Method of adjusting indoor temperature

The present invention relates to air conditioning system temperature control, and more particularly to a method of adjusting the indoor temperature to adjust the indoor temperature according to the indoor volume.

The air conditioning system is used to adjust the indoor temperature. In any season, when the air conditioning system is activated, the indoor temperature can be maintained at the set temperature, which provides a comfortable living environment for people. The conventional air conditioning system is used to adjust the indoor temperature by controlling the output temperature of a temperature regulator (such as a cooler or a heater) to maintain the indoor temperature at a set temperature value input by the user. Referring to Figure 1, the most common temperature control method is to keep the indoor temperature continuously at the set temperature value input by the user. The indoor temperature does not change with time until the user changes the set temperature value. In addition, please refer to FIG. 2, and another temperature control mode capable of setting different set temperature values in different time periods, so that the user can input the set temperature value according to living habits, and the air conditioning system controls the temperature adjuster according to different time periods, so that The indoor temperature is maintained at the set temperature value input by the user, so that the indoor temperature is closer to the user's living habits. However, in the above two modes, when the user leaves the indoor space, if the set temperature value is not adjusted to the more energy-saving temperature, the temperature regulator will continue to operate according to the original setting, thus causing energy loss. . Taking cold air as an example, each 1 °C increase will save 6% of electricity. Therefore, if the indoor temperature is automatically adjusted to a more energy-saving temperature without indoor activities, energy consumption can be saved.

The main object of the present invention is to provide a method for adjusting the temperature of a room, which can reduce the waste of energy.

In order to achieve the above object, the method for adjusting the indoor temperature provided by the present invention is combined with a temperature regulator, the method comprising the steps of: detecting the volume of the room; controlling the temperature adjustment when the volume of the room is greater than one decibel. The output temperature of the device is such that the indoor temperature is maintained at a first temperature value; after the indoor volume is less than the decibel value, and after a first set time is maintained, the output temperature of the temperature regulator is controlled to maintain the indoor temperature at A second temperature value.

Through the method of adjusting the indoor temperature, the indoor temperature can be automatically adjusted without affecting the comfort of the user, thereby effectively reducing the unhelpful consumption of energy.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred relationship between indoor temperature, indoor volume and time of a control mode having different first temperature values in different periods in a heating mode.

In order that the present invention may be more clearly described, the preferred embodiments are illustrated in the accompanying drawings. 3 is an air conditioning system applied to a method for adjusting indoor temperature according to a preferred embodiment of the present invention. The air conditioning system includes a temperature setting unit 10, a temperature regulator with a cooler 20 as an example, and a heater. 30 is an example of a temperature regulator.

The temperature setting unit 10 includes an electronic control module 12, a microphone 14 and an input interface 16. The electronic control module 12 is electrically connected to the microphone 14, the cooler 20 and the heater 30 respectively; the microphone 14 is used for detecting the indoor volume; the input interface 16 is for the user to select the air conditioning system to cool the air. The mode or heating mode operates, and a first temperature value T1 and a decibel value dB for input settings (refer to Figure 5). The electronic control module 12 controls the output temperature of the cooler 20 when the user selects the cool air mode; the electronic control module 12 controls the output of the heater 20 when the user selects the heating mode. Out of temperature. The first temperature value T1 refers to a temperature that is expected to be maintained in the room. The decibel value dB is a threshold value set by the user. As a basis for judging whether there is human activity in the room, the microphone 14 detects that the indoor volume is greater than the decibel. When the value is dB, the electronic control module 12 determines that the indoor activity state is present, and when the indoor volume is less than the decibel value dB, the electronic control module 12 determines that the indoor state is no human activity. The user can adjust the decibel value dB according to the background volume of the indoor environment, so that the decibel value is higher than the background volume. For example, in a room adjacent to the road, the decibel value dB is raised to avoid the noisy sound on the road. The control module 12 misjudges.

Hereinafter, the air conditioning system is described as a cooling air mode. The temperature setting unit 10 performs a method for adjusting the indoor temperature as shown in FIG. 4, and the method includes the following steps: the electronic control module 12 controls the output temperature of the cooler 20 In order to maintain the indoor temperature at the first temperature value input by the user.

The electronic control module 12 controls the microphone 14 to continuously detect the indoor volume, and determines whether the indoor volume is greater than or less than the decibel value input by the user.

