Refrigeration compressor Ten years (Ⅱ)

Segmented products vary in performance

From the perspective of product segmentation, fully enclosed piston compressors occupy an absolute dominant position with a large volume, with a ten-year compound growth rate of 6.8%, and sales volume of 229.4 million units in 2022, accounting for 99.6% of the total refrigeration compressor industry. The fully sealed piston compressor is mainly used in household refrigerator freezers, and the domestic refrigerator freezer market is mature, and the demand is relatively stable, which determines the relatively stable trend of the fully sealed piston compressor market, at the same time, the fully sealed piston compressor products are also expanding to the light commercial refrigeration equipment, DC refrigeration equipment, dehumidifier and other fields.

Rotor compressors are mainly used in light commercial refrigeration equipment, and a small number of applications in small cold storage. In recent years, rotor compressors rely on energy saving and price advantages, and the proportion of applications in commercial refrigeration equipment is growing. In 2022, the total sales volume of rotor compressors was 340,000 units, with a ten-year compound growth rate of 29.3%, which is the highest compound growth rate among refrigeration compressor segments. With the expansion of frequency conversion products and large cooling capacity products, the scale of rotor compressors is expected to continue to grow in the future.

Scroll compressors are mainly used in small and medium-sized cold storage, and also have a small number of applications in refrigeration equipment such as remote refrigeration display cases and large ice makers. In 2022, the market size of scroll compressors will be 310,000 units, with a ten-year compound growth rate of 9.6%. In the past decade, scroll compressors have maintained a growth trend, only declining in 2022, mainly due to the reduction in the number of stores in commercial scenarios such as supermarkets, down 3.6% year-on-year. With the continuous increase of small and medium-sized cold storage applications such as production areas and communities, the demand potential is still strong. Semi-enclosed piston compressor is mainly used in cold storage,

Remote refrigerated display case. Semi-enclosed piston compressors sold 170,000 units in 2022, down 8.7% compared with the same period in 2021. Influenced by the double extrusion of scroll and screw compressors, the scale of semi-enclosed piston compressors continues to decline, with a ten-year compound growth rate of -2.0%. Semi-enclosed piston compressor line

The industry has a substantial growth of 15.6% in 2021, on the one hand, benefiting from the recovery of the industry after three years of continuous decline; On the other hand, the cold chain industry has developed in an all-round way, the number of refrigeration projects has increased significantly, the construction of cold storage, especially the construction of low temperature cold storage, and the demand for semi-enclosed piston compressors is increasing.

Screw compressors are mainly used in large cold storage projects, large ice makers, quick-freezing equipment and other large refrigeration equipment. In 2022, the sales volume of screw compressors was 30,000 units, an increase of 7.6%, and it was the only compressor category to grow in refrigeration compressors in 2022. Over the past decade, the scale of screw compressors has continued to expand, with a ten-year compound growth rate of 20.3%. With the reduction of the cost of screw compressors and the gradual maturity of technology, the market recognition of screw compressors has increased year by year, and the country has continued to increase investment in cold storage construction, especially the construction of medium and large cold storage projects, which has further stimulated the growth of demand for screw compressors.
