Development and demonstration of an ammonia-water absorption heat pump
Abstract
Development of a residential air-source ammonia-water absorption heat pump designed to operate in the heating mode only and deliver its output as hot water is described. A prototype unit was developed and plans to operate three life test and three field test units in a northern climate during the winter are described. Prototype specifications are 50,000 Btu input, 125 F supply water, 105 F return water, and COP 1.25 at 47 F ambient and COP 1.12 at 17 F ambient.
