The heat pumps i´ve been having issues with recently I´m sure are down to design issues.
I have noticed something which I think is quite relevent to the opertaion of the heat pump.
1. The TXV bulb is on the bottom (horizontal) of a "u" bend.
2. The The TXV bulb is after the equalising line for the TXV.
3. Both the bulb and equalising line are after the 3-way valve.
I believe all these things are incorrect and would lead to the problems I have been having with the suction line pressures and temperatures flucuating. Am I correct in thinking this?
I have attached pictures to demonstrate what I mean. The suction line bends up behind the the accumulator then bends 180º on to the top of the accumulator.
:off topic: I´ve made a new thread so not to confuse my other thread. If the mods want me to put this in there, then let me know and i´ll post it in there instead.
