EPSRC Case Award: Modelling the performance of Heat Pumps

INTEGRATING HEAT PUMPS INTO SAP MODELLING
Development, validation and application of a domestic heat pump model for space heating and cooling energy.

Overview

The model is intended to bridge the gap between the single Coefficient of Performance parameter currently used in the UK procedures for the assessment of the energy efficiency of dwellings and the dynamic simulation models frequently developed for the academic estimation of heat pump energy use.

Unique Features

The model is responsive to variations in source and sink temperatures while being simple enough to be embedded in a spread sheet model.

The model was developed by:

  • building a regression model, using heat pump performance test results;
  • deriving estimating rules for monthly supply temperature estimates for commonly-used heat pump sources and for demand temperatures;
  • embedding the regression model in the UK standard model for domestic energy estimation, with additional routines to estimate energy consumption for additional heat and for space cooling.

Outcomes / Findings

The model developed was validated by comparison with the existing BREDEM model with the results from the heat pump systems in the monitored dwellings.
