Abstract

The seasonal performances, accounting for steady state conditions and on/off cycling losses, of a conventional fixed speed, a two speed, and a variable speed vapour compression heat pump have been determined for the annual heating demand of a large detached house. An economic analysis of the energy savings shows that, compared with a conventional fixed speed heat pump, the two speed, simple variable speed, and microprocessor-controlled heat pumps have pay-back periods of two, six and five years respectively.
