如何选购家用空调（服务窗）

Core Insights - The article emphasizes the importance of selecting the right air conditioning unit based on consumer needs and preferences, especially during the hot summer months driven by the old-for-new policy [1][2]. Group 1: Product Selection - Air conditioners are categorized into fixed-speed and variable-speed types, with variable-speed units being more energy-efficient and quieter, making them a preferred choice for consumers [1]. - Air conditioners are also classified by installation type: wall-mounted units are suitable for smaller spaces like bedrooms, while floor-standing units are better for larger areas like living rooms [1]. - Consumers with only cooling needs can opt for single-cooling air conditioners, while those needing heating as well should consider heat pump models, although these may require supplementary heating in very low outdoor temperatures [1]. Group 2: Important Indicators - Key specifications to look for include "rated cooling capacity," "Annual Performance Factor (APF)" for heat pump models, and "Seasonal Energy Efficiency Ratio (SEER)" for single-cooling models [2]. - For a room of 10 square meters, a cooling capacity of around 2600 watts is recommended; for 15 square meters, about 3500 watts; and for rooms larger than 25 square meters, over 5000 watts [2]. - Higher APF or SEER values indicate better energy efficiency, and consumers are advised to choose air conditioners with an energy efficiency rating of level 2 or above [2]. Group 3: Meeting Individual Needs - Air conditioners with features like no-wind and anti-direct-blow functions are ideal for sensitive groups such as the elderly and children [2]. - Consumers focused on air quality and health should look for models with purification, fresh air, and self-cleaning functions [2]. - Young consumers seeking advanced technology may prefer smart air conditioners with remote control, voice interaction, and scene linkage capabilities [2]. Group 4: Certification and Standards - It is crucial to purchase air conditioners that carry the China Compulsory Certification (CCC) mark and the China Energy Label to ensure product quality and efficiency [3].
