Product Overview – Natural Cooling Air-Cooled Screw Chiller

Poduct Detailed Description

The Aurashu Natural Cooling Air-Cooled Screw Chiller is an energy-efficient HVAC solution that combines free cooling and mechanical refrigeration in a single integrated unit. By utilizing ambient low outdoor temperatures during cooler seasons or in cold regions, the unit can meet partial or full cooling demand without engaging the compressor—dramatically reducing annual energy consumption and extending equipment life.

Equipped with high-efficiency screw compressors and intelligent control systems, the unit automatically switches between operating modes based on real-time environmental conditions, optimizing energy efficiency (EER/IPLV). It is particularly well-suited for applications that demand stable cooling and low operational cost, such as data centers, telecom rooms, industrial facilities, and large commercial buildings.

Compact in design, easy to install, and low in noise, this series supports modular expansion, remote monitoring, and flexible customization. It represents a high-performance, eco-friendly cooling solution aligned with the future of sustainable building systems.

Why Choose Our Modular Air-Cooled Chiller

Natural cooling air-cooled screw chiller

No Cooling Tower Required: Air source system reduces water use and infrastructure cost

1、Highly eficient heat exchange condenser, refrigerant sharing the same structure with ethylene glycol

2、Optional end glycol circulation to meet different needs

3、Can achieve safe refrigeration operation under temperatures of -40°C to 45°C

4、With intelligent program control, three refrigeration modes: compressor refrigeration, ethylene glycol

5、Refrigeration + compressor refrigeration, and athylene glycol reafrigeration can be automaticallyswitched to achieve high efficiency and energy conservation.

Wide Application Scenarios: Hotels, Hospitals, Theaters, Gymnasiums, Commercial buildings, Industrial and Mining enterprises, etc.

Frequently Asked Questions (FAQ)

Q1: How does the free cooling function work?

A:When outdoor temperatures are lower than the return water temperature, the system automatically switches to free cooling mode, using ambient air via an extra cooling coil or bypass loop.

Q2: Does this system work in hot climates?

A: Yes, in summer it operates as a standard air-cooled screw chiller. Free cooling activates only when ambient conditions permit.

Q3: What is the energy saving rate of free cooling?

A: Depending on your region and operation schedule, free cooling can reduce power consumption by up to 40–60% during winter or transitional seasons.
