A refrigeration evaporator is a device that removes heat from a refrigerated area or system. They come in a variety of sizes and styles, but all have the same primary purpose: to keep items cold, but without excessive freezing or frost. Refrigerated rooms require temperature control and regular heat transfer cycles.
There are three main types of industrial evaporators: air defrost, ammonia defrost, and electric defrost. The most common type is an air defrost evaporator, which uses air to cool the refrigerant passing through it.
There are also electric defrost evaporators, which use electricity to create a cooling effect. Each type has its advantages and disadvantages, so it's crucial to understand your business needs before purchasing.
Chiller Evaporator Construction
Chiller evaporators are made up of two main components: the condenser and the evaporator coil. The condenser is responsible for cooling the gas or liquid passing through it, while the coil absorbs heat from the object being cooled. Most simpler evaporator coils are made of copper or aluminum.
