なる。In the above prior art, it is not taken into consideration that a heat storage type air conditioning group having a heat storage tank and an air conditioning group having no heat storage tank coexist in the same power meter range. Cannot distinguish between an indoor unit that stores cold heat at low cost at night and uses it during daytime to perform air conditioning, and an indoor unit of an air conditioning group that does not have a heat storage tank. Therefore, the low-priced power consumption required for heat storage is apportioned to the indoor units of the air-conditioning group without the heat storage tank, resulting in unreasonable and inaccurate billing for each tenant.
