间接膨胀式太阳能多功能热泵系统(indirect expansion solar assisted multifunction domestic heat pump,IESA-MDHP)的运行性能受到多种因素影响,利用带有太阳模拟发射器的焓差实验室可定量检测热泵系统的运行性能,并对不同条件下的运行性能进行比较。该文在稳定的外界条件下,对IESA-MDHP系统在太阳能制热水模式和太阳能制热模式下运行的换热性能进行实验研究。结果表明,在太阳能制热水模式中,随着水箱初温升高,蒸发侧和冷凝侧换热功率均会提高,在制热水的同时,向系统输入太阳辐照,与无辐照时相比,辐照强度从0 W/m~2上升到500 W/m~2时,系统在蒸发侧和冷凝侧的平均换热功率可分别提高30.11%和37.46%,平均COP可提高32.27%;在太阳能制热模式中,水箱作为系统的蒸发热源,水箱初始温度越高,蒸发侧换热功率越大,对应的冷凝侧换热功率随之增大。
The operating performance of an indirect expansion solar assisted multifunction domestic heat pump (IESA-MDHP) is affected by many factors, and enthalpy difference laboratories with solar simulators can quantify the operation of the heat pump system Performance, and run under different conditions to compare performance. In this paper, under the condition of stable external environment, the heat transfer performance of IESA-MDHP system operating in solar water heating mode and solar heating mode is experimentally studied. The results show that in solar water heating mode, as the initial temperature of the water tank increases, both the heat transfer efficiency of the evaporation side and the condensation side will increase. When the hot water is supplied to the system, the solar radiation is input, and when there is no irradiation The average heat transfer power of the system on the evaporation side and the condensation side can be increased by 30.11% and 37.46%, respectively, and the average COP can be increased by 32.27% when the irradiation intensity increases from 0 W / m ~ 2 to 500 W / m ~ In the solar heating mode, the water tank is the evaporation heat source of the system. The higher the initial temperature of the water tank, the greater the heat transfer power on the evaporation side and the corresponding heat exchange power on the condensation side increases.