When the indoor volume is greater than the decibel value, indicating that there is personnel activity in the room, the electronic control module 12 controls the output temperature of the cooler 20 to maintain the indoor temperature at the first temperature value.

After the indoor volume is less than the decibel value and continues for a first set time, indicating that there is no human activity in the room, the electronic control module 12 controls the output temperature of the cooler 20 to maintain the indoor temperature at a second temperature value, wherein The second temperature value is greater than the first temperature value. Thereby, when there is no human activity in the room, the indoor temperature is maintained at a relatively high temperature to reduce the power consumed by the cooler 20. The purpose of continuing the first set time is to determine whether the person leaves the indoor space for a certain period of time, to avoid the situation that the person only temporarily leaves the indoor space and then returns, so that the cooler 20 operates too frequently.

When the indoor temperature is maintained at the second temperature value, if the indoor volume is still less than the decibel value, and after a second set time, the electronic control module 12 Controlling the output temperature of the cooler 20 to maintain the room temperature at a third temperature value, wherein the third temperature value is greater than the second temperature value. When the indoors continue to be free of personnel activities, the indoor temperature is continuously increased, and the energy consumption of the cooler 20 can be further reduced. In this embodiment, in the process of increasing the indoor temperature from the second temperature value to the third temperature value, the indoor temperature is gradually increased by using a temperature rising gradient manner, that is, the indoor temperature is increased by a predetermined temperature difference and passes through a third After setting the time, controlling to increase the output temperature of the temperature regulator to increase the indoor temperature by the predetermined temperature difference until the indoor temperature reaches the third temperature value; if the detected indoor volume is greater than the decibel value, the person has returned When indoors, the output temperature of the cooler 20 is controlled to return the indoor temperature to the first temperature value.

For example, the one shown in FIG. 5 is a temperature control mode in which the first temperature value T1 set by the user does not change with time. The second temperature value T2 is different from the first temperature value T1 by 1 ° C, and the third temperature value T3 is different from the first temperature value T1 by 5 ° C. The first set time t1 and the second set time t2 And the third set time t3 is set to 10 minutes. In the first 20 minutes, the indoor volume is greater than the decibel value, and the indoor temperature is maintained at the first temperature value T1 (23 ° C). At the 20th minute, the indoor volume is less than the decibel value. After the first set time t1 (10 minutes), the indoor temperature is increased to the second temperature value T2 (24 ° C); at this time, the indoor volume is still less than the decibel value. After the second set time t2 (10 minutes), the indoor temperature is increased by the predetermined temperature difference (1 ° C), and each time the third set time t3 (10 minutes) is increased by 1 ° C until the indoor temperature reaches the The third temperature value T3 (28 ° C). At the 100th minute, the indoor volume is again greater than the decibel value, and the indoor temperature returns to the first temperature value T1. The indoor temperature is adjusted in the same manner in the subsequent time, but when the indoor volume is greater than the decibel value, the indoor temperature is returned to the first temperature value T1.

In addition, the one shown in FIG. 6 is a temperature control mode in which the user sets different first temperature values T1 at different time periods. Wherein, at the 20th minute, the first temperature value T1 is 21 ° C, the indoor volume is less than the decibel value, and after the first set time t1 (10 minutes), the indoor temperature is increased to the second temperature value T2 (22 °C); at this time, the indoor volume is still less than the decibel value, after the second set time t2 (10) After the minute, the indoor temperature is increased, and each time the predetermined temperature difference (1 ° C) is increased and the third set time t3 (10 minutes) is passed, and then the temperature is increased by 1 ° C until the indoor temperature reaches the third temperature value T3 (26 ° C). ). At the 100th minute, the indoor volume is again greater than the decibel value, and the indoor temperature returns to the first temperature value T1. In order to prevent the indoor temperature from rising too high, the person feels that the indoor temperature is too hot after returning to the room. In practice, an upper limit temperature value TU can be set. For example, at the 190th minute, the indoor temperature reaches the upper limit temperature value TU (28). °C), the indoor temperature is no longer increased, and the indoor temperature is maintained at the second temperature value T2 (28 ° C) until the indoor volume is greater than the decibel value, and the indoor temperature is returned to the first temperature value T1.

