Hi!
Sorry for bad english.
I am from europe ( Serbia).
I have outdoor unit R22 18000btu.
I want to create air-water heat pump from this unit.
I want to use it for heating and cooling.
I have a copper tube 8mm and 30m lenght.
And have a tank of 125 litres. First variation is that i made a heat exchanger coil from tube in tank. How i do this? Its good that i make a spiral from copper tube and put in a tank?
If this not good i have a heat exchanger Alfa Laval CB52-22HX. I know that this exchanger is large, but i able to use it for 18000btu outside unit? And the last thing is i have a friend who repairs a refrigitation systems. He tells me that for that compressor (rotary) wich is in outside unit i must use just cappilary tube (wich is in outside unit) as metering device, because the txv will decrease a flow in system and this compressor don't tolerete that. Thanks for help, and again sorry because my bad english.
