Abstract

The object of the present invention is to provide a semi-full liquid carbon dioxide refrigeration system which is environment-friendly, energy-saving and can cool down the temperature evenly in the storage. The technical solution adopted by the present invention is a semi-full liquid carbon dioxide refrigeration system, including a high-temperature refrigeration part using R134a as a refrigerant and a low-temperature refrigeration part using carbon dioxide as a refrigerant. The high-temperature refrigeration part and the low-temperature refrigeration part Connected by evaporative condenser. The refrigeration system can meet various low-temperature freezers and quick-freezers such as medicine storage, meat processing storage and frozen food storage.

Description

technical field [0001] The invention belongs to the technical field of refrigeration systems, in particular to a semi-full liquid carbon dioxide refrigeration system. Background technique [0002] At present, in the refrigeration system using carbon dioxide as the refrigerant, it is mostly used for cascading with ammonia as the refrigerant, and the refrigeration system is mostly in the form of dry evaporation. Due to the physical properties of ammonia, there is a greater safety hazard when used as a refrigerant, and the dry evaporation refrigeration system is prone to uneven temperature in the warehouse, and the heat transfer efficiency is not as high as that of the flooded system. Contents of the invention [0003] In order to overcome the defects of the prior art, the present invention aims to provide a semi-full liquid carbon dioxide refrigeration system that is environmentally friendly, energy-saving, and can cool down the storage evenly. [0004] The technical soluti...
