When the Wind Speed Is Higher, It Will Be Cooler? The Truth May Be the Opposite.

When the Wind Speed Is Higher, It Will Be Cooler? The Truth May Be the Opposite.

Oct 14, 2025

I. Why is wind speed not equal to fast cooling? 

 

1. The core of refrigeration is the compressor. 

 

The cooling speed of the air conditioner mainly depends on the cooling capacity of the compressor, rather than on how fast the fan rotates. The wind speed increases. It just makes the airflow faster but does not directly increase the cooling capacity of the air conditioner. 

 

2. Wind speed only affects air circulation. 

 

When the wind speed is high, the cooling air will quickly mix in the indoor air, but the temperature drop is not necessarily significant. What you may feel is windy but not cool. 

 

II. Excessive wind speed may make you feel cold slowly. 

 

1. Hot and cold air mixed too fast. 

 

High wind speed will allow cold air and hot air to stir quickly, resulting in uniform but not concentrated cold sensation distribution, and the temperature difference felt by human skin is weakened. 

 

2. The initial temperature difference is not obvious. 

 

When the machine was just started, the evaporator had not completely cooled down. The high wind speed just blew out the wind with a higher temperature, and the somatosensory cooling rate was slow.

 

III. Hidden advantages of low wind speed. 

 

1. Cooling is more concentrated. 

 

Low or medium wind speed can make the cold wind send out in a fixed direction and quickly act on the area where the human body is located so that the body feels cooler faster. 

 

2. Energy-saving and quieter. 

 

The low wind speed reduces the energy consumption of the motor and also reduces the noise, which is especially suitable for use at night. 

 

 

IV. Suggestions on the use of wind speed in different stages. 

 

Usage Scenario Recommended Fan Speed Reason
Just turned on, high room temperature Medium speed or Auto mode Focus cool air on activity areas for faster perceived cooling
Room temperature near set value High speed Speed up air circulation to avoid hot and cold stratification
Sleeping at night Low speed or Sleep mode Reduce direct airflow, lower noise, and enhance comfort

 

V. Extra skills of scientific cooling. 

 

1. Reasonable temperature setting: refrigeration is set at about 26°C, taking into account comfort and energy saving. 

2. Close the doors and windows to prevent the loss of cooling air and reduce air conditioning load. 

3. Cooperate with the electric fan: low wind speed air conditioning + electric fan cycle can improve the somatosensory cooling efficiency. 

4. Regular cleaning of the filter: to ensure smooth air and improve refrigeration efficiency.

 

Raising the wind speed is not a universal 'accelerated cooling' method. In order to be both cool and comfortable, it is necessary to switch the wind speed reasonably at different stages. And with the scientific use of habits, so as to truly achieve efficient refrigeration and a comfortable life.
