High-Efficiency Low-Noise Axial Flow Fan
Inverted M-Type Finned Heat Exchanger
All Stainless Steel Bolts
Electronic Expansion Valve
Technical Parameter
High-Efficiency Low-Noise Axial Flow Fan
High-efficiency energy-saving motor, serrated low-noise blade design.
Inverted M-Type Finned Heat Exchanger
Hydrophilic aluminum foil with double-edge design, inverted M-type layout for uniform airflow.
All Stainless Steel Bolts
The large scroll compressor unit is installed outdoors, therefore, all the connecting fasteners for the machine's outer shell are made of stainless steel bolts, which offer better corrosion resistance.
Electronic Expansion Valve
The CAREL electronic expansion valve ensures precise throttling, contributing to system stability and high energy efficiency.
Unit Electrical Distribution Box
Outdoor electrical control box design.
Twin-Screw Compressor
Dedicated twin-screw compressor for heat pump applications, with the motor cooled by the refrigerant itself.
Heat Pump-Specific Compressor
Utilizes a semi-hermetic dual-screw compressor designed specifically for heat pumps. The gear design and compression ratio are optimized for optimal efficiency across diverse operating conditions.
Efficient Air-Side Heat Exchanger
Features an inverted M-structured design with new high-efficiency internal thread copper tubes that are tightly expanded with hydrophilic aluminum fins for superior heat exchange.
Electronic Expansion Valves
Equipped across the series, these valves use suction and release superheat bidirectional control technology, ideal for stable operation over a wide range of conditions, enhancing the efficiency of heat exchangers and ensuring safe, energy-efficient operation.
High-Efficiency Water-Side Heat Exchanger
Employs an effective shell-and-tube design. The asymmetrical tubing layout is tailored to refrigerant state changes, realizing high heat exchange efficiency.
Low-Noise, High-Efficiency Fans
The unit is fitted with axial fans that are low in noise and high in efficiency, directly driven by motors with an IP55 protection grade.
Advanced Control System
Features PLCs specialized for air conditioners and a high-definition true color touchscreen interface. This provides intelligent control and comprehensive protection, making the operation intuitive and easy to understand.
Modular Design
The unit boasts a modular design that allows for the combination of up to four modules, facilitating easy transportation, hoisting, and installation.
Application Scenarios
Widely utilized in hotels, hospitals, office buildings, shopping malls, factories, schools, and other scenarios requiring comfort and process air conditioning.
