【Example】

Example 1. An embodiment of the present invention will be described below with reference to FIG. First, FIG. 1 is a block diagram showing an outline of an air conditioning charge management device of the present invention, and an air conditioning charge management device 8 is composed of a transmission device 9, a control device 10, a setting device 11, and a display 12. The air conditioning charge management device 8 and the centralized control device 2 are connected by a control line 13. The centralized control device 2 includes a power meter 14 with a pulse transmission device, a gas flow meter 18 with a pulse transmission device, a water meter 20 with a pulse transmission device, and a plurality of air conditioners 1 and water heat sources operated by electricity, gas, and water. Machine 19 is connected.

Next, the operation will be described. Setting device 11
Select the power distribution method for each power with. The distribution method for each power is either proportional to the operating time ratio of each indoor unit, proportional to the thermo-on time ratio of each indoor unit, proportional to the operating current amount of each outdoor unit, or proportional to each indoor unit. (Proportion x difference between suction temperature during operation and set temperature), or proportional to (air volume x difference between intake temperature and set temperature) for each indoor unit, or When apportioning the power consumption of the air conditioner, select whether to apportion by the floor area of each tenant. However, in the case of floor area apportionment, the floor area of each tenant is set in the setting device 11.

The information selected by the setting device 11 is transmitted to the centralized control device 2 via the control device 10, the transmission device 9 and the control line 13. The control device 10 calculates the power charge for each power according to the selected proportioning method. Central control device 2
Always measures only the information required for each apportionment method among all air conditioner 1 operating times, thermo-ON times, outdoor unit operating current, suction temperature and set temperature, and air volume, for example, on a daily basis. The data is stored, and the stored data is sent to the control device 10 of the air conditioning charge management device 8 via the control line 13.

It is transmitted to the centralized control device 2. The centralized control device 2 collects necessary information based on the selected information.

First, the electric power value used by all the air conditioners 1 is measured by the electric energy meter 14 with a pulse transmission device. On the other hand, the gas amount used by all the air conditioners 1 is the gas flow meter 18 with the pulse transmission device.
It is measured by. The amount of water supply is measured by a water meter 20 with a pal transmission device. In addition, the operating time of the air conditioner 1 is measured as information necessary for apportioning the electric energy,
The thermo-on time of the air conditioner 1 is measured as information necessary for apportioning the gas amount. For the measured value, data is stored, for example, on a daily basis, and the stored data is further stored in the control line 13.
To the control device 10 of the air conditioning charge management device 8 via.

At the time of calculating the charge, the use charge of each selected tenant is calculated based on the data held by the control device 10. When changing the apportionment method, set device 1 again
1 is selected again. The control device 10 apportions the power used by the air conditioner 1 based on the data obtained from the centralized control device 2 by the apportionment method selected by the setting device 11, and calculates the usage charge for each tenant. By the above, the power usage charge of the air conditioner 1 of each tenant can be calculated for each power, and the proportional distribution accuracy of the usage amount of each power of the air conditioner 1 of each tenant can be increased, and the usage charge can be accurately managed. There is.

The above description has been made for each tenant in which one or more air conditioners 1 are installed, but it is also possible to calculate the usage charge for each air conditioner 1.
