Air conditioner/heat pump conversion apparatus

摘要: Heat pump/air conditioning converter apparatus for directing a refrigerant from compressor to first heat exchanger located within building and second outside the selectively cooling heating exchanger. The has housing which reversing valve, liquid flow control valve system, an expansion accumulator tank is incorporated. number of cavities receiving various components valves tank, passageways minimize external connections. incorporates axially slideable rod having large main piston positioned centrally thereon pair smaller opening/closing members at each end, one end controlling hot high pressure gaseous other low relatively cool refrigerant. includes ball moved by fluid check in path valve. disposed between portion accessible filter elements path.
