Understanding the Cooling Challenge in Modern Data Centers
Data center operators face a continuous demand for stable, precise cooling across server halls, switchgear rooms, and auxiliary equipment areas. Among the industries covered by Jiangsu Obuy New Energy Development Co., Ltd., data centers are explicitly listed alongside rail transit, hospitals, warehousing, and other facilities that depend on uninterrupted temperature management. Data center operators are also identified as a distinct customer type that this enterprise serves, reflecting a recognition that computing infrastructure has specific cooling requirements that differ from standard commercial air conditioning.
The core challenge for any facility housing dense electronic equipment is maintaining consistent temperature control while managing energy consumption and water usage responsibly. Obuy, operating under the Obuy and YIJIAREN brand identities, addresses this through a portfolio of chillers and evaporative cooling units engineered around vapor-compression refrigeration cycles, wide operating ranges, and intelligent monitoring systems.
The Technology Enabling Ultra-Low Temperature Performance
At the foundation of this capability is a vapor-compression refrigeration cycle supported by scroll, screw, centrifugal, or piston compressor options, allowing equipment selection to match specific load and duty requirements. For applications demanding operation in colder ambient conditions, EVI (Enhanced Vapor Injection) technology enables stable performance from -30°C to 45°C on heat pump and air-source units, extending the usable range well beyond conventional refrigeration equipment.
Supporting components are engineered for durability under continuous duty. Hydrophilic aluminum fin coils on air-cooled units resist dust accumulation and frost formation, while anti-scaling and anti-corrosion water-cooled heat exchangers are built to withstand varied water quality conditions. For compressor-free applications, evaporative wet pad cooling media deliver high evaporation efficiency, dust resistance, and easy cleaning.
Operating Ranges Across the Product Portfolio
Temperature performance varies by product category, giving facility planners options suited to their specific environment:
- Air-cooled chillers operate from -15°C to 45°C.
- Water-cooled chillers operate from -10°C to 45°C.
- Heat pump chillers, equipped with EVI vapor injection, operate from -30°C to 45°C.
- Evaporative cooling units operate from -5°C to 45°C.
Across chiller product lines, chilled water delivery ranges from 5°C to 35°C, with temperature control accuracy held to ±1°C — a precision level that matters directly to facilities where thermal stability affects equipment reliability.
Chiller and Cooling Solutions Suited to Data Center Environments
Box Type Air-Cooled Industrial Chiller with Built-In Water Tank and Pump
The 3 HP box-type air-cooled industrial chiller integrates a water tank and pump within a compact footprint, eliminating the need for separate external components. Its high-efficiency condenser and compressor deliver strong heat exchange performance, while anti-scaling and anti-corrosion components allow adaptation to varied water quality. The unit uses an eco-friendly refrigerant, incorporates intelligent temperature control and fault self-diagnosis, and supports remote monitoring. It operates across a wide range of -10°C to 45°C, achieves a COP of 3.5–6.5 with energy consumption reduction of over 20% compared to standard air-cooled chillers, maintains ±1°C temperature control accuracy, and delivers stable chilled water from 5°C to 35°C. Its listed industry adaptations include data centers alongside chemical processing, pharmaceuticals, electronics manufacturing, new energy battery testing, and food processing cold storage.
Evaporative Cooling Industrial Air Conditioner
The 5 HP evaporative cooling industrial air conditioner takes a different approach, operating entirely without a compressor. Water evaporation cooling is delivered through fresh air unit, air handling unit, or chiller unit configurations, with direct evaporative cooling suited to arid regions and indirect evaporative cooling available where humidity addition must be minimized. High-efficiency wet pad evaporative media provide strong evaporation efficiency with dust resistance and easy cleaning, and the simple, compressor-free structure keeps maintenance costs low. The unit operates from -5°C to 45°C, achieves a COP of 4.5–6.0, reduces temperature by 5–15°C while maintaining a 25–28°C comfort range, and delivers 5–8 air changes per hour with dust filtering. Compared to conventional air conditioning, it cuts energy consumption by over 60% and operates with zero carbon emissions. Its industry adaptation list explicitly includes data centers, in addition to rail transit, hospitals, textile factories, and agricultural greenhouses, with particular suitability for arid and water-scarce regions.
Intelligent Monitoring and Low-Maintenance Operation
Across its product lines, Obuy applies intelligent temperature control, fault self-diagnosis, and remote monitoring, allowing facility teams to track performance and address issues without constant on-site supervision. Maintenance demands are kept low by design: air-cooled units require only condenser fin dust cleaning and do not need a water treatment system. Equipment protection is also built in, with an IPX4 outdoor protection rating applied to heat pump chiller frames, and dust and splash resistance ratings referenced on air-cooled units to support reliable operation in varied installation environments.
Certified Quality Backed by Two Decades of Engineering Experience
Jiangsu Obuy New Energy Development Co., Ltd. has obtained ISO9001, ISO14001, and ISO45001 management system certifications, along with CCC and CE certifications, providing third-party assurance of quality, environmental, and occupational health and safety management practices. The company has delivered over 1,000 energy-saving solutions and project cases, including cooperation with Fortune Global 500 companies, foreign-invested enterprises, central state-owned enterprises, and other state-owned enterprises. Backed by 20 years of engineering experience, the company provides technical guidance, installation, construction, commissioning, and after-sales services, supporting customer goals of low carbon operation, energy saving, consumption reduction, and emission reduction.
Selecting the Right Configuration for a Data Center Project
Flexible installation options — including monoblock, split, skid-mounted, and box-type configurations with built-in water tanks and pumps — allow data center operators to match equipment to site conditions. Air-cooled plug-and-play units require only power supply and chilled water pipe connections, supporting rapid deployment where space or water access is limited. Skid-mounted systems with pre-piped, ready-to-connect interfaces further shorten installation time and reduce civil works, which can be valuable for phased data center expansions or retrofit projects.
For data center operators evaluating cooling infrastructure, the combination of wide operating temperature ranges, ±1°C control accuracy, intelligent diagnostics, and certified quality management positions Obuy as a sourcing option worth including in technical evaluations. Whether the priority is a compact, self-contained box-type chiller or a compressor-free evaporative cooling system suited to water-scarce regions, the underlying engineering — vapor-compression cycles, EVI-enabled low-temperature operation, and corrosion-resistant heat exchangers — reflects a product platform built around the practical demands of continuous, precision cooling.
