CURRENT WORK WITHIN IEA HPP ANNEX 34 ON PERFORMANCE EVALUATION AND TESTING METHODS FOR THERMALLY DRIVEN HEAT PUMPS FOR HEATING AND COOLING


Due to a substantial growth of the market for thermally driven heat pumps (TDHP), a need for standardised performance evaluation became evident among all stakeholders.
Currently, the available standards do not cover all applications of this technology. Therefore, International Energy Agency (IEA) initiated through its Heat Pump Programme (HPP) a
project – Annex 34 “Thermally Driven Heat Pumps for Heating and Cooling” – in which, among other topics, the basis for a standardised testing and performance evaluation of TDHP units and systems should be elaborated. This paper gives an overview of the
proposed concepts for further discussion on standardised testing and monitoring procedures, as well as subsequent performance evaluation of TDHP units and systems.
