Its performance is that in an absorption heat pump process, the heat supply temperature of the associated absorber and condenser is similar, and its heat supply often cannot satisfy the low-temperature section of the heated medium at the same time under the premise of a reasonable temperature difference. and high-temperature section heat supply; or when the low-temperature section heat supply and high-temperature section heat supply of the heated medium are satisfied at the same time, the heating temperature difference in the low-temperature section is large, and the high-performance index absorption heat pump process is often not used at this time, resulting in Waste heat utilization rate is not high

The invention provides a multi-end heat supply first kind absorption type heat pump and belongs to the technical fields of afterheat utilization and heat pumps. The multi-end heat supply first kind absorption type heat pump mainly consists of a generator, a first absorber, a second absorber, an absorption evaporator, a condenser, an evaporator, a throttling valve, a refrigerant liquid pump, a first solution pump, a second solution pump, a first solution heat exchanger and a second solution heat exchanger, wherein the second absorber provides solution for the generator, the generator provides solution for the first absorber, the first absorber provides solution for the absorption evaporator, the absorption evaporator provides solution for the second absorber, the generator provides refrigerant steam for the condenser, the condenser provides refrigerant liquid for the evaporator, the evaporator respectively provides refrigerant steam for the first absorber and the absorption evaporator, the evaporator provides refrigerant liquid for the absorption evaporator and absorbs heat to form refrigerant steam to be provided for the second absorber, and the first absorber, the condenser and the second absorber supply heat, and thus the multi-end heat supply first kind absorption type heat pump is formed.
Description
Technical field: [0001] The invention belongs to the technical field of low-temperature waste heat utilization and heat pump / refrigeration. Background technique: [0002] In the field where the first type of absorption heat pump technology is used to realize waste heat utilization, when the temperature range of the heated medium is wide, the absorption heat pump process that uses the two heat supply ends of the associated absorber and condenser to complete the heat supply is often There are certain limitations. Its performance is that in an absorption heat pump process, the heat supply temperature of the associated absorber and condenser is similar, and its heat supply often cannot satisfy the low-temperature section of the heated medium at the same time under the premise of a reasonable temperature difference. and high-temperature section heating; or when the low-temperature section heating and high-temperature section heating of the heated medium are satisfied at the same...
