A common method for testing and rating of residential HP and AC annual/seasonal performance
In this Annex, the following will be developed:
1) Common calculation methods for SPF using a generalized and transparent approach, based on lab measured data.
2) Establish comprehensive test methods based on further development of existing test standards. The test standards should include test conditions needed for the future SPF calculations.
3) A method to evaluate additional heat pump performance, e.g. Carbon Footprint, Primary Energy Saving or Energy Savings. |

Thermally Driven Heat Pumps for Heating and Cooling
The goal of Annex 34 is to reduce the environmental impact of heating and cooling by the use of thermally driven heat pumps.
The economic, environmental and energy performance of integrated thermally driven heat pumps in cooling and heating systems in a range of climates, countries and applications will be quantified. From this, those areas and applications with the greatest environmental benefit, the best economics and the greatest market potential will be identified. |
