The refrigerant flow diagram details the piping layout and equipment connections for a condensing unit and connected mechanical equipment. A double riser suction line connects to the circuit with a hot gas bypass valve installed close to the compressor discharge line. Liquid line filter-dryers, solenoid valves, sight glasses, and thermal expansion valves with external equalizers are incorporated along the refrigerant lines.
