Product Description

Passed inspection by the National Air-Conditioning Equipment Testing Center

I. Product Classification

1. Air-cooled screw chiller: single-refrigerant system, used for large-scale centralized cooling supply.

2. Air-cooled screw heat pump unit: dual-purpose for heating and cooling—provides heating in winter and cooling in summer.

3. Low-temperature model: operates reliably at -15°C to -25°C; suitable for use in northern regions during winter.

II. Core Specifications

Cooling capacity: 60 kW to 600 kW (single- or twin-screw compressors); heating capacity: 65 kW to 650 kW (heat-pump type); chilled water outlet temperature: 7°C; hot water outlet temperature: 45–55°C; power supply: 380 V / 50 Hz; refrigerants: R410A and R134a, environmentally friendly refrigerants.

III. Core Configuration

Compressor: semi-hermetic high-efficiency screw type, 5:6 asymmetric rotors, stepless capacity modulation from 10% to 100%.

Heat exchanger: high-efficiency copper-tube, aluminum-fin design with hydrophilic coating for corrosion resistance; large-airflow heat exchange.

Fan: Low-noise axial fan with variable-frequency speed control and intelligent noise reduction.

Control System: PLC touch screen, RS485/MODBUS, remote mobile app, multi-unit networked control

Protection: high and low voltage, overload, freeze protection, phase loss, oil pressure differential, and motor overheating.

IV. Performance Characteristics

High energy efficiency: EER ≥ 3.2, IPLV Level 1 energy efficiency, and greater energy savings under partial load.

Stable and reliable: the screw design is resistant to liquid hammering, features a low failure rate, and can operate continuously for 24 hours.

Smart Defrost: Automatically detects when defrosting is needed, preventing ice buildup at low temperatures and ensuring continuous operation.

Simple installation: no cooling water system required—just plug it in and it’s ready to go, with a short construction period.

Silent Operation: Low-Noise Fan + Vibration Damping, Noise Level 70–82 dB(A)

V. Applicable Scenarios

Shopping malls, hotels, office buildings, hospitals, and schools; factory workshops, data centers, and sports venues; water-scarce regions, machine-room-less installations, retrofitting of existing buildings, and heating in northern climates.

VI. Summary of Advantages

Compared with water cooling: no cooling towers, no water pumps, no dedicated equipment rooms, and faster installation; compared with air-cooled scroll systems: higher cooling capacity, greater stability, and longer service life; compared with air-source systems: the preferred choice for large-scale centralized cooling and heating.
