What does snowflake mean in hotel central air conditioner?

Cooling mode.

The snowflake icon indicates the cooling mode, which is generally used in hot weather to lower the indoor temperature to a comfortable temperature. When the switch display shows snowflakes, it means that the air conditioner is currently cooling. The sun icon represents the heating mode, which is mainly used in cold winter. When the indoor temperature is very low, the heating mode can be used to warm the room. When the sun icon appears on the display, it means it is in heating mode. The fan icon represents air supply, and there are three modes: low wind, medium wind, and high wind. When turned on, air will be sucked in from the outside and blown indoors to provide ventilation. The water drop icon indicates the dehumidification mode of the air conditioner, which mainly reduces the temperature to bring the indoor air dew point to a critical value, so that excess water in the air can be analyzed to achieve the purpose of dehumidification. The triangle icon indicates automatic mode. The air conditioner will operate according to the mode set by the manufacturer. In this mode, the temperature of the air conditioner cannot be increased or decreased.

The temperature of the indoor air conditioner should not be too low in summer. The temperature in summer is relatively high. If the indoor temperature is too low, the temperature difference between the in and out will be too large after going out, making it easy to catch a cold. The air in indoor air-conditioned rooms is relatively dry, so you need to pay attention to moisturizing the air. You can use an air humidifier to adjust the indoor humidity, but the humidifier cannot be turned on all day long. It is not good if the air is too humid.
