Climate solutions evaporative cooling, adiabatic humidification and programmable controllers energy saving solutions for data centers

Data center air-conditioning Data center air-conditioning is essential for the correct operation of Information Technology equipment: processing and storage devices produce considerable heat that needs to be removed in order to maintain optimum operating conditions. Energy saving through evaporative cooling and adiabatic humidification: integration and versatility Worldwide data center power consumption is estimated to be 30 GW, accounting for around 1.5% of the earth’s total electricity usage: as a result of this astonishing level of energy consumption, energy saving solutions are...

Evaporative cooling and adiabatic humidification The data center air-conditioning solution with the highest energy efficiency and lowest environmental impact evaporative cooling and eliminating inefficiencies. The outside air condition where mechanical cooling only is required is represented by the red area. Evaporative coolers, such as water spray atomizers, provide highly efficient cooling solutions with the added benefit of humidity control whilst ensuring substantial reduction in energy consumption and costs without any impact on maintenance costs. 90 Optimum control of the air80...

Direct free cooling + DEC and adiabatic humidification The solution that optimises the use of outside air, lowering temperatures in summer through direct evaporative cooling (DEC) and controlling humidity in winter, using the same unit Maximum free cooling and DEC efficiency Extension of the period in which free cooling can be used Precise humidity control The system comprises an AHU that introduces outside air in summer for free cooling, plus DEC when the outside conditions allow. The air is humidified and cooled providing approx. 680W/L cooling with a power consumption from just 4W/L....

Indirect air-side free cooling + IEC The solution that maximises free cooling, implementing indirect evaporative cooling without introducing outside air into the data center due to problems such as pollutants, or when humidity levels mean DEC is not feasible The system comprises an AHU that recirculates the air, cooling it via a heat recovery unit that exchanges heat with the outside air. This “secondary” air stream flows through the heat recovery unit without entering the data center. The evaporative cooler (2) reduces the “secondary” air temperature, while at the same time increasing its...

Indirect free cooling + IEC combined with CRAC The solution involving IEC combined with traditional air-conditioning technology using perimeter Computer Room Air Conditioners Air recirculation to avoid introducing contaminants Ideal solution for retrofits in existing data centres Humidity control with adiabatic humidification Redundancy with two separate systems The system comprises an AHU that recirculates the air, cooling it via a heat recovery unit that exchanges heat with the outside air. This “secondary” air stream flows through the heat recovery unit without entering the data center....

Indirect “water-side” free cooling + IEC The solution for saving energy through evaporative cooling, however without modifying the air flows inside the data center, using traditional air-conditioning technology The system comprises perimeter CRAC units that control supply or server room temperature and humidity. chillBooster, installed on the dry cooler or the condenser, evaporatively cools the air intake and guarantees considerable energy saving by lowering the average refrigerant circuit condensing temperature. In CRAC systems with water-side economizers, i.e. fitted with a water coil...

Steam humidification kit for close control units Controller for compressors with permanent magnet brushless motors (BLDC/BLAC). humiSonic Ultrasound humidification for close control units and fan coils Optimist Air can be effectively cooled by exploiting the evaporation of atomised water. 100 kg/h of water absorbs 69 kW of heat when evaporating, with power consumption of less than 1 kW. Inverters represent a cutting-edge solution for modulating fan speed. Flexibility, connectivity, integration, energy saving. Adiabatic humidifiers offer significant advantages in terms of precise and...
