ABSTRACT:
The heat pump/engine operates in an open cycle between a cold air reservoir and a hot air reservoir to pump heat or to obtain energy by exchanging air at atmospheric pressure between the two reservoirs at different temperatures.
The heat pump/engine employs a positive displacement compressor, heat exchanger and a positive displacement expander to transfer the air flows. Also, a snowmaker preheater can be used with the heat pump to decrease power consumption.
