# Commission Regulation (EU) No 932/2012 of 3 October 2012 implementing Directive 2009/125/EC of the European Parliament and of the Council with regard to ecodesign requirements for household tumble driers (Text with EEA relevance) (revoked), Division 2: CALCULATION OF THE WEIGHTED CONDENSATION EFFICIENCY

Extent: E+W+S+N.I.
Status: repealed

The condensation efficiency of a programme is the ratio between the mass of moisture condensed and collected in the container of a condenser household tumble drier and the mass of moisture removed from the load by the programme, the latter being the difference between the mass of the wet test load before drying and the mass of the test load after drying. For calculating the weighted condensation efficiency, the average condensation efficiency of the standard cotton programme at both full and partial load is considered.
The weighted condensation efficiency (Ct ) of a programme is calculated as a percentage and rounded to the nearest whole percent as:
Ct=3× Cdry+4× Cdry½∕ 7where:
— Cdry average condensation efficiency of the standard cotton programme at full load,
— Cdry½ average condensation efficiency of the standard cotton programme at partial load.
The average condensation efficiency C is calculated from the condensation efficiencies of test runs and expressed as a percentage:
C=1n−1∑j=2nWwjWi− Wf×100where:
n is the number of test runs, comprising at least four valid test runs for the selected programme,
j is the test run number,
Wwj is the mass of water collected in the condenser reservoir during test run j,
Wi is the mass of the wet test load before drying,
Wf is the mass of the test load after drying.
