Sep. 06, 2007 – Austria – 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 field of CO2 reduction, the application of renewable energy is a central topic. Heat pumps can thus significantly 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.
The 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.
