Classify by Compressor Type
- Screw Chiller: It compresses the refrigerant gas through two intermeshing helical rotors. It features a compact structure, reliable operation, long service life, good partial load performance, and a wide capacity range. However, it has high processing accuracy requirements and slightly higher noise and vibration, which is suitable for medium and large-scale commercial and industrial projects and is one of the most widely used types.
- Scroll Chiller: It compresses gas by forming a constantly changing volume gas chamber through two intermeshing spiral scroll discs. It features a simple structure, extremely high reliability, relatively high efficiency, low noise and convenient maintenance. However, its single-unit capacity is relatively small, making it unsuitable for extremely large cooling demands, which is suitable for small and medium-sized office buildings, shops, restaurants, residences, etc.
Classified by the Cooling Method of Condenser
- Water Cooled Chiller: The condenser uses water as the cooling medium. You need to be equipped with a cooling tower and a cooling water pump. In a cooling tower, water comes into direct contact with air and the heat is dissipated into the atmosphere through evaporation. Its energy efficiency is about 20-30% higher than that of air-cooled types, and it operates more economically. However, you need to install a cooling tower and a water treatment system. Both the initial investment and the occupied area are relatively large, making it more suitable for medium and large-scale projects with installation conditions.
- Air Cooled Chiller: The condenser uses air as the cooling medium. Air cooled chillers usually come with fans that directly drive air to flow through the condenser coil for heat dissipation. It does not require cooling towers or cooling water pumps, is easy to install, and saves space and water resources. However, its energy efficiency is relatively low and it is greatly affected by environmental temperature, which is more suitable for water-scarce areas and small and medium-sized projects.
Reliable Certification
Our central chillers are ISO and CE certified, complying with global refrigeration standards for safe and efficient central cooling in large facilities.
- Successful Application Examples
Multi-building Complexes in the United Arab Emirates
A large complex in the United Arab Emirates includes offices, retail spaces, and public facilities. Multiple buildings require unified cooling. The project employs a 2,400-ton central chiller plant, consisting of four 600-ton units, which supplies chilled water to each building through the central chiller system. This centralized chiller solution avoids the need for each building to have its own cooling source, simplifying the overall cooling infrastructure. After the system was put into use, the cooling supply for each building was stable, and the operation and maintenance management was centralized and efficient.
Mexican Industrial Park
A certain industrial park in Mexico consists of multiple production workshops and assembly areas, with different cooling loads in each area. The project is equipped with a 1,800-ton central water chiller, consisting of three 600-ton units, and the chilled water distribution is optimized through the central chiller plant design. This central chiller solution concentrates the cold source for production and then distributes it through branch pipes to different production areas. The customer feedback is that the cooling supply for each workshop can be adjusted independently, and the overall cooling management of the park is clearer.
Upgrading of the Old Cooling Station in the British Commercial Area
The original central cooling station in a certain commercial area of the UK was old, and its control logic was outdated. The project was upgraded to a 3,000-ton centralized chiller system, using 3 1,000-ton units, and the pump groups and header pipes of the central chiller plant were redesigned. This central chiller solution enables unified scheduling of the units, pumps, and cooling towers. After the upgrade, the cooling station operates more flexibly, and the reliability of cooling supply in the commercial area has significantly improved.
Saudi Airport Terminal Building
In peak hours, various areas of a certain Saudi airport terminal building require a large amount of cooling capacity simultaneously. The project adopted a 4,500-ton central chiller system, consisting of three 1,500-ton central chillers, to serve the main cooling areas of the terminal building. The centralized configuration met the peak cooling load of multiple areas combined, avoiding the need to set up large cooling sources for each area separately. The client believed that this solution was suitable for the centralized cooling requirements of large public facilities.

What Is A Central Chiller?
ChillerOne central chiller is a cooling device that provides centralized refrigeration. It does not directly generate cold air but specifically produces low-temperature chilled water. Then, through water pumps and piping systems, this cold energy is delivered to various terminal devices distributed throughout the building, such as fan coil units. Ultimately, these terminal devices provide you with cold air.
Working Principles of the Central Chiller
- Evaporator: The liquid refrigerant evaporates in the tube bundle of the evaporator, absorbing the heat of the chilled water flowing outside the tubes, thereby cooling it down. Meanwhile, the refrigerant itself absorbs heat and turns into low-temperature and low-pressure vapor.
- Compressor: It sucks in the low-temperature and low-pressure refrigerant vapor from the evaporator and compresses it into high-temperature and high-pressure vapor. This process consumes the vast majority of electrical energy.
- Condenser: High-temperature and high-pressure refrigerant vapor enters the condenser, releasing heat to the cooling medium such as water or air flowing through it, and condenses itself into high-pressure liquid.
- Expansion valve: The high-pressure liquid refrigerant passes through the throttling device and suddenly drops in pressure to become a low-temperature and low-pressure gas-liquid mixture, and then re-enters the evaporator to start a new cycle.
