Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a configuration diagram showing an embodiment of the present invention. Fig. 1 shows the configuration after renewal. In the figure, on the hoistway 1, the car 211 and the counterweight 2 21 rise and fall. In the lower part of the hoistway 1, a drive unit 231 equipped with a motor, brake and sheave is installed. The basket 2 11 1, the counterweight 2 2 1, and the driving device 2 3 1 are attached to the counterweights 2 5 1 a and 2 5 1 b and the counterweight by the rope 2 14 on the top of the hoistway 1. The pulleys 25 1 c and the pulleys 25 1 d and 25 1 e at the bottom of the car are connected to each other as shown in the figure. Both ends of the mouthpiece 2 14 are attached to the top of the hoistway 1. A control panel 261, which controls the driving device 231, etc., is also installed in the hoistway. As shown in the figure, the elevator equipment including the driving device is installed in the hoistway to form a machine room-less elevator. In the machine room 2 where the driving device and the like were installed before the renewal, a power generator 100 is installed as building equipment. For this reason, the machine room that is no longer required for the overnight drive is being used effectively.

Figure 2 shows the configuration of the elevator equipment before renewal. In the hoistway 1, the car 21 and the counterweight 22 move up and down. A drive device 23 equipped with a motor, brake and sheave is installed in the machine room 2. The cage 21 and the counterweight 22 are connected by a rope 24 via a driving device 23. The two ends of the rope 24 are fixed to the basket 21 and the counterweight 22 respectively. Further, a control panel 26 for controlling the drive device 23 and the like is also installed in the machine room 2. Before the renewal, the elevator is operated by the driving device 23 and the control panel 26 installed in the machine room 2.

Fig. 3 shows the flow of the renewal method from the existing elevator in Fig. 2 to the machine room-less elevator in Fig. 1. According to this flow, the renewal contractor will renew the existing elevator. First, in step A, the existing drive unit and its control panel are unloaded from the machine room to secure space. Next, in Step B, the generator is brought in and installed in the machine room where the space is secured, and the existing elevator is renovated to the machine room less elevator. In the next step C, the installed generator is managed and used for operation control, monitoring of usage and operating conditions, maintenance, inspection, and maintenance. As will be described later, the power generation device can be managed and operated by using the information communication device via the network. The renewal contractor manages and operates the generator set and leases the generator set, and the building owner or the user of the generator set uses the generator set in a rental or lease form. This saves building owners or power plant users the time and expense required to manage and operate the power plant. Furthermore, renting power generation equipment together with the renewal of elevators will increase profitability for renewal contractors. The renovation of the elevator and the installation, management, and operation of the power generator may be performed by different companies, respectively, but in this case, similar benefits are provided to the building owner and the user of the power generator. There is.

In step A of Fig. 3, if there is enough space for installing a power generator in the machine room, either the existing drive unit or control panel can be used. It may be carried out alone, or it may be moved outside the machine room, that is, moved inside the machine room without being carried out. If there is room in the machine room or if the machine room is to be expanded, the existing drive unit and control panel may be left inactive without moving.

As can be seen from Fig. 1, Fig. 2 and Fig. 3, the existing elevator in Fig. 2 will be the machine room-less elevator in Fig. 1 after renewal. Machine room 2 is no longer needed for elevator operation. Therefore, if the existing elevator as shown in Fig. 2 is renewed as a machine room-less elevator, the machine room 2 can be effectively used for purposes other than elevator operation.

