英文摘要：

A combined cold and heat energy storage of thermochemical sorption heat transformer technology was introduced. And based on that, an experimental facility was organized based on NaBr-NH3 working pair. The performance of the system was studied to confirm the effect of the technology. The experiment result is： In the heat pump condition, when temperature was lifted 15 ℃, the heat storage capacity is 258kJ/kg. In refrigeration condition, the refrigeration storage capacity can arrive 525kJ/kg, the COP can arrive 0.3 and SCP can reach 175W/kg. The research results showed that： Thermochemical sorption heat transformer has great potential in high efficient utilization and storage of low-grade energy. While at the same time, the technology can also realize the of cold and heat energy storage.
