injects moisture through small holes into the path of high-velocity steam.
After injection, the water is atomized into small drops and quickly
evaporated by absorbing the superheat. Measurement of the steam
temperature downstream is used to control the amount of water added
during desuperheating.
Steam Desuperheater is used to spray water into steam so that water
gets mixed with steam resulting in reduction in the temperature of the
outlet steam. It can be classified into two
1. Integral type- Desuperheater is in-built with actuator so that
there is no need to separate spray water valve
2. Non Integral type- Desuperheater nozzle and water valve are
separate units

Need of Desuperheater in Refrigeration
The basic principle of refrigeration is the evaporator transfers heat into
the refrigerant the refrigerant transfer heat to the condenser then the
condenser transfers heat to a cooling medium like water or outside air .
The ultimate heat energy emitted from the refrigerators is wasted when it is
transferred to the outside air this waste of energy is been avoided by using
desuperheater.
Desuperheater absorbs the energy from condenser to utilize the same for
other applications.
Working of a Desuperheater
Desuperheater brings superheated steam into direct contact with water
the steam is cooled through the evaporation it reduces the
temperature of the steam.
Maniks desuperheater is designed to work in a refrigeration system so
it uses ammonia water inside to cool the refrigerant gas. When
