Description

  The present invention relates to a facility energy billing system and a facility energy billing method, and in particular, a facility energy billing system for billing each tenant for use of facility energy of a plurality of tenants sharing a watt-hour meter indicating the amount of facility energy used. The present invention relates to a facility energy billing method.

  When a plurality of tenants are occupying each room or floor in a building, for example, each tenant may share one watt-hour meter for use of equipment such as an air conditioner. In this case, the air conditioning energy usage amount of the air conditioner used by each tenant has been adopted as a system that apportions the air conditioning energy usage amount measured by the watt hour meter by the integrated value of the operating time of each tenant air conditioning device.

  In addition, for normal working hours, each tenant is generally billed for the air-conditioning energy usage together with the rent. On the other hand, the amount of air-conditioning energy used after working hours is often charged separately. The amount of air-conditioning energy generated after working hours varies depending on the tenant when there are tenants operating at night or depending on the number of employees who work overtime.

  Furthermore, the air conditioner may be used in response to a command from the central management room for an air conditioner operation test at a time other than the working hours.

  On the other hand, Patent Document 1 discloses an overtime air-conditioning charge billing system that prevents overcharging for a tenant when a plurality of tenants share one air conditioner. Here, each tenant's final exit time from the entrance / exit management system, the start time and end time of the air conditioning operation results of the air conditioner, and the start time and end time of the overtime air conditioning operation requested from each tenant It is described that an overtime air-conditioning charge for a tenant is determined.

JP-A-6-229611

  According to the method of apportioning the energy consumption of the equipment used by each tenant by dividing the usage amount of the watt hour meter by the integrated value of the operating hours of each tenant's air conditioner, when the tenant uses the air conditioner alone, Since the actual amount of facility energy usage differs from the case where a plurality of tenants use air conditioners at the same time, there is a risk that the billing may not reflect the actual usage of each facility energy. This is a cause of distrust in the facility energy billing system for tenants.

  In addition, since all tenants use air conditioners during normal working hours, the facility energy billing system will not cause much trouble, but the amount of equipment energy generated due to the use of air conditioners etc. outside working hours. As mentioned above, there are cases where troubles occur because each tenant is different. For example, a tenant who is charged for the energy consumption of an air conditioner on a day when he / she does not work overtime, or that the amount of facility energy usage is abnormally biased among tenants who should be using the air conditioner in the same way Troubles due to the illusion and misunderstanding occur frequently.

  Also, when using an air conditioner in response to a command from the central management room for an air conditioner operation test at times other than working hours, the current billing system charges the tenant for the amount of equipment energy used Trouble that occurs.

  An object of the present application is to solve such a problem and to provide a facility energy billing system and a facility energy billing method that accurately reflect the use status of each facility energy for a plurality of tenants who share a watt-hour meter indicating the amount of facility energy used.

Charge amount setting means, and a switch operation output unit that outputs the ON / OFF operation time of the facility switch of each tenant in a predetermined format.

  In addition, in the facility energy billing system, the energy billing amount setting means uses the facility energy usage amount stored in the energy usage amount storage unit in the floor area of each tenant's room during the time period when a plurality of tenants are using the tenant at the same time. It is preferable to set and distribute a predetermined ratio from the normal number of people in the room.

  In addition, in the facility energy billing system, when the energy billing amount setting means is used by a plurality of tenants at the same time, the amount of facility energy stored in the energy consumption storage unit is equally distributed to each tenant. It is preferable to distribute.

  In the facility energy billing system, it is preferable that the energy billing amount setting means sets a billing amount for the amount of facility energy used by each tenant in a time zone after the working hours.

  Furthermore, in the facility energy billing system, the energy usage determination unit excludes the time zone when the facility energy was turned on / off by a command from the central monitoring panel from the history stored in the energy usage status storage unit of each tenant. It is preferable to correct the history.

