SUMMARY Building integrated solar systems have been considered as a reasonable system for building heating, cooling and hot water supply. Various types of solar collectors, such as plate type, evacuated tube type and solar air collector, have been used as the heat source, whereas adsorption chillers, absorption chillers and desiccant dehumidification systems have been considered to match the above solar heat sources. Now, such sorption chillers are more matured, but their coupling with suitable solar heat source is not well researched. Experimental study has been done in this paper to analyse four kinds of typical solar air-conditioning system with different sorption chillers and solar collectors.

Abstract: Compound adsorbent of macro-porous silica gel/LiCl-methanol and micro-porous silica gel–water were used as working pairs in two adsorption cooling systems respectively. The adsorption performance was experimentally investigated and compared. The experiment results are that mass recovery process can improve cooling capacity significantly while heat recovery process can improve coefficient of performance (COP) more significantly. The silica gel/LiCl-methanol cooling system has higher adsorption capacity and working pressure. When the hot water inlet temperature, cooling water inlet temperature and chilled water outlet temperature are about 85°C, 31°C and 15°C, the specific cooling power (SCP) of silica gel/LiCl-methanol cooling system is higher by 59.5% than that of silica gel–water cooling system. The silica gel/LiCl-methanol cooling system can also work for cold storage. When the hot water inlet temperature, cooling water inlet temperature and chilled water outlet temperature are about 88°C, 25°C and −4°C, the cooling capacity and COP are 1.0kW and 0.13.
