Generated explanation

The illustration diagrams an air-conditioning refrigerant circuit, with a dashed vertical line separating indoor and outdoor components. Warm indoor air passes toward the evaporator coil, and warm refrigerant gas flows from that coil to the outdoor compressor. Hot gas leaves the compressor and enters the condenser coil, where warm air is discharged outside the house. Refrigerant labeled hot liquid returns toward the expansion device, then enters the evaporator as cold liquid. Arrows indicate flow direction, and callouts identify the low-pressure side near the evaporator inlet and the high-pressure side at the condenser outlet.
