FIGURE: TYPICAL REFRIGERATION CYCLE
The basic principle of heat recovery in a refrigeration and Air Conditioning
cycle is shown in fig. In figure, it is seen that the discharge gas coming from
the compressor is in a superheated (high temperature) state. So this excess
heat can be extracted by desuperheating it before it enters the condenser so
as to improve its efficiency and life. Because of this, Desuperheater is
located between compressor and condenser as it minimizes the temperature
of superheated refrigerant. The discharge temperatures of gas in most of the
air cooling systems are quite high (in the range of 70°C to 100°C). Hence
the superheated refrigerant can be used to heat the water to about 60°C
and the amount of heat recovered by desuperheater would be of 16% to
20% of the total heat rejected by the condenser.

Maniks Desuperheater Types:
1) Ammonia Desuperheater
2) Freon Desuperheater
1) Ammonia Desuperheater:
Ammonia is one of the most trusted refrigerants from the 19th century; as it
is used commercially in large freezing and refrigeration plants, food
preservation and industrial process plants. Ammonia is a well-known
refrigerant because it is cost effective, more efficient refrigerant gas as it
utilizes less electricity, ultimately resulting in lower operating costs and
naturally available and a long-term alternative for industrial refrigeration.
Maniks is a leading manufacturer of ammonia desuperheater that enables
energy-efficient and safe application of ammonia refrigeration.