  In order to achieve the above object, a facility energy billing method according to the present invention is a facility energy billing method for billing each tenant for the use of facility energy of a plurality of tenants sharing a watt-hour meter indicating the amount of facility energy used. Recording a history of the operation of each tenant's equipment switch ON / OFF, storing a history of usage of equipment energy measured by the watt-hour meter, and a history of usage status of equipment energy of each tenant; The step of correcting the history by excluding the time zone when the equipment switch was OFF from the history of usage status, counting the number of tenants using equipment energy based on the corrected history, and multiple tenants In the time zone that was used at the same time, the amount of energy used in that time zone is distributed to each tenant at a predetermined rate and the billing amount is set And steps, characterized in that it comprises the steps of outputting the ON / OFF operation time of the tenant facilities switches in a predetermined format for each predetermined time period.

  In addition, the facility energy billing method can set and distribute a predetermined ratio from the floor area of each tenant's room and the normal number of people in that room during the time period when multiple tenants are using it simultaneously. preferable.

  In addition, in the facility energy billing method, it is preferable to distribute the amount of use of facility energy to each tenant at an equal ratio in a time zone in which a plurality of tenants are simultaneously using.

That is, it is possible to provide a billing system that reflects the actual usage of each facility energy for each tenant. And it is possible to generate a sense of trust in the facility energy billing system of the air conditioner for the tenant.

  As described above, according to the facility energy billing system and the facility energy billing method according to the present invention, each energy usage state is accurately reflected on a plurality of tenants sharing the watt-hour meter indicating the energy usage amount. It becomes possible to charge.

  Hereinafter, embodiments of a facility energy billing system according to the present invention will be described in detail with reference to the drawings.

  1 and 2 show a schematic configuration of one embodiment of a facility energy billing system. In FIG. 1, the relationship between the equipment energy billing system 1 and the apparatus which comprises the air conditioning system 9 is shown. FIG. 2 shows the relationship between the equipment energy billing system 1 and related devices. In the present embodiment, the facility energy billing system 1 will be described by selecting the air conditioning system 9 as the facility. However, the present invention is not limited to the air conditioning system 9 and is similarly applied to other facility systems such as lighting facilities and water supply / drainage facilities. The The facility energy billing system 1 includes a switch operation recording unit 2, an energy usage amount storage unit 3, an energy usage status storage unit 4, an energy usage determination unit 6, an energy billing amount setting unit 7, and a switch operation output unit 5. . An air conditioner 12A and an air conditioner switch 13A are provided in the room of the tenant 10A. The room of the tenant 10B is provided with an air conditioner 12B and an air conditioner switch 13B. The air conditioner 12A and the air conditioner 12B are connected to the outdoor unit 11 to constitute an air conditioning system 9. Although FIG. 1 shows a case where there are two tenants 10 for explanation, the number of tenants is not limited to this.

  In the present embodiment, the facility energy billing system 1 operates only during a time period after a normal office working time period. In other words, the air conditioner ON / OFF is controlled from the central monitoring panel 15 in the normal office working hours. The facility energy billing system 1 operates after the normal office end time and after the air conditioner is turned off from the central monitoring panel 15. And, for example, when the air conditioner 12A or 12B is used by a remnant in the office, or when the air conditioner 12A or 12B is used due to special circumstances such as operating at night, the tenants 10A and 10B used Charges are made for the energy used by the air conditioners 12A and 12B. However, the facility energy billing system 1 may be operated when there is a worker on a holiday or holiday, or when a special event of the company is performed outside the normal office working hours. The facility energy billing system 1 operates in the normal office working hours when an air conditioning system that does not control ON / OFF of the air conditioners 12A and 12B of the tenants 10A and 10B from the central monitoring panel 15 is used. You may let them.

  The switch operation recording unit 2 is an on / off operation time of the air conditioner switches 13A and 13B of the tenants 10A and 10B after the air conditioners 12A and 12B are turned off from the central monitoring panel 15 after the normal office end time. Record the history of. That is, when the air conditioning switches 13A and 13B in the tenant 10A and 10B rooms are turned ON / OFF, the switch operation recording unit 2 receives the ON signal or the OFF signal and records the received time.

