Performance of Gas Engine-Driven Heat Pump System for Supplying Domestic Hot Water in Transitional Seasons
In this study, the performance characteristics of gas engine-driven heat pump (GHP) system for supplying domestic hot water in transitional seasons were investigated. The influence of the recovered engine waste heat on the GHP system was analyzed. The changes of the heating capacity of domestic hot water (
