operation mode is switched from a defrosting mode to a heating mode. The control device is configured such that, during the refrigerant recovery operation, by rotating a fan of a blower while monitoring the pressure (Pout) on the discharge side (high pressure side) of a compressor, feedback control (S34, S35) is performed so as to bring the high pressure-side pressure (Pout) closer to a high pressure-side target pressure value (P2). During the refrigerant recovery operation, the control device performs feedback control (S32, S33) so as to bring the low pressure-side pressure (Pin) closer to a low pressure-side target pressure value (P1) by controlling the drive frequency of the compressor while monitoring the pressure (Pin) on the intake side (low pressure side) of the compressor.
