燃气机热泵供热性能规律的理论和实验研究
Theoretical and experimental study on heating performance of gas engine-driven heat pump
摘要
Abstract
The gas engine-driven heat pump (GEHP) system is an efficient energy saving and environment- friendly heating system which consumes natural gas as fuel in a gas engine. The present work aimed at evaluating the performance of a gas engine-driven heat pump for heating. In order to achieve this objective, a test facility was developed and experiments were performed over a wide range of engine rotary speed (1300—1900 r·min−1). The relationships of engine rotary speed, condenser water inlet temperature, condenser water flow and system performance [heating capacity, system coefficient of performance (COP) and primary energy ratio (PER)] were studied based on theoretical analysis and experimental data. The results showed that the heating capacity of GEHP increased with increasing engine rotary speed and condenser water flow rate, but decreased with the increase of condenser water inlet temperature. The COP and PER of the GEHP decreased with increasing engine rotary speed and condenser water inlet temperature. The effect of the engine rotary speed and condenser water inlet temperature on the system performance was more significant than that of condenser water flow rate. The waste heat recovered from the gas engine accounted for about 40% of the total heating capacity, and the PER of the GEHP was between 1.15—1.47 under experimental condition.关键词
