Compressor

When the refrigerant coming from the evaporator is a tank pressure in the tank will grow until it equals the pressure in the evaporator. Thus, the refrigerant flow stops and the temperature in both tank and evaporator will gradually rise to the surrounding world.

To maintain a lower pressure, and, with its lower temperature it is necessary to remove vapors. This is done by the compressor, which sucks vapor from the evaporator. In simple terms, the compressor can be compared to the pump which sends vapor in the refrigeration circuit.

In the closed circuit of the state of equilibrium will always prevail. To illustrate this, if the compressor sucks vapor away faster than it can be formed in the evaporator pressure will fall and with it the evaporator temperature. Conversely, if the load on the evaporator rises and refrigerant evaporates faster, pressure and temperature in the evaporator will grow...
