In vapour compressor refrigeration system the low pressure and temperature vapour refrigerant from evaporator is compressed. where it is compressed to a high pressure and temperature. From compressor refrigerant goes to condenser where where it changes the phase. from condenser refrigerant goes to evaporator through expansion device.
Evaporator is said to be flooded type if liquid refrigerant covers the entire heat transfer surface. This type of evaporator uses a float type of expansion valve. An evaporator is called dry type when a portion of the evaporator is used for superheating the refrigerant vapour after its evaporation.
A Reverse cycle Air conditioner is MUCH more efficient than resistance heating. It is called a heat pump, and requires that the Evaporator and Condenser coils of a Closed Refrigerant System be reversed.

Do you mean Evaporation? If so Evaporation is the Opposite of Percipitation ( the falling of rain ) so Evaporation is water rising into the atmosphere and becoming rain clouds which is then moving in the Water Cycle to the next point which is Percipitation.
Evaporator Approach is the difference between the evaporating refrigerant temperature - measured at the well in the evaporator -and leaving chilled water temperature.Take all readings with the water cooled chiller at full load.Condenser Approach is the difference between the liquid refrigerant temperature - as measured on the liquid line - and leaving condenser water temperature.

In vapour compressor refrigeration system the low pressure and temperature vapour refrigerant from evaporator is compressed. where it is compressed to a high pressure and temperature. From compressor refrigerant goes to condenser where where it changes the phase. from condenser refrigerant goes to evaporator through expansion device.
The evaporator
The heat is released by heat exchangers in the atmosphere.

In dray expansion evaporator, the liquid refrigerant is generally fed by an expansion valve. the expansion valve controls the rate of flow of refrigerant to the evaporator. In the evaporator the liquid refrigerant is vaporized and superheated by the time it reaches to the end of evaporator. At inlet of the evaporator, the refrigerant is predominantly in the liquid form with a small amount of vapor formed as a result of flashing at the expansion valve. the liquid refrigerant passes through the evaporator, more and more refrigerant is vaporized by the load. according to the load, the liquid will come into evaporator and vaporize and reaches to superheat at the end of the evaporator. The inside of the evaporator is far from dry but wetted with liquid so named as dry expansion evaporator.
an evaporator is a part of a refrigeration plant by which the refrigerant is made to boil at a much lower temperature and pressure. the idea is to extract the heat from the region which we want to cool. basically the evaporator is located at the region where the thing to be cooled is situated.
I'm just a student of HVACR and I think a lack of refrigerant will be indicated by a warm an evaporator or the outlet end of the evaporator.
