Abstract

The invention relates to a refrigeration cycle system and a control method thereof, and relates to the field of air-conditioning and refrigeration systems. The main purpose is to improve the performance coefficient and reliability of the refrigeration cycle system under ultra-low temperature refrigeration conditions. The technical solution mainly adopted is: a refrigeration cycle system, including a condenser, an evaporator and a refrigerant pump, the refrigerant outlet of the evaporator is connected to the refrigerant inlet of the condenser, and the inlet of the refrigerant pump is connected to the condenser The outlet of the refrigerant pump is connected to the refrigerant outlet of the evaporator, and the outlet of the refrigerant pump is connected to the refrigerant inlet of the evaporator. Compared with the existing technology, since the power of the refrigerant pump is much smaller than that of the compressor, and it can be lubricated without oil, the coefficient of performance and reliability of the refrigerant pump operation under ultra-low temperature refrigeration conditions have greater advantages, thereby improving The coefficient of performance and reliability of the refrigeration cycle system using refrigerant pumps under ultra-low temperature refrigeration conditions were studied.

Description

technical field [0001] The invention relates to the technical field of air conditioning and refrigeration systems, in particular to a refrigeration cycle system and a control method thereof. Background technique [0002] The existing refrigeration cycle is based on the work of the compressor, and the dynamic balance and refrigeration cycle of the refrigeration system are achieved through the compressor. However, under ultra-low temperature refrigeration conditions, when the natural environment temperature is low, the refrigeration cycle system using a compressor consumes more energy, its energy efficiency is relatively limited, and the control is more complicated, and the maintenance and use costs are higher. Contents of the invention [0003] In view of this, the present invention provides a refrigeration cycle system and its control method, the main purpose of which is to improve the coefficient of performance and reliability of the refrigeration cycle system under ultra...
