Technical field:

The invention belongs to low temperature exhaust heat and utilize technical field of heat pumps.

Background technology:

In heat pump application; The problem of most critical is how to improve the afterheat utilization rate---concerning first kind absorption heat pump; Improving utilization rate of waste heat means in the reduction of satisfying the driving thermic load that drops under the prerequisite of hot user's request; Concerning second class absorption heat pump, improve utilization rate of waste heat and mean that a certain amount of residual heat resources can provide hot user more effective heat duties.

Concerning second class absorption heat pump, the single-stage unit is compared with one generator two-stage unit, and single-stage unit heat supply temperature is lower but performance index high, is used for the relatively low occasion of hot user's request temperature and can improves utilization rate of waste heat; One generator two-stage unit heat supply temperature height but performance index is low is suitable for the higher relatively occasion of hot user's request temperature; The two is again adjacent on running parameter simultaneously.

See that from the angle of residual heat resources the waste heat medium of higher temperature is used for the low flow process of progression, the waste heat medium of lower temperature is used for the high flow process of progression, and this makes and under the situation that the temperature requirement of heated medium is confirmed, more the degree of depth utilizes residual heat resources.And see that from the angle of performance index though single-stage is adjacent with one generator two-stage running parameter, the performance index difference between the two is bigger.Therefore; As hot user the temperature range broad of---heated medium---, starting stage suitable adopt the single-stage unit then the continuous stage suitable when adopting one generator two-stage unit, adopt single-stage to combine and the compound class II absorption heat pump unit that constitutes can be in the utilization rate that satisfy raising residual heat resources under the prerequisite of hot user's request with the one generator two-stage.Particularly under the less relatively situation of residual heat resources quantity, adopt the combined heat-pump unit can realize effective utilization of residual heat resources and realize better energy-saving benefit.
