As the digital economy develops rapidly, data centers serve as the core carrier of computing infrastructure, undertaking core functions including data storage, computing and transmission. Professional refrigeration and temperature control systems act as the lifeline for stable long-term operation of data centers, directly determining the PUE level of computer rooms, uninterrupted operation of core business and full-lifecycle O&M costs. HOLTOP room level air-cooled precision air conditioners address all pain points of computer room temperature control with comprehensive robust performance, adapt to diverse complex working conditions, and fully safeguard stable, efficient and low-carbon operation of computing equipment.
Precise Constant Temperature & Humidity Control
HOLTOP room level air-cooled precision air conditioners achieve a temperature control accuracy of ±1℃ and humidity control accuracy of ±5%. The units can adapt to dynamic load fluctuations in computer rooms and extreme high/low outdoor temperatures around the clock, forming closed-loop regulation of indoor environmental parameters. They maintain a stable constant temperature and humidity environment tailored for precision equipment all year round to ensure continuous and reliable operation of all types of devices.
Long-Term Stable Performance Under All Working Conditions
Equipped with high-performance hermetic flexible scroll compressors, HOLTOP room level precision air conditioners feature strong liquid slugging resistance, low operating vibration and low noise, fully meeting the silent operation standards of computer rooms. Integrated with multiple intelligent safety protection mechanisms including overvoltage, overcurrent, anti-freezing and overload protection, the units eliminate potential operational risks comprehensively. Optional low-temperature adaptation kits are available. The fluorine pump models can deliver stable cooling output even under extreme outdoor temperatures as low as -40℃. Capable of coping with severe cold, drastic day-night temperature differences and sudden load changes, the products are applicable to data center projects in various climate zones worldwide.
Multi-Dimensional Low-Carbon Energy Saving
Adopting a full set of energy-saving configurations, HOLTOP room level precision air conditioners systematically cut cooling power consumption and help data centers optimize PUE and reduce electricity expenses. Standard high-efficiency EC variable-speed fans maintain an energy efficiency of over 85% under low-speed steady operation for remarkable energy-saving effects. The refrigeration circuit adopts high-precision electronic expansion valves for accurate refrigerant flow regulation. The heat exchanger composed of high-fin inner-thread copper tubes and high-efficiency louvered fins greatly improves heat exchange efficiency and upgrades overall cooling performance. All models can be equipped with fluorine pump free cooling modules. During transitional seasons and cold nights, the compressors can be shut down while the fluorine pump system provides independent natural cooling. The power consumption under free cooling mode only accounts for 10%-20% of conventional compression cooling. The system maximizes the utilization of natural cold sources to reduce cooling energy consumption fundamentally, supporting data centers to realize low-carbon operation and lower PUE targets.
Integrated Intelligent Control & Management
Each unit is equipped with a 7-inch high-definition touch screen, which visually displays multi-dimensional operating data such as temperature, humidity, power consumption and unit status. Built-in power-off memory chips fully retain all data and parameters after unexpected power failure and restart. Supporting mainstream industrial communication protocols including MODBUS, TCP/IP and SNMP, the units can seamlessly connect with computer room monitoring platforms. Up to 32 units can be networked and linked in a single room to realize automatic rotation of primary/standby units and intelligent load distribution. Combined with advance fault early warning and autonomous fault diagnosis functions, the system identifies hidden equipment failures in advance, shifting passive maintenance to predictive operation and maintenance, drastically cutting O&M man-hours and labor costs.
Flexible Adaptation to All Scenarios
The units support mainstream air supply and return modes, compatible with various computer room layouts including raised floor air supply, ceiling air supply and direct cabinet cooling. The compact integrated structure takes up less floor space and fits customized computer room layouts flexibly. The products are widely applicable to new standard data center construction, equipment replacement and expansion of legacy computer rooms, as well as partial cabinet micro-zone temperature control renovation. Large-scale reconstruction of infrastructure is not required, delivering strong adaptability and high project implementation efficiency.
Focusing on the core demands of long-term O&M, low-carbon efficiency improvement and stable safe operation of data centers, HOLTOP room level air-cooled precision air conditioners deliver powerful capabilities in precise temperature control, reliable quality, energy conservation and intelligent management. They fully protect the stable operation of computing infrastructure, and provide a one-stop reliable temperature control solution for data centers across all industries to boost efficiency, cut costs and optimize PUE in the long run.
