Description
A dynamic model for an engine-drlven heat pump has been used to develop and evaluate control strategies for residential and light commercial heat pumps driven by natural-gas-fueled engines. A system comprised of an internal combustion piston engine, open reciprocating compressor, accumulator, coils, and expansion device was simulated in the heating and cooling modes over the range of outdoor temperatures where cycling is expected to occur. Dynamic refrigerant flow is described for each component during a typical start-up cycle, and transient system response is compared with laboratory data to validate the model. Preliminary recommendations for minimizing the losses associated with cycling are offered.
