Concept of Air Cooled Chiller
Water chiller is a kind of refrigeration equipment consisting of three parts: refrigeration system, waterway system and electrical system. The core is the refrigeration system. The refrigeration system is composed of compressor, evaporator, condenser and expansion valve. The air-cooled type water chiller is a water chiller whose condenser (radiator) is a fin type, radiating heat from the environment through one or more external rotor fans.
Features of Air Cooled Scroll Chiller
1. The Air Cooled Scroll Chiller is compact in structure, small in floor area, simple in pipeline design, requiring only external water pipes, and easy in installation and maintenance.
2. Intelligent control, the Air Cooled Scroll Chiller can automatically adjust the input compressor output according to the load change, so that the Air Cooled Scroll Chiller can maintain the best cooperation with the highest efficiency at any time.
3. Imported fully enclosed scroll refrigeration compressor is adopted. The utility model has the advantages of high efficiency, low noise, small vibration, reliable operation, long service life, etc.
4. Microcomputer control system is adopted by Air Cooled Scroll Chiller, with powerful functions such as safety protection, communication, fault judgment, automatic adaptation, etc; It can automatically monitor various parameters and operating conditions of the unit during operation.
5. The Air Cooled Scroll Chiller is integrated and modular. The modular unit is composed of 2~8 modules, featuring large cooling capacity, mutual standby and intermittent operation.
6. Air Cooled Scroll Chiller provides multiple protection functions, such as high and low voltage protection, antifreeze and icing protection of chilled water, power phase sequence protection, phase loss protection, insufficient water flow protection, compressor motor overheating, etc.
Advantages of Air Cooled Scroll Chillers
1. It is cost-effective. As it is an air-cooled vortex chiller, it does not need any water supply or pipe installation, and only uses the ambient air flow. Therefore, this is a fairly economical choice.
2. Less space occupation. Because the air-cooled vortex chiller is small, it occupies less space, which is very suitable for industries with small space for chillers. It can also be installed on the roof without a separate room.
3. Less maintenance. Compared with water-cooled vortex chiller, the other advantage of air-cooled vortex chiller is that it requires almost no maintenance. This is because it has fewer devices than the latter.
4. The design is simple and easy to operate. The air-cooled vortex chiller does not need any pump or condenser, so the system is very easy to understand and operate.
