Free cooling saves energy and operating expenses at Telecom sites, where the application of traditional air conditioners has resulted in very high energy costs. By using free cooling, the overall thermal management running expenditure can be reduced by up to 90%.
Free Cooling - how it works
Dantherm's Free Cooling solutions create a fine-filtered overpressure. Motorized dampers are recommended to ensure optimum airflow in the shelter and to prevent ambient air from entering the shelter or room.
Total heat management
The Dantherm Free Cooling solutions provide the option of total heat management in the shelter, as the system controls both connected heating and air conditioning systems. Even surveillance and alarms are part of the Free Cooling solution.
6th generation free cooling
The Free Cooling technology has been used by Dantherm for more than a decade and has been through 6 design generations resulting in related know-how build-up.
When choosing a cooling technology that utilizes ambient air to cool, it is important to understand the concept of delta t (Δt):
Δt = t internal - t ambient
The capacity is stated as e.g. 288 W/K. This means that by a difference in temperature of 1Kelvin = 1°C, the cooling capacity is 0,288 kW.
Example: Average ambient temperature: 20°C, desired internal temperature: 25°C = Δt = 5 (25-20).
Humidity in relation to Free Cooling is a frequently asked question. When using Free Cooling, you may apply humid and cold ambient air into an electronic enclosure to cool it down. When the humid ambient air meets the warm air in the enclosure, it is heated and the relative humidity will decrease - leaving no risk for condensation on the electronic equipment.
