Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an air conditioner consumption integration device used for each unit of an apartment complex or the like.

Conventional technology In multifamily housing such as condominiums, all units share a heat source such as a boiler or chilling unit, and each unit selects an indoor unit such as a fan coil unit with a heating and cooling capacity that matches the heating and cooling load of each room. A so-called central heating and cooling system is often used.

In such a system, the cost of operating the heat source is
Each household must share the cost, but if it is distributed equally,
Because the difference in frequency of use would lead to unfairness, the method shown in Figure 3 was adopted.

That is, fan coil units 7) 91° 92.93 with different cooling and heating capacities are installed in each B3. Power line 8
1 through integrated power meters 86, 87, and 88. Further, the heat sources 89 and 90 were also connected to the commercial power source 81 by an integrated power meter 91.

With this configuration, each house has two fan coils (22)91.
If you use 92.93, the integrated power meter will be 86.87.8
8 is activated and the fan coil of the terminal is uniso) 91.92.9
The amount of electricity used in step 3 is displayed for each house. On the other hand, boiler 8
9 and chilling unit) 90, the costs of electricity and fuel such as city gas, which are displayed on the integrated power meter 94, are incurred, but these costs must be shared among each household. In this case, a method was adopted in which the cost required for the heat source was divided proportionally based on the amount of power used that was displayed on the integrated power meter installed in each house.

Problems to be Solved by the Invention By the way, the operating cost of a heat source is considered to be approximately proportional to the amount of heat generated by the heat source, that is, the amount of heat used in each house. If the amount of electricity used by the fan coil unit and the amount of heat used by each unit are not proportional, the cost of the heat source will not be shared fairly.

However, if the relationship between the power consumption and the cooling/heating capacity of fan coils 91, 92, and 93 with different cooling/heating capacities is shown, for example, the relationship is as shown in FIG. 4. There is usually no proportional relationship between power consumption and cooling/heating capacity between Sunawachi, Fan Coil Uni, )91,92゜93, and generally speaking, the higher the capacity of the model, the lower the power consumption. tend to lack ability.

In the conventional method, each model of fan coil unit 7) with different ratios of cooling/heating capacity and power consumption approximates that shown by solid line A in Fig. 4, and is above solid line A. For model 91, the shared cost was relatively low relative to the amount of heat used, and conversely, for models 92 and 93 below the solid line A, it was relatively expensive.

Therefore, for example, if the fan coil unit 91 is used more frequently in door 83, and the fan coil unit 93 is used more frequently in doors 84 and 85, there will be an unfair cost sharing between door 83 and 84, 86. There was a problem.

The present invention solves these problems, and aims to provide an air conditioner consumption integration device that can measure the amount of heat used in each household and fairly share the operating costs of the heat source. do.

Means for Solving the Problem In order to solve this problem, the present invention provides an indoor unit with a setting notch detection section for detecting the setting notch of the fan motor, and a model setting section for setting the model of the indoor unit. and a control section that receives outputs from the setting notch detection section and the model setting section and transmits information on the model and setting notch to the totalizer, and transmits the model and setting notch information transmitted from the indoor unit to the totalizer. an integrating means section that receives the information, integrates the time for each category of the model and setting notch information, and detects a signal every time the sum of these integrated amounts reaches a reference integrated amount; and an integrating means section that receives the output of this integrating means section. The device is equipped with a count section that counts up and displays the count.

Function: With this configuration, the control section determines the model setting and setting notch information based on the signals from the setting notch detection section and the model setting section provided in each indoor unit for each month, and performs the control. The information is outputted from the integrating section to the integrating section, and the time is integrated for each category of cloud type and setting notch information.When the sum of the integrated amounts reaches the standard integrated amount in the integrating means section, the count is increased and outputted to the counting section for counting. It will be displayed.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2. As shown in FIG. 2, each household is equipped with indoor units (11, 12, 13) with different capacities. Each of the indoor units 11, 12, 13 includes a setting notch detection section 14 for detecting the setting notch of the fan motor, a model setting section 15 for setting the model of the indoor unit 11, 12, 13, and a setting notch detecting section 15 for setting the model of the indoor unit 11, 12, 13. A microcomputer (hereinafter referred to as microcomputer) that inputs the output signals of the detection unit 14 and the model setting unit 15 to determine the setting notch and model.
A control section 16 consisting of the following is provided. This indoor unice) 1
1, 12, and 13, each unit is equipped with one totalizer 60, and this totalizer 60 determines the model and setting notch based on the signal from the control section 16, and determines the model and setting notch for each indoor unit 11.
12.13 setting notch and an integrating means section 17 which receives model information and integrates this information over time for each category, and a counter part 18 which receives the output from the integrating means section 17 and counts up. There is.

