Central Air Conditioner Water - Cooled Type
Shell and Tube Heat Exchanger
The working principle of the chiller The refrigerant (ie
refrigerant) absorbs the heat of the cooled material
and vaporizes it into steam in the evaporator.
The compressor continuously draws the generated steam from the
evaporator and compresses it. After
compression, , High-pressure steam is sent to the condenser after
the cooling medium (such as water, air,
etc.) heat condensed into high-pressure liquid, the throttle
through the throttle body after the pressure
into the evaporator, vaporized again to absorb the heat of the
object, cycle. Heating, the refrigerant
through the four-way valve to change the direction of refrigerant
flow, the direction of refrigerant flow and
refrigeration just the opposite, the refrigerant first through the
evaporator, and then back to the
condenser, and finally back to the compressor.
The liquid refrigerant in the evaporator absorbs the heat in the
water and begins to evaporate. Finally, a
certain temperature difference between the refrigerant and the
water is formed.
The liquid refrigerant is completely evaporated into a gaseous
state and sucked and compressed by the
compressor (pressure and temperature increase ), Gaseous
refrigerant through the condenser (air-
cooled / water-cooled) to absorb heat, condensed into a liquid.
Through the expansion valve (or capillary) after the throttle into
low-temperature low-pressure refrigerant
into the evaporator to complete the refrigerant cycle process.
