Prototype commercial hot water gas heat pump (CHWGHP) - design and performance


Describes a gas-fired hot water absorption heat pump developed in the US incorporating generator-absorber heat exchange to deliver hot water above 60degC (140degF). States that with a gas coefficient of performance of 1.54, one-third of the gas used for commercial water heating can be conserved. The heat pump also provides 'free' cooling with evaporator temperatures as low as -10degC. The projected payback for the typical commercial customer is about two years. Summarises the prototype design and testing, verification of component performance, heat pump capacity, temperature lift, water delivery temperature and coefficient of performance.
