Core Viewpoint - Europe is experiencing extreme heat waves, leading to increased demand for air conditioning, particularly from Chinese brands, as traditional attitudes towards air conditioning are shifting due to climate change and rising temperatures [2][10][16]. Group 1: Current Weather Conditions - Since June, multiple countries in Europe have recorded temperatures exceeding 40 degrees Celsius, causing disruptions in transportation and education, and resulting in heat-related fatalities [2][5]. - The European Centre for Medium-Range Weather Forecasts reported that June 2023 may become one of the hottest on record for Europe, with heat waves occurring more frequently and intensely due to climate change [3][4]. Group 2: Air Conditioning Market Dynamics - In the first five months of 2025, the European market for household air conditioning units saw a total of 12.773 million units sold, marking a 31.5% year-on-year increase, with Chinese brands leading the growth [2][17]. - The air conditioning penetration rate in Europe remains low, with only about 20% of households equipped with air conditioning, compared to nearly 90% in the U.S. and Japan [6][10].
