摘　　要：提出了一种新型的集热/蓄能/蒸发一体化太阳能热泵热水器.该系统将太阳能集热器、蓄能容器以及热泵系统的蒸发器集于一体,减少了现有蓄能型太阳能热泵系统多级中间换热的热损失及制造成本.在集热/蓄能/蒸发器中加入相变材料,以固-液相变潜热对太阳能进行储存,利用太阳能作为热泵的低温热源制得热水,将显著提高热泵的制热效率,同时有效解决太阳能的间歇性所带来的系统运行不稳定问题.虽然初投资费用有所提高,但是该系统无论是在节能还是在节约运行费用方面都优于市场上的各种热水器,和现有的蓄能型太阳能热泵热水器相比则降低了成本,简化了系统,提高了运行可靠性,具有十分广阔的应用前景.A novel solar heat pump water heater integrated with collector, storage and evaporation is presented, and this novel system can reduce heat exchanging losses and manufacturing cost. By adding phase-change materials into the collector/storage/evaporator, the solar energy is storied as latent heat of solid-liquid phase materials. By making use of the solar energy as low-temperature source to produce hot water, the thermal efficiency of heat pump system can be significantly increased; moreover, the operating unstability of the heat pump system caused by interval solar energy can be drastically solved. Though the initial investment is increased, the system is better than the existing water heaters in the market in terms of whether saving energy or saving costs. Compared with the existing solar-energy storage heat pump water heater, the advantages of lower cost, simplified system and higher reliability would bring this novel heat pump water heater to be widely applied.
