Hello!

I have made modifications to my pump. I have changed heat exchanger and (pipe to plate) and I moved it to house(exchanger).
Now I tryed to refill the system. System works but hi side pressure is about 179F but the pressure on hi side is 320psi. Low side pressure is 70psi and outside temperature is 45F. In my opinion the temperature is too high? What can be reason for that?
And maybe someone can give to me some suggestions how I can finf the right capacity of R410 refrigerant.
Thanks for any help. From Estonia

Measure your system parameters, as per Gary's excellent 'Refrigeration 101' thread, & report back.
