28. the 3rd class absorption heat pumps, in arbitrary the 3rd class absorption heat pump described in claim 25-27, there is weak solution pipeline to be communicated with the second absorber (4) through the second solution heat exchanger (8) to be adjusted into the first absorber (3) to have weak solution pipeline to be communicated with newly-increased generator (A) through newly-increased solution pump (D) and newly-increased solution heat exchanger (C) the first absorber (3), to increase absorber (B) newly has weak solution pipeline to be communicated with newly-increased generator (A) and to be adjusted into newly-increased absorber (B) and to have weak solution pipeline to be communicated with the second absorber (4) through the second solution heat exchanger (8) through newly-increased solution pump (D) and newly-increased solution heat exchanger (C), form compound the 3rd class absorption heat pump on triple effect basis.

29. the 3rd class absorption heat pumps, at claim 15-16, in arbitrary the 3rd class absorption heat pump described in 22-28, increase first flow control valve and second adjustable valve, there are respectively heated medium pipeline and outside connection to be defined as outside and to have heated medium pipeline to be communicated with the second condenser (23) afterwards with the second condenser (23) to have again heated medium pipeline to be communicated with the first condenser (9) through second adjustable valve (25) with outside connected sum through first flow control valve (24) respectively the first condenser (9) and the second condenser (23), the first condenser (9) has heated medium pipeline to be communicated with outside again, form compound the 3rd class absorption heat pump.
