|---|---|---|---|
| #rentingcoolingtips# | 12.8 | Installation-free equipment exhaust | |
| Douyin | "Air conditioning fan review" | 9.5 | Mobile cooling solution |
| little red book | “How to cool down without turning on the air conditioner” | 6.3 | Natural ventilation tips |
2. Installation-free exhaust core solution
1. Comparison of mechanical ventilation solutions
| Device type | price range | Applicable area | Energy consumption (W/h) |
|---|---|---|---|
| Circulation fan | 150-500 yuan | 10-20㎡ | 30-80 |
| Industrial exhaust fan | 200-800 yuan | 20-50㎡ | 100-200 |
| Window ventilator | 80-300 yuan | 5-15㎡ | 20-50 |
2. Natural ventilation techniques
•Cross ventilation method: Open windows at opposite positions at the same time to form air convection, which can lower the room temperature by 3-5°C according to actual measurements.
•Nighttime cold storage method: Turn on the ventilation throughout the house from 3 to 5 a.m., and close the curtains during the day to keep the room cool for 6 to 8 hours.
•Wet pad cooling: Hang a wet towel at the air inlet. Evaporation and heat absorption can reduce the inlet air temperature by 2-3°C.
3. Actual measurement data of popular products
| Product name | Wind power (m³/min) | Noise(dB) | cooling effect |
|---|---|---|---|
| Midea circulation fan GS2-8 | 18 | 35 | Body temperature drops by 3°C |
| Airmate window ventilator | 12 | 40 | Air exchange rate 85% |
| Delma Industrial Fan | 25 | 55 | 5 meters air supply |
4. Expert advice and precautions
1.Safety first: When using high-power equipment, check the circuit load to avoid using multiple high-power-consuming equipment at the same time.
2.Humidity control: Southern regions need to be used with a dehumidifier to prevent excessive humidity from affecting comfort.
3.Cleaning and maintenance: It is recommended to clean the filter of fan equipment every week to avoid dust accumulation that affects efficiency.
5. Sharing of user practice cases
• Shanghai renters @小A:"Window ventilator + ice box"Combined, it can cool down a 12㎡ bedroom to 28℃ when used at night.
• Beijing Baoma@miduo:"North and south window convection + circulation fan"Solution, the temperature in the living room is stabilized below 30°C in power saving mode
From the above structured data analysis, it can be seen that the exhaust solution that does not require the installation of air conditioners includes not only economical and practical equipment selection, but also involves the scientific application of air flow principles. Consumers can choose the most suitable cooling and exhaust solution based on their living environment and budget.
