Abstract

The invention provides a refrigeration system and its control method. The refrigeration system includes: a compressor, a condenser, a refrigeration evaporator, a refrigeration evaporator, and a first pipeline and a second pipeline. One end of the first pipeline communicates with the condenser , the other end communicates with the low-pressure suction port, one end of the second pipeline communicates with the condenser, and the other end communicates with the medium-pressure suction port, and the first throttling device is arranged upstream of the refrigeration evaporator on the first pipeline, A second throttling device is also arranged on the second pipeline upstream of the refrigerating evaporator. According to the present invention, it is possible to simultaneously realize refrigeration, refrigeration and freezing at two different evaporation temperatures in the same refrigeration system. After the evaporation of the application is completed, the suction superheat of the compressor is greatly reduced, the discharge temperature is reduced, and the power consumption of the compressor is reduced. , At the same time, due to the heat exchange in the latent heat state, its cooling capacity is greatly increased, which can effectively meet the cooling capacity for refrigeration.

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] The existing conventional refrigeration unit has a single function, has its specific operating temperature range, and also has specific operating conditions during use. Different models are used to meet different working temperature temperatures. When it comes to simultaneous refrigeration and refrigeration needs, it is necessary to Equipped with specific refrigerating and freezing units. When the conventional refrigeration unit is used in refrigeration and refrigeration, the refrigerant in the system will be throttled to a very low pressure, and it will first pass through the heat exchanger for refrigeration to exchange heat and become a relatively superheated gas. The refrigerant then flows through the heat exchanger for refrigeration to exchange heat, and the refrigerant coming out of the...
