An absorption heat pump technology have been applied for a low temperature waste heat recovery. Two types of absorption heat pump systems have been researched and are identified as "first type" and "second type". The "first type" system is the same as an absorption chiller. The "second type" system can produce usable heat at a higher temperature than the heat source, so it is called a temperature boost absorption heat pump. In this article, the theoretical analysis of this temperature boost heat pump is briefly explained, and experimental results on the prototype heat pumps are shown. To generate high temperature steam from waste hot water, we produced second type absorption heat pumps as prototype, and experimented. A single stage heat pump could generate 0.2MPa(A) steam, when the hot water temperature was 80℃ and the cooling water temperature was 32℃. And the same temperature condition of hot water and cooling water, a double-stage heat pump could generate 0.8MPa(A) steam.
