Embodiment Construction

[0028] Embodiments of the present invention will be described below with reference to the drawings.

[0029] figure 1 It is a schematic diagram showing the structure of the cooling system 1 according to the embodiment of the present invention.

[0030] As shown in the figure, the configuration 1 of the cooling system includes: a plurality of low-temperature display cabinets 7 are connected in parallel to the cabinet system refrigerator 3 through the refrigerant pipe 5a as the liquid pipeline and the refrigerant pipe 5b as the gas pipeline. The refrigeration circuit 2, the main controller (main control device) 4 and the compressor controller (compressor control device) 6.

[0031] The rack system refrigerator 3 includes a plurality of compressors 9 , a condenser 11 , a condenser fan 13 , and a low-pressure side pressure sensor 26 for detecting the refrigerant pressure on the low-pressure side (and referred to as “low-pressure side pressure”). Each of the compressors 9 is a fi...

Abstract

The invention provides a cooling system which has a plurality of kinds of compressors capable of being selected and combined freely, and can keep the cooling performance of low temperature showcase and improve energy saving performance of the refrigerator. The cooling system comprises: a refrigeration loop composed by connecting a plurality of low temperature showcases in parallel by refrigerant pipes and cabinet system refrigerators selected and combined freely from the plurality of kinds of compressors; a main controller for setting the low pressure side pressure set value of the cabinet system refrigerators according to the cooling state of the low temperature showcase; and a compressor controller capable of acquiring the control setting needed in the capacity control in the assembling of the compressors in the cabinet system refrigerators, receiving the low pressure side pressure set value from the main controller, and controlling the capacities of the compressors according to the low pressure value corresponding to the low pressure side pressure set value and the control setting.

Description

technical field [0001] The present invention relates to a cooling system composed of a low-temperature display cabinet installed in a supermarket, etc., and a refrigerator that supplies refrigerant to the low-temperature display cabinet, and particularly relates to a refrigeration system with arbitrarily selected and freely combined compressors from a variety of compressors. Machine cooling system control technology. Background technique [0002] Conventionally, a known cooling system is constituted by connecting a plurality of low-temperature showcases such as freezing and refrigerating showcases in parallel with a refrigerator through refrigerant pipes. Related low-temperature display cabinets are provided with multiple sets in stores such as supermarkets, for displaying and selling frozen or refrigerated foods. [0003] The above-mentioned refrigerator is generally constituted by housing one or more compressors inside it and a microcomputer controlling the compressors in...
