Abstract
Energy consumption by most of the sectors is constantly increasing. In particular, solution to energy conservation of air conditioners is now essential. For evaluation of energy conservation of air conditioners, it is necessary to take into account the variations of outdoor temperature, the heating/cooling load throughout a year and all the operating conditions. But to calculate annual electricity consumption by the current standard, only two found values and other estimated values is used. So I have tested air conditioners, verified the validity of the standard and researched an appropriate way of evaluation of energy conservation.
