Small private enterprises successfully developed scroll-type automotive air-conditioning compressors

A small private enterprise in Liuzhou, Guangxi Province, took the lead in researching and developing vortex-type automotive air-conditioner compressors with independent intellectual property rights, and obtained the appraisal conclusion that “the performance of major technical indicators has reached the international advanced level” in the performance testing of state-level professional organizations. .

This small private enterprise is Pudong Automotive Air Conditioning Co., Ltd. in Liuzhou High-tech Zone. It is a private enterprise specializing in the production of automotive air conditioners. The company's chairman and general manager Yu Huixiong introduced that the company developed a scroll-type automotive air-conditioning compressor, in key parts using aluminum alloy and self-lubricating wear-resistant materials and other new materials manufacturing, key technology patents have non-imitation characteristics, It will ensure that this product will lead at least 10 years of competitiveness.

Compressors are known as the "heart" of automotive air conditioning. Scroll compressors are favored by the market because of their comprehensive performance. According to reports, compared with piston compressors, which are still widely used today, scroll compressors have a simple structure with low cost, energy saving of 15% to 20%, high reliability in long-term operation, low vibration, low noise, and efficiency and cost-effectiveness. The market has obvious advantages. Scroll compressors will replace piston compressors.

However, two or three years ago, only the multinational companies in Japan and the United States were able to produce scroll compressors in the world, and the products were only supplied to Japan, America, Europe, and other places for high-end automobiles. Since the 1980s, many colleges and universities, research institutes, and large and medium-sized enterprises in China have started to develop this project, but most have failed.

In early 2003, Pudong Automotive Air Conditioning Co., Ltd. in Liuzhou High-tech Zone decided to develop a scroll-type automotive air-conditioning compressor. After nearly three years of hard work by the vast number of technical personnel, with the strong support of the Liuzhou Municipal Government and the science and technology department, they have invested more than 10 million yuan and have finally succeeded in the development. After being put into production, it can not only compete with similar products of Japan and the United States, but also this type of compressor can be widely used in other fields to improve the competitiveness of many products.

At present, Liuzhou High-tech Zone Pufa Automotive Air Conditioning Co., Ltd.'s scroll-type automotive air-conditioning compressors have undergone pilot-scale mass production, and a small number of products have entered the market. According to Qi Huixiong, the "Eleventh Five-Year Plan" started to strive for an output of 100,000 units.
