燃氣機熱泵熱水器系統(tǒng)的理論與實驗研究
[Abstract]:Gas engine heat pump water heater system is a new type of device which takes natural gas as the primary energy input, provides cooling capacity for building refrigeration season, heat supply during heating season and daily hot water supply all the year round. In this paper, the theoretical simulation and experimental study of gas engine heat pump water heater system are carried out. Based on gas engine heat pump water heater system, the mathematical model of gas engine and heat pump system is established. The performance of gas engine heat pump water heater in winter heating season is studied by means of experiment and simulation. The results show that the model can effectively predict the performance of gas engine heat pump water heater. The operating characteristics of gas engine heat pump water heater in cycle heating mode and primary heating mode are compared and studied. The environmental temperature and cooling water flow rate of condenser are mainly considered in the research process. The effect of refrigerant superheat and engine speed on the performance of the system shows that the system has higher primary energy efficiency when running in primary heating mode. In the cooling season of gas engine heat pump water heater, plate heat exchanger is used as condenser instead of finned tube heat exchanger as condenser. At the same time, condensing heat of condenser and waste heat of gas engine are recovered to produce hot water for domestic use. The results show that the primary energy utilization rate (PER) of the system is significantly increased after the condensing heat is recovered. When the engine speed is 1900rpm, the minimum PER value of the system is also as high as 1.79, and the energy saving effect of the system is remarkable. Based on the meteorological statistics of four cities in China, the energy efficiency of gas engine heat pump water heater system in refrigeration season is higher than that of (SEER), refrigeration season. The energy efficiency of primary energy in the refrigeration season is (SPERr),. The seasonal energy efficiency ratio (HSPF) and primary energy efficiency (SPERh) of heating season were calculated. Based on the consideration of engine speed and ambient temperature, the definition of integrated primary energy efficiency (PERzh) is proposed, and the operation of gas engine heat pump water heater in non-cooling and heating season is evaluated. On the basis of experiments, the PERZ value of the system is calculated to be 1.453. The system has a high primary energy utilization rate, and the energy saving effect is obvious.
