Desuperheater water heater


New member
Hi Everyone,
A ]desuperheater is known as a secondary heat exchanger device that transfers heat efficiently from the earth in the winter season and from your house in the summer, into your domestic hot water tank.
Desuperheaters are crucial components used in the thermal management of heat from power generation sources to industrial uses in Refrigeration and Air Conditioning.
When gas is used for heating or other heat transfer or in industrial processes, it is most efficient when saturated. It is a device that lowers the temperature of superheated gas so that it can be used efficiently for heating or for other industrial use. This gas temperature minimization is also called as attemperation, is performed by the desuperheater water heater (a device that injects a prescribed amount of water into a gas flow stream).
The general purpose, of this device is to provide effective and continuous heat transfer between gas and water. And a highly effective desuperheater application and design ensures that costly problems to be avoided, including general wear of downstream piping and equipment, long startup and shutdown times, and reduced process efficiency.
Desuperheater Working Principle/ Function:
The primary function of a desuperheater water heater is to minimize the temperature of superheated gas and other vapors. This temperature reduction is achieved by the process vapor being brought into direct contact with a liquid such as water. The injected water is then evaporated.
Desuperheater Design:
Double Walled “Tube in Tube “, vented, counter flow heat exchanger. Vent tube having serrations on inner & outer surfaces to avoid cross contamination of refrigerant and water/ fluid. Each tube has a tube inside that allows water/ fluid to travel in an opposite direction.
Desuperheater Installation:
The Maniks Desuperheater Water Heater is placed before the condenser and the oil separator. The ammonia refrigerant travels through the different tubes in the to lower the refrigerant temperature before entering the condenser. The Water heater is manufactured considering the hot water requirements for industrial processes. When the needs of refrigeration and hot water are not simultaneous, a “Recirculation” type system is provided in which hot water is generated, stored & maintained in a separate insulated tank. This stored hot water then can be utilized as and when required for future use.

My Question is can we use this for van engine cooling system?

Any advice appreciated?
