AI Technical Summary

Technical Problem

The existing refrigeration system cannot adjust the refrigerant flow under different operating modes, resulting in high energy consumption and waste of cooling capacity and noise during the defrosting process.

Method used

Design a multi-mode refrigeration system that employs a three-way reversing valve and a refrigerant dynamic buffer unit. The system switches refrigerant flow channels and regulates refrigerant circulation volume through a controller. Combined with a liquid receiver and an electric valve, it achieves adaptive adjustment of refrigerant circulation volume and optimizes the throttling device and defrosting process.

Benefits of technology

It improves refrigeration efficiency, reduces energy consumption, shortens defrosting cycles, eliminates defrosting noise, and enhances the system's energy efficiency ratio and thermal efficiency.
