Heating, cooling, and environmental control
AiResearch Manufacturing Co. is devloping a low-pressure gas-turbine heat pump whose high efficiency (1.4 to 1.5 coefficient of performance in the heating mode) could save commercial users over $10,000 in energy costs over the life of the system as well as provide a national benefit by saving 250 billion CF of gas from 1982 to 1990 (assuming a growth in market volume to some 200,000 units by 1990). The basic system consists of a gas-fired, Brayton-cycle turbine driving a Rankine vapor-cycle heat pump centrifugal compressor through a magnetic coupling. A unique feature of the system is the use of a semi-open subatmospheric gas-turbine cycle consisting of a centrifugal compressor, radial inflow turbine, recuperator, sink heat exchanger, and in-line combustor. AiResearch expects to test several 10-ton-capacity demonstration units in 1982 while preparing for full-scale production in the mid-1980's.
