Abstract

The invention provides a refrigerating system and a control method thereof. The refrigerating system involves a cold storage pool, a heat exchange assembly and a controller, wherein a first water inlet of the heat exchange assembly communicates with a water outlet of the cold storage pool through a first flow path, a water outlet of the heat exchange assembly communicates with a water inlet of thecold storage pool through a second flow path, and a temperature sensor for detecting the water temperature in the second flow path is arranged on the second flow path; the first flow path comprises at least two branches connected in parallel, a water pump is arranged on the at least one branch, and an electromagnetic valve is arranged on the at least one branch; and the controller is connected with the water pump, the temperature sensor and the electromagnetic valve. According to the refrigerating system, the controller increases or decreases the opening degree of the electromagnetic valve according to a temperature value sent by the temperature sensor, so that the flow of water entering the heat exchange assembly is decreased, the heat exchange amount of the heat exchange assembly is further decreased, and the refrigerating capacity of the refrigerating system is controllable.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigeration system and a control method thereof. Background technique [0002] Cold storage air-conditioning systems usually include three cooling modes: cold storage pool cooling, refrigeration host cooling, and cold storage pool and refrigeration host combined cooling. The air conditioning system can switch between these three cooling modes according to the cooling cost. For example, the electricity price is higher during the day When the cold storage pool is used for cooling, and when the electricity price is low at night, the refrigeration host is used for cooling, and the water in the cold storage pool is cooled for use, so as to reduce the operating cost of the refrigeration system. In practical applications, when the cold storage pool is used for cooling, the cooling capacity of the cold storage pool has been adjusted to the minimum, but the cooling supply still ...
