According to characteristics of solar radiation in hot summer and cold winter climate zone in China, and hotwater high demand and cooling load of air conditioning of the inpatient departments in summer, a novelequipment integrating shading and domestic water generation is proposed and analyzed by theoretical and experimental methods, which consists of four parts: Arc sun shading reflecting plates, vacuum heat collectingtubes, domestic water tank and cold water supply unit. An inpatient department located in Changsha city isselected as the experimental site. Three kinds of shading and collecting elements were tested by experiments, key design parameters, such as the cross section size of the shading reflector, the solar radiation intensity, the circulating water flow were evaluated. The results showed that: this novel equipment can absorb 2.5–2.8 times heat when compared with traditional vacuum tube solar collector; in the case study, 100% hot water demand of hospital can be met in summer, 31.7% in transitional seasons and 10.8% in winter; the annual air conditioning energy consumption can be reduced by about 2.7% and the annual electricity savings are estimated.
