AI Technical Summary

Technical Problem

Existing cold storage refrigeration units suffer from heat waste or low heat recovery efficiency, making it impossible to achieve full heat recovery and utilization.

Method used

The system employs a combination design of a total heat recovery condenser, an insulated hot water storage tank, a liquid storage tank, a subcooling economizer, and a throttling valve to form a highly efficient refrigeration cycle. This allows the heat absorbed by the evaporator to be directly transferred to the hot water storage tank through the total heat recovery condenser, generating hot water available to users.

Benefits of technology

It achieves full recovery and utilization of heat during the cold storage refrigeration process, reduces production energy consumption, simplifies equipment structure, improves the practicality and economy of the equipment, and meets the dual needs of cold storage refrigeration and hot water supply.

Abstract

This utility model discloses a cold storage refrigeration unit with high-efficiency heat recovery function, belonging to the field of cold storage refrigeration equipment. The unit includes an evaporator, a compressor, a total heat recovery condenser, an insulated hot water storage tank, a liquid storage tank, a subcooling economizer, and a throttling valve. The evaporator outlet is connected to the compressor inlet, and the compressor outlet is connected to the total heat recovery condenser inlet. The total heat recovery condenser outlet is connected to the evaporator inlet sequentially via the liquid storage tank, the subcooling economizer, and the throttling valve, forming a refrigeration cycle loop. The total heat recovery condenser and the insulated hot water storage tank are connected by pipelines to form a water circulation path. The insulated hot water storage tank has a lower cold water inlet and an upper hot water outlet. It can meet the refrigeration needs of cold storage while recovering all usable heat (excluding natural losses) through the total heat recovery condenser to produce hot water, eliminating the need for secondary heat dissipation in conventional condensers. This solves the problems of heat waste or low heat recovery efficiency in conventional equipment, resulting in high heat recovery efficiency and significant energy savings.
