た空気調和装置の制御方法に関するものである。Detailed Description of the Invention "Field of Industrial Application" The present invention provides a method for dehumidifying the air in a case where the operation mode is switched to at least one of cooling and dehumidifying modes according to changes in indoor temperature, outdoor temperature, and indoor humidity. The present invention relates to a method of controlling an air conditioner in which a set temperature is varied according to indoor temperature.

の切換え条件には含まれていなかつた。"Prior Art" Conventional air conditioner control methods have at least "cooling" and "dehumidifying" operation modes. For example, when the "cooling" mode is set, changes in temperature are detected and the system detects strong winds, moderate winds, It is designed to automatically switch to low wind, etc., but if you set either "cooling" or "dehumidification" operation mode, it will automatically switch between the two operation modes unless you manually change the mode. I couldn't do it. Furthermore, humidity was not included in the operating mode switching conditions.

るという問題があつた。``Problem to be solved by the invention'' However, during the rainy season, there are times when it is desired to select the dehumidifying operation mode in the morning and evening and switch to the cooling operation mode during the day. This is not possible with the method, and as a result, leaving the operating mode as it is when there is a wide change in temperature causes extreme discomfort, and since humidity is not included in the switching conditions, the operation mode does not change even when the humidity is low. There were problems such as dehumidifying operation and wasting energy. Furthermore, since dehumidification operation is also a weak cooling operation, if the dehumidification setting temperature is high, the compressor will turn off and dehumidification will not be possible, and conversely, if the dehumidification setting temperature is low, the unnecessary cooling effect will be too strong. It was hot.

In an air conditioner that sometimes performs dehumidification operation, the dehumidification mode in the dehumidification mode in which the detected indoor humidity exceeds a set value is set to multiple stages by setting the minimum dehumidification set temperature to multiple stages. , when the off time of the compressor in the dehumidification mode continues for a set time, the dehumidification operation is performed in a dehumidification mode in which the minimum dehumidification set temperature is lowered by a predetermined step, and the compressor is on in the dehumidification mode, and When the temperature obtained by subtracting a certain temperature from the detected indoor temperature exceeds the minimum dehumidification setting temperature for a certain period of time, the dehumidification operation is performed in a dehumidification mode in which the minimum dehumidification setting temperature is increased by a predetermined step. This is a characteristic control method.

ドで除湿運転をする。"Operation" First, the indoor humidity is detected, and only when the indoor humidity is higher than the set indoor humidity (for example, 60%), the mode is shifted to the dehumidifying mode, and when the indoor humidity is lower than the set indoor humidity, the mode is shifted to the non-dehumidifying mode. In this dehumidification mode, next, it is checked whether the compressor is on. If the compressor is on, the dehumidification mode can be entered. If the indoor temperature drops and the compressor is turned off for a certain period of time, dehumidification is not possible at the selected minimum dehumidification setting temperature, so dehumidification is performed in a dehumidification mode that lowers the minimum dehumidification setting temperature by a predetermined level. do. In addition, in dehumidification mode with the compressor turned on, if the indoor temperature rises and the temperature obtained by subtracting a certain temperature from the detected indoor temperature exceeds the selected minimum dehumidification setting temperature for a certain period of time, Dehumidification operation is performed in dehumidification mode in which the minimum dehumidification setting temperature is lowered by a predetermined step.

When automatic operation is commanded among manual operation and automatic operation, a timer is activated to turn off the compressor 21 for three minutes. When the time is up, the indoor fan 14 is turned on with ultra-light wind and the outdoor fan 1 is turned on.
8 is also turned on. Immediately after turning on for one minute, the indoor humidity detection element 5 first detects humidity. Comparison circuit 8 compares whether this humidity is above or below 60%, and if it is above 60%, mode A in Figure 3 is selected, and 60%
If it is less than that, mode B is selected. In this mode B, the fourth
As shown in the figure, no dehumidification takes place. Next, it is assumed that in mode A, dehumidification I mode (lowest dehumidification set temperature Ts=23° C.) is selected.
Here, if the compressor 21 is on, the indoor temperature Tr
The temperature is higher than 23℃, and dehumidification (low air conditioning) is possible. If the indoor temperature Tr at this time is 27℃,
If Ts≦Tr−3 and this condition continues for more than 10 minutes, the cooling zone (Tr≧25℃, To≧25
℃), dehumidification is performed in dehumidification I mode. Next, when Ts = 23°C and Tr < 23°C, the compressor 21 is turned off, but when the off-time duration exceeds 10 minutes, the indoor fan 14 is turned on for 1 minute and restarted. Detects RH and enters dehumidification if RH≧60%. However, when Tr < 23°C, the dehumidification I mode cannot be fully operated, so the dehumidification is performed by converting to the dehumidification mode in which Ts is lowered to 21°C. In this way, the dehumidification set temperature Ts is varied according to the rise and fall of the indoor temperature Tr, and only dehumidification is performed without performing an excessive cooling action.
前記実施例では、Ts＝23℃の除湿モードと、
Ts＝21℃の除湿モードの２段階としたが、さ

必要な冷房作用をすることがない。"Effects of the Invention" Since the present invention is configured as described above, when the temperature condition changes drastically during operation, switching between the cooling and dehumidifying operation modes is possible without manually changing the mode. This is done automatically, so it can adapt to changes in the environment and provide a comfortable living condition. In addition, since the indoor humidity is detected and the dehumidifying operation is stopped when the humidity is below a certain level, unnecessary dehumidifying operations can be omitted and energy can be saved. Furthermore, the dehumidification mode is divided into multiple stages depending on the lowest set temperature, so even if the compressor is stopped when the room temperature drops, the dehumidification set temperature will automatically drop and dehumidification can continue. ,
Even when the room temperature rises, the set temperature is raised and dehumidified, eliminating unnecessary cooling.
