Abstract
The objective of this work is to simulate a single effct (SE) ammonia-water heat pump for domestic water heating, with innovative aspects for cycle simulation and eventual implementation. Seasonal temperature variations demand verfication of distillation column viability. For the given application and temperature ranges, it is found that some variables need to be controlled if the same column is to be used all year round. In addition, a number of simplifications are considered in this work: an advanced evaporator requireing minimal gas flow and surface area, subcooling at two crucial spots of the cycle and the viability of some pump designs to assuage cavitation issues.
