Operation control means for controlling operation is provided,
The operation control means relates to an air conditioner configured to be switchable between a humidity control operation for controlling the humidity control means and a ventilation operation for stopping the humidity control action of the humidity control means.

  Such an air conditioner is designed to dehumidify the house while ventilating the inside of the house by performing a humidity control operation in which the humidity control means is operated to dehumidify the outside air by the humidity control means and supply it to the house.

JP 2003-4255 A

However, conventionally, since switching between humidity control operation and ventilation operation is performed by human operation, humidity control operation and ventilation operation are performed according to the moisture content state indicating some of the moisture content in the air in the house. However, there was a problem that it was not possible to switch appropriately.
In addition, since some of the moisture content in the air is difficult for humans to understand compared to the high and low temperatures, human operation involves humidity control according to the moisture content of the air in the house. It is difficult to properly switch to ventilation operation.
For example, humidity control operation by dehumidification when the humidity of the outside air is low and dehumidification is unnecessary, or humidity control operation by humidification is performed when the humidity of the outside air is high and humidification is unnecessary, etc. It is difficult to switch properly.
In addition, forgetting to switch between humidity control operation and ventilation operation, humidity control operation is performed when humidity control is unnecessary, and humidity control operation is not performed when humidity control is necessary To do.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide an air conditioner that can be operated by appropriately switching between a humidity control operation and a ventilation operation according to the moisture content state of the air in the house. There is.

A first characteristic configuration of the air conditioner according to the present invention includes an air supply air blowing means that ventilates an air supply air passage that supplies outside air as supply air into the house,
Exhaust air blowing means that ventilates the exhaust air passage that discharges the inside air that is the air inside the house as discharge air to the outside of the house, and
Humidity adjusting means that adjusts the humidity in a form that releases moisture absorbed from outside air flowing through the air supply air passage to the inside air flowing through the exhaust air passage;
Operation control means for controlling operation is provided,
The operation control means is configured to be switchable between a humidity adjustment operation for adjusting the humidity adjustment means and a ventilation operation for stopping the humidity adjustment action of the humidity adjustment means,
Absolute humidity detection means for detecting the absolute humidity of the inside air before being dehumidified by the humidity control means is provided,
Based on the detection information of the absolute humidity detection means, the operation control means executes the humidity adjustment operation when the absolute humidity of the inside air becomes a condition for humidity adjustment operation, and when the absolute humidity of the inside air becomes a condition for ventilation operation, It is characterized by being configured to perform ventilation operation.

That is, the absolute humidity of the inside air before being dehumidified by the humidity control means is detected by the absolute humidity detection means.
Then, based on the detection information of the absolute humidity detection means, the operation control means executes the humidity adjustment operation when the absolute humidity of the inside air becomes the condition for the humidity adjustment operation, and the ventilation operation when the absolute humidity of the inside air becomes the condition for the ventilation operation. Execute.

In other words, the absolute humidity of the inside air before it is released by the humidity control means corresponds to the absolute humidity in the air-conditioning space in the house, and the absolute humidity indicates the amount of moisture in the air. However, the detected value is not influenced by the temperature of the air, such as relative humidity.
The condition for humidity control operation is set to a condition indicating the state of absolute humidity that needs to be controlled by dehumidification. On the other hand, the condition for ventilation operation is to perform ventilation operation without performing humidity control operation. Set to a condition that indicates the state of absolute humidity.
Then, based on the detection information of the absolute humidity detection means, the humidity control operation is executed when the absolute humidity of the inside air becomes the condition for the humidity control operation, and the ventilation operation is executed when the absolute humidity of the inside air becomes the condition for the ventilation operation. By doing so, it becomes possible to appropriately switch between the humidity control operation and the ventilation operation according to the moisture content state of the air in the house.

