I wonder if you are talking about reducing super-heat. If that's the case, you should increase the charge. If you reduce the charge, the pressure of both sides will reduce, so the saturation...

AC_Hacker,
I think on the low side it should be super heat, and thus it's sub-cool on the high side. There seems to be a little too much super heat. My theory is that the cap tube you use were for...

My thinking is that if both exchangers are oversized, then both can handle the capacity that the compressor runs at, thus, they may not be exactly the same size but neither will be tested to find out...

I only recently started to read about refrigeration and air conditioning, so I am really not sure about this; but it seems to me that the temperature difference between refrigerant in and out is...

Like AC_Hacker, I tend to believe that most of the issues you listed here can be addressed by design and experimentation. For example, for 1, refrigerant is not supposed to leak out anyway. Ground...

If DX is used on the sink end, as well as the source end, this may be able to solve the problem of refrigerant imbalance between heating and cooling. During cooling, the refrigerant in the floor coil...

One thing about the efficiency is that the compressor you use may not have very high efficiency to start with. I think most window AC units have EER value below 10. The compressors in central AC...

Thanks for the reply, and for the invitation to join. I also believe that when it comes to heating and cooling, GSHP should be the way to go. But the current situation is that the high cost spoiled...

May I ask why you need to drill for closed loop water exchange setting? All the source I learned seemed to use trenches instead of wells. I'm really confused because usually they drill wells (shallow...
