Abstract: Novel multi-step sorption-reaction cycles for air conditioning (cooling, heating) and temperature upgrading are studied. The multi-step sorption-reaction cycle utilizes heat from several processes, such as absorption, dilution, crystallization reaction and thermo-chemical reaction. In the multi-step sorption-reaction single stage solar cooling cycle, the cold storage density can reach the high value of 1.24 kWh/kg. In the multi-step sorption-reaction double stage solar cooling cycle, the 75 °C heat source can drive the cycle to produce cooling effect. In multi-step sorption-reaction heating cycle, the storage density can be improved to the level of 1252 kWh/m3 of solution. In the multi-step sorption-reaction single stage temperature upgrading cycle, the temperature can be improved from 55 °C to 105 °C, while it can be improved from 70 °C to 130 °C in the multi-step sorption-reaction double stage temperature upgrading cycle.
