For example, in step S321, if the supply temperature value T2 measured at 0:00 is 15 degrees and the room temperature value T1 is 15 degrees when the predetermined time interval is 10 minutes, the supply-indoor temperature difference value? The supply-indoor temperature difference value? T12 is 5 degrees when the supply temperature value T2 measured at 0:10 is 20 degrees and the room temperature value T1 is 15 degrees, The supply-indoor temperature difference value? T12 may be 21 degrees when the measured supply temperature value T2 is 42 degrees and the indoor temperature value T1 is 21 degrees.

The step S323 may refer to a step in which the operation determination unit 120 determines a time period in which the supply-indoor temperature difference value? T12 is greater than a predetermined operation threshold value as a time period during which the air conditioner 10 operates.

In the above-described example, if the operation threshold value is 10 degrees, for example, step S323 will be described. The supply-indoor temperature difference value? T12 at 0:00 is 0 degree, and the supply- The value ΔT12 is 5 degrees and the supply-indoor temperature difference value ΔT12 at 0:20 is 21 degrees. Therefore, in step S323, the operation determining unit 120 determines the temperature of the air conditioner from 0:00 to 0:10, It is determined that the time period during which the air conditioner 10 does not operate is determined as a time period during which the air conditioner 10 does not operate from 0:10 to 0:20 and from 0:20 to 0:30, Can be judged as a time period in which the mobile terminal operates.

If the difference between the room temperature T1 and the supply temperature T2 is small, it means that the cooling / heating unit 10 does not operate. On the contrary, if the room temperature T1 and the supply temperature T2 ) Is large, it means that the cooling / heating unit 10 is operating.

Meanwhile, in the above-described example, when the operation threshold value is 10 degrees, the method of calculating the energy exchange amount of the cooling / heating apparatus according to the embodiment of the present invention may set various operation threshold values as necessary in addition to the above- , The present invention is not limited to a specific operation threshold value.

Now, with reference to FIGS. 3 and 5, step S330 will be described.

5 is a flowchart for explaining a step of calculating an energy exchange amount of a cooling / heating apparatus in a method of calculating an energy exchange amount of a cooling / heating apparatus according to an embodiment of the present invention.

In step S330, the energy exchange amount calculating unit 130 calculates an energy exchange amount of the cooling / heating unit 10 based on the difference between the room temperature value T1 and the coil temperature value T3 for each time period during which the cooling / Quot; is calculated.

5, in operation S330, the indoor-coil temperature difference value calculation step S331, the energy exchange performance deterioration coefficient selection step S333, and the energy exchange performance degradation coefficient are multiplied by the interval energy exchange capacity, (S335). ≪ / RTI >

In step S331, the energy exchange amount calculation unit 130 calculates the indoor-coil temperature difference value? T13, which is a difference value between the room temperature value T1 and the coil temperature value T3, .

For example, in step S331, if the indoor temperature value T1 measured at 0:00 is 15 degrees and the coil temperature value T3 is 17 degrees when the preset time interval is 10 minutes, the indoor-coil temperature difference value? The indoor-coil temperature difference value? T13 is 30 degrees when the indoor temperature value T1 measured at 0:10 is 15 degrees and the coil temperature value T3 is 45 degrees, The indoor-coil temperature difference value T13 may be 44 degrees when the measured indoor temperature T1 is 21 degrees and the coil temperature value T3 is 65 degrees.

In step S333, the energy exchange rate calculation unit 130 calculates an energy exchange performance degradation coefficient (? T13) corresponding to the indoor-coil temperature difference value? T13 by matching the indoor-coil temperature difference value? May be selected for each predetermined time interval.

At this time, the energy exchange performance degradation rate table is a table showing the energy exchange performance degradation coefficient and the indoor-coil temperature difference value? T13, which are coefficients indicating the degree of degradation of the energy exchange performance of the cooling and heating apparatus 10 according to the indoor- Can be referred to as a matching table.

Here, the energy exchange performance degradation coefficient may be a proportional coefficient that decreases linearly or nonlinearly as the indoor-coil temperature difference value? T13 decreases.

