From enclosure to seize share, half-sealed screw harvests markets above 40P In the industry, many people think that the semi-closed piston is like a stable big brother. Although it is very popular in the family, it still loses a little vitality. The scroll compressor is like the oldest one, grows up in love, is full of vitality, and dare to dare to do, but still have to work hard and steady. The semi-hermetic screw compressor has both strength and value, which is inevitable that some flowers of Gaoling are suspected. It turns out that these three types of compressors are all self-motivated, and Jingwei is more distinct. With the innovation of technology, the application fields have overlapped. It is understood that the mainstream position in the market is still a semi-hermetic piston compressor, which covers all stages of high, medium and low temperature. 3P-25P is mainly used in medium and high temperature, above 40P is mainly used in low temperature cold storage, the maximum power can reach 75P. When the semi-hermetic piston compressor operates at low temperature, multiple machines must be connected in parallel, while the screw compressor can be realized in a single machine, which can be realized in parallel. Therefore, it has high efficiency and easy maintenance in terms of operation. Compared with half-sealed pistons, the advantages of half-sealed screw compressors with large cooling capacity and stepless adjustment make them gradually penetrate into refrigeration, and the limitations of piston compressors in commercial refrigeration have affected the development of larger spaces.
Okmarts.com refrigeration experts pointed out, "Because the technical and after-sales personnel are familiar with piston compressors, they still occupy about 60% of the share, and the screw accounts for about 40%. From the customary use of pistons to the use of some screws, this is the current Chinese market. One of the transformation trends, I believe that as the market matures and the cultivation of enterprises, the screw compressor data will be more dazzling." However, screw compressor companies can not be satisfied with the market above 40P, many continue to attack below 40P, such as some small screws, and some companies combine the advantages of scroll and screw to create a single screw scroll double machine The compressor can achieve a minimum of 15P and a maximum of 40P, and its efficiency is at least 30% higher than that of a semi-closed piston. Whether these products can help screw compressors continue to seize more market share remains to be seen.
