In this paper, the relationship of COP, heating and cooling load and outside air temperature is analyzed using the calorie meter which can carry out temperature adjustment. We constructed “COP Matrix” using the database which is measurement results. APF is calculated from the COP Matrix and compared with catalogue APF to evaluate accuracy of catalogue value. As the result, although the APF of an air conditioner in the catalogue is 5.6, which computed from COP matrix in case1-1 (Tokyo) is 2.9, which is about 0.5 times rather than catalogue value.
