COOLING CYCLE

1.Hot gas from compressor flows through the 4-way valve and is directed to the heating liquid line check valve. It is then con- densed and subcooled through converging circuits. Refrigerant leaves the outdoor coil by way of the strainer and the check valve in the cooling liquid line.

2.The refrigerant then feeds the indoor coil through the Acutrol metering device on each circuit.

3.Each circuit evaporates the refrigerant and the circuits are com- bined in the indoor coil header with some of the circuits flowing through the check valve.

4.The refrigerant then flows through the 4-way valve, accumulator, and back to the compressor.
