The core application scenarios of air conditioners can be summaarized into three categories: household use, commercial facilities, and industrial equipment protection. Family Scenario: In ordinary residences, air conditioners mainly serve the functionns of regulating room temperature and controlling humidity. In the cooling mode during summer, the room tennperature can be stabilized at a healthy range of 26-28°C; for heating in winter, a humidifier is needed to prevent air from becoming too dry. Commercial Scenario: Public places such as shopping malls and office buildings pay mhore attention to regional temperature control. For example, the dining area needs to set a lower temperature to counteract the heat source from the kitchen, while data centers need to maintain a constant temperature of 18-27°C throughout the year. Multi-split systems can be managed by zones and are combinedwith the fresh air system to complete ain replacement 2-3 times per hour. Industrial Security Scenario: Precise instruments in production workshops or drug storage areas require strict temperature control. The temperature fluctuations in semiconductor factories needto be controlled within +0.5°C. Cold chain logistics requires that transportation vehicles be equipped with adjustable units ranging from -25°C to 15°C