By the way, relative humidity detection means that detects the relative humidity of the inside air before being released by the humidity control means is provided, and based on detection information of the relative humidity detection means, humidity control operation by dehumidification and ventilation operation are performed. It is assumed that it is configured to switch.
However, even if the moisture content is the same, the relative humidity changes according to the temperature of the air, so it is difficult to properly switch between humidity control and ventilation according to the moisture content of the air in the house. It is.
For example, when the temperature is 30 ° C. and the relative humidity is 50%, the relative humidity is about 90% when the temperature is 20 ° C. Therefore, for example, when the relative humidity is 70% or more, the humidity is adjusted. When the operation is performed and the relative humidity is lower than 70%, the ventilation operation is performed. Even when the absolute humidity is the same, when the temperature of the inside air varies depending on the presence or absence of cooling, the humidity adjustment operation is performed or the ventilation is performed. It is difficult to properly switch between humidity control and ventilation according to the moisture content of the air in the house.
Therefore, it has become possible to provide an air conditioner that can be operated by appropriately switching between a humidity control operation and a ventilation operation in accordance with the moisture content of the air in the house.

The second characteristic configuration is a supply air blowing means for ventilating the supply air passage for supplying outside air as supply air into the house,
Exhaust air blowing means that ventilates the exhaust air passage that discharges the inside air that is the air inside the house as discharge air to the outside of the house, and
Humidity adjusting means that adjusts moisture in a form that releases moisture absorbed from the inside air flowing through the exhaust air passage to the outside air flowing through the air supply air passage;
Operation control means for controlling operation is provided,
The operation control means is configured to be switchable between a humidity adjustment operation for adjusting the humidity adjustment means and a ventilation operation for stopping the humidity adjustment action of the humidity adjustment means,
Absolute humidity detection means for detecting the absolute humidity of the inside air before being absorbed by the humidity control means is provided,
Based on the detection information of the absolute humidity detection means, the operation control means executes the humidity adjustment operation when the absolute humidity of the inside air becomes a condition for humidity adjustment operation, and when the absolute humidity of the inside air becomes a condition for ventilation operation, It is characterized by being configured to perform ventilation operation.

That is, the absolute humidity of the inside air before being absorbed by the humidity adjusting means is detected by the absolute humidity detecting means.
Then, based on the detection information of the absolute humidity detection means, the operation control means executes the humidity adjustment operation when the absolute humidity of the inside air becomes the condition for the humidity adjustment operation, and the ventilation operation when the absolute humidity of the inside air becomes the condition for the ventilation operation. Execute.

In other words, the absolute humidity of the inside air before being absorbed by the humidity control means corresponds to the absolute humidity in the air-conditioned space in the house, and the absolute humidity indicates the amount of moisture in the air. Thus, the detected value is not affected by the temperature of the air, such as relative humidity.
The condition for humidity control operation is set to a condition indicating the state of absolute humidity that needs to be controlled by humidification. On the other hand, the condition for ventilation operation is to perform ventilation operation without performing humidity control operation. Set to a condition that indicates the state of absolute humidity.
Then, based on the detection information of the absolute humidity detection means, the humidity control operation is executed when the absolute humidity of the inside air becomes the condition for the humidity control operation, and the ventilation operation is executed when the absolute humidity of the inside air becomes the condition for the ventilation operation. By doing so, it becomes possible to appropriately switch between the humidity control operation and the ventilation operation according to the moisture content state of the air in the house.

By the way, a relative humidity detection means for detecting the relative humidity of the inside air before being absorbed by the humidity adjustment means is provided, and the operation is switched between the humidity adjustment operation by the humidification and the ventilation operation based on the detection information of the relative humidity detection means. Although the relative humidity varies depending on the temperature of the air even if the moisture content is the same, as described below, the relative humidity depends on the moisture content of the air in the house. It is difficult to switch between humidity control and ventilation.
For example, when the temperature is 20 ° C. and the relative humidity is 50%, the relative humidity is about 85% when the temperature is 12 ° C. Therefore, for example, when the relative humidity is 60% or less, the humidity is adjusted. When the operation is performed and the relative humidity is higher than 60%, the ventilation operation is performed. Even when the absolute humidity is the same, if the temperature of the inside air varies depending on the presence or absence of heating, the humidity adjustment operation is performed or the ventilation is performed. It is difficult to properly switch between humidity control and ventilation according to the moisture content of the air in the house.
Therefore, it has become possible to provide an air conditioner that can be operated by appropriately switching between a humidity control operation and a ventilation operation in accordance with the moisture content of the air in the house.

