National reports
Task 3 - New calculation method for SPF/ Commonly accepted definitions on how SPF is calculated EU SPF (SCOP) acc. To SEPEMO, EU SCOP, EU ERP EU VDI? EU other local standards? US SEER US EER JP AFP China AFP Others??
Task 4 - Identify improvements to existing test procedures
Task 6 Development of an alternative method to evaluate heat pump performance The following operating situations illustrate why SPF alone cannot be judged alone in order to understand heat pump performance: Part load operation in an oversized system (Full load operation in an undersized system) Large share of backup in an undersized system Large share of DHW to space heating (typical for low energy buildings)
T6 - proposals Primary energy ratio PER
T6 - proposals Carnot efficiency The Carnot efficiency is the relation between the efficiency under real conditions and the theoretically maximum reachable efficiency. Drawbacks?
T6 - proposals Specific energy demand The specific energy demand is based on the measured usable energy delivered by the heat pump system to the building, the final energy demand of the heat pump system and heated/cooled building area.
T6 - proposals Heat pump energy supply ratio For bivalent heat pump systems the heat pump energy supply ratio HPESR is calculated to show how much of the usable energy is supplied by heat pump and the backup heater.
Next meeting In conjunction with IEA HPP Conference Montreal, Need to present attractive programme of speakers Will present some of the final draft reports
