Abstract

The invention relates to a cooling system, a control device and a control program. The cooling system is provided in which an integrated controller (10) controls the compressor for compressing a refrigerant and at least one constituent device which is a separate device from the compressor and that constitutes a refrigerant circulation circuit together with the compressor. The integrated controller has a control data generation unit (16) that controls the compressor using a compressor sensor for detecting a first physical value, which is a physical value of the refrigerant at the time of normal operations, and an abnormality detection unit (13) for detecting an abnormality of the compressor sensor. The control data generation unit controls the compressor using a constituent device sensor for detecting a second physical value that is a physical value having a close correlation with the first physical value in place of the compressor sensor when the abnormality was detected by the abnormality detection unit.

Description

technical field [0001] The present invention relates to a cooling system, a control device, and a control program that use a compressor that compresses a refrigerant, and components that constitute a refrigerant circulation circuit together with the compressor as devices different from the compressor. . Background technique [0002] Conventionally, as a cooling system using a refrigerant circulation circuit that circulates a refrigerant, an air-conditioning system that air-conditions indoor spaces such as stores, and a refrigeration system that refrigerates / freezes products in showcases installed in stores and the like have been widely used. / freezing system. [0003] The refrigerant circulation circuit used in such a cooling system includes: a compressor for compressing refrigerant; and a constituent device which is different from the compressor and constitutes the refrigerant circulation circuit together with the compressor. Here, the constituent equipment is, for examp...
