Application of solar air heating system in Tibet area

Designs a set of solar air heating and hot water system. Presents the design scheme, operation characteristics, system components and control principle in detail. Through its practical application in Tibet area, analyses the economic performance and applicability of solar heating system. The results indicate that the solar air heating system operates stably and the indoor temperature can be maintained at 18 ℃.  Compared with gas-fired boilers and electric heating boilers, the energy saving effect of solar heating system is more obvious with the increase of the running years. The standard coal can be saved up to 257.36 tons in a single heating season.
