Working Principle:
The air-cooled explosion-proof chiller mainly realizes
refrigeration through a refrigeration system composed of a
compressor, a
condenser, an evaporator and a fan. It works as follows:
1.The compressor compresses the low-temperature and low-pressure
refrigerant gas into a high-temperature and high-pressure gas,
which is then sent to the condenser.
2.The refrigerant gas in the condenser is cooled and condensed into
a high-pressure liquid by exchanging heat with the outside air.
3.The high-pressure liquid is decompressed through the expansion
valve, becomes a low-temperature low-pressure liquid, and then
enters the evaporator.
4.The refrigerant liquid in the evaporator exchanges heat with the
outside air, thereby absorbing the heat in the air, and evaporating
the refrigerant liquid into a low-temperature and low-pressure gas.
5.The low-temperature and low-pressure gas enters the compressor to
start a new refrigeration cycle.
At the same time, the air-cooled explosion-proof chiller also
introduces air into the condenser and evaporator through the fan
for cooling and heat exchange. Due to the air cooling method, no
water source is required, and it is suitable for places where no
water source is available. At the same time, the air-cooled
explosion-proof chiller adopts an explosion-proof design, which can
operate safely in flammable and explosive places to ensure
production safety.
