Operating absorption heat pump involves first switching heat source off when switching system off; circulation pumps in absorber-desorber, heating circuits run on for defined period

摘要

The method involves first switching the heat source (19) off when switching the system off; the circulation pump (12) in the absorber-desorber circuit (40) and the circulation pump (46) in the heating circuit (49) continue to run on for a defined period or one that ends as soon as the difference between the return and feed temperatures of the heating system heat exchanger (21) on the absorber-desorber circuit side falls below a threshold value.
