Mitsubishi P series refrigeration cycle question

BigRob

The condenser unit has two expansion valves.. one for the evaporator and one at the end of the condenser circuit before it goes into what looks like a receiver but the evaporator and condenser circuits both go into this receiver."

What is Mitsubishi doing, especially with the "receiver?"

HVACNUT

It's a heat pump. In heat mode the condenser is the evaporator and needs the EEV.

I should have mentioned it's a PUY series (cool only). Just double checked the nameplate.

I guess it's for condenser head control? Also why to all the line set circuits pass through the "receiver?"
