simplw question what tmperature would you guys expect liquid and suction on a japanese split unit in full cooling R22,R407 ?

[sedgy]

hi welder, how you doin ? you know you will have to go to the wholesalers and get yourself a compaitor or 2, depending on which gassas you are going to be working on .
on R 22 58psig is the lowest pressure you can have before the evap starts to freeze up,
on R 407 its 68psig,
but I did notice , < when I was on the tools < a long while ago , that the more modern chinese type heat pump ran on a lower psi < suction< possiblt cos they have phisilities to defrost?
hope this helps welder ,, sedgy

I suppose the answer should be -

What temperatures would you expect to see?

[nike123]

Temperatures you are asking are dependent on TD of heat exchangers, their condition (which reflects on actual TD), and temperatures of air which goes in them.
TD depend on heat exchanger construction and amount of air/water.
