Abstract

PURPOSE:To save energy, by providing each of condominiums with an individual heat balancer that is equipped with a watt-hour meter and can be controlled by the involved tenant, and controlling individually the air condition of divided areas. CONSTITUTION:Each heat belancer 6A is connected with a feeder 17 separated from both a power distributing wire of a centralized air conditioning facility 12 and a power system of the building, and the watt-hour meter 18 is connected with the feeder 17. The integrated value of the watt-hour meter 18 is sent to a centralized control board and a control board 19 of each condominium and is displayed. Each heat balancer 6A is controlled by the control board 19. In case when each tenant divides his room arbitrarily, the room is partitioned by a partition 11 having a temperature sensor 20, and the temperature sensor 20 is connected with the control board 19 and the centralized control board 16. In this case, the installment of the individual heat balancer is specified and the other heat balancers are controlled centrally. According to this arrangement, the energy required for the building as a whole is saved.

Description

[Detailed Description of the Invention] The present invention relates to air conditioning equipment for buildings, and more specifically, building managers and residents can work together to save energy, and as a result, the building as a whole has a large energy saving effect. This relates to air conditioning equipment for buildings that provides the following.

Since the onset of the energy crisis was recognized in Japan, considerable progress has been made in energy conservation in the industrial production sector, but not much progress has been made in energy conservation in the non-production sector, especially in office buildings. Energy conservation efforts in shared buildings, rental buildings, etc. have been slow and have not yielded any results. This is because, as described below, there are problems with the conventional management methods of rental buildings and the configuration of electrical equipment in conventional rental buildings. This problem will be explained below.

In some conventional rental buildings, in addition to central air conditioning equipment that adjusts the temperature of the entire building, there are also small air conditioners called heat balancers that can be operated individually. This heat balancer is arranged along the outer wall of the building, and can be directly operated by a tenant of the building separately from the operation of the central air conditioning equipment. This heat balancer is also connected to the central control panel of the central air conditioning equipment and is configured so that it can be operated remotely from the central control panel. If operation of the heat balancer is permitted, the tenant may operate the heat balancer himself to adjust the temperature of his own room to his preference.

Therefore, in leased buildings where tenants are allowed to operate Heatono (Lancer), the saving of air conditioning energy in the building must be done not only by the building manager but also by the tenants. However, in the conventional electrical equipment of rental buildings, an integrating wattmeter was not installed for each heat balancer, so the power consumption of each heat balancer was hidden in the power consumption of the entire building. As a result, both the pill administrator and the tenant were unable to know the actual state of power consumption in each heat balancer, and no energy savings were made in the heat balancer.

On the other hand, in the conventional management method for rental buildings, the power cost of the heat balancer is mixed in with the power cost of the central air conditioning equipment, added up with other power costs, and then charged to each tenant in proportion to the rent. Therefore, even if a tenant tries to save energy by refraining from operating the heat balancer in his or her room, the fruits of that effort will not be returned to the tenant, and therefore, In the conventional management system for rental buildings, even if building owners and managers request tenants to save energy, the energy saving efforts have essentially come to nothing. In addition, in conventional management methods, the results of energy saving campaigns are not returned to each tenant, so each tenant is not interested in energy saving (particularly air conditioning energy saving), and each tenant is responsible for the temperature distribution of their occupied space. People create living environments with poor air conditioning by creating partitions without considering the above, and in order to improve the situation, they run heat balancers more than necessary, promoting excessive energy consumption. Ta.

The present invention was made in consideration of the above-mentioned actual situation in rental buildings, etc., and the purpose of the present invention is to enable both building managers and tenants to save air conditioning energy, and as a result, to reduce the An object of the present invention is to provide a new building air conditioning system that can make air conditioning energy saving campaigns in buildings, etc. effective. Another object of the present invention is to provide a building air conditioning system that can be applied to existing shared-use buildings and the like.

