Hello, need some help explaining this situation. A customer of mine has a game room that works on ONLY one unit with dual compressor. He initially has two workable packaging units, but for whatever reason only one is now hooked up to the building. Because of the heat load inside the building, the compressor #1 will tripped and he has to go and reset the high pressure switch. It will run for about five minutes and tripped and the compressor #2 kicks in. The second will keep running and never tripped. Compressor #1 seems to govern the ductwork around the thermostat area and when tripped will blow out hot air. Compressor #2 seems to govern the middle part of the room and blows out cool air. In addition, he has invested two portable units that are hooked up around the opposite wall of the thermostat because there are no air duct around that area. Okay, so heres a few of his questions:
1. How do these two compressors work hand in hand with each other? Are there two separate coils for each compressor one feeding to one area of the room and the other to the other area of the room?
2. Why is compressor #1 keeps tripping and compressor #2 never trips? Can we conclude that compressor #1 is bad?
3. If we replace compressor #1, will we resolve the problem? Can we take the compressor from the other unit (one that is not hook up) and replace it onto compressor #1?
4. Why is the section around the thermostat area hot when compressor #1 tripped and the middle section stays cool? When not tripping all areas is cool.
I really need some guidance because I cant seem to explain it clearly to him. Please help.
