摘要：
Heat tranformers are devices with the unique capability of raising the temperature of part of a low-grade heat source whilst simultaneously delivering the rest of the heat at a lower temperature. The gross temperature lift that could be attained in the process depends on the characteristics of the working pair. Many combinations of working fluid/absorbent have been proposed although until now the water/lithium bromide system is the most widely used. In order to study the performance of combinations of environmentally friendly working pairs, an absorption heat transformer was constructed and tested. The experimental equipment is described in this work. The performance of the water/lithium chloride system is discussed. The results showed that gross temperature lifts of more than 30 degrees C can be obtained for absorber temperatures higher than 110 degrees C. The enthalpic coefficient of performance indicated that more than 45% of the waste heat can be upgraded for flow ratios less than 10.
