PURPOSE:To facilitate wiring and to reduce installation cost by arranging W.H.M. in each group of air-conditioner in order to measure W.H. of each group then obtaining W.H. of each air-conditioner through proportional division of group W.H. by the accumulated value of current of each air-conditioner. CONSTITUTION:Air-conditioners 2a, 2b, 2c are classified into three groups (a), (b), (c), provided with W.M.s 1a, 1b, 1c associated with pulse transmitters for transmitting pulses through a controller 3a to a master unit 4, and the pulses are accumulated in a personal computer 5. Current values of the air-conditioners 2a, 2b, 2c are transmitted through a transmission controller 3b to the master unit 4 then they are converted into power values through the personal computer 5 and accumulated therein. W.H. values of the air-conditioners 2a, 2b, 2c are obtained through proportional division of group W.H.M. by a W.H.M. value of an air-conditioner belonging to the group obtained based on the current thereof. |