In the building air conditioning system of the present invention, an integrating wattmeter is connected to a heat balancer that can be controlled individually by the occupants.
Therefore, the amount of electricity consumed by each resident's individual operation is aggregated for each resident, and the cost is borne by each resident.

For this reason, it is not just the building management's fault, but also the tenants.
It is possible to actively participate in the air conditioning energy saving campaign and to obtain the results of the energy saving campaign. In addition, in the equipment of the present invention, a partition plate with a temperature sensor is prepared in case a tenant requests a partition other than the partition υ method specified by the building management in advance. The detected value is displayed on a temperature display device installed in the resident's room, and serves as reference data when the resident controls the heat balancer.

Embodiments of the present invention will be described below with reference to the drawings, but first, problems related to the embodiments of the present invention will be explained.
This will be explained with reference to the figures.

FIG. 1 is a plan view of a room in a rental building equipped with a heat balancer and central air conditioning equipment. In the same figure, 2 is building 1
3 is the wall on the corridor side in the building 1, 4 is a fixed wall that partitions the room 5, 6 is a heat balancer housed in the opening 2a of the outer wall 2, and 7 is on the ceiling of the room 5. Air outlet 8 of a diffuser or anemostat, etc., which is arranged and communicates with the air conditioning duct in the ceiling, 8 is also the ceiling and fixed wall 4
9 is a partition according to a predetermined method. The heat balancer 6 is a small heat pump heating/cooling device, and is configured to cool or heat the outside air taken in through the opening 2a of the outer wall 2 and supply it to the room 5, and is used for the central air conditioning equipment of the building 1. Can be driven individually. In order to maximize the effectiveness of air conditioning, tenants are generally requested to partition the interior of room 5 only in a manner predetermined by the building management. In many cases, partitions other than the conventional partition method are used. In such cases, tenants often install partitions without considering the effectiveness of air conditioning, and as a result, they not only create an environment that is not comfortable to live in, but also become dissatisfied with the performance of the central air conditioning equipment. Otherwise, the heat balancer may be operated more than necessary.

The two-dot chain line in FIG. 1 is a removable partition 1o that was created by the inventor without considering the air conditioning effect. Note that indoor partitions are usually specified so that they are always perpendicular to the window surface, that is, the window-side surface is always included.

If a partition like the one shown by the two-dot chain line in Fig. 1 is made, a section 5a without a lower air outlet on the ceiling surface can be created as shown in the figure.
In addition, a section 5b with a blow-off lower on the ceiling surface is also created. In this case, it would be a waste of air conditioning energy to use this section 5b, for example, as a library or a reference room where no one can enter. On the other hand, if the compartment 5a is used as a room with people, the compartment 5a
The people in room a will feel insufficient cooling or heating, and as a result, the heat balancer 6 that controls the temperature of the room 5 will be operated at a higher output than necessary, resulting in wasted air conditioning energy.

In order to solve these problems, the pill air conditioning system of the present invention is constructed based on the following principles, and is configured to encourage building occupants to save air conditioning energy. There is. That is, in the air conditioning equipment of the present invention,
``The average temperature of the entire building is maintained within the most economical and comfortable temperature range using central air conditioning equipment, but if a resident wishes to have their room at a temperature outside of this temperature range, a heat balancer is required to do so. In principle, electricity costs shall be borne by the resident.