In the evening after the renewal in Fig. 1, a generator 100 was installed, and the machine room 2 was effectively used as a generator room. In recent years, power generators have been reduced in size, and some have a capacity that can be installed in the machine room in Elevate. When the power generator is operated during the peak hours of power usage in the building and power is supplied to the building where the elevator is installed, the power of the entire pill is included, including the operating cost of this power generator. Nine charges can be saved. Diesel generators, small gas turbine generators, fuel cells, etc. are used as power generators. Elevator overnight hoistway 1 will be used as a fuel supply pipe to the power generator and a space for wiring from the power generator to the power receiving equipment of the building. If it is difficult to install pipes and wiring in the hoistway 1 for purposes other than elevator operation, create a separate section in the hoistway 1 to create a space separated from the hoistway 1. It may be provided and a pipe or wiring may be passed through the space. If there is another space other than the hoistway 1, it may be used. In addition, when there is waste heat and hot waste water from the power generator 100, these can be used as hot water or used as a cooling and heating source. The management and operation of the power plant in Step C in Fig. 3 This can be done at a monitoring center that monitors remotely. The monitoring center will be operated by an elevator renewal company that will monitor and maintain the elevator as well as install, manage, and operate the generators as well as rehabilitation of the elevators. FIG. 4 shows such an embodiment. In FIG. 4, components having the same reference numerals as those in FIG. 1 indicate the same components. In the monitoring device 320 of the monitoring center 300, not only the elevator status signal from the control panel 261, but also the operating status signal from the power generation device 100 is connected to a wired or wireless network 310. And sends an operation command signal to the power generator 100. The normal operation of the generator 100 is performed by the control unit of the generator 100 itself, but the monitoring center monitors the power usage status and automatically or manually issues commands and selections such as operation modes. it can. In this way, the manager of the building in which the generator 100 is installed does not need to manage or monitor the generator itself. In Fig. 3, the network connecting the control panel 261 and the monitoring device 320 to monitor the elevator itself, and the power generation device 100 and the monitoring device to monitor the power generation device 100 are shown. It can also be used as a network connecting 320.

In the embodiment shown in FIG. 4, the generator 100 is installed by the operator of the monitoring center or by the operator commissioned by the monitoring center, and leased as in the rental system. . The operating state of the generator 100 and the amount of generated power are managed by the monitoring device 320 of the monitoring center 300 through the network 310. The owner or manager of the generator sets the fee by a predetermined method according to the amount of power generated or the operating time of the generator 100, and the person or building that uses the power from the generator 100 Notify the administrator and charge.

Fig. 5 shows the flow of data processing up to billing in the embodiment of Fig. 4. Is shown. In the processing flow 101 in the power generator 100, the generated power is measured, and the cumulative value of the generated power is periodically monitored by the network 310 to the monitoring device 320 in the monitoring center 300. Notify. Processing of the monitoring device 320 When the system is notified, the usage fee is calculated by the calculation method specified for each power generation device, and the power from each customer, that is, the power generation device 100 is used. Notify the owners and building owners of the operating status and usage fees and charge them. In this example, the amount of generated power is measured on the power generation device 100 side, but it can also be performed on the monitoring device 320 on the monitoring center 300 side. In addition, the usage fee is assumed to be proportional to the amount of generated power, but can be calculated according to the operation time. Although the flow in Fig. 5 is only for fee management, the signals required for managing and operating the generator 100, such as the operating status of equipment, safety monitoring, and failure prediction, are also generated. It is exchanged between the device 100 and the monitoring device 320.

The billing method is not only based on the amount of generated electricity, but also based on the ratio of the difference between the electricity bill equivalent to the power consumption of the entire building and the electricity bill actually paid using external power. You may charge. In this way, building owners or users of power generators will focus only on the effective use of the machine room itself, without taking into account the installation costs, management and operation costs of the equipment installed in the machine room. be able to.

In the above embodiment, the elevator monitoring center is operated by a renewal company of Elevator. In other words, monitoring and maintenance of the machine room-less elevator after renewal is performed by a renewal contractor. However, the monitoring center is operated by an elevator monitoring and maintenance company that is separate from the renewal company, and the elevator monitoring and maintenance company may install, monitor, operate, and lease the generator. In any case However, for operators who operate elevator monitoring centers, profitability will be improved by monitoring and maintenance fees for the machine room elevators after renewal and by renting power generation equipment. For building owners and users of power generation equipment, installing a power generation equipment in the machine room will enable efficient use of the machine room after the renewal without spending time on the management and operation of the power generation equipment. I can do it.

