Description

Calculating Air-Conditioning Charge of One Household in Apartment}

The present invention relates to a method for calculating the air-conditioning usage fee used in each independent household of a joint building, and more particularly, to determine the use time or power consumption of air-conditioning used by each independent household in a common building using a centralized heating and cooling system. It is a method of calculating the air-conditioning usage fee for each independent household based on the totalization over a period of time.

In general, in large apartments or similar buildings with centralized heating and cooling systems, the entire building uses a centralized cooling and heating system, unlike individual heating and cooling systems. Therefore, in order to reasonably charge the air-conditioning usage fee of each household, it is essential to measure the amount of heat and heat used by each household.

However, in the conventional centralized heating and cooling system, regardless of the amount of heat or time of use, the heating and cooling usage fee of each household is calculated and irrationally imposed on each household, resulting in unnecessary cooling and heating for the user. Eventually, each generation is causing a problem that wastes rather than saving energy by losing awareness of energy.

The present invention was devised to solve the above problems, and measures the use time or power of air-conditioning used in each independent household in a common building such as an apartment using centralized heating and cooling, and based on this, to each independent household. It is an object of the present invention to provide a method for calculating the air-conditioning usage fee used in the independent generation of the joint building of the present invention, which can be reasonably charged.

A step of reading air-conditioning used in each independent household for a predetermined period and inputting the value into a computer; Monitoring and inputting the power used by the centralized air conditioning system of the common building during the predetermined period of time to a computer; And calculating the air-conditioning use fee for a predetermined period of each independent household based on the value read above.

Preferably, the metering in the present invention targets time or power consumption using air-conditioning in each independent generation.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, terms or words used in the present specification and claims should not be construed as being limited to the common or dictionary meanings, and the inventors should properly explain the concept of terms in order to best explain their own invention. Based on the principle that can be defined, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention.

Therefore, the embodiments described in the specification and the drawings shown in the drawings are only the most preferred embodiments of the present invention and do not represent all of the technical idea of the present invention, various equivalents that may be substituted for them at the time of the present application It should be understood that there may be water and variations.

In one embodiment of the present invention in the common building using a centralized cooling system it is possible to determine the cooling used in each independent generation according to the use time. A system for this is shown in FIG. 1.

Referring to the drawings, a cooling system 210, a direct digital controller (DDC) 220, and a computer 230 are installed in the center, and the air conditioner 100 is installed in each independent generation. The solenoid valve 241, the flowmeter 242, and the measuring instrument 244 connected to the solenoid valve 241 are installed in the pipe 240 connecting each generation from the center.

As the cooling system 210, for example, an ice storage system may be used. The ice storage system delivers the cold water to the pipes 240 and delivers them to each generation by freezing the water stored in the ice storage tank at night and melting the ice frozen inside the ice storage tank during the day when the temperature rises. The delivered cold water cools the cold water coil 243, and the independent generation is cooled by the operation of the blower 150. The water heat exchanged in each generation is returned to the ice storage tank.

The solenoid valve 241 controls the supply amount of the cold water supplied to each generation through the pipe 240 connected to each independent generation in the cooling system 210 by the controller 110. The operation time of the solenoid valve 241 is read by the measuring instrument 244 and the operation time is recorded in the DDC 220 through the operation unit 130.

Optionally, the flowmeter 242 maintains a constant amount of cold water supplied to each generation. The computer 230 calculates the total power consumed by the air conditioning system 210 while controlling the operation of the air conditioning system 210. Then, the operation time of the solenoid valve 241 of each independent generation accumulated in the operation unit 130 is recorded in the DDC 220 at predetermined intervals.

The computer 230 determines the cooling fee used in each generation based on the cooling usage time of each generation collected through the DDC 220 and the total power used by the cooling system 210 in operation.

The air conditioner 100 installed in each independent generation includes a controller 110, a temperature sensor 120, a calculation unit 130, and a blower 150.

The temperature sensor 120 is installed in each independent generation, and reads a current room temperature and applies a reading value to the controller 110.

The control unit 110 controls the operation of the solenoid valve 241 and the blower 150.

The blower 150 supplies cold air to the indoors of each generation through the cold water coil 243 based on the command of the controller 110.

The controller 110 operates the solenoid valve 241 and the blower 150 by comparing the room temperature detected by the temperature sensor 120 with a preset temperature according to the operation of the air conditioner 100.

In another embodiment of the present invention, the cooling used in each independent generation in a common building using a centralized cooling system may be determined according to the power consumption of the blower 150. The system for this is shown in FIG. 2. The detailed description of the same configuration using the same member number in comparison with FIG. 1 is omitted.

As can be seen from Figure 1 it can be seen that the cooling is supplied to each independent generation by the operation of the blower 150. Therefore, by calculating the power consumption of the blower, it is possible to calculate the cooling usage fee of each unit household.

In comparison with FIG. 1, the blower 150 is provided with a power meter 140 for reading power consumption of the blower. The meter reading of the power meter is recorded in the DDC 220 through the calculator 130. The blower 150 may operate separately from the cooling operation of each independent generation. Therefore, for more accurate measurement, the power meter 140 is preferably operated in conjunction with the solenoid valve 241 installed in each independent generation.

In addition, the meter 244 shown in FIG. 1 may be additionally installed in addition to the power meter 140. As such, by using the power meter 140 and the meter 244 at the same time to solve the problem caused by any one malfunction, there is an effect that can back up the data.

