Analysis of heat pump systems using the arsenal research standardised monitoring methodology
The association of Austrian Electricity Companies has funded a project with the aim of developing, testing and evaluating a standardised monitoring methodology for heat pump systems. The results should provide a base for heat pump manufacturers, installers, energy providers, stakeholders and funding agencies. In view of political aspirations particularly in the fi eld of CO2 reduction, the application of renewable energy is a central topic. Heat pumps can thus signifi cantly contribute to a sustainable energy supply. Monitoring was split into three parts: Part 1 included a questionnaire regarding the non-measurable data, Part 2 consisted of a system for continuous data collection and the recording of measured data, while Part 3 included the development of a data base for the administration and evaluation of the measured data. Nine heat pumps were monitored and analysed in the project. For reasons of comparability, only direct-expansion heat pumps were chosen. This report presents the monitoring methodology used in the arsenal research standards. The results of the fi rst measurements - analysis of the seasonal performance factor (SPF), energy costs and TEWI (Total Equivalent Warming Impact) - are described. In addition, there is a comparison of the pollutant emissions which result from the power generation for the operation of the heat pump and the emissions of a gas or oil boiler.