In addition to the second feature configuration described above, the third feature configuration is
The humidity control unit is disposed so that a part thereof is positioned in the supply air path and the other part is positioned in the exhaust air path, and is driven and rotated by a drive unit, and the supply air It is configured to include a heating means that heats the outside air at a location closer to the ventilation direction than the humidity control body in the road,
In the humidity control operation, the operation control unit is configured to operate the drive unit and to heat the humidity control unit with the heating unit in a heating operation state, and as the ventilation operation, A normal ventilation operation in which the driving means is stopped and the heating means is stopped to stop the humidity control action of the humidity control means; and the humidity control is performed by stopping the driving means and bringing the heating means into a heating action state. It is characterized in that it can be switched to hot air ventilation operation to stop the humidity control action of the means.

That is, in the humidity control operation, the operation control unit operates the drive unit, puts the heating unit into a heating action state, and controls the humidity control unit.
And in this humidity control operation, when the outside air heated by the heating means passes through the humidity control body that is driven to rotate, the moisture of the inside air absorbed by the humidity control body is released and humidified. The humidified and heated outside air is supplied into the house as supply air.
In addition, the operation control means, as a ventilation operation, stops the driving means and stops the heating means to stop the humidity control action of the humidity control means by stopping the heating means, and stops the driving means and heats the heating means. It is possible to switch to a hot air ventilation operation in which the humidity control action of the humidity control means is stopped in the operating state.
In these normal ventilation operation and hot air ventilation operation, the rotation of the humidity control body is stopped, so that the humidity control action of the humidity control means is stopped.
Then, when switched to normal ventilation operation, the outside air is ventilated in the form of being supplied to the house as supply air as it is, and when switched to hot air ventilation operation, the outside air is heated by the heating means. The interior of the house is ventilated in a form that is later supplied into the house as supply air.

In other words, in the humidity control operation, humidified and heated outside air is supplied into the house as supply air, so that the resident feels cold even when the temperature of the outside air is low, such as in winter, The house can be humidified.
In addition, since the ventilation operation can be switched between a normal ventilation operation and a hot air ventilation operation, when the outside air is supplied to the house as supply air as it is, there is no risk that the resident feels cold. If the residents are likely to feel cold when the house is ventilated and the outside air is supplied to the house as supply air, it will be possible to perform the warm air ventilation operation, and the residents will be prevented from feeling cold. In the state, it can ventilate the house.
Therefore, it has become possible to humidify and ventilate the house in a state where the residents feel cold.

In addition to any of the first to third feature configurations described above, the fourth feature configuration is
The supply air passage is branched into a plurality of air to supply supply air to a plurality of air-conditioning target spaces in the house,
The inside air suction portion in the exhaust air passage is configured to suck and act on a specific space in a house that is communicated with the plurality of air-conditioning target spaces.

  That is, the supply air is supplied to the plurality of air-conditioning target spaces in the house through the air supply air passage, and the internal air in the plurality of air-conditioning target spaces in the house merges with the specific space in the house and is sucked from the suction unit. Into the exhaust air duct.

That is, since supply air is supplied to a plurality of air-conditioning target spaces in a house, the plurality of air-conditioning target spaces can be conditioned.
When the humidity of a plurality of air conditioning target spaces is adjusted as described above, the temperature and humidity of the inside air in the plurality of air conditioning target spaces vary depending on the presence or absence of cooling, the presence or absence of heating, and the like.
In such a case, by detecting the absolute humidity of the inside air from a plurality of air-conditioning target spaces sucked in a combined state from one suction part, regardless of whether each air-conditioning target room is cooled or not heated The absolute humidity can be detected as an indication of the moisture content of the air as a whole of the plurality of air conditioning target spaces in the house.
And since it switches to humidity control operation and ventilation operation based on the absolute humidity detected in that way, it becomes possible to perform appropriately the humidity control of the several air-conditioning object space in a house.

