Description

 Method for calculating the optimal room temperature by using the measurement amount of each of a plurality of heating and cooling facilities}

 The present invention relates to a method for optimizing the energy used by a building by using the detailed usage of each of a plurality of energy facilities.

Various types of air conditioners used in homes are known, and when various types of air conditioners are used in combination, energy efficiency is known to reduce power consumption. For example, using air conditioners and fans together, rather than using only air conditioners, is known to consume less energy to lower the indoor temperature in summer.

However, there is a lack of research on the ratio of using air conditioners and fans in detail. In other words, it is difficult to identify which of the air conditioners in the home is optimized in terms of energy efficiency.

In particular, since air conditioners are diverse, it is difficult to provide appropriate information using general data and calculation methods, and thus it is very difficult to lower energy consumption of buildings.

Korean Patent No. 10-1448453 proposes a method of predicting and controlling energy of a building in association with weather forecast data. Specifically, after modeling the building energy load, the building is operated according to the optimal energy consumption pattern by simulating various variables using weather forecast data.

Korean Patent No. 10-1653763 attaches various sensors to air conditioners in a building, constructs an automatic control system, and analyzes the gap between the energy consumption detected through the sensor and the simulation result confirmed by the modeling of the building energy load. Propose technology to operate buildings in a narrow way.

In both cases, building energy load modeling is essential. That is, it takes a lot of time and money, but even if it is applicable to large commercial buildings it is difficult to apply to general residential buildings. In addition, if the building energy load modeling itself has an error, the accuracy of the result is reduced, and if the air conditioner is replaced or newly equipped, there is a disadvantage that all steps must be renewed from the modeling construction.

 The present invention has been made to solve the above problems.

 In the following description, "household" refers to the lowest unit consuming energy, and may include unit households in a residential house, a residential assembly building, or a unit division in a business building.

 Hereinafter, "reference temperature unit" refers to a unit for measuring the outdoor temperature or the indoor temperature, and may be, for example, 1 degree Celsius. That is, if the room temperature measured by the sensor is 24.3 degrees Celsius, it may be confirmed as 24 degrees.

 Hereinafter, the present invention will be described in detail with reference to the drawings.

 FIG. 1 illustrates a diagram in which a plurality of households 10 share information by an integrated control unit 500. A single household 10 includes a plurality of air conditioners 200 and each air conditioner 200. A separate power meter 210 is provided on a line connecting the power source to the power supply, so that the current power consumption and the total power consumption can be checked for each air conditioner 200.

Each generation 10 is provided with an outdoor temperature sensor S _out and an indoor temperature sensor S _in . Through this, it is possible to detect the outdoor temperature T _out and the indoor temperature T _in .

In one embodiment of the present invention, each household 10 is equipped with a patient sensor S _n . Through this, it is possible to detect the current number of occupants. In another embodiment, the number of occupants may be directly input by the user through a separate input unit interworking with the control unit 100.

 The controller 100 is provided with an output unit. The output unit is preferably a display method, but is not limited thereto. Through the output unit, an operation result (see FIG. 4) of the method according to the present invention may be output to the user.

 The controller 100 transmits and receives information with a database (not shown). The database stores a plurality of air conditioners 200 and respective energy efficiency. Details thereof will be described later.

 The method according to the present invention will be described in detail with reference to FIGS. 2 and 3.

 The present invention informs the user of the optimal power ratio of the plurality of air conditioners based on the established database, thereby providing information that can reach the desired temperature while reducing energy.

 This section describes how to build a database and how to provide information using it.

First, in order to construct a database, the outdoor temperature T _out and the indoor temperature T _in detected by the outdoor temperature sensor S _out and the indoor temperature sensor S _in the control unit 100 of each generation 10, respectively. Is applied as a reference temperature unit.

In addition, the number of occupants is further applied to the controller 100. The number of occupants to be applied may be detected by the occupant sensor (S _n ) or may be directly input through the input unit.

 In addition, the amount of power used in each of the one or more air conditioners 200 and the plurality of air conditioners 200 currently being operated is applied to the controller 100. The amount of power applied is measured at each wattmeter 210.

 The plurality of air conditioners 200 may use a separate identifier to distinguish each other, or may be directly input by a user. For example, generation 10 has one boiler (A), three electric plates (B1, B2, B3) and two heaters (C1, C2). In the current operation, the air conditioner 200 may recognize that the control unit 100 is one boiler A and two electric plates B2 and B3.

 The controller 100 calculates a total power amount by summing all the applied power amounts.

On the other hand, the control unit 100 sets all the input information, that is, a combination of the outdoor temperature (T _out ), the room temperature (T _in ), the number of occupants and the air conditioner (200) in operation, and the total The amount of power can be set as a "result". In FIG. 2, power amounts of P ₁ to P _n are shown in the plurality of air conditioners 200.

