◆ Special requirements for air conditioning units in the machine room:

As science and technology continue to advance, the requirements for data centers are becoming increasingly stringent. In response to the unique environmental demands of data centers, their air-conditioning systems and equipment must be specially configured to enhance indoor air quality and maintain optimal temperature and humidity levels. Precision air conditioners for data centers feature high heat loads, large airflow rates, year-round cooling capabilities, and continuous operation. They demand higher filtration levels and lower leakage rates. These systems are widely used in sectors such as finance, postal and telecommunications, television stations, oil exploration, printing, scientific research, and power generation, thereby improving the reliability and operational cost-effectiveness of computers, networks, and communication systems housed within data centers.

Features of precision air conditioners: 1. Small enthalpy difference and large airflow—suitable for applications with high heat load intensity, significant heat dissipation, and low moisture removal.

2. Strict Control: The air conditioner is equipped with a controller featuring a miniature microcomputer. This controller not only monitors both indoor and outdoor environments and automatically adjusts the temperature and humidity inside the room, but also boasts self-diagnostic capabilities. Additionally, the controller includes communication functions that enable online connectivity and coordinated operation among multiple units, as well as remote monitoring and control.

3. Year-round cooling: In winter, the air conditioner operates in cooling mode. By adjusting the condenser fan speed to stabilize the condensing pressure, the air conditioner can continue to operate fully even when outdoor temperatures drop as low as -20℃.

Combining the many advantages and latest technologies of today’s data center air conditioners, this product delivers unprecedented value to users in critical environments. It serves air-conditioned spaces with stringent requirements for temperature and humidity, offering a wide operating temperature range (-20℃ to 45℃) and enabling 24-hour, 365-day continuous operation. The product has undergone rigorous laboratory testing and been certified by authoritative national agencies, boasting the highest efficiency among similar products, the most energy-efficient refrigeration system, and the most stable and reliable operational performance. It represents a perfect integration of advanced design concepts and mature manufacturing processes.

▶ Box structure

The Tianxing precision air-conditioning unit series features an anodized aluminum alloy frame. The inner and outer panels of the cabinet are made of color-coated steel sheets, while the interior is insulated with high-pressure, biodegradable polyurethane foam. German CNC sheet-metal processing equipment ensures that both the inner and outer panels are smooth and free of welds, thereby eliminating unprotected cut edges, localized dust and water accumulation, and turbulence. This guarantees the unit’s superior corrosion resistance and cleanliness.

▶ Sealing material

To minimize air leakage and noise to the greatest extent possible, Tianxing has introduced a complete set of low-pressure sealing equipment from Conformani S.p.A. in Italy. The unit’s panel and inspection door areas now feature a proprietary liquid soft-foam sealing technology that replaces manual sealing methods, achieving truly seamless sealing. This significantly reduces air leakage and noise levels, ensuring high airtightness and an extended service life for the enclosure.

▶ Filter

Tianxing uses durable filter frames equipped with quick-clamping devices, making the replacement process even easier. We offer a wide selection of filters spanning from primary to high-efficiency levels. Our experienced design team also carefully tailors the appropriate filtration level and model based on the specific application conditions and customer requirements.

▶ Precise control

The controller of Tianxing Precision Air Conditioners can accurately detect changes in indoor operating conditions and control the unit’s operation. Its control accuracy is: temperature ±1.0℃ and humidity ±5%. For specially designed Tianxing high-precision air conditioning units, the current control accuracy can reach: temperature ±0.1℃ and humidity ±1%.

▶ Indoor fan

The indoor fan motor can be either a directly coupled fan or a belt-driven fan, both of which offer reliable operation, high efficiency, and low noise levels. The residual pressure outside the fan is adjustable between 50 and 400 Pa. Both the internal components of the fan and its connections to the unit’s structure feature flexible couplings—minimizing vibration to the greatest extent possible. For belt-driven fans, the pitch diameters of the motor and fan pulleys are adjustable, allowing for easy adjustment of the center distance between the pulleys. Additionally, the residual pressure outside the fan can be customized according to the user’s specific requirements.
