Put some water in the air conditioning fan, and then use a wet mesh cloth to circulate it electrically. When the air blows, the water evaporates. When the water evaporates, it absorbs a lot of heat, and the air temperature drops. Although the temperature is It has dropped a bit, but the humidity of the air has increased. People are still uncomfortable, and the sweat they produce cannot evaporate. In addition, the air humidity is already high in summer, so its role is not great. It does not have a compressor and does not need to be used. Freon cannot achieve true refrigeration. However, this has not affected its popularity. The reason is that it is suitable for the climate characteristics of the north. The summer in the north is not unbearably hot but relatively dry. It does need humidification except for a few days in the rainy season. It is superior to electric fans in function, consumes much less energy than air conditioners, and costs only 500 to 700 yuan, making it more suitable for mass consumption.
The other is that the air-conditioning fan uses ice cubes to achieve a cooling effect. For example, Lianchuang's air-conditioning fan uses ice crystals to achieve a cooling effect. The freezing point of the ice crystals provided by Lianchuang is -12 degrees Celsius. The cooling effect is better than ordinary ice cubes and lasts longer.
The air-conditioning fans currently on the market are not high-tech products. It does not have a compressor or Freon, so it cannot achieve true refrigeration. However, this has not affected its popularity. The reason is that it is suitable for the climate characteristics of the north. The summer in the north is not unbearably hot but relatively dry. It does need humidification except for a few days in the rainy season. It is superior to electric fans in function, consumes much less energy than air conditioners, and costs only 500 to 700 yuan, making it more suitable for mass consumption.
Whether air conditioning fans on the market use water cooling or ice cooling, theoretically they all use the principle of direct evaporative cooling. In order to overcome its shortcomings, the use of indirect evaporative cooling has become an inevitable trend in its development, and it can also be combined with a dehumidifier to form a new household air conditioning system that uses heat for cooling. The core of indirect evaporative cooling technology is based on direct evaporative cooling, which uses lowered temperature water and air to cool the indoor air through heat exchange, taking away indoor heat without increasing the indoor temperature.
Second, it has wide applicability. Due to the application of dehumidifiers, it can be used in both the northern and humid areas during the rainy season.
Third, using water as the working medium, it is cheaper than current air conditioners, easy to maintain, and suitable for mass consumption.
Fourth, energy saving. This is in line with the current situation of China's energy shortage. Whether the cooling tower of the new air conditioning system uses spray cooling technology or ordinary cooling technology, and whether the dehumidifier uses compressor dehumidification or semiconductor dehumidification, its energy consumption is between 350-500W, which is about half of that of the air conditioner. Undoubtedly, its cooling capacity is slightly inferior to that of air conditioners, but it is suitable for the elderly and children and is not prone to air conditioning diseases. Therefore, this technology has attracted attention abroad and its application technology has also been developed. It is still under development and research in our country.
