Claim 3:
4. The variable refrigerant flow system of claim 3,
wherein the variable refrigerant flow management system is further configured to apportion a share of the outdoor unit consumption measurement to the first outdoor unit based on the activation requests by:
determining a compressor run time of the first outdoor unit;
determining a compressor total frequency based at least on the compressor request frequencies of the activation requests received by the first outdoor unit;
calculating a consumption factor of the first outdoor unit based at least on the average compressor total frequency and the compressor run time;
calculating a power proportional index for the first outdoor unit by dividing the consumption factor of the first outdoor unit by a sum of consumption factors of the one or more additional outdoor units and the consumption factor of the first outdoor unit; and
multiplying the outdoor unit consumption measurement by the power proportional index.