That is, the greater the difference between the room temperature value T1 and the coil temperature value T3, the better the performance of the cooling / heating unit 10 and the smaller the difference between the room temperature value T1 and the coil temperature value T3 The performance of the cooling / heating unit 10 may indicate a bad state.

Hereinafter, a more detailed description of the energy exchange performance degradation rate table will be described later with reference to FIGS. 6B and 7B, and redundant description will be omitted.

In step S335, the energy exchange rate calculation unit 130 multiplies the energy exchange capacity of the zone energy exchange capacity for each of the time zones in which the cooling / heating unit 10 operates, by the energy exchange performance degradation coefficient, The amount of energy exchanged by the heat exchanger may be calculated.

At this time, the time period during which the cooling / heating unit 10 operates may be determined according to the determination result in step S320.

For example, the interval energy exchange capacity can be calculated based on the ratio of the rated capacity and the predetermined time interval representing the energy exchange capacity per hour of the air conditioner 10.

For example, the rated capacity is a capacity indicating the amount of energy that the air conditioner 10 can exchange per hour, and the unit may be expressed in kcal / hour.

For example, if the predetermined time interval is 10 minutes, the interval energy exchange capacity may be a capacity obtained by dividing the rated capacity by 6, which is a capacity converted into a 10-minute unit of 1 hour (60 minutes), which is the time unit of the rated capacity.

For example, if the rated capacity is 6000 kcal / hour and the predetermined time interval is 10 minutes, the interval energy exchange capacity may mean 1000 kcal / 10 min.

For example, if the interval energy exchange capacity for a specific time period during which the air conditioner 10 is operating is 1000 kcal / 10 min and the energy exchange performance deterioration coefficient is 0.7 in step S335, the air conditioner 10 10) can be 7000 kcal.

According to one embodiment, when the air conditioner 10 is a radiator, the amount of energy exchange may be an amount of energy supplied by the radiator to the room. If the air conditioner 10 is a radiator, It can mean energy removal.

For example, although not shown in the drawings, the method for calculating the energy exchange amount of an air conditioner according to the embodiment of the present invention may further include a step of calculating a daily energy exchange amount (not shown).

For example, in the step of calculating the daily energy exchange amount (not shown), the energy exchange amount calculating unit 130 calculates the energy exchange amount of the cooling / heating unit 10 for each time period in which the cooling / and the daily energy exchange amount of the cooling / heating unit 10 may be calculated.

For example, if the preset time interval is 10 minutes, a day can be divided into 144 time intervals, and in the step of calculating the daily energy exchange amount (not shown), the energy exchange amount calculation unit 130 calculates a total of 144 The amount of energy exchange with respect to the time period during which the cooling / heating unit 10 operates during the time interval can be added up to calculate the daily energy exchange amount.

Now, referring to Figs. 6A and 6B, a method and an apparatus for calculating the energy exchange amount of a cooling / heating apparatus according to an embodiment of the present invention will be described in the case where the cooling / heating unit 10 is a radiator.

6A and 6B are views for explaining a case where the cooling and heating apparatus is a radiator in the method and apparatus for calculating the energy exchange amount of an air conditioner according to an embodiment of the present invention.

As shown in FIG. 6A, a case where the air conditioner 10 is a radiator is exemplified by taking a case where a preset time interval is 10 minutes and a rated capacity is 6000 kcal / hour.

In step S310, the temperature value receiving unit 110 may receive the room temperature value T1, the supply temperature value T2, and the coil temperature value T3. For example, when the case is 0:20, The value T1 may be 21 degrees, the supply temperature value T2 may be 42 degrees, and the coil temperature value T3 may be 65 degrees.

In step S321, the operation determining unit 120 can calculate the supply-indoor temperature difference value? T12, which is a difference value between the indoor temperature value T1 and the supply temperature value T2, For example, the supply-indoor temperature difference value? T12 may be 21 degrees.

