What is Desuperheater | Water heater and its Applications? Maniks Desuperheater a High Performance Energy Sav | Page 3

2) Freon Desuperheater:
Freon is also known as Hydro-fluoro-carbons – HFC. It is the most used
refrigerant today. Maniks has a rich experience in designing and
manufacturing of refrigeration systems with Freon, having hundreds of
refrigeration and air cooling systems working in different economic sectors
such as the refrigerating and freezing industries. Maniks Freon
desuperheater are relatively low investment cost, doesn’t require any special
means of protection while operating, Easy to run and maintain, Easier repair
in case of failure
Desuperheater Design:
Maniks Desuperheater is Double Walled “Tube in Tube", counter flow, vented
heat exchanger device. Vent tube have serrations on inner & outer surfaces,
to avoid cross-contamination of refrigerant (i.e. ammonia or Freon) and
water. Each tube has a tube inside that allows water to travel in a reverse
direction. When the refrigerant travels from compressor to condenser the
desuperheater comes into picture. The superheated refrigerant is cooled
down by spraying the droplets of water on this refrigerant and then it is
passed on to the condenser.
Desuperheater Working:
The Desuperheater Water Heater is installed in between the condenser and
the compressor. The ammonia or Freon refrigerant gas travels through the
number of series of tubes in the Desuperheater before entering the
condenser. Normally the Desuperheater Water heater is designed
considering the hot water requirement in Hotels and to recover heat which is
otherwise get wasted in the environment. When needs of refrigeration and
hot water are not simultaneous, a " Recirculation " type system is provided,
where hot water is generated, stored & maintained in an separate tank.
Hence this hot water then can be used as and when required. The
Desuperheater water heater can be easily retrofitted on scroll, reciprocating,
or screw type chillers.
Desuperheater Function:
Desuperheater water heater is used to take out the excess heat from
superheated gas (Ammonia or Freon) for the use of boiling water at home,
hotels and many such areas.
