Features of screw and centrifugal chillers

The chiller is a kind of water-cooled equipment as its name implies, but it is a mechanized equipment that can provide constant temperature, constant pressure and constant current. It is not only simple to operate, but also energy-saving and environmentally friendly because of the recycling of water. The effect of applying it to industry is very big. Without much gossip, let us take a look at the characteristics of these two chillers.

　　 One, screw type

　　Advantages: This type of chiller has simple body components and relatively few moving parts, which means less loss. At the same time, it is not sensitive to wet stroke, so the side shows that its service life will be very long. In addition, because of the operating principle, the noise is small. It also has the advantages of simple and easy operation, strong power saving ability, small size and light weight.

　　Insufficient: high price, low single-machine capacity, low speed, high fuel consumption, and high technological requirements.

　　 Two, centrifugal

　　Advantages: The centrifugal chiller has compact structure, the parts are not easy to wear, the speed is quite stable and high, the noise is low, the air volume is large, the performance of the main components for refrigeration is super good, and the eer value is also quite high. It's really an advantage that can be said.

　　Insufficient: The program is too rigid, and it is prone to surging at low load, which is like the feeling of a washing machine throwing a bucket, and it is also extremely vulnerable to chemical corrosion.

　　 The above is a simple comparison between the screw and centrifugal chillers. The advantages of both are very obvious. But the disadvantages are also different, after all, the focus of each machine is different. The choice of these two types of chillers mainly depends on the factory itself, so when buying, you must make a reasonable choice according to your own needs, so as to ensure the performance.