In step S323, the operation determination unit 120 may determine that the time interval during which the supply-indoor temperature difference value? T12 is greater than the predetermined operation threshold value is the time during which the air conditioner 10 operates. If the operation threshold value is 10 For example, when the time interval from 0:20 to 0:30 is taken as an example, the supply-indoor temperature difference value (ΔT12) at 0:20 is larger than the operation threshold value (21 degrees) of 21 degrees, The time interval from 20 minutes to 0:30 may be determined as a time interval during which the air conditioner 10 operates.

In step S331, the energy exchange amount calculation unit 130 may calculate the indoor-coil temperature difference value? T13, which is a difference value between the room temperature value T1 and the coil temperature value T3, For example, the indoor-coil temperature difference value? T13 may be 44 degrees.

In step S333, the energy exchange rate calculation unit 130 may select the energy exchange performance degradation coefficient by matching the indoor-coil temperature difference value? T13 to the energy exchange performance degradation rate table as shown in FIG. 6B, The indoor-coil temperature difference value? T13 is 44 degrees. Therefore, the indoor-to-coil temperature difference value? T13 shown in FIG. 6B is included in the interval of? 40 or more, Can be selected to be 0.9.

In step S335, the energy exchange amount calculation unit 130 multiplies the interval energy exchange capacity (1000 kcal / 10 min), which is the capacity obtained by dividing the rated capacity (6000 kcal / hour) by 6, The supply amount can be calculated. As an example, at 0:20, since the energy conversion performance degradation coefficient is 0.9, the amount of energy supplied by the radiator to the room from 0:20 to 0:30 is 900 kcal Can be calculated.

Now, referring to Figs. 7A and 7B, a method and apparatus for calculating the energy exchange amount of a cooling / heating apparatus according to an embodiment of the present invention in a case where the cooling / heating unit 10 is a cooling unit will be described.

7A and 7B are views for explaining a case where the cooling and heating apparatus is a cooling unit in the method and apparatus for calculating the energy exchange amount of a cooling and heating apparatus according to an embodiment of the present invention.

As shown in FIG. 7A, the case where the predetermined time interval is 10 minutes and the rated capacity is 5400 kcal / hour is taken as an example, and the cooling / heating unit 10 is a cooling unit.

In step S310, the temperature value receiving unit 110 may receive the room temperature value T1, the supply temperature value T2, and the coil temperature value T3. For example, when the case is 0:40, The value T1 may be 26 degrees, the supply temperature value T2 may be 10 degrees, and the coil temperature value T3 may be 5 degrees.

In operation S321, the operation determination unit 120 may calculate the supply-indoor temperature difference value? T12, which is a difference value between the indoor temperature value T1 and the supply temperature value T2, For example, the supply-indoor temperature difference value? T12 may be 16 degrees.

In step S323, the operation determination unit 120 may determine that the time interval during which the supply-indoor temperature difference value? T12 is greater than the predetermined operation threshold value is the time during which the air conditioner 10 operates. If the operation threshold value is 10 For example, when the time interval from 0:40 to 0:50 is taken as an example, the supply-indoor temperature difference value (ΔT12) at 0:40 is greater than the 16-degree operation threshold value (10 °) The time interval from 40 minutes to 0:50 may be determined as a time interval during which the air conditioner 10 operates.

In step S331, the energy exchange amount calculation unit 130 can calculate the indoor-coil temperature difference value? T13, which is a difference value between the room temperature value T1 and the coil temperature value T3, For example, the indoor-coil temperature difference value? T13 may be 21 degrees.

In step S333, the energy exchange amount calculating unit 130 may select the energy exchange performance degradation coefficient by matching the indoor-coil temperature difference value? T13 to the energy exchange performance degradation rate table as shown in FIG. 7B, The indoor-coil temperature difference value? T13 is 21 degrees, so that the indoor-coil temperature difference value? T13 shown in FIG. 7B is included in the interval of? 20 or more, Can be selected to be 0.9.

In step S335, the energy exchange amount calculating unit 130 multiplies the interval energy exchange capacity (900 kcal / 10 min), which is the capacity obtained by dividing the rated capacity (5400 kcal / hour) by 6, If the energy supply degradation coefficient is 0.9, the amount of energy removed from the room by the cooler from 0:40 to 0:50 is 810 kcal Can be calculated.
