A holistic approach is needed to find the appropriate energy-efficient climate control solution for your system, because there are numerous aspects to consider. What are the ambient conditions at your system’s location, for example? Is it humid? Dusty? Hot? And what are the actual requirements in terms of cooling output? Factors such as the type of installation (free-standing or integrated), the heat dissipation (passive or active) and the permissible noise level also need to be taken into account.
Did you know...
... that correct climate control can significantly lengthen the service life of components located in the enclosure?
The growing packing density in enclosures can lead to a huge increase in the heat loss!
As a general rule of thumb, a 10 °C rise in operating temperature halves the service life and doubles the failure rate.
Overview of types of climate control based on ambient conditions
The different types of climate control have a variety of features and offer a wide range of benefits.
Units for cooling with ambient air are ideal for dissipating heat loads with excellent cost-efficiency. The pre-requisite is a relatively clean ambient air at a temperature that is lower than the desired temperature inside the enclosure.
Requirements:
-
Relatively clean ambient air
-
Ambient temperature lower than the desired temperature inside the enclosure
Benefits:
- Particularly energy-efficient
- Fast, cost-effective installation
- No customer infrastructure required
Cooling units keep the temperature inside the enclosure at a constant level, regardless of the ambient temperature. The air routing meets individual requirements. Two separate circuits prevent the ingress of dust into the enclosure.
Requirements:
- Also suitable for use in warm or dusty ambient air
- Ambient temperature at least as high as the desired temperature inside the enclosure
Benefits:
- Two separate circuits prevent the ingress of dust into the enclosure
- The temperature inside the enclosure is kept at a constant level
- Excellent energy efficiency thanks to the innovative Blue e+ series of cooling units
Efficient liquid cooling is used wherever a high cooling load is required – for example, in process and machine cooling or if using air/water heat exchangers to dissipate heat losses from enclosures. Spatial separation between cooling production and process cooling can be achieved with liquid cooling systems.
Requirements:
- Also suitable for use in corrosive or oily ambient air
- Ambient temperature can be higher or lower than the temperature inside the enclosure
- A supply of cooling water must be ensured at the installation site
Benefits:
- Exceptional temperature accuracy (constant water temperature)
- Can cool both enclosures and machine tools
- Suitable even for extremely high ambient temperatures
- The heat exchanger and chiller can easily be kept separate, so no waste heat is generated in the room
Condensation poses a particular risk for control electronics, especially with outdoor siting. Having a range of output categories ensures the correct thermal output is always available.
Requirements:
- No requirements relating to the ambient air/temperature outside the enclosure
Benefits:
- Distributes warm internal air evenly
- Avoids subnormal temperatures in switchgear
- Preventing condensation protects against corrosion
Superbly coordinated components tailor the climate control components perfectly to your specific requirements – from targeted air routing and precise control of equipment to the appropriate consumables.
Benefits:
- Monitoring, control and individual air routing can further increase the efficiency and reliability of climate control components
