AI Technical Summary

Technical Problem

In the existing refrigeration system, the liquid output temperature of the condenser is relatively high, which affects the system's supercooling and energy efficiency. At the same time, the intake overheat is insufficient, which may lead to compressor liquid strike.

Method used

A refrigeration system is designed, by setting a second heat exchange chamber in the condenser and connecting the condenser and the second heat exchange chamber through the first and second pipelines respectively, the refrigerant is throttled by using the throttling assembly to realize the refrigerant dual heat exchange and flow control.

Benefits of technology

It effectively reduces the liquid discharge temperature of the condenser, improves the supercooling and energy efficiency of the refrigeration system, increases the suction overheating, prevents compressor liquid strikes, and achieves better refrigerant distribution and temperature control.
