Undercharge can cause HIGH superheat. Overcharge can cause LOW superheat. You need some superheat when charged correctly. How much is needed is depending on outdoor air temperature and indoor wet-bulb temperature.
Superheat is measured by calculating the temperature of the refrigerant vapor above its saturation temperature at a given pressure. This is done using a pressure-temperature chart for the specific refrigerant being used. The difference between the actual vapor temperature and the saturation temperature at that pressure is the superheat.
excess superheat in a capillary tube systems means that there is ______ charge
We require to superheat the refrigerant to ensure that no liquid enters in the compressor.So in most of the cases degree of superheat is kept 2 to 3 deg c
true because anything can take up space
The right temperature to superheat and sub cool a substance varies greatly. Water for example takes temperatures above 212 degrees to superheat and temperatures below 32 degrees to sub cool.
Superheat depends on the type of metering device you are using in the equipment as well as the current state of the load. With a fixed orifice, the superheat will be high, about 20 to 30 degrees when the box is warm, down around 10-15 when the box is cold. With a txv, the superheat should be constant, normally between 10-15 degrees. It is best to check the superheat at the outlet of the evaporator. this will ensure that the compressor does not slug with liquid refrigerant.
