Cooling chamber steam compression composite circulating system based on semiconductor super-cooling synergy

Abstract

The invention discloses a cooling chamber steam compression composite circulating system based on semiconductor super-cooling synergy. The cooling chamber steam compression composite circulating system comprises a condenser, wherein a refrigerant at the outlet of the condenser is partitioned into two paths; the refrigerant outlet of a main branch is connected with the inlet of a semiconductor refrigerator cold end; the refrigerant outlet of the semiconductor refrigerator cold end is connected with the inlet of a first capillary tube wound on an air return pipe; the refrigerant outlet of the first capillary tube is connected with the inlet of an evaporator; the refrigerant outlet of the evaporator is connected with the inlet of the compressor after passing through the air return pipe; the refrigerant outlet of the compressor is connected with one inlet of a convergence jet pipe; the refrigerant outlet of a condenser bypass branch is connected with the inlet of a second capillary tube through an electromagnetic valve; a refrigerant at the outlet of the second capillary tube is connected with the other inlet of the convergence jet pipe after passing through the hot end of the semiconductor refrigerator, and enters the condenser after being mixed with the refrigerant at the outlet of the compressor in the convergence jet pipe.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and in particular relates to a vapor compression composite cycle system of a freezer based on semiconductor supercooling efficiency enhancement. Background technique [0002] Vapor compression freezers occupy most of the market share due to their economic reliability, mature technology, long life and easy use. It consists of key components such as compressors, condensers, capillary tubes, and evaporators. The circulation of the freezer is used for heat exchange, and the heat in the freezer is transferred to the air outside the freezer, so as to achieve the purpose of cooling the air and storage in the freezer. With the popularity of freezers, consumers have put forward higher demands on the freezing capacity of freezers. Therefore, how to effectively improve the freezing capacity of the freezer has become one of the current research focuses on improving refrigeration technology. [0003] ...
