Product Introduction
Designed for mission-critical environments, this 104.6kW room air conditioner uses an N+1 backup configuration to maintain cooling continuity. During maintenance or an unexpected shutdown of one unit, the remaining equipment is capable of taking over the full heat-removal demand, reducing the risk of temperature escalation in the room. The high sensible heat ratio makes it particularly appropriate for communication backbone rooms where electronic equipment produces a concentrated sensible heat load, while 24/7 operation supports uninterrupted service.
Energy Efficiency
- A high-volume-airflow, low-temperature-differential operating concept provides effective heat removal with reduced power consumption.
- The flexible scroll compressor combines smooth operation with efficient compression performance.
- A large-area fin-and-tube evaporator improves the exchange of heat between the refrigerant and air stream.
- Carefully refined air-path geometry minimizes pressure loss, electrical consumption, and sound output.
High Reliability
- Built for round-the-clock, year-round duty, with a specified design lifetime of 10 years.
- Every accessory is subject to strict quality checks and functional testing to support reliable field operation.
- The PTC heater offers a stable and safe heating solution when auxiliary heat is required.
- A range of protective controls helps the equipment continue operating safely and reliably.
Space-Saving Design
- The modular unit architecture supports flexible combinations for different project layouts.
- Return-air options can be selected to match the airflow organization and spatial conditions of the site.
- An optimized enclosure occupies less installation space without compromising serviceability.
- All major maintenance activities can be carried out from the front, helping conserve service-area space.
Intelligent Control
- The large Chinese/English LCD screen gives operators a direct view of equipment operation, component conditions, temperature, and humidity.
- A purpose-built controller for precision temperature and humidity regulation uses PID technology to maintain stable conditions.
- Alarm handling, equipment protection, and master diagnostic functions provide comprehensive operating supervision.
- RS485 connectivity supports remote data exchange, multi-unit networking, and centralized group management.
Typical Applications
- Small to Medium Server Rooms & Data Centers
- UPS and Battery Storage Rooms
- Telecommunication Base Stations & 5G Hubs
- Medical Imaging Suites (MRI/CT)
- Industrial Automation & PLC Control Rooms
