Abstract
A split reversible heat pump/air conditioning system employs a single, bulbless thermostatic expansion valve (TEV) that spans both the common liquid line and the suction line. The system includes a compressor that supplies a refrigerant flow along a refrigerant pathway; an indoor heat exchanger; an outdoor heat exchanger; a reversing valve located along the refrigerant pathway between the outdoor heat exchanger and the compressor, and between the indoor heat exchanger and the compressor; and a bulbless TEV comprising a valve portion located along a common liquid line of the refrigerant pathway between the indoor heat exchanger and the outdoor heat exchanger that throttles the refrigerant flow as between the indoor heat exchanger and the outdoor heat exchanger, and a sensor portion for sensing pressure and temperature located along a suction line of the refrigerant pathway between the compressor and the reversing valve.
