What is Desuperheater | Water heater and its Applications? Maniks Desuperheater | Page 2

Working of Desuperheater:
In a usual AC & R system, the refrigerant temperature rises in tune of 80℃ to 120℃
after compression. The refrigerant is further put to the air/ water cooled condenser to
condense near about 40℃.
While the condensing of refrigerant in the condenser, the total heat contained in this high
Temperature/high pressure gas gets wasted to the atmosphere.
This superheat of the gas which is part of the total heat content of the gas, has a
substantial heat potential provided the same is reclaimed efficiently and is optimized for
energy saving
Maniks Desuperheater Water Heater is the ultimate accessory for an AC & R plant that
can be used to remove superheat of the refrigerant.
Desuperheater Design:
Double Walled “Tube in Tube ", vented, counter flow heat exchanger. Vent tube have serrations
on outer & inner surfaces to avoid cross contamination of water/ fluid and refrigerant. Each and
every tube has a tube inside it that allows water/ fluid to travel in an opposite direction.
The Desuperheater Water Heater is actually installed before the oil separator and the condenser.
The refrigerant gas travels through the series of different tubes in the Desuperheater device
before it enters the condenser. Normally the Desuperheater Water heater is manufactured
considering the hot/warm water requirement for the processes. When needs of refrigeration &
hot water are not simultaneous, a " Recirculation " type system is provided where hot water is
generated, stored & maintained in an insulated tank. The hot water generated then can be utilized
as and when required by the customers.
