“…PER decreased by 15.3% under the condition of the engine speed varied from 1300 to 1750 rpm [8]. Furthermore, the cooling performance of a gas engine heat pump system with the important factors, such as, evaporator water inlet temperature, evaporator water volume flow rate, ambient air temperature and gas engine speeds, were also investigated [9,10]. Yang et al [11] established a thermal model of a GEHP system working as water heater and studied the performances of the GEHP system.…”

“…Operation of gas engine drives, especially during the peak time of the day when electric demand charges are highest, results in additional savings. [29] Many researchers have studied GEHPs, but most of them have devoted their attention to energetic performance analysis of the units by way of field tests. [30][31][32][33][34] Very few investigations were related to the GEHP system modeling.…”

Exergoeconomic analysis has been used as a powerful tool to study and optimize various types of energy-related systems. In this study, we use the specific exergy cost (SPECO) method to calculate exergy-related parameters and display cost flows for all streams and components in a gas engine-driven heat pump drying system based on the experimental data. We analyze and evaluate the performance of the drying system components and the drying process for three different medicinal and aromatic plants from an exergoeconomic point of view. We also investigate the effect of varying dead (reference) state temperatures on exergoeconomic performance parameters for the drying system components and drying process. Although the condenser and drying chamber of the gas enginedriven heat pump dryer were significantly affected by the ambient temperature, the gas engine was slightly influenced by the ambient temperature. At low ambient temperatures, the exergy rates increased and the most effective performance obtained from this dryer was at 0 C. The performance of the drying process also increased at low ambient temperatures. This study demonstrated that exergoeconomic analysis can provide more information than exergy analysis, and the results obtained from the exergoeconomic analysis provided cost-based information, suggesting potential locations for drying system improvement.

An eQUEST model was developed to conduct a study of a natural gas engine driven heat pump (GEHP) for an office building in Woodstock, Ontario. The results were also compared with a roof-top unit to investigate annual potential energy saving using GEHP. The models were also calibrated with regression analysis which was obtained from measured data and validated with respect to ASHRAE Guideline 14-2002. The developed ad validated models were used to predict the performance of these system in different regions of Ontario; Toronto, Ottawa, Windsor and Thunder Bay. The results for five cities were compared in terms of annual energy, GHG and energy cost savings. It was concluded that Thunder Bay has the highest annual energy and GHG saving, while Toronto has the highest annual energy cost saving.
