基于能量梯级利用的太阳能冷热联供系统

Study on a refrigeration and heating hybrid system based on cascade utilization of solar energy

从能量梯级利用的角度出发,提出了一种新型太阳能冷热联供复合系统。该复合系统可根据太阳辐射强度在不同的季节分别用作单一的太阳能热水器、热泵热水器或太阳能吸附式冷热联供复合系统。建立了相应的数学模型,计算了该系统在不同季节各种典型工况下的性能指标。计算结果表明,该系统不仅可实现冷热联供的双重功能,而且具有较大的节能潜力。

A novel solar adsorption refrigeration and heating hybrid system is proposed from the viewpoint of cascade utilization of solar energy. It can be used as a single solar water heater, a heat pump water heater or an adsorption refrigerator/water heater hybrid system respectively according to the solar radiation intensity in different seasons. A numerical model is developed to predict the performance of the hybrid system under typical climate conditions. Simulation results show that the hybrid can not only realize dual-function of water heater and adsorption refrigerator, but also has a rather energy-saving potential.