FIG. 2 shows an embodiment of air conditioning equipment for pills according to the present invention. In the figure, 12 is a central air conditioning facility for adjusting the temperature throughout the building. The central air conditioning equipment 12 includes an air conditioner 13 installed in the basement of the building, an ascending tally 14, and a duct 1 on each floor.
5, a blow-off lower, a temperature sensor 8 (FIG. 1), and a central control panel 16° in a central control room, etc., and the air conditioner 13 is controlled from the central control panel 16. In addition, the blowout lower is controlled by the central control panel 1 according to the output signal of the temperature sensor 8.
6 or a temperature sensor 8. The central control panel 16 also serves as a central monitoring panel, and is configured to display the measured values of various sensors belonging to the central air conditioning equipment 12. Each heat balancer 6A is connected to a power supply line 17 that is separate from the power wiring of the central air conditioning equipment 12 and the wiring of other power systems of the pill (for example, lighting system, electric heating system, and water treatment system). An integrated power meter 18 is connected to the power meter 18 . The measured value of the integrated wattmeter 18 is displayed on the display panel of the central control panel 16 via a signal line, and is also transmitted to a small control panel 19 installed in each tenant's room. The control panel 19 is for controlling each heat balancer 6A, and has a temperature display and an integrated power display, but may have a built-in printer. The control panel 19 also includes a heat balancer 6A.
It is also configured to allow the creation of operating programs. A temperature sensor is installed in advance in the partition plate 11 that can arbitrarily partition the inside of each tenant's living room 5, and the output signal of the temperature sensor is a signal connected between the partition plate 11 and the control panel 19. The control panel 19 via the wire
while being input to the central control panel 16 via other signal lines.
It is also transmitted to Furthermore, a temperature display device 21 is installed in each tenant's room 5 to display the detected value of the temperature sensor.

“In addition, in the air conditioning equipment of the present invention, in order to adjust the temperature of the entire pill as much as possible by the central air conditioning equipment 12, it is preferable that only a specific heat balancer be controlled as a tenant, rather than all heat balancers being tenant controllable. Preferably, the remaining heat balancers are configured to be controlled by a central air conditioning facility.
The heat balancer 6A of the embodiment shown in the figure is a Hilde balancer that can be controlled by Tennant (hereinafter referred to as an individual control heat balancer). ) is also installed, although the latter is not shown.

In rental pills equipped with the air conditioning equipment of the present invention as described above, pill management is performed based on the principles described below. In other words, ■ The pill manager uses the central air conditioning equipment 12 to maintain the temperature inside the building within the optimal economic temperature range (for example, around 5°C in the summer, and around 5°C in the winter), but if you want the temperature to be outside this range, you can Adjustments are made using individual control heat balancers 6A belonging to each tenant.

■ Electricity charges for the individually controlled heat balancer 6A shall be borne by each tenant.

■ In principle, the partitioning method for each room is limited to the method specified in advance by the building manager, but if an arbitrary partitioning method is used, the partitioning is done by a partition plate 11 equipped with a temperature sensor as shown in Figure 2. The operating costs and operation of the individual control heat balancer 6A shall be carried out at one's own expense.

Therefore, the tenant side can use the partition υ specified by the building manager.
If the rooms are partitioned according to the system and the living room is used according to the method specified by the building manager, the indoor temperature will reach the optimal economic temperature even if the individual control heat balancer 6A is hardly operated. It is maintained. However, if the tenant installs partitions other than the one specified by the pill administrator, or uses the room in a manner other than the one specified by the pill administrator, the indoor temperature distribution and room temperature may change from the original. If the planned temperature range is exceeded, the individually controlled heat balancer 6At will have to be operated considerably, but the tenant will be responsible for selecting the operating method and bearing the operating costs.

When using a partition other than the one specified by the building manager (for example, as indicated by the two-dot chain line in Figure 1), a partition plate 11 with a temperature sensor head as shown in Figure 2 is used to partition the room. The temperature distribution in the partitioned sections 5a and 5b is determined not only by the control panel 19 of each room but also by the central control panel 16.
It is also displayed in When the tenant operates the individually controlled heat balancer 6A via the control panel 19, the power consumption in the heat balancer 6A is measured by the integrating wattmeter 18, and the measured value is displayed on the control panel 19 and simultaneously displayed on the control panel. In step 19, a print record is created and the power consumption can be known. On the other hand, the measured values from the integrated wattmeter are also transmitted to the central control panel 16 in the central control room and displayed there, so the building manager can also check the usage status of the individually controlled heat balancers for each tenant. By being able to know the temperature distribution, we can advise the tenant to make appropriate changes to the use of heat balancers and partitions, which would significantly worsen the temperature distribution inside the pill.

