Abstract
A refrigerant circuit includes a heat source unit including a compression element and a radiator and a plurality of cooling units each including an evaporator and performing or stopping cooling operation depending on a difference between a temperature of a target to be cooled and a set temperature. A control unit outputs information indicative of a capacity required of the heat source unit on the basis of first information that is usable for deriving a cooling capacity required of each of the plurality of cooling units and second information indicative of the temperature of the target to be cooled and the set temperature in each of the plurality of cooling units.
Claims20
A control system applied to a refrigeration apparatus, the control system comprising:
- circuitry configured to
- control the refrigeration apparatus, the refrigeration apparatus including a refrigerant circuit that includes a heat source having a compression element that at least includes a compressor and a radiator and a plurality of cooling units each including an evaporator and perform or stop a cooling operation depending on a difference between a temperature of a target to be cooled and a set temperature, the refrigeration apparatus performs a refrigeration cycle by circulation of a refrigerant through the refrigerant circuit, and
- output information indicative of a capacity required of the heat source on a basis of first information that is usable for deriving a cooling capacity required of each of the plurality of cooling units and second information indicative of the temperature of the target to be cooled and the set temperature in each of the plurality of cooling units.
A refrigeration system comprising:
- a refrigeration apparatus including a refrigerant circuit that includes a heat source having a compression element that at least includes a compressor and a radiator and a plurality of cooling units each including an evaporator and perform or stop a cooling operation depending on a difference between a temperature of a target to be cooled and a set temperature, the refrigeration apparatus performs a refrigeration cycle by circulation of a refrigerant through the refrigerant circuit;
- and
- a control system including circuitry configured to control the refrigeration apparatus and output information indicative of a capacity required of the heat source on a basis of first information that is usable for deriving a cooling capacity required of each of the plurality of cooling units and second information indicative of the temperature of the target to be cooled and the set temperature in each of the plurality of cooling units, wherein
- the heat source operates on a basis of the information indicative of the capacity required of the heat source.
A non-transitory computer readable storage medium having code stored therein that when executed by circuitry cause the circuitry to perform a control method on a refrigeration apparatus, the control method comprising:
- controlling the refrigeration apparatus, the refrigeration apparatus including a refrigerant circuit that includes a heat source having a compression element that at least includes a compressor and a radiator and a plurality of cooling units each including an evaporator and perform or stop a cooling operation depending on a difference between a temperature of a target to be cooled and a set temperature, the refrigeration apparatus performs a refrigeration cycle by circulation of a refrigerant through the refrigerant circuit, and
- outputting information indicative of a capacity required of the heat source on a basis of first information that is usable for deriving a cooling capacity required of each of the plurality of cooling units and second information indicative of the temperature of the target to be cooled and the set temperature in each of the plurality of cooling units.