  The energy usage amount storage unit 3 records the history of the energy usage amount of the air conditioner measured by the watt-hour meter 14 after the air conditioners 12A and 12B are turned off from the central monitoring panel 15 after the normal office end time. Remember. The energy usage of this air conditioner is the sum of the energy usage of the tenant 10A and the tenant 10B.

  The energy usage status storage unit 4 stores the history of usage status of the air conditioners of the tenants 10A and 10B after the air conditioners 12A and 12B are turned off from the central monitoring panel 15 after the normal office end time. . That is, the history of whether the air conditioners 12A and 12B are in the operating state or in the stopped state regardless of whether the air conditioner switches 13A and 13B in the rooms of the tenants 10A and 10B are ON / OFF A signal indicating the machine ON / OFF information is received and stored.

  The energy usage determination unit 6 excludes the time zone in which the air conditioning switches 13A and 13B are OFF based on the history of the switch operation recording unit 2 from the storage of the energy usage status storage unit 4 of each tenant 10A and 10B. The energy usage status storage unit 4 is made to correct the storage. In other words, the usage history of the air conditioners 12A and 12B recorded in the energy usage status storage unit 4 is other than the usage status due to the ON / OFF of the air conditioning switches 13A and 13B in the rooms of the tenants 10A and 10B. This is because there are factors. For example, when the air conditioners 12A and 12B are turned on / off from the central monitoring panel 15, or for the operation test of the air conditioners 12A and 12B, the air conditioners 12A and 12B are turned on by a command from a central management room (not shown). This is the case. That is, the tenant 10A, 10B is to exclude the time zone when the air conditioner 12 is not turned ON / OFF by itself.

  The energy billing amount setting means 7 measures the number of tenants that use energy for each hour from the storage of the corrected energy usage status storage unit 4, and in a time zone in which a plurality of tenants 10A and 10B are using at the same time. Then, the energy usage amount stored in the energy usage amount storage unit 3 is distributed at a predetermined ratio, and the billing amount for the energy usage of each tenant 10A, 10B is set.

  FIG. 3 shows one example of the usage status of the air conditioners 12A and 12B of the tenants 10A and 10B. FIG. 3 shows signals by ON / OFF of the air conditioner switches 13A and 13B of the air conditioners 12A and 12B. In FIG. 3, the time zone indicated by “AB” indicates the time zone during which both the air conditioners 12A and 12B are operating, and the time zone indicated by “A” is the time zone during which only the air conditioner 12A is operating. The time zone indicated by “B” indicates the time zone during which only the air conditioner 12B is operating, and the time zone indicated by “N” indicates the time zone during which both the air conditioners 12A and 12B are not operating.

  When the air conditioner 12A or the air conditioner 12B is operating alone ("A" or "B" in FIG. 3), the energy billing amount setting means 7 is operating the amount of air conditioning energy during that period. The billing amount for energy use is set as being by the air conditioner 12A or 12B. Further, when the air conditioner 12A or the air conditioner 12B is not operating ("N" in FIG. 3), the energy charge amount setting means 7 does not set the charge amount during that time.

  In the time zone ("AB" in FIG. 3) in which both the air conditioners 12A and 12B are operating, the energy billing amount setting means 7 is a floor of a room used by each tenant 10A and 10B as one embodiment. Distribute in a predetermined proportion from the area and the number of people who normally use the room. That is, the amount of energy used by the air conditioner 12 is related to the volume of the room to be cooled or heated, and the indoor height is often the same for each tenant 10A, 10B. Become. In addition, it is a factor that affects the number of people who normally use the room, which is the main heat source in the room. Therefore, it is possible to distribute the air-conditioning energy usage amount of each tenant 10A, 10B by determining the ratio from these two factors. In another embodiment, the air-conditioning energy usage is distributed to the tenants 10A and 10B at an equal ratio. When the floor area of the room of each tenant 10A, 10B and the number of people who normally use the room are substantially the same, it can be divided equally.

  The switch operation output unit 5 creates the air conditioning energy ON / OFF operation times of the tenants 10A and 10B recorded in the switch operation recording unit 2 in a predetermined format. Further, the electric usage amount of the air conditioning energy set by the energy billing amount setting means 7 is also created in a predetermined format. Then, it is output to the printer 16.

