which is an important performance index for effective utilization of low-temperature waste heat
a two-stage solid-gas reaction heat transformer system was investigated.The novel heat transformer system was compared theoretically with other systems in literature on the temperature lift and system pressure.The performance of the system was also investigated experimentally.It was concluded that the maximal temperature lift ΔTmax was as high as 70℃; COP and COPex of the system were 0.10—0.12 and 0.16—0.17