Similarly, Figure 3 illustrates a heating system constructed by another embodiment of the present invention. Detailed descriptions of the same components having the same member numbers as those in FIGS. 1 and 2 will be omitted.

The hot water supplied through the heating system 310 is supplied to each generation through the tube 240. In the process of supplying the hot water, the supply time of the hot water which is constantly supplied through the solenoid valve 241 and the flowmeter 242 is recorded in the measuring instrument 244 similarly to the cooling system of FIGS. 1 and 2.

The supplied hot water is supplied to each unit household through the hot water distributor 170, and each independent household is heated by heating the panel 180 installed in each independent household. The heat exchanged water is then returned to the heating system through the tube 240.

Figure 4 shows a communication connecting each independent generation and a central computer in a centralized air conditioning system. As shown in FIG. 4, the heating and cooling consumed in each independent generation includes a DDC (through a LAN 410 and a hub 420 connected in a RS-485 or RS-424 manner connecting the computer 230 and each independent generation). 220).

In the first embodiment of the present invention, the usage fee may be calculated according to the cold cooking time. This calculation process is shown in a flowchart in FIG. Similarly, the usage fee in the second embodiment of the present invention may be calculated according to the power consumption of the blower.

With the operation of the air conditioning system, the controller 110 reads the room temperature sensed by the temperature sensor 120 and operates the solenoid valve 241 and the blower 150 to supply cooling hot water to each independent generation to start cooling and heating. S100). And through the measuring instrument 244, the calculating unit 130 integrates the heating and cooling time used in each independent generation (S200).

Optionally, the calculating unit 110 may measure the power consumption of the blower 150. In this case, the calculation unit 130 records the power consumption of the blower 150 through the power meter 140 connected to the blower 150 (S'200). Preferably, the power meter 140 may be configured to operate only when the solenoid valve 241 operates, thereby preventing unnecessary recording due to a malfunction of the blower 150.

Thereafter, the calculating unit 130 accumulates the accumulated power consumption of the blower 150 or the starting time of the solenoid valve, and transmits the accumulated record to the DDC 220.

The DDC 220 records the record in the computer 230 at predetermined intervals. In addition, the power consumed by the heating and cooling system (kwh) is also recorded through the DDC 220 at predetermined intervals (S300).

Accordingly, the computer 230 connected to each independent household through the LAN 410 executes a program for calculating the usage fee of the air conditioner used by each independent household, and the unit calculated by the electric power company for the total power consumption of the heating and cooling system. The total usage fee (P1) is obtained by multiplying the price per power (S400).

In order to charge a usage fee for each independent household according to the time of one embodiment, first, a total usage time P2 of each independent household is obtained. In addition, by dividing the total time (P2) by the use time (P3) of each independent household, multiply the total usage fee (P1) by the heating and cooling usage fee of each independent household is determined.

This can be summarized as (Equation 1) below.

(Equation 1)

Meanwhile, in order to charge a fee for each independent household according to the power consumption of another embodiment, the computer 230 calculates a total usage fee S1 by multiplying the total power consumption of the heating and heating system by the price per unit power calculated by the power company. .

In order to charge a fee for each independent household according to the power consumption of another embodiment, first, the total power consumption S2 of each independent household is obtained. In addition, by dividing the total power S2 by the power consumption S3 of each independent generation, and then multiplying the total usage fee S1, the heating and cooling rates of each independent generation are determined.

This can be summarized as (Equation 2) below.

(Equation 2)

I) Total Power Consumption of Air Conditioning System × Power Charge Per Unit = Total Charge (S1)

II) Air conditioning and heating power of each independent household × quantity of independent households = total electricity consumption (S2)

III) Power of independent generation (S3)

The computer 230 performing the above-described calculation process is illustrated in more detail in FIG. 6.

The DDC 231 receives the value read by the measuring instrument 244 or the power meter 140 through the operation unit 130 and records each independent generation as shown in a table in FIG. 7.

The calling module 232 searches for a corresponding record from the record stored in the DDC 231 according to an operation command of the CPU, and loads the corresponding record into a temporary memory device (not shown).

The calculation module 233 calculates the air-conditioning usage fee for each independent generation by performing any one of the above-described methods based on the reading time or power reading value from the call module 232.

As described above, the calculation module 233 determines the air-conditioning fee used by each independent household by two methods. One is calculated based on the air-conditioning use time of each independent generation read from the meter 140, and the other is calculated based on the power consumption recorded from the power meter 140 operating in conjunction with the solenoid valve 241. Since the operation is as described above, a detailed description thereof will be omitted.

The output module 234 prints the air-conditioning usage fee of each independent generation calculated by the calculation module 233 to a print medium such as paper.

The call module 232, which has begun operation according to the operation instruction of the central processing unit, searches the independent generation database based on the control instruction from the DDC 231 and loads necessary information into the temporary storage element.

Based on the loaded information, the calculation module 233 uses a predetermined time, preferably monthly fee, according to the air-conditioning use time (or power) used by the independent generation based on the above formula (1) or (2). Calculate

The calculated fee is output from the output module 234 to the bill.

According to the method of calculating the air-conditioning fee used in the independent household of the joint building of the present invention, the fee can be charged according to the actual air-conditioning used by each household in the common building where multiple households, such as an apartment, live together. . In addition, each independent generation can check the air-conditioning used by them, so there is an effect that can be alerted by the use of energy.
