Not something that i work on but something that i can't seem to find on google.
Say for instance in a commercial refrigeration application i select a compressor say for example 3hp for instance has a capacity of 8.5kw (coolroom) at an evaporating temp of -5c. Now if i use this same 3hp compressor for a freezer application and now has an evaporation compressor 4kw at an evaporating temperature of -25c. Now my question is how does the suction pressure/temperature change? From reading it the temperature difference of the coil, but what exactly gives a coil a certain evaporating temp? Size of pipes, length, volume etc if you get the jist. Just something that's been teasing my brain of late Thankyou
