Description
Technical field: [0001] The invention belongs to the technical field of refrigeration / low temperature waste heat utilization heat pump. Background technique: [0002] In the first type of absorption heat pump, when the waste heat medium flow rate is small and the temperature range is large, the absorption heat pump structure using a single evaporator will cause the heat supply temperature of the absorption heat pump to be not high enough, thus affecting the absorption heat pump. In order to solve this problem, the evaporator should be increased and the segmented absorption should be adopted. At the same time, considering the simplification of the structure and the reduction of the manufacturing cost, in the absorption heat pump with the addition of the evaporator, the addition of other components should be reduced as much as possible. Also, in order to adapt to a variety of different thermal conditions and to achieve continuous performance index of absorption heat pumps, th...