In FIG. 1, the setting notch detecting section 14 is connected between a fan motor 19 and a notch changeover switch 23 having a strong contact 20, a middle contact 21, and a weak contact 22 for switching the notch of the fan motor 19. The primary side 27°28.29 of a nine-pin coupler is connected with diodes 24,25,26 connected in antiparallel. The common side of the notch changeover switch 23 is connected to the power supply 3Q. The control section 16 includes three of the model setting sections 15.
Switch 3 connected to each input port of the bit
1, 32, and 33, and the combination of these switches 31, 32! The model of the indoor unit 11, 12, and 13 is set and input to the control section 16. Along with this, the secondary sides 27a, 28a, 2 of the photo coupler
For example, by operating the strong contact 20, the transistor on the secondary side 27a of the photocoupler is turned on and inputted to the control section 16, and when it is at L level, a strong notch is determined. In the integrating unit 17 of the totalizing meter 50, the output from the control unit 16 is connected to the input of an AND circuit 36 via a photocoupler 34, and one side of the AND circuit 36 is connected to the integrating unit 36 consisting of a microcomputer. In addition, it is connected to the integrating section 36 via a driver circuit 37 which is turned on and off by the output from the AND circuit 36.

The integration unit 36 calculates the time for each category of indoor unit information based on the setting notch and model information transmitted from the control unit 16, and determines when the total amount of integration reaches the reference integration amount. Then, due to the L level output from the driver circuit 38, a current flows through the relay coil 39 and the relay contact 39a is turned on, so that the electromagnetic counter 41 connected to the power source 4o counts up for each reference integrated amount.

In the above configuration, for example, the indoor unit 1 with a certain capacity
1 as an example, the notch can be switched freely, but if the strong contact point 2o is operated, the fan motor 19 is operated in strong wind through the primary side 27 of the photocoupler. At this time, the secondary side 27a of the photocoupler Then, the transistor is turned on and an L level signal is input to the control section 16.

On the other hand, the model setting section 15 encodes the model of this indoor unit, sets it with each switch 31 to 33, and inputs it to the control section 16. This model and setting input, the notch input of the fan motor 14, that is, the input boat level of each notch, the 3-bit input capo eFI that sets the model of the indoor unit 11, and the information of the result determined by the minute control unit 16. is encoded and output to the photocoupler 34 as serial data. This serial data is inputted to the AND circuit 35 via the photocoupler 34, and a gate signal that becomes H level only when sampling the serial data of the indoor unit 11 from the integration means section 36 is inputted to the other side of the AND circuit 35. The output is output to the driver 37 via the AND circuit 35, and when it is at H level, the driver 37 is turned ON, and the information is input to the integration means section 36, and the output based on the notch and model setting information from the control section 16 and the indoor unit 11 are output. The usage time, that is, the time integration is integrated by the integration means section 36. The above inputs are integrated by the integration means section 36,
When a certain value, that is, the sum of the integrated amounts reaches the reference integrated amount, the driver circuit 38 is turned on by outputting an H level to the driver circuit 38, current flows through the relay coil 39, and the relay contact 39a is turned on. An electromagnetic counter 41 connected to a power source 40 counts up and displays the value.

We have provided an integration unit that integrates time, and when the total amount of integration reaches the standard integration amount, it is output to the counting unit, so the notch can be switched freely in indoor units with different capacities. Even if a change is made, the notch switching detection section accurately transmits the information to the control section, and the model setting section determines the model and transmits it to the totalizer, which counts and amps the operating time of the indoor unit, and displays the amount of heat used. The usage amount of the air conditioner for each month is displayed in terms of the amount of heat used, which has the effect of fairly sharing the operating costs of the heat source.
