Hereinafter, with reference to the accompanying drawings an embodiment of an air conditioner according to the present invention will be described in more detail.

1 is a configuration diagram schematically showing an embodiment of an air conditioner according to the present invention.

Referring to FIG. 1, the air conditioner according to the present embodiment performs air conditioning, that is, cooling and / or heating of an indoor space. In addition, the air conditioner additionally performs dehumidification of the indoor space. To this end, the air conditioner includes an air conditioner 10, an input unit 20, an indoor temperature sensor 30, and an outdoor temperature sensor 40.

In more detail, the air conditioning unit 10 is for air conditioning and dehumidification of the indoor space. The air conditioning unit 10 may include components constituting the heat exchange cycle, for example, a compressor, an outdoor heat exchanger, an expansion valve, and an indoor heat exchanger. And the air conditioning and dehumidification of the indoor space is made by heat exchange between the refrigerant circulating the air conditioning unit 10 and the indoor air and outdoor air. Since the configuration of the air conditioning unit 10 is well known, a detailed description thereof will be omitted.

The input unit 20 receives a signal for air conditioning and dehumidification of the indoor space. In particular, the input unit 20 receives a signal for selecting a dehumidification mode for dehumidifying an indoor space and setting an input dehumidification temperature T0. Here, the input dehumidification temperature T0 means a dehumidification temperature of the indoor space expected by the user.

And the indoor temperature detection unit 30 detects the temperature of the indoor space. In addition, the outdoor temperature detecting unit 40 detects the temperature of the outdoor space.

The controller 50 controls the air conditioning unit 10 to perform air conditioning or dehumidification of the indoor space according to the signal input by the input unit 20. In particular, when the input unit 20 receives a signal for selecting the dehumidification mode and inputting the input dehumidification temperature T0, the controller 50 is set according to the input dehumidification temperature T0. The air conditioning unit 10 is controlled to dehumidify the indoor space for a predetermined dehumidification operation time t at a predetermined dehumidification temperature T.

At this time, the set dehumidification temperature (T) is increased step by step. For example, when the input dehumidification temperature T0 is 22 degrees C or less, the set dehumidification temperature T is set to the temperature value which increases by 1 degreeC interval in the range of 22 degreeC or more and 28 degrees C or less. Further, when the input dehumidification temperature T0 is greater than 22 ° C and less than 27 ° C, the set dehumidification temperature T is increased at intervals of 1 ° C in a range of 28 ° C or less and a temperature value of raising the input dehumidification temperature T0. It is set to the temperature value. And the said set dehumidification temperature T is set to 28 degreeC, when the said input dehumidification temperature T0 is more than 27 degreeC. An example of the setting of the set dehumidification temperature T according to the input dehumidification temperature T0 by the controller 50 is as shown in Table 1 below.

Input dehumidification temperature 22 ℃ or less More than 22 degrees Celsius and less than 23 degrees Celsius More than 23 degrees Celsius and less than 24 degrees Celsius More than 24 degrees Celsius and 25 degrees Celsius or less More than 25 degrees Celsius and less than 26 degrees Celsius More than 26 degrees Celsius and less than 27 degrees Celsius Above 27 ℃ Set dehumidification temperature





22 ℃
23 ℃ 23 ℃ 24 ℃ 24 ℃ 24 ℃ 25 ℃ 25 ℃ 25 ℃ 25 ℃ 26 ℃ 26 ℃ 26 ℃ 26 ℃ 26 ℃ 27 ℃ 27 ℃ 27 ℃ 27 ℃ 27 ℃ 27 ℃ 28 ℃ 28 ℃ 28 ℃ 28 ℃ 28 ℃ 28 ℃ 28 ℃

Therefore, for example, when the input dehumidification temperature T0 is 22 degrees Celsius, the set dehumidification temperature T is set to a temperature value that is increased at intervals of 1 degree Celsius in a range of 22 degrees Celsius to 28 degrees Celsius. do. Therefore, when the input dehumidification temperature T0 is 22 degrees Celsius, the set dehumidification temperature T is 22 degrees Celsius, 23 degrees Celsius, 24 degrees Celsius, 25 degrees Celsius, 26 degrees Celsius, 27 degrees Celsius, and 28 degrees. It is set to a temperature value that is incrementally increased in degrees Celsius. When the input dehumidification temperature T0 is 25 degrees Celsius, the set dehumidification temperature T is increased in steps of 25 degrees, 26 degrees, 27 degrees and 28 degrees Celsius in steps of 1 degree. It is set to a value. Hereinafter, for convenience of explanation, the set dehumidification temperature T, which is set to 22 degrees Celsius to 28 degrees Celsius, is respectively set to first to sixth degrees.

