150W Portable Evaporative Air Cooler Chiller, 45L Water Tank

Analysis of 150W Portable Evaporative Air Cooler Chiller (Model SBT-50) Noise Level and Silent Mode

1. Noise Level
a. Noise Levels at Different Wind Speeds
Low Wind Speed:
Noise Range: Usually 30-40 dB, equivalent to a whisper or quiet environment.
Applicable Scenarios: Suitable for nighttime use, bedrooms, or work environments that require a quiet environment. This gear provides relatively low air flow sound, and users can hardly hear the operation of the device.
Medium Wind Speed:
Noise Range: Usually 40-50 dB. This is equivalent to a whispered conversation in a library or normal indoor ambient sound.
Applicable Scenarios: Suitable for daily use, such as family living rooms, offices, etc. This gear provides good cooling while still maintaining relatively quiet operation.
High Wind Speed:
Noise Range: Usually 50-60 dB, similar to normal conversation or TV volume.
Applicable Scenarios: Suitable for rapid cooling needs, such as in extremely hot weather, or when the cooling effect needs to be quickly improved. Although this gear is noisier, it also provides greater cooling capacity.
b. Factors affecting noise
Fan design: The use of efficient, low-noise fan design can reduce the noise level when running at high wind speeds.
Material selection: The use of sound insulation materials and structural optimization design can effectively reduce the spread of vibration and noise.
Maintenance: Regular cleaning of fans and filters can prevent dust accumulation and keep the equipment running smoothly, thereby reducing operating noise.
2. Silent mode
a. Function of silent mode
Design purpose: Silent mode is designed to reduce the noise of the equipment during operation and is suitable for use in situations where a quiet environment is required, such as sleeping or working at night.
Working method:
In silent mode, the cooler automatically adjusts the fan speed and usually keeps it running at a low wind speed. This means that the equipment can keep the noise level to a minimum while providing sufficient cooling effect.
This mode may limit the cooling capacity of the equipment to maintain a quiet effect, but it can still meet general comfort needs.
b. Usage suggestions
Occasions of use: Silent mode is suitable for use at night, in the bedroom, study or other places where quietness is required. It provides users with a more comfortable environment and reduces the interference of devices on daily activities.
Comfort experience: When using silent mode, users can enjoy lower noise and suitable temperature, which helps improve sleep quality or concentration.