In the above, the cooler 20 is controlled to increase the indoor temperature by using the indoor period without personnel movement, and the power consumed by the cooler 20 is reduced; and when the person returns to the room, the indoor temperature is restored to the originally set first temperature value T1. Does not affect the user's original usage habits.

The following is an explanation of the heating mode in the air conditioning system. In the heating mode, the temperature setting unit 10 performs a method of adjusting the indoor temperature as shown in FIG. 7, which is substantially the same as the step of the cold air mode, and the difference is: in the heating mode, the electronic control module 12 controls The temperature regulator is the heater 30, and the first temperature value T1 is greater than the second temperature value T2, and the second temperature value T2 is greater than the third temperature value T3. The detailed steps are not described herein again. The relationship between the indoor temperature and the indoor volume and time in the heating mode will be described.

The one shown in FIG. 8 is a temperature control method indicating that the first temperature value T1 set by the user does not change with time. Among them, in the first 20 minutes, the indoor volume is greater than the decibel value, and the indoor temperature is maintained at the first temperature value T1 (23 ° C). At the 20th minute, the indoor volume is less than the decibel value. After the first set time t1 (10 minutes), the indoor temperature is lowered to the second temperature value T2 (24 ° C); at this time, the indoor volume is still less than the decibel value. After the second set time t2 (10 minutes), the indoor temperature is gradually decreased by the temperature gradient, that is, the indoor temperature is first decreased by the predetermined temperature difference (1 ° C), and each time the third set time t3 (10 minutes) elapses. After that, reduce it by 1 °C until the indoor temperature reaches the third temperature. Degree T3 (18 ° C). At the 100th minute, the indoor volume is again greater than the decibel value, and the indoor temperature is returned to the first temperature value T1 (23 ° C). The indoor temperature is adjusted in the same manner in the subsequent time, but when the indoor volume is greater than the decibel value, the indoor temperature is returned to the first temperature value T1.

FIG. 9 shows a temperature control mode in which the user sets different first temperature values T1 at different time periods. Wherein, in the 20th minute, the first temperature value T1 is 25 ° C, the indoor volume is less than the decibel value, after the first set time t1 (10 minutes), the indoor temperature is lowered to the second temperature value T2 (24) °C); at this time, the indoor volume is still less than the decibel value, after the second set time t2 (10 minutes), the indoor temperature is lowered, and the predetermined temperature difference (1 ° C) is decreased and the third set time t3 is passed ( After 10 minutes), the temperature was further reduced by 1 ° C until the room temperature reached the third temperature value T3 (20 ° C). At the 100th minute, the indoor volume is again greater than the decibel value, and the indoor temperature is returned to the first temperature value T1 (25 ° C). In addition, in order to avoid the indoor temperature in the cold winter is too low, the person feels that the indoor temperature is too cold after returning to the room. In practice, a lower limit temperature value TD can be set. For example, at the 190th minute, the indoor temperature reaches the temperature. When the lower limit temperature value is TD (18 ° C), the indoor temperature is no longer lowered, and the indoor temperature is maintained at the second temperature value T2 (18 ° C) until the indoor volume is again greater than the decibel value, so that the indoor temperature is restored to the first A temperature value T1.

In the heating mode, when the indoor volume is less than the decibel value, the heater 30 is controlled to maintain the indoor temperature at a lower temperature, and the power consumed by the heater 30 can be reduced as well.

The method for adjusting the indoor temperature of the invention utilizes the volume of the detecting room as a basis for judging whether there is any activity of the person, and automatically adjusts the indoor temperature to a more energy-saving temperature when there is no personnel activity indoors (the indoor volume is less than the decibel value), reducing the duration Maintaining the energy consumed by the temperature regulator when the indoor temperature is at the first temperature value achieves the purpose of energy saving and carbon reduction; and when the person returns to the room (the indoor volume is greater than the predetermined volume value), the indoor temperature is automatically restored to the input by the user. The first temperature value, thereby effectively reducing the waste of energy unhelpful without affecting the comfort of the user.

The above description is only a preferred embodiment of the present invention, and the focus of the present invention is a method for adjusting the indoor temperature, and the applied air conditioning system is only for explaining the present invention, and the application of the present specification and the scope of the patent application are the same. Variations in the method of effect should be included in the scope of the patent of the present invention.
