YMK's SCA.UES Series Room-level VRF Refrigerant Energy-saving Precision Air Conditioner is an energy-saving air conditioner tailored for server rooms of ultra-high energy efficiency with high return air temperature. The unit uses environment-friendly R410A cold medium, and it can adjust cooling capacity and air volume output in real-time according to thermal load conditions. It also features a pump energy-saving module, intelligently adjusting between three cooling operation modes: high-efficiency cooling, dual-power energy-saving, and natural energy-saving, based on environmental temperature. This maximizes the use of natural cool sources and reduces the PUE value for the server room.
Core Value
Environmental friendliness:
• The unit uses environment-friendly R410A cold medium, adopts outdoor variable frequency fan and indoor EC silent fan, and implements precise control of electronic expansion valve and low frequency startup of compressor, eliminating the noise pollution and potential risks to damage the atmosphere;
Variable load regulation:
• Fully variable frequency design, intelligently adjusting cooling capacity based on load; dual system and dual variable frequency compressor and Refrigerant, for partial load operation, providing more timely load response; low startup current, minimizing damage to electrical distribution equipment;
AI-assisted energy efficiency management:
• Indoor EC and outdoor variable frequency fan speed regulation, dynamic opening control of electronic expansion valve, and thermal and moisture load and air supply temperature control matching with dual-compressor stepless frequency modulation; the air supply temperature control is selected as needed in the server room to isolate cold and hot aisles and intelligently switch among three operating modes;
Fault self-diagnosis:
• When the unit is not operating in normal condition, the alarm information will be prompted, and the control system will conduct fault self-diagnosis based on the alarm information, and inform the operation and maintenance personnel of the possible causes. Later, the operation and maintenance personnel will check, confirm and solve the problems accordingly.
Application Scenarios
• Medium- and large-sized data centers with ultra-efficiency requirements
• Green server rooms with the air supply temperature control requirement for enclosed cold aisle
• Data centers in water shortage area with the requirement for ultra-high annual energy efficiency ratio (EER)
• Green data centers that are especially suitable for northern regions
