Air-cooled chillers are one type of chiller, primarily consisting of three interconnected systems: the refrigerant circulation system, the water circulation system, and the electrical control system. The editor at Jucheng Chillers has summarized the following characteristics of air-cooled chiller units, hoping to provide useful information.
I. Efficiency Considerations for Air-Cooled Chillers
When choosing an air-cooled chiller, spending a little more for higher efficiency can truly offset annual energy costs, potentially saving up to half the purchase price of the chiller. While full-load efficiency varies between models depending on the available load, the difference is even greater in part-load performance as assessed by IPLV.
II. Characteristics of Air-Cooled Chillers
Air-cooled chiller units can be used in small systems, while most large units are water-cooled. Over long periods of operation, the cooling efficiency of water-cooled units tends to decrease, while air-cooled units maintain their efficiency. Using air cooling eliminates the need for cooling towers, cooling water pumps, and piping systems, avoiding condenser scaling and pipe blockage in areas with poor water quality, and also saving water resources.
III. Configuration Characteristics of Air-Cooled Chillers
- Compressor
Equipped with high-quality, high-efficiency copper tube condensers and evaporators, and world-renowned brand components, the unit boasts advantages such as small size, low noise, high energy efficiency, long lifespan, and easy operation. Its elegant and exquisite design and reliable, stable, high-efficiency quality stand out among similar products!
- Evaporator
The evaporator copper tubes use internally and externally threaded enhanced tubes. The copper tube surface has threads, the outer surface is smooth, and the cooling effect is good. The evaporator cylinder is insulated with 25mm thick PE insulation board, preventing condensation and minimizing heat loss.
- Condenser
The condenser uses copper tubes imported from abroad, processed into trapezoidal low-fin tubes to enhance heat transfer capacity. The smooth surface of the copper tubes reduces water pressure and facilitates cleaning and maintenance. 4. Protection Devices
The protection system includes: compressor delayed start protector, overload protector, high and low pressure protector, temperature control switch, anti-freeze switch, fuse plug, electronic time protection safety valve, compressor overheat protector, compressor frequent start protector, and abnormal indicator lights, ensuring the normal operation of the unit.
- Control System
The company has developed a highly intelligent PLC and PC-level computer control system, capable of remote monitoring and control, with multiple functions such as automatic loading and unloading, timed on/off switching, and fault cause recording; it is easy to operate, and the main unit is connected to the power supply. It has a low failure rate, high safety factor, simple installation, and the system control can be adjusted in real time, making it intuitive and reliable.
