Résumé

Gas-driven sorption heat pumps (GDSHP) show significant potential to reduce primary energy use, associated emissions and energy costs for space heating and domestic hot water (DHW) production in residential applications. In this study a bivalent system was considered, characterised by the integration of a novel modular sorption heat pump component and a condensing boiler. The modular heat pump component, or sorption module (SM), has been developed in two types: Type A and Type B, either of which could be integrated into a bivalent GDSHP system. The Type A sorption module had a functioning principle based on a solid chemisorption cycle, while Type B operates under a resorption cycle. To investigate the applicability of each SM type, a bivalent
GDSHP system with a Type A SM (GDSHPA) and one with a Type B SM (GDSHPB) were evaluated. Simulations of year-round space heating loads for two single family houses, one in New York and the other Minnesota, were carried out and the seasonal gas coefficient of performance (SGCOP) for each GDSHP system calculated. The impact of the ratio of the design heating capacity of the SM compared to the peak heating capacity of the bivalent GDSHP was studied. Results show that SGCOP was not significantly affected for SM design heating capacity ratios greater than 66% of the peak GDSHPA design capacity in Minnesota, and 21%
for GDSHPB. In New York, the ratios were 55% and 35% for GDSHPA and GDSHPB respectively.
