How about water cooled air conditioning fans?

The air conditioning fan is actually an electric fan equipped with water cooling device. It does not have a compressor, does not use Freon, rely on the built-in pump to let water circulate in the machine, and the surrounding air cooling. In this way, the fan blade to send the wind has a cold feeling, the temperature of the outlet is generally lower than room temperature by 3 5 C, the industry known as physical energy storage refrigeration. Air conditioning fan energy consumption is much smaller than air conditioning, the price is only about 500-700 yuan, and it is not easy to cause "air conditioning disease", so it is quite popular with some practical families. But some experts pointed out that the air-conditioning fan is not perfect, if used improperly, may bring some "health risks".

Air-conditioning fans refrigerate by water-cooling cycles, coupled with hot and humid summer air, cold air will inevitably cause condensation at outlets and other places, where bacteria are most likely to grow, and bacteria will be blown into the air with the cold wind. Therefore, for health reasons, the elderly and children with poor immunity should use air conditioning fans as little as possible.

Of course, if we take into account many factors such as price and energy conservation, air conditioning fans will still occupy a certain market space. As long as we pay attention to dehumidification and cleaning, we can use it to "healthy" summer.

1. Use pure water as far as possible when injecting water into the water cooling device. Pure water has high purity and less bacteria, which can reduce bacteria in the process of condensation. The water in the flume should be constantly added to keep it at a safe water level, and it should be replaced regularly.

2. After a long period of operation, the air conditioning fan will be blocked by dust and dirt, which will affect the air flow and refrigeration effect of the filter screen and curtain. Therefore, it is best to wash it once every two weeks.

Three, when using air conditioning fan, the distance should not be too close, should maintain air circulation and humidity balance. If necessary, consider using some dehumidifiers or dehumidification facilities.

Four, in addition, when purchasing air-conditioning fans, we should pay special attention to safety. When choosing cold air conditioning fans, check the sink repeatedly to ensure that the fan is free from leakage. Air conditioning fans that have just been purchased or have been shut down for a long time must be filled with clean water before use. The water level can be observed by a water mark to control the amount of water added. In addition, remember to pull off the power plug before adding water.

The principle of water cooled fan

Evaporative air-conditioner (water-cooled fan) is a modern high-tech product designed by scientists in Australia, the United States, Sweden and other places for many years. It adopts the highly efficient "direct evaporative" refrigeration technology, the principle is based on the water in the evaporation process to absorb heat, that is, under the condition of constant enthalpy, absorb the sensible heat of the air, so that the humidity of the air (dry bulb temperature) is reduced. The specific process is: when fresh air passes through the core component of evaporative air conditioner, Swedish high-tech patented product CELDEK staggered laminated wet curtain, the temperature on the wet curtain equals the air wet bulb temperature, the circulating water contacts the fresh air directly, generates heat exchange and filters out the dust in the air (the dust filtration efficiency reaches above 80%). The air is cooled by approximating an isoenthalpy change, and the air is eventually cooled to a wet-bulb temperature close to that of the air.

In the hot summer environment, the humidity of the dry/wet bulb of the air varies greatly, so the cooling effect is relatively high. Outdoor fresh air is filtered by evaporative air-conditioner and cooled, then it is continuously sent into the room, and the indoor turbid air with odor, dust and higher temperature is discharged out of the room, so that the indoor temperature is reduced and the oxygen content and quality of the air are relatively stable. Therefore, the evaporative air conditioner can achieve the dual effect of cooling and ventilation, and can create a fresh and comfortable living and working environment.
