Gas fueled space conditioning heat pump research in the United States.

摘要

Both gas-engine-driven mechanical vapor compression and gas fuel thermally activated sorption space conditioning heat pump technologies are under development in the United States. The residential 3RT gas-engine heat pump has successfully completed a 10 unit field test and is entering a 50 unit field demonstration phase supported by the manufacturers and the gas industry in the endeavor to commercialize this new HVAC technology. Several sorption technologies, including absorption, adsorption, and chemisorption of ammonia vapor are in various stages of development. Prototype ammonia-water absorption GAX systems have been built and tested in the laboratory with expectations of entering a field test in 1993. Solid-vapor, ammonia-carbon, and ammonia-salt systems are in laboratory system development and bench scale component development stages respectively. All face economic trade-off issues regarding cost and performance.
