2. on the flow process, when only closing second control valve 6, heated medium flow through successively absorber F2, condenser D2 and newly-increased condenser 1, composite absorption heat pump is according to economic benefits and social benefits and the operation of triple effect complex flow; When only closing control valve 5, heated medium flow through successively absorber F2 and condenser D2, composite absorption heat pump are according to the triple effect process flow operation, and heated medium obtains the heat supply of triple effect heat pump flowsheet; When control valve 5 and second control valve 6 are all opened, all heated mediums flow through successively behind absorber F2 and the condenser D2 its only some again through the control valve 5 newly-increased condenser 1 that continues to flow through, composite absorption heat pump is according to adjustable economic benefits and social benefits and the operation of triple effect complex flow, heated medium obtains the heat supply of economic benefits and social benefits and triple effect combined heat-pump flow process---and the heated medium of second control valve 6 of flowing through obtains the heat supply of triple effect heat pump flowsheet, and the heated medium of the control valve 5 of flowing through obtains the heat supply of combined heat-pump flow process.

The effect that the technology of the present invention can realize---the composite absorption heat pump at economic benefits and social benefits or multiple-effect basis increase high-temperature heat supply end proposed by the invention has following effect and advantage:

1. as heat pump, heat capacity is not or not the time of can remedying simple double effect absorption type heat pump for wider heating range, higher final temperature The defective of foot, performance index is relatively low in the time of can remedying in other words the single-action unit for wider heating range, low initial temperature Defective.

2. can realize the conversion between single-action and double-effect process or economic benefits and social benefits and the triple effect flow process or cooperate, realize energy-saving benefit as far as possible Maximization. Such as, adopt single-action heat pump heat supply flow process during winter higher temperature heat supply, adopt economic benefits and social benefits or multiple-effect system during summer cooling The cold flow journey.

3. the adjusting of unit load and heating parameter be can carry out within the specific limits, load, heat supply temperature excursion are being applied to Bigger occasion can be given full play to two flow processs advantage separately, improves the synthesis energy saving benefit.

4. reduced driving the temperature requirement of thermal medium, this is so that can improve the refrigeration effect of residual heat resources when utilizing utilizing waste heat for refrigeration Benefit, thus the parameter request that reduces driving thermal medium when also being suitable for heat-electricity-cold combined supply is conducive to reasonable energy.

5. increase condenser and choke valve and formed integral type combined heat-pump structure, simple in structure, equipment manufacturing cost is relatively low.
