Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/235230
Kind Code:
A1
Abstract:
This refrigeration cycle device has a refrigerant circuit in which a compressor, a condenser, a throttling device, and an evaporator are connected by piping and that causes a refrigerant to be circulated, and the device performs an operation by being supplied with direct current power. The refrigeration cycle device comprises: a compressor inverter device that converts direct current to alternating current and supplies power to a compressor motor; a fan motor inverter device that converts direct current to alternating current and supplies power to a fan motor; a voltage detection device that detects the voltage of the direct current to be applied; and a control device that performs a process to determine the upper limit for the output drive frequency of at least one of the compressor inverter device and the fan motor inverter device on the basis of the voltage related to the detection by the voltage detection device.