As described above, in the air conditioning system of the present invention, the increased load and load fluctuations caused by the responsibility of the Tekunto side are absorbed by the individually controlled heat balancer 6A controlled by each tenant. The savings will be directly passed on to the tenants, and as a result, in shared buildings equipped with the air conditioning equipment of the present invention, building managers and tenants will work together to save air conditioning energy. This will bring great results to the energy conservation movement in buildings, which has hitherto been unsuccessful. Note that the shape of the temperature sensor incorporated in the partition plate 11 may be a plate shape or a strip shape, or the control panel 19, the heat balancer 6A, and the integrated power meter 18 may be integrated. Furthermore, a telemeter device may be incorporated into the integrated wattmeter 18 and connected to the rate calculation system of the electric power company.

FIG. 3 shows another embodiment of the present invention, and although a part of the central air conditioning equipment 12 is not depicted in this figure, the central air conditioning equipment is different from the embodiment shown in FIG. 2. It's the same. In this embodiment, the individually controlled heat balancer 6A is configured to be controlled alternately by both the central control panel 16 of the central air conditioning equipment 12 and each tenant.

In the embodiment shown in FIG. 3, a control device n is connected to each individual control heat balancer 6A, and the control device B receives an output signal S1 of a temperature setting device B installed in each tenant's room and a central control panel. 16 temperature setting signals S2 are input. The control device n is composed of a circuit having a comparison function, and the output signal S1 of the temperature setting device B (which represents the set temperature specified by each tenant) is sent to the central control panel 1.
6, when the temperature is within the range of the temperature setting signal S2 (which represents the temperature preset in the central control panel 16), a signal representing the set temperature in the central control panel 16 is individually output as the output signal S3. The output signal S1 of the temperature setting device B is applied to the control heat balancer 6A, but the output signal S1 of the temperature setting device B is applied to the central control panel 1.
6, and if the temperature setting has a higher energy consumption than the temperature setting of the central control panel 16, the output signal S1 of the temperature setting device B is used as the output signal S3. Equal signals are applied to the individually controlled heat balancer 6A. The control device n outputs three types of control signals S4 depending on when the energy consumption of the set temperature in the temperature setting device B is larger than, smaller than, and equal to the energy consumption of the set temperature of the central control panel 16. The control signal is applied to the temperature setting device n and the central control panel 16, and the energy consumption for realizing the temperature range set by the central control panel 16 is equal to the energy consumption for realizing the temperature range set by the temperature setting device n. If it is larger than the consumption, the integrated control panel 16, the integrated power display on the temperature setting device, and the printer are all controlled so that the integrated power display is displayed in blue, and if the reverse is the case, the integrated power display is displayed in red. to control. The temperature setting device 5 is a control panel 19 shown in the embodiment of FIG.
It has the same functions as , and can set the temperature of the heat balancer 6A, as well as a sensor temperature display and an integrated power display. Note that the temperature setting device n and the control device n may be integrated into the individually controlled heat balancer 6A, or the control device 22 may be integrated into the central control panel 16. good. On the other hand, in this embodiment, a temperature sensor and a temperature display device 21 are integrated into the partition plate 11A, so that the temperature on the partition plate can be visually observed.

In the embodiment shown in FIG. 3, if the temperature range set by the tenant deviates from the temperature range set by the central control panel 16, and the energy consumption is lower than the energy consumption set by the central control panel 16, (In other words, during summer cooling, the temperature range set by the tenant is lower than the temperature range set by the central control panel 16, and during winter heating, the temperature range set by the tenant is lower than the temperature range set by the tenant.) is higher than the temperature range set on the central control panel), the control device 22 controls the individual control heat balancer 6A according to the tenant's temperature setting, and at the same time, the control device 22 controls the temperature range of the central control panel 16. A control signal is applied to the temperature setting device n and each integrated power display (not shown).
and determine the display method of the printer. For example, the measured value of the integrated power meter 18 is displayed in red on the integrated power display of the temperature setting device.

