The author understands that there are many types of compressors, such as reciprocating compressors, rotary compressors, centrifugal compressors, fully sealed piston compressors, rotor compressors, scroll compressors, etc.
With the increase in market demand and the development of technology, the size of the compressor market continues to expand. However, industry insiders said that from a subdivision perspective, the market performance of various types of compressors is very different.
For example, the full-sealed piston compressor, data show that from January to November 2018, the total production of piston compressors was 153.278 million units, an increase of 3.9% year-on-year; sales of 155.085 million units, an increase of 5.4%.
In addition, in December 2018, the overall sales of fully-sealed piston compressors increased slightly compared to the same period last year. The overall sales of fully sealed piston compressors in 2018 increased by about 5 percentage points year-on-year.
The performance of all-sealed piston compressor companies was also remarkable, and sales were better than the same period last year. Among them, there was a full-line growth in both domestic and overseas sales, with sales increasing by 76% year-on-year.
Another example is the rotor compressor. Experts said that the downstream orders in the first seven months of 2018 were in good condition and the production remained at the peak season. The overall situation was more optimistic. However, after July, due to the significant decline in the retail sales of air-conditioning terminals, affecting business confidence, the pace of production and shipment began to slow down.
It is reported that in 2018, the production and sales of rotor compressors achieved a small increase, with a production of 210.762 million units, an increase of 8.23% year-on-year; sales volume was 206.036 million units, an increase of 6.91% year-on-year.
In terms of corporate performance, in order to cope with the structural shortage of production capacity and the transformation and upgrading of products, compressor companies began to seize the trend of intelligence and increase investment in building intelligent production projects. In the face of new refrigerant, high-efficiency, frequency conversion technology development trends, as well as huge opportunities in emerging fields such as light business and heat pump heating, compressor companies are also increasing investment in research and development and launching innovative products.
However, there are also compressor market performances that are not optimistic, such as scroll compressors. It is understood that from January to November 2018, the cumulative output of the scroll compressor industry was 3,465,500 units, down 8.16% year-on-year; the cumulative sales volume was 3,463,900 units, down 7.98% year-on-year.
Experts analyzed that the market for scroll compressors was sluggish, with the domestic market falling by nearly 40%. Due to the weakening of downstream machine demand and the impact of dual-rotor models, mainstream vortex manufacturers all experienced different declines.
Although the performance of each compressor market is different, it also indirectly shows the current status of the compressor industry. For the status quo and future development of the compressor industry, the industry can be the most prominent problem is product innovation.
In this regard, compressor companies should upgrade their technology and products in response to market demand and market conditions. In addition, in order to maintain competitiveness and profit level, enterprises must further adjust the product structure, strengthen the breakthrough of technology level, and continuously improve the manufacturing system.
