Greenhouse Climate Control Systems: The Key to Modern Greenhouse Farming

In modern agriculture, greenhouse management offers the opportunity for uninterrupted production throughout the year thanks to controlled environmental conditions. However, at the basis of successful greenhouse management lies precise climate control. Greenhouse climate control systems protect plant health and maximize yield by automatically managing critical parameters such as temperature, humidity, CO2 level, and ventilation.

In this guide, we will examine in detail the working principles, components, advantages of greenhouse climate control systems, and Esular‘s smart greenhouse solutions.

Esular Greenhouse Climate Control Systems

What is a Greenhouse Climate Control System?

A greenhouse climate control system is an integrated technology that controls temperature, humidity, carbon dioxide level, and air circulation to provide optimum growth conditions for plants grown in the greenhouse. These systems continuously monitor greenhouse conditions through sensors and perform automatic interventions based on determined parameters.

Basic Working Principle: Multiple sensors placed inside the greenhouse collect real-time environmental data. The central control unit analyzes this data and automatically activates or deactivates climate control equipment such as windows, fans, heaters, or fogging systems when there is a deviation from ideal values.

Modern greenhouse climate control systems can also take proactive decisions by considering weather forecasts using artificial intelligence-supported algorithms. For example, if it is predicted that the temperature will drop at night, the system can start heating in advance.

Basic Components of a Greenhouse Climate Control System

An effective greenhouse climate control system consists of various components working in harmony with each other:

1. Sensor Systems

Temperature and Humidity Sensors: Measures temperature and humidity levels at different points inside the greenhouse. Multi-point measurement helps ensure homogeneous conditions in all areas of the greenhouse.

CO2 Sensors: Monitors the carbon dioxide level that plants need for photosynthesis. Esular’s wireless CO2-humidity-temperature sensors perform precise measurements with NDIR (Non-Dispersive Infrared) technology.

Light Sensors: Measures the amount of natural light entering the greenhouse and provides control of shading systems. PAR (Photosynthetically Active Radiation) sensors measure the light spectrum that plants can use.

Outdoor Environment Sensors: Monitors parameters such as outdoor air temperature, wind speed and direction, and precipitation amount, allowing the system to make proactive decisions.

2. Ventilation and Window Control Systems

Greenhouse ventilation is one of the most important pillars of climate control. Esular’s smart greenhouse window control panel automatically opens and closes side and roof windows by wirelessly controlling AC asynchronous motors.

Features:

Single or double window control options
Gradual opening and precise position control
Automatic closing safety based on wind speed

3. Temperature Control Systems

Heating Systems: Prevents the greenhouse internal temperature from falling below the minimum level required for plant development. Heating options based on natural gas, electricity, biomass, or geothermal energy sources can be used.

Cooling Systems: Fogging, evaporative cooling, or fan-pad systems are used to reduce the greenhouse internal temperature during high-temperature periods.

Circulation Fans: Ensures homogeneous air distribution within the greenhouse, preventing the formation of hot and cold air pockets. It reduces the risk of disease by removing water vapor from plant surfaces.

4. Humidity Control Systems

Fogging Systems: Sprays water into the air by dividing it into micron-sized droplets via high-pressure pumps. While these droplets evaporate, they absorb heat, providing both cooling and humidification.

Humidifiers: Used to balance humidity levels that drop due to heating, especially in winter months.

Dehumidification Systems: Reduces the humidity level with ventilation or heating in cases of excessive humidity. It minimizes fungal disease risks by preventing condensate water accumulation.

5. CO2 Enrichment Systems

Providing sufficient carbon dioxide levels for plant photosynthesis is of critical importance. In closed greenhouse conditions, CO2 concentration can drop rapidly. Optimal levels (usually 800-1200 ppm) are maintained with CO2 generators or liquid CO2 systems.

Advantages of Greenhouse Climate Control Systems

Modern greenhouse climate control systems provide numerous advantages to greenhouse operators:

Energy Saving

Thanks to smart algorithms, heating, cooling, and ventilation systems are activated only when necessary. It has been observed that up to 40 percent energy savings are achieved in real field applications. Sensor-supported control eliminates energy waste experienced in manual management.

Yield Increase

Plants growing in ideal conditions increase both product quantity and quality. **Up to 35 percent yield increase** can be achieved by preventing temperature stress, optimizing photosynthesis, and balanced humidity control.

The controlled environment accelerates the growth cycle of plants and offers more harvest opportunities within the year. The ability to produce out of season allows for more benefit from market prices.

Labor Savings

Thanks to automation, manual intervention requirements decrease dramatically. Processes such as opening-closing windows, adjusting heaters, and irrigation control are performed automatically. This provides businesses with up to 60 percent labor savings.

Employees can focus on more strategic tasks such as plant health monitoring, harvest planning, and marketing instead of routine operations.

Disease and Pest Control

Maintaining optimal humidity and temperature conditions eliminates the suitable environment for the development of fungal diseases. Especially the prevention of condensate water accumulation on the leaf surface minimizes diseases such as powdery mildew and rot.

Good air circulation makes it difficult for harmful insects to settle and reduces the use of chemical pesticides.

Remote Monitoring and Control

Thanks to the Esular mobile application, greenhouse managers can monitor greenhouse conditions in real-time from anywhere in the world and intervene if necessary. Alarm notifications ensure immediate awareness in critical situations.

Analysis of historical data allows for the determination of seasonal trends and strategic planning for future production periods.
