In a cooling bike of a refrigeration system, warmth is absorbed by the vapor refrigerant in the evaporator adhered to by the compression that the refrigerant by the compressor. The high pressure and high temperature state of the vapor refrigerant is then converted to liquid at the cond. It is designed to condense efficiently the compressed refrigerant vapor.
You are watching: What is the purpose of the condenser
There room basically three species of condensing unit depending upon how the warmth is removed by the condensing tool which is normally water, wait or a combination of both.Air-Cooled types room usually supplied in the residential and tiny offices applications. Castle are used in small capacity systems listed below 20 tons. The advantages of making use of this architecture include not having actually to perform water piping, not vital to have water handle system, saving in water costs and also not lot scaling problems caused by the mineral content of the water. It is also easier to install and also has lower initial cost. There isn"t much maintenance problems.The disadvantages room that that requires greater power per ton that refrigeration, has much shorter compressor life and on job when most cooling is required, the the very least is available.
The circulation the air-cooled type can be by natural convection or by required convection (usually making use of blower or fan). Because of its minimal capacity, natural convection is used in smaller applications such as freezers and also refrigerators. In required convection, wait is circulated by making use of a pan or blower that pulls the atmospheric air v the finned coils. Internally, the refrigerant circulates through the coil and also air flows throughout the exterior of the tubes.Water-Cooled There are 3 varieties commonly being used. They are shell and also tube, shell and also coil, and twin tube. The most frequently used is the shell and tube type and are usually easily accessible from two tons up to pair of hundreds tons. This design has lower power needs per ton of refrigeration and the compressors can last longer compared to the air-cooled type. A water cooling tower is commonly used for greater capacity application.Evaporative type i m sorry is a combination of water and also air-cooled.
Air-Cooled and also Water-Cooled comparison Summary
Air-cooled type operates at higher head pressure or condensing pressure, hence reducing the capacity of the compressor and also increases the power intake. In general, a 2 hp water-cooled mechanism will require the very same refrigeration together a 3 hp air-cooled system.

The maintenance prices of water-cooled type is around three to 4 times the air-cooled type. Air-cooled kind maintenance is usually restricted to regular lubrication the fan and motor bearings. Water-cooled form requires clean from algae and also bacteria. Scale on the tubes are removed by utilizing acid compound. Proper water therapy is also crucial to the operation of the cond.
