Psig Saturated Temp Suction line temp superheat temp.
58 32 44 12
64 37 47 10
70 41 50 9
can some1 help me understand the ratings above..
Saturated temperature is easy ok.
Suction line temperature is the temperature before or after the evaporator? my guess is after the evaporator..
As for the superheat temperature: they say it defines the liquid content of R-22 in the system at the exit of the evaporator, but i don't understand the principle (like is it a set value? or given by the compressor in use...?)..please help with this.
2. Choosing a compressor: I'm finding that their is a conception that if u need to transfer 10 tons of cooling to a room, u choose a compressor that is rated at 10 tons. but shouldn't a smaller one do?
thnx
