How to measure superheat

[@texture6]

Could you show the formula. I did my own division and how did you get 5.8k

Many thanks for your query. Here's the reply, we hope this will help 13 - 7.2 = 5.8 Evaporator exit temp minus saturated evaporating temp. = Superheat

@@instituteofrefrigerationUK hi! is saturated temp another way of saying boiling point? knowing that would help me a lot. Also, why did we get the Suction pressure? I don't see it being used in the equation

@@localchumb thank you for your enquiry - here's the reply from technical: Saturated temperature is the boiling point of the fluid at a given pressure. As the pressure of a fluid changes so does its ‘boiling point’. So with that in mind you need the suction (evaporating pressure) of the system in order to use a comparator to get the boiling temperature of the refrigerant. From this you can then take the actual temperature of the suction pipe leaving the evaporator to calculate the useful superheat in the evaporator. The suction line temperature should be approximated 5k (5 degrees) above the temperature the boiling point.

Sir I want to know that one of systems cooling 20000 ltr water 15c to 14c in 15 minutes, it's cooling capacity?
