Practice has proved that the use of combined solar heat pipe vacuum tube collectors with lithium bromide absorption chiller air conditioning technology program is successful, it is for the use of solar thermal technology has opened up new application areas. Solar absorption air conditioning compared with conventional air conditioning with three obvious advantages: (1) solar air conditioning season adaptability, that is, the system cooling capacity increases with increasing solar radiation, which is just summer people an urgent requirement for air conditioning consistent; (2) conventional compression chiller Freon media have a great role in the destruction of its atmosphere, and absorption chillers using non-toxic, harmless lithium bromide as medium , it has to protect the environment is very favorable; (3) the same set of solar absorption air conditioning system can be cooling in summer and heating in winter and other seasons hot water combined, significantly improve the utilization of the solar system and the economy.
