Abstract

The take-up of heat pump technologies in the UK domestic sector has lagged far behind other countries in Europe and North America due primarily to the ready availability of cheap natural gas; this has led to the predominance of gas central heating systems in UK housing. However, with recent gas price volatility along with the depletion of the UK's natural gas reserves interest in heat pump technology, particularly Air source heat pumps (ASHPs) is growing as they have the potential to be a direct, low-carbon replacement for existing gas boiler systems. However, to-date there have been few detailed, simulation-based performance studies of ASHP systems. In this paper a robust, dynamic simulation model of an ASHP device is described. The ASHP model has been integrated into a whole-building model and used to analyse the performance of a retro-fit domestic ASHP heating system. The simulation results were then compared to field trial data.
