Operate of Condenser

In a cooling cycle of a refrigeration system, warmth is absorbed by the vapor refrigerant within the evaporator adopted by the compression of the refrigerant by the compressor. The excessive stress and excessive temperature state of the vapor refrigerant is then transformed to liquid on the cond. It’s designed to condense successfully the compressed refrigerant vapor.

There are mainly three forms of condensing unit relying on how the warmth is eliminated by the condensing medium which is normally water, air or a mixture of each.

• Air-Cooled sorts are normally used within the residential and small workplaces purposes. They’re utilized in small capability programs beneath 20 tons. The benefits of utilizing this design embody not having to do water piping, not essential to have water disposal system, saving in water prices and never a lot scaling issues attributable to the mineral content material of the water. It is usually simpler to put in and has decrease preliminary value. There is not a lot upkeep issues.The disadvantages are that it requires increased energy per ton of refrigeration, has shorter compressor life and on days when most cooling is required, the least is accessible. 

Although aesthetically not nice, many installers use aluminium duct to redirect the new air away from the condenser.

• The circulation of air-cooled sort might be by pure convection or by compelled convection (normally utilizing blower or fan). Because of its restricted capability, pure convection is utilized in smaller purposes reminiscent of freezers and fridges. In compelled convection, air is circulated through the use of a fan or blower that pulls the atmospheric air by way of the finned coils. Internally, the refrigerant circulates by way of the coil and air flows throughout the skin of the tubes.

• Water-Cooled There are 3 sorts generally getting used. They’re shell and tube, shell and coil, and double tube. Probably the most generally used is the shell and tube sort and are normally obtainable from two tons as much as couple of hundred tons. This design has decrease energy necessities per ton of refrigeration and the compressors can last more in comparison with the air-cooled sort. A water cooling tower is regularly used for increased capability utility.

• Evaporative sort which is a mixture of water and air-cooled.

Air-Cooled and Water-Cooled Comparability Abstract

• Air-cooled sort operates at increased head stress or condensing stress, therefore decreasing the capability of the compressor and will increase the facility consumption. Normally, a 2 hp water-cooled system would require the identical refrigeration as a 3 hp air-cooled system.

• The upkeep prices of water-cooled sort is about three to 4 instances the air-cooled sort. Air-cooled sort upkeep is normally restricted to common lubrication of fan and motor bearings. Water-cooled sort requires cleansing from algae and micro organism. Scales on the tubes are eliminated through the use of acid compound. Correct water remedy can also be essential to the operation of the cond.
