Low grade heat energy requirement, energy saving and environmental protection are the great advantages of the absorption heat transformer （AHT）. The promotion and utilization of this technology is of great significance to solve the current energy crisis. The AHT and its evaluation indexes were summarized. System structures and performance characteristics of several typical structures of the AHT were described. According to the difference of refrigerant, the working fluids of the AHT can be divided into three categories, namely ammonia, water and alcohol series. The research developments of these working fluids were discussed in detail. The future research directions of the AHT were prospected.