As another use mode of the machine room, a power storage device can be installed in the machine room. Examples of the power storage device include a secondary battery and a heat storage device. Power is accumulated from the power receiving equipment in this building during periods of low power usage, and discharged to the building power receiving equipment during peak times of power usage in this building. As in the case of the above-mentioned power generation device, it is possible to save the electricity bill of the whole building.

The power storage device can also store power generated using sunlight or wind power. Fig. 6 shows an embodiment using sunlight. In FIG. 6, components denoted by the same reference numerals as those in FIG. 1 indicate the same components. The photovoltaic power generators 110a, 110b, and 110c are installed on the roof of the building, and the power from them is temporarily stored in the power storage device 120 through the power wiring 121. The photovoltaic power generators 110a, 110b, and 110c may be provided only in the upper part of the machine room 2. By using such a power storage device, it is possible to effectively use natural energy such as sunlight and wind for buildings, and to reduce power bills and contribute to the global environment.

In the above two embodiments, the wiring method between the power storage device and the power receiving equipment, and the management and operation method of the power storage device are the same as those of the power generation device.

The building equipment installed in the machine room after the renewal is not limited to the power supply equipment described above, but may be another building equipment such as an air conditioner.

FIG. 7 shows still another embodiment of the present invention. In this embodiment, the machine The machine room has been converted into a warehouse, which is a building facility. In FIG. 7, the same reference numerals as in FIG. 1 denote the same items. This embodiment is particularly effective when there is room in the machine room. In the example shown in the figure, the car 211 can be operated to the machine room 2 so that luggage can be put in and out of the warehouse 130 installed there. The luggage to the warehouse 130 can be used by the building manager or by the building resident / tenant. The use of the warehouse may be managed by the building manager or by the monitoring center as in the embodiment of FIG. That is, the same management and operation as described in the embodiment of FIG. 4 can be performed. If the height of the machine room 2 is not sufficient and the car 211 cannot operate to the machine room, the luggage may be transported using the stairs that have been installed. Alternatively, a very small cargo-only elevator may be installed to automate access to the warehouse.

One form of renovating the machine room for use in other building facilities is the equipment room for IT (information technology). Buildings that have passed some time after construction may not be sufficiently IT-compatible at this time. The equipment necessary for IT can be installed in the machine room, and the building can be converted to IT to increase added value. As IT-equipment, servers required to use the Internet, etc., and UPS (uninterruptible power supply) to keep the server running even in the event of a power outage are installed. Alternatively, the equipment room for PHS equipment can be used as a mobile radio base station to support wide-area services near the pill. These information devices may be managed by a building manager or by a monitoring center as in FIG. That is, the same management and operation as described in the example of FIG. 4 can be performed.

As a form of refurbishment and use as a further machine room in the machine room, the machine room will be used as a greenhouse for planting flowers. In this case, we ’ll take in the sunlight The machine room may be modified to have windows. Furthermore, the machine room can be effectively used as a rest room for people using the building. This is particularly effective when the building is a commercial building. In this case, it goes without saying that the machine room will be remodeled to be a break room. The machine room can also be used as a storage tank installation room. In other words, secure an emergency water source in the building and install a water storage tank for water countermeasures for effective use. Of course, the water in the water storage tank can be used to supply not only building users but also the general public as drinking water and living water in the event of a disaster.

Fig. 8 shows an embodiment in which the power plant 100 is installed in the machine room 2 as shown in Fig. 1 at the time of renewal, and the height between the top floor and the rooftop of the building is not sufficient. . In FIG. 8, the components denoted by the same reference numerals as those in FIG. 1 indicate the same components. Since such a height is not enough, the top space 711 of the car basket 211 cannot be taken, so that the portion of the floor of the machine room 2 on the hoistway is higher than the other portions. Also in the present embodiment, a power generator 100 is installed in the machine room 2 so that the machine room can be used effectively.

In the above embodiment, the machine room is described as being on the roof. However, the hydraulic elevator may be renewed as a mouth-opening type or a hydraulic-type machine room-less elevator. In this case, the machine room is located outside the roof, for example, underground or downstairs. In this case as well, the machine room can be effectively used in the above-described usage form.

As described above, according to the present invention, the elevator room can be effectively used after the renewal.
