Introduction
A desuperheater is alos called as a secondary device of heat exchanger that transfers heat efficiently from the earth in the winter season and from your house in the summer, into your domestic hot water tank.A desuperheater is a device that cools down the superheated refrigerant (gas that is at a temperature above its saturation temperature). The temperature of this gas is reduced by spraying droplets of water into the flow of the superheated gas.
Desuperheaters are the components which is used in the thermal management of heat from power generation sources to industrial uses in Refrigeration and Air Conditioning.
Types of Desuperheater
There are two types of desuperheater
1.Freon Desuperheater
Maniks desuperheater basically works on Freon refrigerant gas to extract the superheated refrigerant and use it for other purposes. Therefore this heat if used for boiling water in hotels, restaurants etc users can get free of cost water.
2.Ammonia Desuperheater
Ammonia is the very old one of all the refrigerants and it is still widely used in the refrigeration and air conditioning applications.
Desuperheater Desing
basic desuperheater design includes the Double Walled ” Tube in Tube “, vented, counter flow heat exchanger. Vent tube is including serrations on inner & outer surfaces to avoid cross contamination of refrigerant and water/ fluid. Each tube has a tube inside that gives permission to water/ fluid to travel in an opposite direction.

Installation of Desuperheater
Before the condenser and the oil separator the Desuperheater Water Heater is installed The refrigerant travels through the series of tubes in the Desuperheater before entering the condenser. Normally the Desuperheater Water heater is designed considering the hot water requirement for the processes. When needs of hot water & refrigeration are not simultaneous, a ” Recirculation ” type system is provided wherein hot water is generated, stored & maintained in an insulated tank. This hot water then can be utilised as and when required.
Maniks is the most reputed Indian brand with a history of 30 years for manufacturing valves and other devices used in applications of Refrigeration and Air Conditioning.
Desuperheaters are important thing used in the management of superheated gas from power generation sources to industrial uses of gas. This process of desuperheating the refrigerant represents the vast majority of desuperheating applications. In water spray desuperheater, superheated refrigerant is get transfered from a section of pipe fitted with one or more spray nozzles. These nozzles inject a small amount fine spray of cooling water onto the superheated refrigerant, which causes the water to be converted into gas, hence reducing the quantity of superheat.
