In comparison to current test standards, where test modes for fixing the compressor speed are required, a dynamic approach is applied with unfixed compressor speed and thus better reflects the performance of air conditioners under real operating conditions. The dynamic tests are conducted in two calorimeter chambers. The indoor chamber is kept at a constant temperature whereas the outdoor chamber is subjected to a temperature profile based on the climate BIN-distribution, representing the reference cooling demand. The proposed dynamic test considers the dynamic control of an air conditioner and delivers results which could indicate the units' performance in the field.

Heat pumps were tested in line with the EN 14825. The reduction of measurement points, from between five to seven (EN 14825) to only two (two-point-method), leads to 60 % savings in cost and time. It is shown that the shortened method can be used to determine the seasonal energy efficiency of heat pumps with the same degree of precision compared to EN 14825.
