Cooling is positioned close to the heat source and can be used with hot and cold aisle containment to reduce airflow cooling loss.","working_principle":"","features":["DC inverter compressor, indoor EC variable-speed fan, electronic expansion valve and variable-speed condenser fan provide stepless cooling capacity control and 30% energy savings.","Cooling close to the heat source, combined with hot\/cold aisle containment, reduces airflow cooling losses and improves air delivery and cooling efficiency.","Multiple fans operate at their optimum efficiency points and provide redundancy.","Intelligent controls adjust fan speed to cooling demand, substantially reducing fan energy consumption.","Cooling\/heating and constant-temperature-and-humidity configurations meet different application requirements.","Components from established brands provide high reliability, a design life exceeding ten years and low maintenance costs.","A 7-inch touchscreen and multiple temperature and pressure sensors display unit operating status for operation and maintenance.","High airflow and a small enthalpy difference meet equipment-room requirements for a high sensible heat ratio.","Uses R410A refrigerant.","Automatically restarts after power restoration and resumes the operating state used before the outage.","Standard RS485 communication interface; a communication protocol can be supplied.","Extensive self-diagnostics, alarms and protection functions support safe, reliable operation."],"applications":["Data centers (IDC)","Telecommunications equipment rooms","Medium and large computer rooms","UPS and battery rooms","Industrial control rooms","Power distribution rooms","Transformer rooms","Precision equipment workplaces"],"notes":["Air-cooled standard conditions: indoor return air dry-bulb temperature 35\u00b0C, wet-bulb temperature 21\u00b0C (27%RH);
