The cooling effect of air-conditioning fan is not so good. Air conditioning fan is actually an electric fan with water cooling device. It has no compressor, no freon, and relies on the built-in water pump to keep water circulating in the machine and cool the surrounding air. In this way, the wind sent by the blades has a cold feeling, and the temperature of the outlet is generally 3-5 degrees lower than the room temperature, which is called physical energy storage refrigeration by professionals. The power consumption of air-conditioning fans is much smaller than that of air conditioners, and the price is only about 500-700 yuan, and it is not easy to cause "air conditioning disease", so it is still popular in some practical families.
However, some experts pointed out that air-conditioning fans are not perfect, and if used improperly, they may bring some "health risks". The air conditioning fan is cooled by water cooling circulation. Coupled with the hot and humid air in summer, cold air will inevitably cause condensed water in places where bacteria are most likely to breed, such as air outlets, and bacteria will be blown into the air with cold air. Therefore, for health reasons, the elderly and children with poor immunity should use air-conditioning fans as little as possible. Of course, experts also stressed that if many factors such as price and energy saving are taken into account, air-conditioning fans will still occupy a certain market space.
One, when using, as long as you pay attention to dehumidification and cleaning, you can rely on it to "health" through the summer:
1. When filling water into the water cooling device, use pure water as much as possible. Pure water has high purity and few bacteria, which can reduce the growth of bacteria during condensation. The water in the sink should be added frequently, kept at a safe level, and replaced regularly.
2. After long-term operation, the air conditioning fan will be blocked by dust and dirt, which will affect the air volume and refrigeration effect of the filter screen and air curtain. So it's best to clean it once every two weeks.
3. When using air-conditioning fans, the distance should not be too close, and air circulation and humidity balance should be maintained. If necessary, consider using some dehumidifiers or dehumidifying facilities together. Fourth, in addition, when buying air-conditioning fans, we should pay special attention to safety issues. When buying an air-conditioning fan that needs cold water, check the sink repeatedly to ensure that the fan has no risk of electric leakage. Air-conditioning fans that have just been bought or stopped for a long time must be filled with clean water before use, and the water level can be observed through the water mark to control the water addition. In addition, remember to unplug the power plug before adding water.
Second, the principle of air conditioning fan
Air conditioning fan is a brand-new concept fan, which has many functions such as air supply, refrigeration, heating, air purification, humidification and so on. Taking water as the medium, it can send out wind equal to the water temperature in a short time, which is suitable for both cold and warm. Compared with electric fans, air-conditioning fans have the function of humidifying air, but their power is much higher than that of traditional fans, about 60-80W, but far lower than that of air conditioners. The water in the water tank is continuously pumped out by the circulating water pump and evenly sprayed on the evaporation filter layer through the water distribution system. Outdoor hot air enters the evaporative cooling medium and fully exchanges heat with water in the evaporative cooling medium CELdek (a honeycomb filter layer made of a special material, a Swedish high-tech patented product). The cool and clean air cooled by water evaporation is pressurized by a low-noise fan, so that the indoor hot air is discharged to the outside, thus achieving the purpose of indoor cooling.
