take your gages and put them on the beginning of the evaporator (afte metering device or txv) and look at saturation temp then get your temp at the suction line (before the compressor)
how do you calculate the rate of osmosis
yes.
calculate the no of pipes in the circuit & then work out the volume based on the area.
You can calculate mortgage by using the online calculator that you can find on some websites for calculating mortgage. Such calculators are the one for bankrate.
Normally, ambient.
take your gages and put them on the beginning of the evaporator (afte metering device or txv) and look at saturation temp then get your temp at the suction line (before the compressor) then take you first temp and your second temp and subtract you highest temp from you lowest temp and that would be your superheat
To calculate superheat, subtract the actual temperature of the refrigerant from its saturation temperature at the current pressure. This will give you the superheat value, indicating how much the refrigerant has increased in temperature above its saturation point. Superheat is important in ensuring optimal functioning of air conditioning and refrigeration systems.

just subtract the highest temp. - lowest temp
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
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.
You cant.
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.