 In this case, a plurality of results are accumulated under the same conditions as time passes, and the total power amount may be confirmed to be the minimum value, and at this time, the ratio of each power amount of the plurality of air conditioners 200 to the optimal power ratio To be stored in the database.

For example, the air conditioner 200 uses one boiler A and two electric plates B2 and B3, and the outdoor temperature T _out is 10 degrees Celsius, the room temperature T _in is 24 degrees Celsius, In the condition that the number of occupants is 3, the data used by the three air conditioners 200 in various ratios will accumulate. The power ratio will be calculated as 80: 15: 5 and stored in the database.

 On the other hand, such a database can be integrated in a number of generations 20.

 That is, the total power amount and the optimal power ratio calculated in each generation are input to the integrated control unit 500, and the integrated control unit 500 selects the minimum total power amount among the plurality of input total power amounts, and the air conditioner 200 corresponding thereto. ) Can be calculated as the optimal power ratio and stored in the database.

 In this case, there is an advantage that the accuracy can be increased to increase the data sample, but there may be a disadvantage that the degree of insulation or ventilation is different for each generation. Therefore, the use of integrated data is preferably made according to user selection.

 Next, a method of providing information using a database constructed with reference to FIG. 3 will be described.

 First, the user inputs the air conditioner 200 to be operated on the control unit 100. The input process may be manual or may be automatically implemented in a manner in which the controller 100 detects the air conditioner 200 in which standby power is maintained.

 Next, the user applies the desired temperature to the controller 100.

The outdoor temperature T _out and the number of occupants detected by the outdoor temperature sensor S _out are further applied to the controller 100. As described above, the number of occupants to be applied here may also be detected by the occupant sensor S _{n or} may be directly input by the user.

Now, all of the information corresponding to the "condition" is applied to the controller 100. That is, the controller 100 estimates the applied desired temperature as the indoor temperature T _in , and thus the combination of the indoor temperature T _in , the outdoor temperature T _out , the number of occupants and the air conditioner 200 is confirmed ( S100, S200).

 Next, it is determined whether to use the integrated data (S300). Not using the integrated data means using only the data measured in the own generation 20, and using the integrated data means using all the data used in the generation 20 as well as the other generation.

 When not using the integrated data (i.e., using only the home data measured in the household, for example), the controller 100 may select an optimal power ratio corresponding to the first generated condition among the data stored in the database. Check and output (S420, S500).

 In this case, it is preferable to output each power ratio of the present air conditioners 200 together. That is, it is to output the data measured in real time in the electricity meter (210).

 4 shows an example of an output screen.

 Consumers having access to the information in FIG. 4 can obtain information that it would be more desirable in terms of energy efficiency to increase the power of the boiler and lower the power of the heater. In other words, it is to induce control by increasing the temperature of the boiler and lowering the desired temperature of the heater.

 Thus, through the method according to the present invention, it is possible to induce energy optimization of various air conditioners in the home.

 In the case of using the integrated data, the condition checked by the control unit 100 is transmitted to the integrated control unit 500, and the integrated control unit 500 checks the optimum power ratio corresponding to the transmitted condition and transmits the result to the control unit 100 again. The optimum power ratio is output (S410, S500).

 In this case, the screen shown in FIG. 4 may be output.

 In another embodiment of the present invention, energy efficiency may be used to calculate an optimal power ratio for the air conditioner 200 without information.

 Specifically, in the database, a plurality of air conditioners 200 and each energy efficiency that has been used in the past is stored, if the air conditioner 200 is inputted to operate the air conditioners not stored in the database, the control unit 100 When the energy efficiency of the air conditioner 200 is inputted to the controller 100, the controller 100 searches for another air conditioner 200 having the same energy efficiency as the input energy efficiency, and estimates the searched air conditioner 200 as the input air conditioner 200. This makes it possible to carry out the method according to the invention.

 In another embodiment of the present invention, when using the integrated data, instead of collecting all data of all generations and comparing them, instead of selecting only “us neighbor” having similar building energy consumption patterns, only the result values identified here It may also be compared (see FIG. 5).

 Various criteria can be applied as a way of determining whether or not a neighborhood is similar. For example, the floor area of the household 20, usage (residential, business), the number of floors, latitude, longitude, etc. may be the reference.

 In the present specification, the present invention has been described with reference to the embodiments shown in the drawings so that those skilled in the art can easily understand and reproduce the present invention, which is merely exemplary, and those skilled in the art can make various modifications and equivalents from the embodiments of the present invention. It will be appreciated that embodiments are possible. Therefore, the protection scope of the present invention will be defined by the claims.
