Basic Info
Hi,
I'm new to this game and could do with some useful pointers?
1) How do I establish condensing temperature?
2) What is saturated evaporation temperature?
3) How do I establish suction line temperature?
4) How do I establish discharge line temperature?
5) What is sub-cooling?
6) What is work heat?
Any help on the above would be greatly appreciated.

Re: Basic Info
Hi,Pipelini.
1)Your condensing temperature should be 10...15 deg C more than environment temperature in air condensers (5...7 in water condensers).
2)I know only about saturated vapor (conditions of the refrigerant when their last drop vaporized in evaporator, better to say).
3)+4) Temperature increase in suction and discharge line is small (only 3...4 deg C).
5)Sub-cooling is the difference between Tk and temperature after condenser (pressure is the same in both cases).

Hi there,
1) How do I establish condensing temperature?
2) What is saturated evaporation temperature?
3) How do I establish suction line temperature?
4) How do I establish discharge line temperature?
5) What is sub-cooling?
Sub-cooling = tc - t1
6) What is work heat?
Hope this helps.
