Description

Method for controlling indoor humidity during dehumidification operation of air conditioning system and air conditioning system using the same}

The present invention relates to a method for controlling indoor humidity during a dehumidifying operation of an air conditioning system and an air conditioning system using the same, and more particularly, to an air conditioning system in which a target value of indoor humidity is automatically set differently depending on temperature, thereby saving energy while securing comfort. It relates to a method for controlling indoor humidity during dehumidification operation of an air conditioning system that can save energy and an air conditioning system using the same.

In general, an air conditioning system is often referred to as a cooling device, but more precisely, it includes all devices that adjust the indoor space to have temperature, humidity, and airflow distribution suitable for occupants' activities or purify indoor air. .

Conventional air conditioning systems have a problem in that comfort of occupants may not be secured when the indoor humidity is high even if the indoor temperature is maintained within a set temperature range. In order to solve this problem, when the manager further lowers the set temperature, the indoor humidity is lowered, but the indoor temperature is lower than the comfortable temperature range, causing the occupant to feel cold. In addition, when the indoor humidity is set to the set humidity and controlled, even if the indoor humidity is lowered due to the decrease in the indoor temperature, it continues to operate to lower the set humidity, and energy is wasted.

A method of controlling indoor humidity in the air conditioning system configured as described above will be described below.

3 is a flowchart illustrating a control method for controlling indoor humidity during a dehumidifying operation of an air conditioning system according to an embodiment of the present invention.

Referring to FIG. 3 , a data construction step (S1) of constructing and storing the temperature and humidity data in the database 50, an indoor humidity setting step (S2) of setting an indoor humidity target value according to the input temperature, and and a dehumidification step (S3) of performing a dehumidification operation according to a target humidity value.

The data building step (S1) can also be performed by the control unit 100, and of course it is possible to be performed by a server (not shown) that communicates with the control unit 100 by wire or wirelessly.

In the data building step (S1), the indoor appropriate humidity for the temperature is selected in advance according to a plurality of preset dehumidification patterns, and temperature and humidity data for the relationship between the temperature and the indoor appropriate humidity are constructed and stored in the database 50. It is a step to

The temperature and humidity data is data including indoor appropriate humidity set differently according to temperature from data collected through experiments or simulations of operation of the air conditioning system, and data set differently according to a plurality of preset dehumidification patterns.

That is, since the indoor humidity at which the user feels comfortable varies depending on the temperature, the humidity at which the user feels comfortable is selected and set as the appropriate indoor humidity for the specific temperature to construct temperature and humidity data.

An appropriate indoor humidity for the above temperature is set in a range between a preset upper humidity limit value and a preset lower humidity limit value. In this embodiment, the upper humidity limit is 75%, and the lower humidity limit is 35%.

The optimum indoor humidity for the temperature may be set to an optimal humidity selected according to at least one of mold occurrence, disease occurrence, discomfort index, and energy consumption rate. Whether or not the mold occurs, whether the disease occurs, the discomfort index, and the energy consumption rate may be obtained from data collected through experiments or simulations. For example, since the mold occurs when the indoor humidity is about 75% or more, the optimum indoor humidity may be set to be less than 75%. The upper limit value of the humidity may be determined according to whether or not the mold is generated. The diseases include respiratory diseases, skin diseases, and the like. Since the disease occurs when the indoor humidity is about 30% or less, the optimum indoor humidity may be set to exceed 35%. That is, the lower limit of humidity may be determined according to whether the disease occurs. The discomfort index can be calculated using temperature and humidity, and a known calculation formula can be used. Accordingly, a humidity whose discomfort index calculated at a specific temperature is equal to or less than a preset value may be selected as an appropriate indoor humidity for a specific temperature. The energy consumption rate may also be calculated using a known calculation formula, and a humidity in which the energy consumption rate calculated at a specific temperature is equal to or less than a preset energy consumption rate set value may be selected as the appropriate indoor humidity for the specific temperature.

On the other hand, since there is a large deviation in the desired indoor humidity for each person, a plurality of dehumidification patterns are selected in consideration of the user's taste, and temperature and humidity data are constructed differently according to the plurality of dehumidification patterns, so that the user can select the desired dehumidification pattern. allow you to choose

In this embodiment, referring to FIGS. 4 and 5 , the plurality of dehumidification patterns include a pleasant dehumidification pattern, an eco dehumidification pattern, and a dry dehumidification pattern. However, it is not limited thereto, and the type or number of dehumidification patterns can be variously changed and applied.

The comfortable dehumidification pattern is composed of temperature and humidity data from which most users can feel a level of comfort. That is, the comfortable dehumidification pattern includes, for example, temperature and humidity data in which humidity is selected as an appropriate indoor humidity when the discomfort index is less than a preset discomfort index at a specific temperature.

The eco-dehumidification pattern includes temperature and humidity data capable of minimizing an energy consumption rate. That is, the eco-dehumidification pattern includes, for example, temperature and humidity data in which humidity is selected as an appropriate indoor humidity when an energy consumption rate at a specific temperature is less than a preset energy consumption rate. Accordingly, the appropriate indoor humidity of the eco dehumidification pattern may be set higher than the appropriate indoor humidity of the comfortable dehumidification pattern.

The drying and dehumidifying pattern is composed of temperature and humidity data that can be selected by users who are more sensitive to humidity to create a drier indoor environment. That is, the drying and dehumidifying pattern includes, for example, temperature and humidity data in which a humidity set lower than the indoor appropriate humidity of the comfortable dehumidifying pattern by a preset humidity difference is selected as an indoor appropriate humidity. Here, the humidity difference may be set differently according to temperature.

