Core Viewpoint - The air conditioning market in India is poised for significant growth due to rising temperatures and increasing household income, with major Japanese manufacturers like Daikin planning to expand production capacity to meet this demand [1][2]. Group 1: Market Potential - India has recorded temperatures exceeding 50 degrees Celsius, making it one of the hottest regions globally, yet the air conditioning penetration rate is only about 7% [1][2]. - The air conditioning market in India is expected to grow from 7 million units in 2019 to 24 million units by 2029, indicating a substantial increase in demand [2]. - The International Monetary Fund (IMF) projects that India's nominal GDP will surpass Japan's by 2025, positioning India as the fourth-largest economy in the world [1]. Group 2: Competitive Landscape - Daikin currently holds the leading position in the Indian air conditioning market, with a 60% market share in commercial applications and 18% in the residential sector, closely competing with Tata Group's Voltas [2]. - Local manufacturers such as Voltas and Blue Star, along with South Korean LG Electronics, are intensifying competition in the Indian market [1]. Group 3: Technological Advantage - Daikin's competitive edge lies in its energy-saving technology, particularly its proprietary compressor systems that allow for precise control of energy consumption [3]. - The company has formed a joint venture with Taiwanese manufacturer Rechi to supply compressors to Indian air conditioning manufacturers, aiming to reduce costs through economies of scale [3]. Group 4: Service Expansion - Daikin anticipates growth in after-sales service demand, with the number of service outlets expected to increase from approximately 17,000 to over 20,000 by 2030 [3].