On the other hand, when the set temperature range of the tenant is within the set temperature range of the central control panel 16, the signal given from the control device n to the individual control heat balancer 6A is the signal from the central control panel 16. The individually controlled heat balancer 6A is controlled by a centralized control panel 16. In addition, in this case, depending on the control signal given from the control device n to the central control panel 16 and the temperature setting device, the integrated power display and printer of the central control panel 16 and the temperature setting device each display black characters, for example. controlled. Furthermore, when the set temperature of the tenant is outside the set temperature range of the central control panel 16 and the energy consumption thereof is lower than the energy consumption of the temperature range set by the central control board 16, the signal generated from the control device n is This becomes a signal representing the set temperature of the control panel 16, and therefore the individual control heat balancer 6A operates to realize the temperature set by the central control panel 16. In this case, from the control device n to the central control panel 16 and the temperature setting device so that the measured value of the integrated wattmeter 18 is displayed in blue, for example, on the temperature setting device n and the integrated power display and printer of the central control panel 16. A control signal is issued. In such a case, that is, when the air conditioning energy requested by the tenant is lower than that set by the building manager, the individually controlled heat balancer may be operated at the temperature set by the tenant.

Further, in this case, the energy cost that the tenant side has tried to save may be refunded to the tenant by referring to the display record.

In the air conditioning equipment of the present invention shown in FIGS. 2 and 3,
The following two control methods can be implemented as pill air conditioning control methods. In other words, - is the case where the temperature inside the building is always maintained within a constant temperature range by central air conditioning equipment for each season, and the tenant keeps his or her own room at a temperature outside of that temperature range (then This is done using a control heat balancer, and the operation cost of the heat balancer is borne by the user himself/herself.The second method is that the building manager sets in advance the annual maximum energy limit to be supplied to the building, and If a tenant requires a centralized air temperature, the tenant operates an individually controlled heat balancer in their own room to maintain their own room at the desired temperature. The operating costs are the responsibility of the individual.

A more simple explanation of these two methods is as follows. The first control method is based on a system in which the temperature range is determined, but the amount of air conditioning energy supplied is not determined.
In contrast to the second control method, [only the maximum energy supply amount is determined, but the maximum (or minimum) temperature depends on the outside temperature, etc., so it is not always constant during any given period. ” method. In other words, ``In the first control method, the inside of the pill is always maintained within a predetermined temperature range even if the outside temperature becomes abnormally high, so the amount of air conditioning energy supplied changes depending on the outside temperature.''
In contrast, ``In the second control method, the energy limit supplied to the pill is determined, so the temperature inside the building is influenced by the relationship between the amount of remaining energy that can be used and the outside temperature, and even within the same season. The difference is that it fluctuates greatly from day to day. These three methods can be executed in the equipment of the embodiment shown in FIG. 2 by simply changing the program stored in the central control panel 16, but the program for executing the latter method can be used to execute the former method. The program to be prepared for this is also complex, and it is necessary to create a program that takes into account changes in average temperature throughout the year, energy distribution for each season, and changes in the amount of remaining energy from time to time. .

As described above, according to this invention, it is possible to instill an awareness of saving air conditioning energy on the part of the residents in the air conditioning energy saving movement in shared use pills, and it has achieved great results in saving air conditioning energy in pills. can bring
A novel pill air conditioning system is provided. In the illustrated embodiment, the explanation has been given of a rented and shared-use pill, but it goes without saying that the equipment of the present invention can be applied to hotels, apartment complexes, etc., and can also be applied to existing pill air conditioning equipment. is clear.
