The invention discloses a household
heat metering method based on a fan coil. The household
heat metering method comprises the following steps that 1, the power PCPU, t of a central air conditioner at the t moment and the
fresh air volume mi, t of an indoor unit at the t moment are obtained; 2, the total
electricity utilization power Pto, t of the central air conditioner at the t moment is calculated; 3, calculating the
power consumption Et, d-e of the central air conditioner from the moment d to the moment e; 4, calculating the
power coefficient Fi, t of the ith indoor unit at the moment t; 5, calculating the power Pin, un, i and t of the ith indoor unit at the moment t under the condition that the corresponding fan coil does not work; 6, the
fresh air power POA, un, i, t of the ith indoor unit at the moment t is calculated; 7, calculating the power Pin, occ, i, t distributed to the outdoor unit at the t moment in the ith indoor unit; 8, calculating the
energy consumption Ein, h, k-> l of the hth indoor unit from the moment k to the moment l; 9, sharing the shared
energy consumption to obtain converted
energy consumption; and 10, counting the indoor units of all the independent areas, and then superposing the corresponding converted energy consumption. According to the invention, fair, just and accurate household metering can be realized.
