Branch-cycle first-class absorption type heat pumps, in the arbitrary Branch-cycle first-class absorption type heat pump described in claim 1-16, increase newly-increased absorber, newly-increased choke valve, newly-increased solution heat exchanger, newly-increased solution pump, newly-increased point steam chest, newly-increased condenser and newly-increased evaporimeter, cancel the heated medium pipeline of the second absorber (4) and ft connection, newly-increased absorber (E) has weak solution pipeline through newly-increased solution pump (D), newly-increased solution heat exchanger (C) is communicated with a newly-increased point steam chest (I) with the second absorber (4), newly-increased point steam chest (I) also has concentrated solution to be communicated with newly-increased absorber (E) through newly-increased solution heat exchanger (C), newly-increased point steam chest (I) also has refrigerant steam channel to be communicated with newly-increased condenser (L), newly-increased condenser (L) also has cryogen liquid pipeline to be communicated with newly-increased evaporimeter (K) through newly-increased choke valve (B), newly-increased evaporimeter (K) also has refrigerant steam channel to be communicated with newly-increased absorber (E), newly-increased absorber (E) and newly-increased condenser (L) also have heated medium pipeline and ft connection respectively, newly-increased evaporimeter (K) also has surplus heat medium pipeline and ft connection, form Branch-cycle first-class absorption type heat pump.

38. Branch-cycle first-class absorption type heat pumps, in the arbitrary Branch-cycle first-class absorption type heat pump described in claim 35-37, it is one that evaporimeter (6), the second evaporimeter (7) and newly-increased evaporimeter (K) are closed three, forms Branch-cycle first-class absorption type heat pump.
