Operation
The table below describes how the DX cooling system works.
Phase
Description
1
The compressor (2) extracts the gaseous cooling agent under low
pressure from the evaporator (10), and forces it under high pressure
and high temperature to the condenser (3).
2
The fan sucks air over the cooling fins of the condenser, so that the
gas condenses into a fluid at a lower temperature.
3
The fluid created in this way leaves the condenser under high
pressure.
4
The thermostatic expansion valve (11) injects the fluid into the
evaporator (10).
5
The fluid in the evaporator takes the heat from the milk in the tank and
evaporates. This is how the milk is cooled.
6
The compressor (2) extracts the gas created and the cycle starts again.
