Abstract
According to a controller for a cooling system, when an optimum value of a low-pressure side pressure set value corresponding to an operation environmental condition to be generated is registered in a data base 15, the optimum value of the low-pressure side pressure set value is used. In a case where the optimum value of the low-pressure side pressure set value is not registered in the data base 15, when an optimum value of a low-pressure side pressure set value Ps corresponding to an operation environmental condition adjacent to the operation environmental condition to be generated is registered, the optimum value of the low-pressure side pressure set value Ps is used.
Claims5
A controller for a cooling system comprising a low-temperature showcase having a storage room and a refrigerating machine for supplying refrigerant to the low-temperature showcase, comprising:
- a control data generating unit for generating control data for controlling an operation of the refrigerating machine under an operation environmental condition for defining an operation environment of the cooling system;
- and
- a data base constructing unit for registering an optimum value of the control data based on a “good” or “bad” determination result concerning the cooling state of the storage room of the low-temperature showcase which occurs through the operation based on the control data while associating the optimum value with the operation environmental condition, thereby constructing a data base, wherein when an optimum value of the control data corresponding to an operation environmental condition to be generated is registered in the data base, the control data generating unit uses the optimum value of the control data, and when an optimum value of the control data corresponding to an operation environmental condition to be generated is not registered in the data base, the control data generating unit uses an optimum value of the control data registered in association with an operation environmental condition adjacent to the operation environmental condition to be generated.
