Snowflake: Refrigeration. According to inquiries on Qijia.com, we learned that air conditioner symbols include snowflakes, water droplets, wind blades, sun, etc. The snowflakes represent cooling, the water droplets represent dehumidification, the blades represent air supply, and the sun represents heating. The upper and lower triangles are used to adjust the temperature; the ventilation buttons include Ventilation 1 and Ventilation 2. These two ventilation standards are used for ventilation. The speeds are different; the timer switch is used to control the switching time of the air conditioner.
