with about 70% humidity and I tested the HP in the normal heat mode. OMG what was I thinking. Gee the reversing valve operated normal and I had nice cool air being discharged from the outside condenser and nice warm air into the home.
So as you can see it the pic the unit did did not melt or go poof and disappear and it operated real normal when I switched it back to cooling.
Actually I don’t operate the unit in the normal heat mode just long enough to see if the reversing valve operates as intended.
This HP is not a pump down unit so why does it have a solenoid valve in the liquid line going to the A-coil???
Ok lets try this if you and your client are standing in front of the A-coil and the client ask you whats that thimagiggy in the freon line do what are you going to tell him, is your face going to get red when you say I will call Dave Andersen and find out:p:D:mrgreen:
I am surprised no one had the true answer James M was all around it but not quite correct. I must admit I had never seen this set up on a heat pump before all I can say is leave it to Carrier to be different.
Understanding the refrigerant flow of a HP and the liquid and vapor state of the refrigerant in the various areas of the system during the cool and heat modes one should be able to determine what that solenoid valve does.
I have another question to put on the table how would a person be able to tell if a solenoid valve has voltage applied to its coil without the use of a electrical meter or twiggy
