Title: Rankine/Rankine cycle gas-fired heat pump

Technical Report ·
OSTI ID:6250836

Two rotating elements, a high - speed turbomachine core and a low-speed assembly that includes a rotating vapor generator and heat exchangers - comprise MTI's prototype residential Rankine/Rankine cycle gas-fired heat pump. One Rankine cycle, the power cycle, drives the turbine and releases its excess heat to the service air; the second, the refrigerant cycle, is pressurized by a turbine-powered centrifugal compressor. A conceptual design study of an end-product model and a product specification for a family of heat pump systems with various performance enhancement options suggest that the maximum-performance end-product heat pump system has a projected overall coefficient of performance (OCOP) of 0.79 at a 37,500 Btu/hr cooling load and 1.49 at a 60,000 Btu/hr heating load. This end-product model has an estimated manufacturing cost of $1460 (1982 $) and could be commercially available by the early 1990s.
