Climate Control System Control Functions
The control function of the artificial climate chamber system The system carries out the following aspects of control and adjustment according to the various parameters collected by the data acquisition card.
1) Temperature control The system can be temperature-controlled to achieve temperature control in the morning, afternoon, the first half of the night, late at night and five in the morning. According to the specific use of artificial climate room, according to the actual situation to change the temperature change period.
2) Humidity control Humidity is an important state parameter in many industries, such as construction environmental engineering (such as air conditioning), weather, storage management (such as food, medicine), product processing (such as food, chemical industry), etc., and it is often required to carry out Monitoring and control. The humidity control of this system adopts the control of the dehumidifying equipment to ensure the constant humidity of the artificial environment.
3) Light control This system mainly controls the opening and closing of the shade screen to achieve the control of the light intensity. Actually, in the nursery and planting greenhouses, in order to enable the plants to get good light and avoid exceeding the light saturation point, shade screens are used to block the sunlight, and artificial lighting equipment can be turned on at night or on cloudy days through a control system. Normal daylight crops are artificially illuminated.
4) Control of carbon dioxide content The system can monitor the carbon dioxide content in the artificial environment in real time. When the content of carbon dioxide is higher than a certain value, it starts the ventilation motor, changes the wind in the artificial environment, and ensures the fresh air in the environment. If, in an agricultural artificial environment, a higher carbon dioxide content is required to increase the gas fertilizer, the carbon dioxide generator should be turned on when the carbon dioxide content is lower than the set value to ensure that the environment's carbon dioxide content reaches a predetermined requirement.
