Product Overview
Nuodian CBS Series (also referred to as BS Series) small precision air conditioners are precision temperature control products specifically designed for small to medium-sized data center environments, providing stable and reliable precision temperature and humidity conditions for small to medium-sized data centers. This series of air conditioners features large airflow, ample cooling capacity, high sensible heat ratio, high energy efficiency ratio, and high reliability, ensuring 365 days a year, 24 hours a day uninterrupted operation for small to medium-sized data centers.
This series of air conditioners can be used in data rooms, small to medium-sized data centers, substations, switching stations, storage rooms, testing rooms, 4G/5G telecom base stations, large-screen equipment rooms, and other spaces with high requirements for temperature and humidity control. The cooling capacity ranges from 6kW to 20kW, and multiple types are available: cooling only, cooling with electric heating, cooling with humidification, and constant temperature & humidity models to meet different environmental control needs.
Airflow configuration: F (front upper supply air) + D (bottom return air)
Standard conditions: Return air dry-bulb 24°C, 50% RH, outdoor condensing temperature 35°C

 

Key Advantages
1. High Sensible Heat Ratio Design - Ideal for Data Center Loads
The product adopts a design featuring large airflow, small temperature differential, and high sensible heat ratio, with a sensible heat ratio exceeding 90% - perfectly matching the high sensible heat load requirements of data center equipment. Temperature control accuracy: 17°C - 28°C ±1°C, humidity control accuracy: 40% - 60% ±5%, providing a stable temperature and humidity environment for the data room.
2. Premium Components - Efficient & Reliable

• High-efficiency compressor: Uses world-renowned brand high-efficiency compressors, continuous compression with no reciprocating parts, low failure rate.
• Electronic expansion valve: Precisely adjusts refrigerant flow according to operating conditions, fast response, high accuracy.
• EC fan: Automatically adjusts speed based on cooling load and changes, ensuring control accuracy while reducing fan energy consumption. During dehumidification, the EC fan works with the electronic expansion valve to increase dehumidification capacity, reducing wasteful energy compensation from excessive electric heating caused by low temperatures during dehumidification - highly energy efficient.
• Stepless speed control outdoor fan: Adjusts speed according to refrigeration system pressure, reducing system pressure fluctuations, improving operating stability, and lowering overall energy consumption.

3. Intelligent Networking - Overall Energy Savings
The control system features group control functionality using a highly reliable CAN bus, enabling centralized control of up to 32 units. Functions include duty standby, competition prevention, hot standby, and failover backup, achieving overall energy savings for the data center.
4. Eco-Friendly Refrigerant
The refrigeration system uses R410A refrigerant, meeting modern environmental standards.
5. Stable & Reliable - Multiple Protections

• All key components are world-renowned brands, tested under extreme conditions in the lab for reliable operation.
• Comprehensive alarm protection and self-diagnostic records: power protection, water leakage protection, temperature/humidity excursion alarm, dirty filter alarm, system abnormal protection, auto-protection, and other alarm protections.
• Intelligent auto-restart: After power failure, the unit automatically restores operation using the parameters set before power loss. The start-up delay is adjustable to avoid power grid impact from simultaneous startup of multiple units in the same room.
• Standard RS485 interface with free communication protocol for integration into power and environment monitoring systems for remote monitoring.
• Optional low-temperature kit and long-pipe kit to ensure reliable operation in harsh installation conditions.
• Dual-speed fan motor: Provides fast acceleration and high humidity control accuracy.

6. Intelligent Control & Easy Maintenance

• 4.3-inch color touch screen: Real-time display of component operating status, runtime, air conditioner operating time, active alarms, historical alarms, temperature/humidity trends, etc.
• Multi-level password protection: Different access rights for different personnel, preventing unauthorized parameter changes.
• Intelligent alarm classification: Different alarm signals based on severity, facilitating quick problem identification.
• Remote monitoring: Via RS485 interface, supports remote setup and monitoring of unit operating status and alarm information.
• PTC electric heater: Semiconductor positive temperature coefficient characteristics - no red-hot surface, with safety protection for safer operation.
• Lightning protection.
• Threaded quick-connect fittings: On-site installation requires no brazing - fast and convenient.
• Optimal air supply method can be matched according to site conditions; axial fan or humidification functions can be selected as needed.
