Future actions

• IEA Conference workshop programme

• Meeting with CEN standardisation

Partners input

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
