Abstract
Various methods for reducing the purchased, resource energy consumption of vapor-compression heat pumps in both heating and cooling modes are analyzed and compared to conventional systems. The results are presented in detailed system analysis curves for the relevant range of major design parameters. One of the methods studied is the application of a solar-powered, fuel-superheated Rankine cycle incorporating a steam turbine. This cycle would drive the heat pump in the cooling mode. Fuel-fired, it would drive the heat pump in the heating mode, with system performance augmented by utilizing the waste heat from the cycle, as well as by solar energy.
In the cooling mode, resource energy savings of 50–60% are obtained. In the heating mode, resource energy use is reduced 3 to 4 fold.
