| Popis: | Due to serious energy shortage, it is urgent to reduce energy consumption from burning of fossil fuels. Driven by low-grade heat, absorption system is a promising energy conservative air-conditioning system for buildings. However, the main obstacle is the poor performance as a result of the energy waste in conventional thermal regeneration process. With the aim of performance improvement, a heat localization method is proposed for the regeneration process of absorption system. It can improve energy utilization efficiency through thermal energy localization on the evaporation surface. Preliminary experiments have been conducted to test the regeneration performance with this new method. Some parameters have been investigated with the experimental data. Moreover, by comparison between the heat localization method and traditional heating method, it indicates the energy utilization efficiency with the heat localization method are 1.8 to 2.8 times higher than that with the traditional heating method. The performance of the system has been greatly improved. The energy utilization efficiency of the regeneration process can reach 36.9% under certain working conditions. With the performance improvement, the popularization of absorption system will be promoted. |
