Air-conditioning technology for safe, efficient and sustainable indoor farming

Air-conditioning is the basis for optimal growth conditions for plants and insects

Unlike cultivation in greenhouses, plants in indoor farming are not exposed to natural light and are instead cultivated using LED lights under optimized conditions. These growth conditions enable high yield of a consistent quality to be achieved all year round.

As well as lighting and irrigation, air-conditioning plays a decisive role in indoor farming. Lettuce, herbs or even cannabis will only grow optimally when temperature, humidity and airflow are adjusted with precision. With our tried-and-tested, efficient air-conditioning solutions, we ensure the necessary conditions for plants in indoor farms at all times. We also offer special solutions for insect breeding.

Challenges

Controlling temperature, humidity and CO2 levels

Every plant and every species of insect has different requirements when it comes to humidity, temperature and the CO2 levels in the air. With our air-conditioning, we manage the cooling, heating, dehumidification and ventilation of indoor farms in such a way that the desired climate conditions prevail precisely at all times.

Using energy-efficient air-conditioning technology

Air-conditioning in the large spaces used in vertical cultivation, indoor farming and insect breeding is energy-intensive and thus a relevant costing factor. In order to keep costs as low as possible, we work with energy-efficient components and intelligent management systems.

Complying with hygiene standards

In addition to climatic conditions, air hygiene has also an important role to play in producing healthy plants and guaranteed harvests. For this reason, we plan and realize air-conditioning technology for indoor farms, including the appropriate filter levels, also in compliance with the hygiene requirements of VDI 6022.

Enabling flexibility

We develop flexible, scalable and versatile solutions for the air conditioning of indoor farms, vertical cultivation and indoor insect breeding. This enables operators to easily switch to other plants and insects or extend the cultivation spaces according to their needs.

Application Areas

Indoor farming
Controlled-Environment Agriculture (CEA)
Vertical cultivation
Urban cultivation
Indoor cannabis cultivation
Indoor insect breeding

Our Solution

Dependable and tailored air-conditioning technology for plant cultivation and insect breeding in indoor farms

As a leading specialist for air-conditioning technology, we also have many years of experience in planning and realizing air-conditioning solutions for indoor farms and vertical cultivation.

For these applications, we use compact, high-performance and flexibly implementable air-conditioning devices and solutions for intelligent airflow.

We thus enable the needs-based processing of the air. The precise management and monitoring of temperature, humidity and CO2 levels is conducted via our intelligent management systems. All devices used comply with the hygiene standards of, for example, the VDI 6022.

FAQ

Which technologies are suitable for the air conditioning of indoor farms?

Automated climate control systems are ideal for the air conditioning of indoor farms and vertical cultivation spaces. These monitor temperature, humidity and CO₂ concentration in the air in real time, quickly adjusting these as necessary to the desired control value.

Energy-efficient air conditioning units and custom-selected sensors ensure precise control of climate conditions at all times. In addition to producing and maintaining the optimal conditions for growth, intelligently used control and regulation technology also helps to minimize energy consumption.

What is the optimal temperature for plant growth?

The perfect temperature for fast, healthy growth will depend on the plant. Generally speaking, the ideal temperature is between 20 and 30 °C.

Most plant metabolic processes run efficiently and achieve correspondingly good growth in this temperature range. In order to achieve the best and most consistent yields, it is also important to avoid temperature fluctuations, as these can affect plant growth and thus the yield.

What is the optimal temperature for insect breeding?

The perfect temperature for fast, healthy growth will depend on the species of insect. Generally speaking, the ideal temperature is between 25 and 30 °C.

Most insect metabolic processes run efficiently and achieve correspondingly good growth in this temperature range. In order to achieve the best and most consistent breeding results, it is also important to avoid temperature fluctuations, as these can affect insect growth and thus the breeding result.

What has to be taken into consideration when it comes to humidity in greenhouses and indoor farms?

Humidity control is crucial for plant growth and insect breeding. Hygrometers check this regularly to keep humidity within the optimal range at all times. 

The control and regulation technology uses the results of the measurement and controls the components for humidification and dehumidification in such a way that the humidity is increased or reduced to levels appropriate for plants and insects. Good ventilation with regulated air circulation is also important here in order to distribute the moisture evenly and prevent mold growth.

How can the CO₂ concentration in an indoor farm be monitored and controlled?

Monitoring and controlling CO₂ concentrations is important because plants absorb CO₂ during photosynthesis. CO₂ sensors measure the CO₂ concentration continuously. If this drops, the air supply is automatically increased via the control and regulation technology in order to restore the desired target value. An adequate supply of CO₂ can significantly increase plant growth and thus yields.

What role does air circulation play in the air conditioning of indoor farms?

Good, draught-free air circulation is crucial to ensure consistent temperature and humidity conditions in indoor farms and vertical farming. It helps to avoid the build-up of hot or cold spots and ensures that all plants and insects are evenly supplied with fresh air.

Fans and special air circulation systems can be used to keep the air moving and prevent the formation of mold and other moisture problems without exposing plants and insects to stress from draughts.

Which hygiene standards must be complied with in the air conditioning of indoor farms?

High hygiene standards should be maintained in the air conditioning of indoor farms in order to avoid pests, contamination and diseases of plants and insects.

Standards such as VDI 6022 define the requirements for the hygiene of ventilation and air conditioning systems. Regular cleaning and maintenance of air conditioners is also necessary to ensure that no mold spores or other pollutants are released into the air.