As described above, temperature and humidity data in which indoor appropriate humidity for temperature is set differently according to the plurality of dehumidification patterns may be stored in the database 50 .

In the indoor humidity setting step (S2), the control unit 100 automatically sets a target indoor humidity value according to the indoor temperature of the air-conditioning room.

That is, the temperature sensor 70 detects the indoor temperature of the air-conditioning room in real time and transmits the detected temperature to the control unit 100, and the controller 100 determines the current indoor temperature of the air-conditioning room input from the temperature sensor 70. Set the indoor humidity target value accordingly.

On the other hand, when the user selects one of the plurality of dehumidification patterns, the control unit 100 determines the appropriate indoor humidity for the indoor temperature of the air-conditioning room from the temperature and humidity data of the dehumidification pattern selected by the user in the database 50. extracted, and the extracted indoor humidity is set as the indoor humidity target value.

For example, referring to FIG. 5 , when the input dehumidification pattern is an eco dehumidification pattern and the input temperature is 26° C., the appropriate indoor humidity for a temperature of 26° C. is 73% in the temperature and humidity data of the eco dehumidification pattern. Therefore, the optimal indoor humidity of 73% is set as the indoor humidity target value.

On the other hand, if the input dehumidification pattern is a comfortable dehumidification pattern and the input temperature is 26°C, the optimum indoor humidity for a temperature of 26°C is 62% in the temperature and humidity data of the comfortable dehumidification pattern, so the appropriate indoor humidity is 62%. is set as the indoor humidity target value.

In addition, if the input dehumidification pattern is a dry dehumidification pattern and the input temperature is 26°C, the optimal indoor humidity for a temperature of 26°C is 49% in the temperature and humidity data of the dry and dehumidifying pattern, so the optimal indoor humidity is 49%. is set as the indoor humidity target value.

That is, at the same temperature of 26°C, the appropriate indoor humidity is 73% for the eco dehumidification pattern, 62% for the comfortable dehumidification pattern, and 49% for the dry dehumidification pattern. set differently.

Therefore, in the case of the eco dehumidification pattern, the optimal indoor humidity is set to the highest level to reduce energy consumption, and in the case of the dry dehumidification pattern, the optimal indoor humidity is set to the lowest level to satisfy the user's comfort level who prefers a relatively dry environment. can do it

Meanwhile, if the user does not select the dehumidification pattern, the control unit 100 may extract an appropriate indoor humidity from temperature and humidity data of the comfortable dehumidification pattern among the plurality of dehumidification patterns. That is, in the present embodiment, the pleasant dehumidification pattern among the plurality of dehumidification patterns is set as default, but is not limited thereto, and other patterns may be set as default according to the air conditioning environment or the user's inclination. do.

As described above, in the present embodiment, when the indoor temperature of the air-conditioning room is input to the control unit 100, the optimal indoor humidity suitable for the room temperature of the air-conditioning room is automatically set as the indoor humidity target value.

When the indoor humidity target value is automatically set in the indoor humidity setting step (S2), the control unit 100 performs a dehumidifying operation according to the indoor humidity target value.

Therefore, in the present invention, the indoor humidity target value is automatically set according to the indoor temperature of the air-conditioning room, so that the user does not have to separately input the indoor humidity target value.

In addition, since the optimal indoor humidity for the indoor temperature of the air-conditioning room is automatically set as the indoor humidity target value and dehumidification is performed, the air-conditioning room can be controlled to the optimal humidity that can save energy while improving the comfort of occupants. can

As described above, in the present embodiment, the indoor humidity target value is set differently according to the indoor temperature of the air-conditioning room and the dehumidifying operation is performed. As a result, the dehumidifying operation is performed unnecessarily at a high indoor temperature, thereby increasing the discomfort index and increasing energy consumption. problems can be avoided.

In addition, in this embodiment, the air conditioning system is composed of a hybrid dehumidifying air conditioner combining a heat pump and a desiccant dehumidifying rotor, so that when installed together with an existing air conditioner in an air conditioning room, the hybrid dehumidifying air conditioner takes charge of latent heat load, The air conditioner is responsible for the sensible heat load, enabling more effective cooling and dehumidification of the air conditioning room.

On the other hand, in the above embodiment, the air conditioning system has been described as being a cooling dehumidifier including a heat pump, but is not limited thereto, and a desiccant is provided by using a separate heater or heat exchanger without using a heat pump. Of course, it can also be applied to regenerating dry dehumidifiers.

In addition, the air conditioning system is not limited to the above embodiment, and the air conditioning system may be a thermo-hygrostat capable of controlling both temperature and humidity without using a desiccant, that is, an air conditioner capable of dehumidifying operation.

When the air conditioning system is an air conditioner, a user inputs a desired cooling target temperature to the input unit 60, and the controller 100 receives the cooling target temperature from the input unit 60.

The control unit 100 extracts an appropriate indoor humidity according to a dehumidification pattern input by a user and a cooling target temperature from the temperature and humidity data stored in the database 100, and automatically sets the extracted appropriate indoor humidity as an indoor humidity target value. can

Therefore, even if the indoor temperature of the air conditioning room changes due to the cooling operation of the air conditioner, the dehumidifying operation can be performed with the optimum indoor humidity suitable for the cooling target temperature.

However, the present invention is not limited thereto, and even when the air conditioning system is an air conditioner, it is also possible to automatically set the extracted indoor humidity as a target indoor humidity value by extracting an appropriate indoor humidity according to the indoor temperature of the air conditioning room.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is only exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical scope of protection of the present invention should be determined by the technical spirit of the appended claims.
