TY - CONF A1 - Palkowski, Carsten A1 - von Schwarzenberg, Stefan A1 - Simo, Anne T1 - Dynamic testing to better reflect real use for the seasonal performance of air conditioners T2 - Refrigeration Science and Technology Proceedings N2 - In this contribution, a dynamic test method to determine the seasonal performance of invertertype air conditioners has been developed and verified. 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.
