Technical Parameters
| Model | Power (kW) | Rotating speed (rpm) | Air Delivery (m3/min) | Shaft power (kW) | Specific power (kW/m3/min) | S.F. | Dimension(mm) | Weight(kg) |
| AB-420 | 37 | 2950 | 6.2 | 38.2 | 6.1 | 1.03 | 480*350*280 | 109 |
High-Efficiency Scroll Compressor(s):
At its core, the unit utilizes one or more advanced scroll compressors. This technology is known for its exceptional reliability, smooth and quiet operation, and high energy efficiency across a broad operating range compared to older compressor types.
Enhanced Heat Exchangers:
Air-Side Coils: Feature a V-type or cross-fin design with hydrophilic aluminum fins and inner-grooved copper tubes. This design maximizes heat transfer efficiency, improves drainage, and resists dirt accumulation.
Water-Side Heat Exchanger: Employs a high-efficiency shell-and-tube design, ensuring effective heat exchange between the refrigerant and water circuit with minimal pressure drop.
Advanced Intelligent Control System:
A sophisticated microprocessor-based controller is standard. It features a clear LCD display for real-time monitoring of all operational parameters (temperatures, pressures, statuses).
It includes comprehensive diagnostic capabilities and a full suite of protective functions (high/low pressure, anti-freeze, phase loss, compressor overload, etc.) to ensure safe and reliable operation.
Standard support for communication protocols like Modbus (RS-485) or optional BACnet allows for seamless integration into Building Management Systems (BMS) for centralized monitoring and control.
Robust and Durable Construction:
Built for outdoor installation, the unit features a heavy-duty galvanized steel chassis with a corrosion-resistant powder-coated finish. Key components are often from internationally renowned brands, ensuring longevity and reliability.
Environmentally Friendly Refrigerant:
Typically uses R-410A or other modern, environmentally responsible refrigerants with zero ozone depletion potential (ODP).
Proven Reliability: Built around a robust single scroll compressor known for long service life.
High Full-Load Efficiency: Excellent COP values under design conditions.
Dual Functionality: Provides both cooling and heating, offering a versatile solution.
Comprehensive Control and Protection: Advanced controller with a full suite of safety features to protect the investment.
Rugged Construction: Designed for reliable outdoor operation in various climates.
BMS Compatible: Ready for integration into modern building automation systems.
Commercial Buildings:
Medium-sized Offices: Providing zoned comfort cooling and heating.
Retail Stores & Shopping Malls: Serving individual stores or sections of a larger mall.
Restaurants & Hotels: For kitchen cooling, guest room comfort, and back-of-house areas.
Schools & Universities: Cooling classrooms, libraries, or administrative offices.
Healthcare Facilities:
Clinics & Small Hospitals: Providing critical temperature control for patient rooms, waiting areas, and laboratories.
Industrial Processes:
Machine Cooling: Stabilizing the temperature of production equipment, laser cutters, or plastic molding machines.
Server Rooms & Data Closets: Providing precise temperature and humidity control for IT infrastructure.
4. Other Applications:
Apartment Buildings: As a centralized system for common areas or for individual residential units.
Gyms and Fitness Centers.
