一种新型太阳能辅助多功能热泵的实验研究

EXPERIMENTAL STUDIES ON A NEW SOLAR-ASSISTED MULTIFUNCTIONAL HEAT PUMP

本文提出了一种新型太阳能辅助多功能热泵系统,将家用冷暖空调和太阳能热水器这两种家用节能产品集成起来,不但具有这两种家用产品所独有的运行模式,而且具有四种更加节能的新运行模式。在自行搭建的实验台上成功地实现了六种运行模式的高效运行和运行模式之间的平稳过渡。热泵热水器模式和太阳能辅助室内制热模式的实验表明,系统可以在冬季和春秋季节高效稳定运行,不但可以提高家用冷暖空调和太阳能热水器的利用率,而且具有更好的季节适应性,特别适用于有丰富太阳能,且需要制冷、采暖和制热水的地区。

This paper proposed a new Solar-Assisted Multifunctional Heat Pump（SAMHP） which integrated a solar water heater with a domestic air-conditioner.The SAMHP can operate in all operation modes included in these two domestic appliances,but also in other four energy-saving operation modes for space cooling,space heating and water heating.Six operation modes have been functioned successfully and can be switched to each other smoothly on a purpose built experimental set-up.Experiments of the heat pump water heating mode and the solar-assisted space heating mode have been investigated in detail.The results showed that this new heat pump can operate efficiently and reliably in spring,autumn and winter.The availability of the solar water heater and the domestic air-conditioner will be increased greatly and the adaptability of them will be improved as well.This new heat pump is especially suitable for the regions abundant in solar radiation where the space heating,space cooling and water heating are required all year round.
