Abstract : The USA have been the leaders in the adoption of seasonal energy effi ciency indices for air-to-air units, in cooling and in heating modes, recently followed by Japan, Korea and China (IPLV for package units). Since seasonal performance indices allow the effect of temperature variations and heating load variations on performance to be included, they are likely to give a better indication of the real effi ciency of the products in the fi eld than do present EER and COP fi gures at full load under rated conditions. At least, this enhances the comparison of the energy performances of different products by taking more variables into account.
