1. Report Industry Investment Rating The provided content does not include the report industry investment rating. 2. Core Views - The Chinese refrigeration and air - conditioning equipment industry is at a critical turning point. The domestic household market is in a stable development stage dominated by stock replacement demand, and growth is driven by the improvement of energy - efficiency standards. The report analyzes structural growth opportunities and long - term evolution trends by benchmarking overseas leading companies [2]. - Overseas expansion should focus on local in - depth development and value extension of the industrial chain. It is a systematic project, and mergers and acquisitions are strategic choices. Chinese enterprises are moving from the initial stage of "Made in China, Sold Globally" to the new stage of globalization of "brand, technology, and management" [2]. - The commercial refrigeration field, especially the data center refrigeration track, is a short - term growth highlight. The capital expenditure of overseas HVAC giants is directed towards data center infrastructure, and there is a market for high - end refrigeration solutions due to the need to improve energy efficiency and reduce PUE [2]. - Investment suggestions: In the household refrigeration equipment field, pay attention to industry leaders such as Midea Group; in the special - purpose refrigeration equipment field, focus on companies like Invic and Shenling Environment; for upstream components, pay attention to Hanzhong Precision Machinery, Binglun Environment, and Sanhua Intelligent Control [2]. 3. Summary by Relevant Catalog 3.1 Traditional Refrigeration Equipment Overview - **Global Refrigeration and Air - Conditioning Market**: The global refrigeration and air - conditioning market has shown steady growth. From 2018 to 2024, the global air - conditioner sales increased from 232.5 million units to 261.2 million units, with a compound annual growth rate of 2.0%. The proportion of household air - conditioners in 2024 was 73.7%, and the central air - conditioning market grew faster, with a compound annual growth rate of 4.0% from 2018 to 2024. It is predicted that by 2028, the global air - conditioner sales will reach 293.3 million units, with a compound annual growth rate of 2.9% from 2024 to 2028. Asia, North America, and Europe are important regional markets, and China is the largest single air - conditioning market [22]. - **Household Air - Conditioning**: In the 2024 cold year, China's household air - conditioner production accounted for 80.8% of the global total. Many domestic enterprises are increasing overseas layout. In the 2024 cold year, overseas production capacity increased by nearly 7 million units.
