Heat Pump - 4 Way Valve.
I was wondering if anyone could help please.
I have a quick college question.
Heat Pump -
HEATING MODE - Discharge to indoor coil, indoor coil to compressor suction.
COOLING MODE - Discharge to outside coil, indoor coil to compressor suction.
When these cycles are switched how is the refrigerant metered by the TEV's ? or are the refrigerant flows bypassed and only sent through only one TEV on each cycle ? - I assume one way valves on each side and a bi-flow filter etc..
Any imput ?
