Furthermore, the EEV's high modulation capacity allows for a reduction in condensing pressure, consequently lowering energy consumption at night or during the colder months. During the warmer months, the valve generates savings of 4-5%, but when the reduction in energy consumption is taken into account, the annual savings exceed 15%.
Another crucial aspect is the DC compressor control system. The CAREL inverter can control the compressors in the new CRAC units, using a direct expansion system that modulates cooling capacity to achieve the required air temperature. The system also provides redundancy: having units operating at 75% capacity means a reserve of cooling capacity is available should a problem occur in another unit. This allows operation at partial load most of the time, resulting in energy savings of up to 25-30%.
The CAREL solution is completed with the new humiSonic direct ultrasonic humidifier. It is characterized by its low energy consumption (less than 80W per liter of atomized water), reliability (10,000
Operating hours when using demineralized water), accuracy (±1 to the set point), efficiency (1μm droplets that evaporate instantly), easy installation, and hygiene. Furthermore, it can be easily integrated into a BMS via an external signal or a serial connection using the Modbus protocol.
