Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/205535
Kind Code:
A1
Abstract:
A refrigeration cycle device (1) comprises a plurality of refrigeration cycle units (200-1 to 200-n) each of which has a mutually independent refrigerant circuit that uses a refrigerant, the refrigeration cycle units (200-1 to 200-n) being positioned in a circulation path of a shared heat medium and controlling the temperature of the heat medium. A control device (100) sets the number of operating units to an initial number of operating units at a first time at which the refrigeration cycle device (1) has started a cooling operation. The control device (100) determines an intermediate target change amount for the temperature of the heat medium at a second time on the basis of the difference between the temperature of the heat medium at the first time and a target temperature. The control device (100) adjusts the number of operating units among the plurality of refrigeration cycle units in accordance with the difference between the intermediate target change amount and a temperature change amount of the heat medium arising from the first time to the second time so that the temperature of the heat medium at a third time approaches the target temperature.