On the other hand, the set dehumidification temperature (T) is compensated according to the temperature difference between the indoor temperature sensed by the indoor temperature detector 30 and the outdoor temperature sensed by the outdoor temperature detector 40. In the present embodiment, the set dehumidification temperature when the temperature difference between the indoor temperature and the outdoor temperature is 5 degrees Celsius or more at the time when the set dehumidification temperature T is increased from 26 degrees to 27 degrees Celsius at 1 degree intervals. (T) is set to 28 degrees C increased by 2 degrees Celsius, not 27 degrees C increased by 26 degrees to 1 degree. In other words, when the set dehumidification temperature (T) is 26 degrees Celsius, the dehumidification operation of the indoor space is started at the set dehumidification temperature (T) and is set according to the set dehumidification temperature (T). When the temperature difference between the indoor temperature and the outdoor temperature when the time t (the fifth dehumidification operation time t to be described later) elapses is 5 degrees or more, the set dehumidification temperature T is 27 degrees Celsius. Is set to 28 degrees Celsius. This reduces the power required for dehumidification of the indoor space by increasing the set dehumidification temperature (T) in the case of a temperature range in which the influence on the dehumidification of the indoor space is substantially small, and at the same time reduces the temperature difference between the indoor temperature and the outdoor temperature. This is to increase the adaptability when the user goes out from indoors to outdoors.

Meanwhile, the dehumidification operation time t is a temperature value of the set dehumidification temperature T, that is, the first to seventh dehumidification temperatures T1, T2, T3, T4, T5, T6, and T7. Depending on the time. At this time, the dehumidification operation time (t) may be set to a time increased according to the temperature value of the set dehumidification temperature (T). For example, when the set dehumidification temperature T is set as shown in Table 1, the dehumidification operation time t may be set as shown in Table 2 below.

Set dehumidification temperature 22 degrees 23 degrees 24 degrees 25 degrees 26 degrees 27 degrees 28 degrees Dehumidification run time 19 minutes 23 minutes 30 minutes 35 minutes 40 minutes 54 minutes 70 minutes

In other words, the dehumidification operation time t is set to 21 minutes or less, preferably 19 minutes, at the first dehumidification temperature T1. The dehumidification operation time t is set to a time of more than 21 minutes and no more than 26 minutes at the second dehumidification temperature T2, preferably 23 minutes. The dehumidification operation time t is set to a time of more than 26 minutes and 33 minutes or less at the third dehumidification temperature T3, preferably 30 minutes, and more than 33 minutes at the fourth dehumidification temperature T4. The time is set to minutes or less, preferably 35 minutes. The dehumidification operation time t is set to a time of more than 38 minutes and 47 minutes or less, preferably 40 minutes at the fifth dehumidification temperature T5, and more than 47 minutes at the sixth dehumidification temperature T6. The time is set to minutes or less, preferably 54 minutes, and at the seventh dehumidification temperature T7, the time is set to more than 62 minutes, preferably 70 minutes. Hereinafter, for convenience of explanation, the dehumidification operation time when the dehumidification operation time t at the first dehumidification temperature T1 is the first dehumidification time t1 and the set dehumidification temperature T is 23 ° C. t) the second dehumidification time t2, the dehumidification operation time t when the set dehumidification temperature T is 24 ° C, the third dehumidification time t3, and the set dehumidification temperature T is 25 ° C. Is the fourth dehumidification time t4 when the dehumidification operation time t is set, and the dehumidification operation time t when the set dehumidification temperature T is 26 ° C. is the fifth dehumidification time t5 and the setting. The dehumidification operation time t when the dehumidification temperature T is 27 ° C is the sixth dehumidification time t6, and the dehumidification operation time t when the set dehumidification temperature T is 28 ° C. The dehumidification time t7 is called.

Hereinafter, with reference to the accompanying drawings an embodiment of the air conditioner control method according to the present invention will be described in more detail.

Figure 2 is a control flow chart showing an embodiment of the air conditioner control method according to the present invention, Figure 3 is a graph comparing the dehumidification efficiency of the embodiment of the present invention and the interior space of the prior art.

Referring to FIG. 2, first, the input unit 20 receives an input dehumidification temperature T0. (S11) At this time, the input unit 20 sets the input dehumidification temperature T0 in units of 1 degree Celsius, 0.5 degrees Celsius. It can be input in units of 0.1 degrees Celsius.

The controller 50 determines whether the input dehumidification temperature T0 input by the input unit 20 is 22 degrees Celsius or less. (S13) In the thirteenth step, the input dehumidification temperature T0. Is determined to be 22 degrees Celsius or less, the set dehumidification temperature (T) is set to 22 degrees Celsius, that is, the first dehumidification temperature (T1). (S15) And the control unit 50 is the first dehumidification temperature (T1) The air conditioning unit 10 is controlled so that the indoor space is dehumidified.

Next, the controller 50 determines whether the first dehumidification time t1 has elapsed after the dehumidification of the indoor space is started at the first dehumidification temperature T1. (S17) And in the 17th step, When it is determined that the first dehumidification time t1 has elapsed, the set dehumidification temperature T is 23 degrees C, which is a temperature increased by 1 degree from the first dehumidification temperature T1, that is, the second dehumidification temperature T2. The controller 50 controls the air conditioning unit 10 to dehumidify the indoor space at the second dehumidification temperature T2.

