Title: First-Type Absorption Heat Pump with Multi-Terminal Heat Supply

Description:
FIELD 
     The present invention belongs to the area of low-temperature waste heat utilization and refrigeration technique. 
     BACKGROUND 
     In the field of adopting the first-type absorption heat pump to use waste heat, there are some limitations by adopting two heating ports associated with the absorber and condenser to complete absorption heat pump heating process when the heated medium temperature change range is wider relatively. The detailed performance is as follows. The heating temperature of the absorber and condenser associated is similar in a process of the absorption heat pump. The low temperature heating segment and high temperature heating segment of the heated medium can&#39;t be satisfied by adopting a reasonable temperature difference at the same time. Or the heating temperature difference of low temperature segment is larger relatively when the low temperature heating segment and high temperature heating segment of the heated medium is satisfied at the same time. The utilization rate of waste heat is low. And the absorption heat pump process with high performance index can&#39;t be used now. To solve the contradiction, an absorption-evaporator and a high temperature absorber are adopted. The high temperature absorber is used to meet the demand of the heated medium in high temperature heating segment. At the same time, the concentration of the dilute solution entered generator is reduced. The utilization rate of waste heat is higher relatively. In addition, evaporator provides refrigerant vapor for the low temperature absorber by using the high temperature heat load of waste heat medium. And the other evaporator provides refrigerant vapor for absorption-evaporator by using the low temperature heat load of waste heat medium. That is good for realizing the depth utilization of the waste heat resource. The high-temperature thermal driving medium is used deeply by adopting the regenerative process which is formed by the second generator and the third absorber when the temperature change range of high-temperature thermal driving medium is larger relatively.