  FIG. 4 shows an example of the format output by the switch operation output unit 5. The time when the tenants 10A and 10B performed the ON / OFF operation of the air conditioning switches 13A and 13B of the air conditioners 12A and 12B is displayed for each date, and the electric usage amount corresponding to the time is displayed. This output table is sent to each tenant 10A, 10B together with the bill for the billing amount, and the amount of electricity used is confirmed.

  Each tenant 10A, 10B can confirm the history of the ON / OFF time of the air conditioners 12A, 12B operated by itself based on this table, and the billing amount accurately reflects the usage status of each air conditioner 12A, 12B. Understand that there is.

  First, it is determined whether or not the normal working hours have ended (S1). If it is before the end time of normal work, this facility energy billing method does not operate. Further, it is determined whether or not the air conditioning is turned off by the central monitoring panel 15 (S2). Even after the end time of normal work, if the air conditioning by the central monitoring panel 15 is ON, this facility energy billing method does not operate. When these two conditions are satisfied, the value of the counter of the watt hour meter 14 is reset (S3), the ON / OFF operation times of the air conditioning switches 13A, 13B of the tenants 10A, 10B are recorded (S4), and the air conditioning The energy usage amount and the air conditioner usage status are stored (S5, S6). Then, it is determined whether or not the normal working hours on the next day have started (S7). If it is before the start time of normal work, this facility energy billing method will not end. Further, it is determined by the central monitoring panel 15 whether or not the air conditioning switches 13A and 13B are turned on (S8). Even after the normal work start time, if the air conditioning by the central monitoring panel 15 is OFF, the facility energy billing method does not end. When these two conditions are satisfied, the facility energy billing method ends, and billing for the amount of air conditioning energy used by the air conditioners 12A and 12B is set for each tenant 10A and 10B (S9 to S14).

  The energy usage status is corrected by excluding the time zone in which the air conditioning switches 13A, 13B are OFF from the usage status of the air conditioning energy of each tenant 10A, 10B (S9). The number of tenants using the air conditioner is measured for each hour from the corrected energy usage status of each tenant 10A, 10B (S10). In the time zone when neither of the tenants 10A and 10B uses the air conditioners 12A and 12B ("N" in FIG. 3), the air conditioning energy usage of each of the air conditioners 12A and 12B is zero (S11). In addition, during the time period ("A" or "B" in FIG. 3) in which one of the tenants 10A and 10B is using the air conditioners 12A and 12B alone, the air conditioning energy of the tenant 10A or 10B used. (S12). Furthermore, in the time zone ("AB" in FIG. 3) in which a plurality of tenants 10A and 10B are simultaneously using, a room in which each tenant 10A and 10B uses the recorded usage amount of air-conditioning energy of the air conditioners 12A and 12B. The floor area and the number of people who normally use the room are distributed at a predetermined ratio (S13). And the charge amount about the usage-amount of the air-conditioning energy of each tenant 10A, 10B is set. Then, the amount of energy used by the air conditioners 12A and 12B on that day is counted and charged over the previous time period (S14).

  FIG. 6 shows a flow of periodically outputting the history of the air conditioning ON / OFF operation time of the air conditioners 12A and 12B and the daily electricity usage. First, it is confirmed whether it is a certain period, for example, the last time of the last day of the month (S15). When it is the last time of the last day of the month, the history of the energy ON / OFF operation time of the air conditioners 12A and 12B of each tenant 10A and 10B and the amount of electricity used for each day are created in the format shown in FIG. (S16). In the output table, the air-conditioning ON / OFF operation time is shown for each date, and the electricity usage corresponding to the time is displayed. This output table is sent to each tenant 10A, 10B together with the bill for the billing amount (S17), and the amount of electricity used is confirmed.

  Each tenant 10A, 10B can confirm the history of the air conditioner ON / OFF time of the air conditioners 12A, 12B operated by itself according to this table, and the billing amount accurately reflects the usage status of each air conditioner 12A, 12B. I understand that.
