Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/012600
Kind Code:
A1
Abstract:
This refrigeration cycle device has a refrigerant circuit in which a compressor that compresses a refrigerant that was taken in and delivers same, a condenser that condenses the refrigerant by causing heat dissipation in the refrigerant, a plurality of throttling devices that reduce the pressure of the condensed refrigerant, and a plurality of evaporators that evaporate the refrigerant by causing the refrigerant to absorb heat are connected with piping, wherein a plurality of sets each constituted by a throttling device and an evaporator in serial connection are arranged in parallel. The refrigeration cycle device comprises a plurality of temperature detection devices that detect the evaporation temperature of each evaporator, and a control device that controls the compressor and the throttling devices on the basis of the evaporation temperatures of the evaporators that are each detected by the plurality of temperature detection devices.
