Rooftop Air-conditioning Unit (Split) Rooftop Split Air Conditioner Air-Conditioner

Product Description

Product Overview

Designed for large-scale cooling and heating needs, this unit integrates advanced compression-condensation and air-handling technologies to deliver reliable performance in commercial, industrial, and public environments. With refrigerating capacities ranging from 109 kW to 421 kW and heating capacities from 110.4 kW to 427.5 kW, it caters to diverse space requirements while ensuring energy efficiency and precise temperature regulation. Whether for office buildings, factories, or public facilities, this split rooftop unit combines space-saving design with powerful functionality.

Key Features & Benefits

Advanced Compressor Technology

Equipped with Hermetic Scroll Compressor (for mid-range models) or Semi-hermetic Screw Compressor (for high-capacity models), ensuring stable operation and low energy consumption.

Multiple compressor configurations (3 to 8 sets for scroll type; 1 set for screw type) adapt to varying load demands, optimizing efficiency.

Precision Temperature Control

Boasts a temperature control sensitivity of ±1℃, maintaining consistent indoor comfort even in fluctuating environments.

Flexible heating options (electric, steam, hot water) with heating capacities up to 280 kW, suitable for cold climates.

High-Efficiency Heat Exchange

Adopts Efficient Red Copper Tube Cover Aluminum Fin evaporators and condensers, maximizing heat transfer efficiency and reducing operational costs.

Optional refrigerants (R22/R410A) meet environmental standards and regional regulations, enhancing versatility.

Low Noise & Durable Design

Unit noise levels as low as 72 dB(A), minimizing disruption to indoor and surrounding environments.

Robust construction with heavy-duty materials (compression-condensation section weight up to 3000 kg) ensures long service life in harsh rooftop conditions.

Flexible Air Volume & Static Pressure

Air volume ranges from 8800 m³/h to 64500 m³/h, accommodating large open spaces and complex airflow requirements.

Adjustable external static pressure (400/600/800 Pa) supports customized ductwork designs.

Applications

Commercial Buildings

Office towers, shopping malls, hotels, and retail centers: Benefits from large air volume and precise temperature control to enhance customer and employee comfort.

Industrial Facilities

Factories, warehouses, and production plants: Handles high heat loads and maintains stable environments for equipment and operations.

Public Spaces

Schools, hospitals, exhibition halls, and transportation hubs: All Fresh Air Type variant ensures high air quality, critical for crowded areas.

Competitive Advantages

Versatile Model Range

Three core types and 16+ models cover small to large-scale applications, eliminating the need for custom solutions.

Energy-Saving Components

High-efficiency axial flow fans, centrifugal blowers, and optimized refrigerant circuits reduce energy consumption by up to 15% compared to conventional units.

Easy Installation & Maintenance

Split design allows separate installation of compression-condensation and air-handling sections; sectioned air-handling units simplify transportation and on-site assembly.

Reliable Performance

Operates under strict working conditions (refrigeration: 27℃/19℃ indoor dry/wet bulb; 35℃ condenser inlet) with consistent output.

Usage & Installation Guidelines

Installation Precautions

Mount the unit on a stable rooftop foundation capable of supporting the unit weight (700 kg to 3300 kg).

Ensure proper spacing for ventilation: Maintain at least 1.5 meters of clearance around the condenser.

Follow refrigerant pipe specifications (air pipe: 3×φ28 to 2×φ67; liquid pipe: 3×φ16 to 2×φ35) for optimal performance.

Operation Tips

Set temperature within 18℃ to 26℃ for cooling and 20℃ to 28℃ for heating to maximize efficiency.

Regularly check air filters (plate-type primary efficiency G3) and clean or replace every 3 to 6 months.

FAQ

Can I switch between heat pump and single cold modes?

Yes, the Heat Pump Type supports both cooling and heating, while the Single Cold Type is dedicated to cooling—choose based on your regional climate needs.

What refrigerant should I select?

R410A is recommended for environmental friendliness (low GWP), while R22 is a cost-effective option for existing systems.

Is the unit suitable for coastal areas?

Yes, the corrosion-resistant fin material and sealed compressors ensure durability in humid, salty environments.

How accurate is the temperature control?

The unit maintains a ±1℃ temperature precision, ideal for spaces requiring stable climates (e.g., laboratories, data centers).
