Abstract

The aim of this study is to analyze the annual performances of a variable capacity high temperature air source heat pump when retrofitted into a mid-terraced house in different aspects combining control, property ages and locations across the UK. TRNSYS simulations are used to predict the performances of the retrofit high temperature air source heat pump. Firstly, the heat pump model and the whole building model are developed and validated against field trial results. Then, a series of reference dwellings combining three climate conditions (Belfast, Aviemore and Camborne), three dwelling ages (the ‘00s, ‘70s and ‘90s) and two control strategies (fixed water flow temperature and weather compensation) is simulated. The annual simulation results indicate that the heat pump efficiency is highly affected by all three factors. The heat pump’s COPs, energy consumption, running cost and carbon emissions have been discussed in this paper, which can provide good information for further studies assessing the retrofit potential of this kind of heat pump.
