Introduction to Types of Condensers in Cold Storage

Among cold storage equipment, the condenser is one of the main heat exchange equipment in the refrigeration system of cold storage projects.

Its function is to cool and condense the high-temperature refrigerant superheated vapor discharged from the compressor installed in the prefabricated cold storage into a high-pressure liquid. The heat released by the refrigerant in the condenser is taken away by the cooling medium. According to the cooling medium, the condensers installed in prefabricated cold storage projects are mainly divided into air-cooled type and water-cooled type.

Shell and tube condensers for cold storage
The shell and tube condensers installed in cold storage are divided into vertical and horizontal types. Vertical shell and tube condenser. Both ends of the cylinder are welded with perforated tube sheets, and there are corresponding heat transfer tubes in the holes for cooling the refrigerant. Its characteristics are large structure and high material consumption; the cooling water flow rate is low, it is easy to scale, and the cooling water consumption is large. It is suitable for areas with sufficient water sources and poor water quality.
The structure of the horizontal shell and tube condenser is similar to that of the vertical one. When the refrigerant is ammonia, seamless steel pipes are used for the heat transfer tubes, and when the refrigerant is Freon, low-rib copper pipes are used for the heat transfer tubes. The horizontal shell and tube condenser has a relatively high heat transfer coefficient and less cooling water consumption, but it has higher requirements for water quality.

It is widely used in ammonia and Freon refrigeration systems for large, medium and small cold storages.

Air-cooled condensers for cold storage
An air-cooled condenser means that the heat released by the refrigerant is taken away by the air. It is suitable for small cooling loads and is only used in small cold storage refrigeration systems.