On the other hand, the set dehumidification temperature (T), similar to the 19th step, the interval by 1 degree until reaching the second dehumidification temperature (T2), that is to say the fifth dehumidification temperature (T5), that is, 26 degrees Celsius (S23) (S27) (S31) In other words, the set dehumidification temperature T is sequentially set to the third to fifth dehumidification temperatures T3 (T4) and T5.

In addition, the controller 50 controls the air conditioning unit 10 to dehumidify the indoor space at the third to fifth dehumidification temperatures T3, T4, and T5. In addition, the control unit 50, similar to the twenty-first step, after the dehumidification of the indoor space is started at the third to fifth humidity temperature (T3) (T4) (T5), respectively, the third to fifth dehumidification time ( It is determined whether t3, t4, t5 has elapsed. (S25) (S29) (S33) And if it is determined that the third and fifth dehumidification times t3 (t4) have elapsed, the twenty-seventh Steps 31 and 35 are performed.

However, if it is determined in step 33 that the fifth dehumidification time t5 has elapsed, the controller 50 may include an indoor temperature sensed by the indoor temperature detector 30 and the outdoor temperature detector 40, respectively. It is determined whether the temperature difference tΔ of the outdoor temperature is 5 degrees or more (S35). In step 35, if the temperature difference tΔ is less than 5 degrees, the set dehumidification temperature T is determined. Is set to 26 degrees Celsius which is increased by 1 degree from the fifth dehumidification temperature T5, that is, the sixth dehumidification temperature T6. (S37) Next, the controller 50 controls the sixth dehumidification temperature ( The air conditioner 10 is controlled to dehumidify the indoor space with T6), and it is determined whether the sixth dehumidification time t6 has elapsed after the dehumidification of the indoor space is started with the sixth dehumidification temperature T6. S39)

In operation 39, when it is determined that the sixth dehumidification time t6 has elapsed, the set dehumidification temperature T is set to the seventh dehumidification temperature T7. (S41) Accordingly, the controller 50 The indoor space is controlled to be dehumidified at the seventh dehumidification temperature T7. In addition, the control unit 50 determines whether the seventh dehumidification time t7 has elapsed after the dehumidification of the indoor space is started at the seventh dehumidification temperature T7. When it is determined that the 7 dehumidification time t7 has elapsed, the dehumidification of the indoor space ends.

On the other hand, in step 35, when the temperature difference tΔ is determined to be 5 degrees C or more, steps 41 and 43 are performed. In other words, the set dehumidification temperature (T) is set to 27 degrees, which is increased by 2 degrees from the fifth dehumidification temperature (T5), that is, the seventh dehumidification temperature (T7), the seventh dehumidification temperature (T7) The indoor space is dehumidified during the seventh dehumidification time t7. In other words, when the temperature difference tΔ is 5 degrees Celsius or more, the set dehumidification temperature T is set to the sixth dehumidification temperature T6, and the 37th step and the sixth dehumidification temperature T6 are used. Step 39 in which the indoor space is dehumidified during the sixth dehumidification time t6 is omitted.

On the other hand, if it is determined in step 13 that the input dehumidification temperature (T0) is not less than 22 degrees Celsius, the controller 50 is the input dehumidification temperature (T0) is 23 degrees or less, that is, 22 degrees Celsius or more 23 degrees In step 45, if the input dehumidification temperature T0 is greater than 22 degrees C and less than 23 degrees C, steps 19 through 43 are performed. Similarly, if it is determined in step 45 that the input dehumidification temperature T0 is not less than 22 degrees Celsius, the controller 50 determines that the input dehumidification temperature T0 is greater than 23 degrees and less than 24 degrees Celsius. It is determined whether it is more than 24 degrees C and less than 25 degrees C, more than 25 degrees C and less than 26 degrees C, and more than 26 degrees C and less than 27 degrees C. (S47) (S49) (S51) (S53) and the said control part 50 ) According to the temperature values of the input dehumidification temperature T0 determined in the 47th, 49th, 51th and 53rd stages, the 23rd to 43rd stages and the 27th to 27th stages. Step 43, steps 31 through 43, or steps 35 through 43 are performed.

Meanwhile, referring to FIG. 3, the dehumidification efficiency in the case of dehumidification of the indoor space according to the present embodiment and the case of dehumidification of the indoor space according to the prior art may be compared. In Figure 3, A represents the relative humidity of the indoor space over time when the indoor space is dehumidified according to the present embodiment. And B and C respectively represent the relative humidity of the indoor space over time when the indoor space is dehumidified by the prior art. In case of A, the relative humidity of the indoor space is significantly reduced compared to B and C. Thus, according to this embodiment, the relative humidity of the indoor space is significantly reduced compared to the prior art, it can be provided a more comfortable environment.

In addition, when dehumidifying the indoor space according to the prior art takes about 1900W of power. However, according to this embodiment, only 900W of power, which is about 60% of the power required in the prior art, is required. Therefore, according to this embodiment, it can be seen that the indoor space can be dehumidified more economically.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications, and variations will be apparent to those skilled in the art in light of the above teachings. will be.
