Abstract

PURPOSE:To provide comfortable air conditioning, when a room temperature is high, by automatically reducing the differential value of a temperature controller, elongating the time period of cooling operation, thereby performing quick dehumidifying action. CONSTITUTION:A compressor is turned ON and OFF in cooling cycles by the temperature controller and cooling operation and air blowing operation are repeated. Thus the room temperature is controlled in the air conditioning system. In this system, an electric control mechanism is provided so that the temperature difference between ''ON'' and ''OFF'' states of the temperature controller is small when the humidity in the room is high. For example, when the differential value A of the temperature controller is made to be 0.5 deg.C that is small value at the time of high humidity, the operating time period of the compressor becomes long in comparison with the case of differential value of 2 deg.C. Therefore the time period of the cooling operation becomes long and the quick dehumidifying action is performed.

Description

[Detailed description of the invention] The present invention relates to operation control of an air conditioner.

Temperature, humidity, and other factors that affect the human body's sense of comfort
For example, airflow is controlled in an air conditioner by repeatedly performing cooling operation and blowing operation using a temperature sensor and a humidity sensor. In conventional air conditioners, only the room temperature was controlled using a temperature controller, and the humidity was not controlled at the same time.However, recently, healthy cooling,
Comfortable air conditioning has become a necessity, and humidity control has become a necessity in addition to room temperature control. Figure 1 shows an example of conventional temperature control. As shown in Figure 111, in the case of high humidity, the set temperature is automatically lowered to lower the room temperature and increase the cooling operation time to dehumidify and improve comfort. We are conducting controls to improve this. As mentioned above, the conventional temperature-tube differential for controlling temperature and humidity is typically 1 to 2 degrees Celsius and is constant for each device. As shown in FIG. 2, when the room temperature reaches the set temperature, the compressor stops and the cooling operation is switched to the blowing operation, and the cooling operation does not resume unless the room temperature rises by the differential amount. Therefore, this eliminates the problem of moisture backflowing into the room during this time and the fact that it takes a long time to dehumidify because the air conditioner is running for a short time.

The present invention has been made in view of the above points, and it is an object of the present invention to provide an air conditioner that can quickly dehumidify and provide comfortable air conditioning when the indoor Oa degree is high.

In order to achieve the above object, the present invention uses a humidity sensor to detect high humidity indoors, automatically reduces the differential of the temperature controller, and lengthens the cooling operation time. It quickly dehumidifies air to provide comfortable air conditioning and is free of mold.

Hereinafter, the present invention will be explained in detail using an embodiment shown in FIG. FIG. 3 shows the operating mode of the temperature controller during high humidity. This is the case where the differential △ at high humidity is set to 0.5°C, but it can be seen that the operating time of the compressor, that is, the cooling operating time is longer than in the case of the differential of 2°C in Fig. 2. Since the system is configured as described above, by reducing the differential between the temperature and cylinder unit during high humidity changes, the cooling operation time at high temperatures, that is, the dehumidification time is not long, and the dehumidification is performed quickly. Even when the humidity temperature reaches the set temperature and the cooling operation is stopped, the differential of the temperature controller is small, so the cooling operation stop time is shortened, and moisture backflow into the room during that time is also reduced.
