    摘要: A heat pump is provided having a first heat exchanger and a second heat exchanger. A compressor is fluidly coupled to the first heat exchanger and the second heat exchanger. A reversing valve is fluidly coupled between the first heat exchanger and the second heat exchanger. The reversing valve is adapted to flow of a refrigerant from the compressor to the first heat exchanger during heating mode and to the second heat exchanger during a cooling mode. A thermal expansion valve is positioned between the first heat exchanger and the second heat exchanger. An electronic expansion valve is positioned between the first heat exchanger and the second heat exchanger. A controller is electrically coupled to operate the electronic expansion valve between a fully open, a fully closed and a modulated position depending on the operation of the compressor.

    摘要: An electronic apparatus externally detects open protector contacts inside of a compressor. The compressor includes a compressor motor having a run winding and a start winding. The compressor motor also includes internal protector contacts that open the electrical circuit to the “C” terminal in a protection condition. A compressor running indicator circuit is electrically connected between the “S” and the “R” terminals to indicate a compressor running condition. Also, a protection indicator circuit is electrically connected between the “C” and the “S” terminals to indicate a voltage present across the “C” and the “S” terminals. The protection indicator circuit is also coupled to the compressor running indicator circuit such that the protection indicator circuit is disabled when the compressor is running normally and the protection indicator is enabled and indicates when protector contacts open inside of the compressor.

    摘要: The present invention relates to a method for alleviating a short-term "cold blow" effect in a heat pump heating system. According to a method of the invention, reversing of a system valve in response to the sensing of a defrost condition is delayed by a predetermined time. The amount of this delay time depends upon the amount of time required for a supplementary heating unit to achieve an output sufficient to offset the cooling effect resulting from there being a cold indoor coil.
