Basic structure of industrial water chiller:

Industrial water chiller consists of
compressor, condenser, evaporator, expansion valve and other accessories.

1. Compressor: in the industrial water chiller
system, the compressor is the power to ensure refrigeration. The compressor is
used to increase the pressure of the refrigerant in the system and make the
refrigerant circulate in the refrigeration system to achieve the purpose of
refrigeration.

2. Condenser: high temperature and high
pressure Freon of the refrigeration system enters the condenser after coming
out of the compressor, releases a lot of heat to the cooling medium, and then
is cooled and liquefied.

3. Evaporator: when the Freon liquid of the
refrigeration system enters the expansion valve for throttling and is sent to
the evaporator, it belongs to the vaporization process. At this time, it needs
to absorb a lot of heat to gradually reduce the valence and mass temperature to
achieve the effect of refrigeration and cooling.

4. Expansion valve: in the refrigerant
system flow chart of the industrial water chiller, we found that there is a
small part between the outlet of the condenser and the inlet of the evaporator,
which is called thermal expansion valve. It is a throttling and depressurizing
part to reduce the condensation pressure of the refrigerant to the evaporation
pressure. Therefore, its role in the refrigeration system is essential. It is
connected with the refrigeration compressor, evaporator, condenser It is also
called the four components of the refrigeration system.

5. Other accessories: including drying
filter and high and low pressure controller. The drying filter is non
detachable. The internal structure adopts molecular sieve structure, which can
remove a small amount of impurities and water in the pipeline, so as to purify
the system. The high and low pressure controller plays a protective role in the
refrigeration system.
