Details

These reports investigate the effect of cycling on heat pump performance. Both measured and modelled data are used and the effect of cycling on component lifetimes is investigated. The reports conclude that rapid cycling can adversely affect heat pump performance and that heating systems should be designed such that the cycling period is always greater than around 6 minutes.
