2. Description of the Related Art When an air conditioner in a building is operated by electric power supplied from an electric power company, the electricity charge of the consumed electric power is measured by an integrating watt hour meter attached to the power source, Will charge the air conditioner manager a charge for the power usage. The building manager needs to bill the electricity bill charged by the power company according to the usage status of the air conditioner of each tenant in the building. However, when the power supplied to a plurality of air conditioners is measured by an integrating wattmeter and a charge is billed according to the measurement result, one of the plurality of air conditioners has a different unit power price. If you have an air conditioner with a regenerator that uses midnight power or that uses different midnight power to store heat, the amount of electricity used for nighttime electricity and the amount of electricity used for normal electricity It is necessary to separately measure and, and to calculate an electricity charge from the measurement result and each power unit price, and the building manager to charge the electricity charge to each tenant based on the calculation result.
That is, it can be said that it is a fair bill to calculate each electricity rate according to each of the late-night power consumption amount and the normal power consumption amount of each tenant, and to charge based on the calculation result. It was common to collect charges from each tenant based on the calculation result of the charge management device.

Using the valve capacity accumulating means 13 that outputs at each time and the integrated value output by the valve capacity accumulating means 13, the electric energy input to each electric energy measuring means 2a, 2b is proportionally divided for each air conditioning unit. An apportioning means 10 for calculating a ratio, and an electric energy integrating means 4 for accumulating the electric energy for each electric power type for each unit from the apportioning result of the apportioning means, and outputting the integrated result at a predetermined time. The electricity charge unit price storage means 5 for storing the electricity charge unit price according to the type of electric power, the electricity charge selection means 6 for searching and selecting the electricity charge unit price from the electricity charge unit price storage means 5, and the selected electricity charge Unit price multiplied by the electric energy integration means 4 The electricity charge calculation means 7 for calculating the electricity charge for each air conditioning unit from the output electric energy, and the electricity charge for each type of each air conditioning unit calculated by the electricity charge calculation means 7 and the electric energy accumulation means 4 are provided.

Is integrated for T1 time, and the integrated electric energy W1 for T1 time is output to the electric power type determination means 3. However, during normal power, the power meter 53 for midnight is turned off and the power signal is not transmitted. On the other hand, the proportional division ratio is the valve capacity input means 1
2 is calculated based on the product of the opening of each flow rate adjusting valve provided in each indoor unit and each heat storage unit and its rated capacity, and the calculation result is sent to the valve capacity integrating means 13 at every sampling interval time T2. Output. The relationship between the sampling interval time T2 and the integration time T1 is T1> T2,
Moreover, T1 is set to a value that is an integral multiple of T2. Therefore, the valve capacity integrating means 13 converts the output result from the valve capacity input means 12 every T2 hours into the T1 time unit, and calculates the refrigerant flow rate passing through each flow rate adjusting valve at every T1 time. Then, it outputs to the apportioning means 10 every T1 hours.

[0006]

As described above,
Since the air conditioning charge management device with a heat storage device in the conventional air conditioner has the configuration and operation as described above, it has the following problems. 1. The power consumed at midnight is apportioned according to the operating time of each air conditioner operated at midnight, and the midnight power usage charge for each air conditioner is calculated from this apportionment result. It is only necessary to apportion the electricity charges to the indoor units of each air conditioner according to the amount of heat storage used, and multiple indoor units are connected to the air conditioner with a regenerator, and the heat storage consumption of each indoor unit during the daytime. There was a problem that it was an air-conditioning charge management device that was not easy to use and was not suitable for a charge system that had to calculate and charge a late-night power charge based on. 2. In addition, there is a problem that two or more watt hour meters are required to measure the usage amount of the midnight power and the usage amount of the normal power. 3. Further, when the indoor unit is stopped during the integration time T1 which is an integral multiple of the sampling interval time T2, the proportional division ratio is set to 0. Therefore, even if the power consumption W1 is actually measured, the sampling interval If all the indoor units are stopped during the time T2, the above-mentioned measured W1 is inevitably calculated as 0, and the amount charged by the electric power company and each tenant calculated by the charge management device are calculated. There was a problem that the total usage charge did not match. 4. Further, since the heat energy in the heat accumulator stored by the electric power energy cannot be cut off by 100% so as not to dissipate the heat to the outside air, heat dissipation loss occurs during heat storage, and this heat dissipation loss is contained in each room. It must be evenly distributed to the units, but in the conventional distribution of the amount of power used at midnight, when only one indoor unit within the sampling interval T2 is operated, the total use including heat storage heat dissipation loss Electric power is apportioned only to the indoor units that are operating, not to other air conditioners with heat accumulators.
There is a problem that the heat radiation loss during heat storage is unevenly distributed to each air conditioner that uses the heat storage. 5. In addition, when using the air conditioner with a heat accumulator and the air conditioner without a heat accumulator as in the conventional example in a mixed state, the amount charged to each tenant who installed each of these air conditioners In order to measure the fairness, although the electric power using the heat storage energy of the heat accumulator and the electric power used normally other than that are individually calculated and obtained,
When the air conditioner with a heat storage device is operated during the midnight power hours, it is calculated as using the midnight power for heat storage in the conventional technology, so in particular, multiple indoor units are connected to the air conditioner. In that case, there is a problem in that a fee is requested to each tenant user of each indoor unit at an incorrect unit price.

The present invention has been made to solve the above problems. To obtain a highly reliable air conditioning charge management device for an air conditioner that accurately distributes the late-night electricity charge related to the heat storage operation at night according to the operating state of each indoor unit during the day when the heat of the late-night electricity is stored. 2. To obtain an economical air conditioning charge management device that can measure late-night power and normal power with one electricity meter. 3. To obtain a highly reliable air-conditioning charge management device that evenly charges each indoor unit an electricity charge commensurate with the amount of power used by each indoor unit. 4. To obtain a reliable air-conditioning charge management device that allocates accurately considering late-night power due to the heat loss of the heat accumulator. 5. It is an object of the present invention to obtain a highly reliable air conditioning charge management device that calculates the power consumption that meets the user's request.
