AI Technical Summary

Technical Problem

Existing refrigeration equipment is prone to condensation or frosting in low-temperature environments, especially between the evaporator/condenser and the heat exchanger, which affects the refrigeration effect.

Method used

Introducing a liquid receiver into the refrigeration system collects the liquid refrigerant from the evaporator and condenser, increasing the proportion of gaseous refrigerant entering the heat exchanger. Through heat exchanger design optimization, it is ensured that the refrigerant reaches above the ambient temperature within the heat exchanger, reducing the risk of condensation or frost.

Benefits of technology

It effectively reduces the risk of condensation or frosting between the evaporator/condenser and the heat exchanger, and improves the cooling effect and system stability.
