Abstract

The invention discloses a refrigerating circulation system and a control method thereof, relates to the field of air conditioner refrigerating systems, and mainly aims at increasing the performance coefficient and improving the reliability of the refrigerating circulation system under the ultralow temperature refrigerating working condition. According to the main technical scheme, the refrigerating circulation system comprises a condenser, an evaporator and a refrigerant pump; a refrigerant outlet of the evaporator is connected with a refrigerant inlet of the condenser; an inflow opening of the refrigerant pump is connected with a refrigerant outlet of the condenser; and an outflow opening of the refrigerant pump is connected with a refrigerant inlet of the evaporator. Compared with the prior art, due to the fact that the power of the refrigerant pump is much lower than that of a compressor and the refrigerant pump can be lubricated without oil, the refrigerant pump has great advantages of the performance coefficient and the reliability under the ultralow temperature refrigerating working condition. Accordingly, the performance coefficient of the refrigerating circulation system adopting the refrigerant pump under the ultralow temperature refrigerating working condition is increased, and the reliability of the refrigerating circulation system adopting the refrigerant pump under the ultralow temperature refrigerating working condition is improved.

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...
