AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/234994
Kind Code:
A1
Abstract:
An air conditioning device is provided with: a plurality of heat source machines each having a compressor, a heat-source-side heat exchanger, a flow-regulating valve, and an accumulator; a use-side load connected to the heat source machines by piping and having a use-side heat exchanger for exchanging heat between a refrigerant supplied from the heat source machines and a use-side heat medium; and a control unit for controlling the action of the heat source machines. The control unit has: determination means for determining a state of being in non-normal operation, in which behavior is exhibited that is different from when the heat source machines and the use-side load perform a heating operation or a cooling operation; and equalization means for equalizing the liquid refrigerant flowing to the plurality of heat source machines when a state of being in non-normal operation is determined by the determination means.
