Hello, I’m reaching out to the community to help clear something up for me! I’m currently reviewing the HVAC specifically air conditioning. So I understand that the liquid refrigerant flows into the expansion device then into the evaporator coil where it then boils and vaporizes and receives heat from the interior air. Afterwards the heated vapor then moves to the compressor and condenser where the heat gets released by the air blowing through it and the refrigerant re-condenses into liquid and the cycle repeats. So my question is when the vapor receives heat from the interior wouldn’t the suction line be warm from receiving the interior heat and not the liquid line because it just released the heat? InterNachi says the liquid line will be warm which is why I’m confused because it doesn’t sound logical.
Thanks for the help in advance!
