“…Therefore, SWH systems can meet the temperature requirements except, perhaps, in extreme weather conditions. The latest SWH product technologies (with advanced heat pump and heat pipes) can produce water at a temperature above 60 1C under all weather conditions (Chyng et al, 2003;Wang et al, 2000). However, there remain two major technical concerns with SWH in China.…”

a b s t r a c t Solar thermal utilization, especially the application of solar water heater technology, has developed rapidly in China in recent decades. Manufacturing and marketing developments have been especially strong in provinces such as Zhejiang, Shandong and Jiangsu. This paper takes Zhejiang, a relatively affluent province, as a case study area to assess the performance of solar water heater utilization in China. The study will focus on institutional setting, economic and technological performance, energy performance, and environmental and social impact. Results show that China has greatly increased solar water heater utilization, which has brought China great economic, environmental and social benefits. However, China is confronted with malfeasant market competition, technical flaws in solar water heater products and social conflict concerning solar water heater installation. For further development of the solar water heater, China should clarify the compulsory installation policy and include solar water heaters into the current ''Home Appliances Going to the Countryside'' project; most of the widely used vacuum tube products should be replaced by flat plate products, and the technology improvement should focus on anti-freezing and water saving; the resources of solar water heater market should be consolidated and most of the OEM manufacturers should evolve to ODM and OBM enterprises.

“…For this reason, adsorption chillers have attracted some research interest. For example, a university team in China looked at the solar powered adsorption chiller to make ice [126] . Some other researchers have modeled the transient behavior of a solar powered adsorption chilling process [81] .…”

“…The solar energy collector is consisted of 30 φ47×1×1200 glass vacuum tubes whose collect area of solar energy is 4.2 m 2 . SrCl 2 -NH 3 is used as working pair of adsorption refrigeration (SrCl 2 is used as the adsorbent, and NH 3 is used as refrigerant ) 4) , structure of adsorber adopted by this paper is shown in Fig 2. It is made up of unit generating tubes, Configuration of unit generating tube is shown in Fig 3. Unit generating tube is made up of aluminum fin in which SrCl 2 is filled, ammonia-conducted tube and stainless steel tube. Ammonia-conducted tube is the passage of ammonia vapor flowing into/ out generating tube, and stainless steel tube is a heat exchanger in which heat exchangeis conducted when warm water is flowing.…”

Based on the vacuum tube type solar collector, a system of hybrid solar powered water heater and adsorption ice maker was designed and a prototype was built. Energy analysis of the hybrid system was presented, and the prototype was experimental tested in different season. The results of analysis and experiment show that, compared with the traditional solar powered water heater and cooling machine, the hybrid system is more suitable for household usage.Keywords: solar energy; adsorption refrigeration; water heater IntroductionThe utilization of solar energy is a major characteristic of modern " green building", it is concerned by scientists around the world and some progress is made. There exist two types of solar collector 3) : photovoltaic cell and purely thermal collector, the latter is more common in the application of solar energy. Based on the purely thermal collector, solar powered heating and cooling system of building are developed, some products are used.The technology of solar powered heating system is developed successfully, it is widely used in solar powered water heater. The product of solar powered water heater is popularly used in China, nearly 10% of water heaters in China is powered or partly powered by solar energy, the percentage is still increasing quickly. The solar powered water heater has advantages of environmental friendliness and energy conservation, but it has some disadvantages. The main disadvantage of it is that the supply of solar energy and the need of heated water do not agree with each other in the same season. In summer, the supply of solar energy reaches maximum level, but the need of heated water is minimum, in winter, it is in the opposite situation. So the utilization of solar energy of water heater is not sufficient.The technology of solar powered cooling system is developed too. It is an excellent application of solar energy, because the supply of solar energy and the need of refrigeration both reach maximum level in the same season (summer), and the utilization of solar energy is sufficient in that season.