In addition to any of the first to fourth feature configurations described above, the fifth feature configuration is
A setting means for changing and setting the conditions for humidity control operation and the conditions for ventilation operation is provided.

That is, the humidity control operation condition and the ventilation operation condition can be changed and set by the setting means.
That is, the humidity control condition and the ventilation operation condition can be changed and set according to the preference of the resident of the house, so that the humidity can be adjusted to a more comfortable state.
In addition, when the fifth feature configuration is implemented in addition to the fourth feature configuration described above, depending on the absolute humidity relationship between the specific space in the house where the suction portion performs suction and a plurality of air-conditioning target spaces. The conditions for humidity control and the conditions for ventilation operation can be changed and set.
For example, when a specific space is adjacent to a humid place such as a washroom, the absolute humidity detection value by the absolute humidity detection means is higher than the average absolute humidity of the plurality of air-conditioning target spaces.
In such a case, it is possible to adjust the humidity of the plurality of air-conditioning target spaces to a more comfortable state by changing and setting the conditions for the humidity control operation and the conditions for the ventilation operation to the conditions on the higher absolute humidity side.
Therefore, the humidity of the air-conditioning target space can be adjusted to a more comfortable state.

In addition to any of the first to fifth feature configurations described above, the sixth feature configuration is
The present invention is characterized in that there is provided display means for displaying whether the absolute humidity of the inside air detected by the absolute humidity detection means is one of a plurality of levels of humidity level.

In other words, the display means displays whether the absolute humidity of the inside air detected by the absolute humidity detection means is one of a plurality of levels of humidity level.
In other words, because the humidity level in the house is displayed as an absolute humidity level that is not affected by temperature if the amount of moisture contained in the air is the same, It is possible to display the moisture content of the air in the house appropriately and in a state that is easy for the resident of the house to understand.
By the way, it is assumed that the absolute humidity of the inside air detected by the absolute humidity detection means is displayed on the display means, but the absolute humidity itself is difficult to understand whether the humidity in the air is high or low. It is.
In addition, it is assumed that the relative humidity of the inside air is displayed on the display means, but even if the amount of moisture contained in the air is the same, the relative humidity depends on the temperature of the air. Cannot be displayed properly.
Therefore, the moisture content of the air in the house can be displayed appropriately and in a state that is easy for the resident of the house to understand.

In addition to any of the first to sixth feature configurations described above, the seventh feature configuration is
The absolute humidity detecting means detects the temperature of the inside air, the relative humidity detecting means for detecting the relative humidity of the inside air, and the absolute humidity based on the detection information of each of the temperature detecting means and the relative humidity detecting means. The absolute humidity deriving means to be obtained,
The absolute humidity deriving means is characterized in that it is configured to obtain absolute humidity based on absolute humidity deriving information indicating the relationship between temperature and relative humidity and absolute humidity.

  That is, the temperature of the inside air is detected by the temperature detecting means, the relative humidity of the inside air is detected by the relative humidity detecting means, the detection information of each of the temperature detecting means and the relative humidity detecting means by the absolute humidity deriving means, and the temperature and The absolute humidity is obtained based on the information for deriving the absolute humidity indicating the relationship between the relative humidity and the absolute humidity.

That is, since there is a certain relationship between the air temperature and relative humidity and the absolute humidity, the absolute humidity of the inside air can be obtained by detecting the temperature of the inside air and the relative humidity.
Since the temperature detection means and the relative humidity detection means are inexpensive, the absolute humidity detection means can be directly connected to the absolute humidity by configuring the absolute humidity detection means using the temperature detection means and the relative humidity detection means. Compared to the case of a so-called absolute humidity sensor configured to detect, a reduction in cost can be achieved.
Accordingly, it has become possible to appropriately switch between the humidity control operation and the ventilation operation according to the moisture content state of the air in the house while reducing the cost.
