The present invention relates to an automatic environmental control system capable of controlling temperature and humidity to provide a comfortable environment for human living or to provide an appropriate environment for growing crops.

The proportion of temperature and humidity in human living is sometimes as absolute as air, and dominates many of our surroundings.

In addition, the effects of temperature and humidity on the manufacturing process of various industrial products or the growth or production of agricultural products that provide convenience of life are often not negligible.

In general, providing the optimal conditions for growing crops by appropriately controlling the temperature and humidity of the greenhouse during greenhouse cultivation has emerged as a very important factor from the development of the crop to the harvest.

In addition, agricultural products harvested from each household in rural areas are stored in private storage warehouses or joint management and cultivation rooms such as agricultural cooperatives, and are waiting for drying or shipping.

The harvested produce stored in these management and cultivation rooms must be stored for a long time or be dried before being shipped in a timely manner. Therefore, proper temperature and humidity must be maintained inside the storage management and drying room. If the temperature and humidity are not uniform, the stored agricultural and marine products are deteriorated, and if the temperature and humidity inside the drying room are not properly adjusted, the deterioration due to overdrying and rapid drying causes a huge loss to the profits of the farming and fishing villages.

5) Detailed menu tree. The following menu tree has been described in detail with “t2” as an example, and the operation method and procedure are the same for t0 and t1.

You can do

In the high temperature operation mode t0, when the temperature value input from the temperature sensor 100 is equal to or higher than the set t0 temperature, 100% of the circulation fan 310 and the exhaust fan 320 are output, and the input value from the temperature sensor 100 is If it is less than "t0", the high temperature operation mode is released.

The constant temperature operation mode t1 operates when the input value from the temperature sensor 100 is between "t0" and "t1". At this time, the exhaust fan 320 is in an OFF state, and the circulation fan 310 operates at a speed and a type set by a user.

Referring to FIG. 9, the low temperature operation mode t2 is an operation mode linked to the hot air heater or the hot air sensor 330 and operates only when all of the following conditions are satisfied. The input value from the temperature sensor 100 is "t2" or less, the season mode is set to winter, and the input value from the hot air sensor 330 is 40 degrees or more. If any one of the above three conditions is not satisfied, the low temperature operation mode is not entered. If any one of the above conditions occurs during the low temperature operation mode, the low temperature operation mode is departed.

To describe the seasonal mode in more detail, there are a winter mode and a summer mode, which are the activation parameters of the low temperature operation mode. If winter is selected, the low temperature operation mode is activated, and the winter LED is turned on in the status display lamp 520. If summer is selected, the low temperature operation mode is deactivated and the winter LED of the status display lamp 520 is turned off.

Next, a high humidity operation mode, which is a method of operating in a high humidity state, will be described in detail with reference to FIG. 10.

When the temperature condition is in the constant temperature operation mode (between t0 and t1) and the stop mode (between t1 and t2), when the input value from the humidity sensor 200 becomes higher than the user set humidity value, the circulation fan 310 outputs 100%. After the operation, the discharge fan 320 is output ON, the operation of the circulation fan and the discharge fan after entering the high humidity operation mode is determined according to the operating time set value and humidity conditions by the user.
