The cooling circulating water pump of the air-conditioning fan equipment pumps the ice water in the water tank to the water separator. The water separator sends the ice water to the evaporator evenly. After the evaporator is drenched, an ice water film is formed on the surface; Tell the outdoor airflow sucked into the evaporator to quickly evaporate the ice water on the ice water film from the liquid state to the gaseous state, absorb the heat in the hot air, and send the cold air through the air guide at a high speed.
Popular version: It uses water as the medium and uses the latent heat of evaporation of water to cool. It relies on the pressure difference of the built-in water pump to make the water circulate in the water cooling device in the machine, so that the water and the air are fully contacted, and the water absorbs the heat in the air to make the air Cooling, and the cooling air is sent out by the fan motor, the human body will feel cold.
1. It is an electric fan equipped with a water cooling (ice) device
The single-phase shaded-pole asynchronous motor or single-phase permanent magnet synchronous motor drives the water curtain to move up and down slowly, and the single-phase capacitor running motor drives the fan to blow out the cold air with a certain humidity around the water curtain.
2. Because there is a certain humidity, it also has the effect of purifying the air
The other is to install a water pump in the air conditioning fan, where the water pump can cool the air in the water circulation and blow out cold air below room temperature. The air-conditioning fan does not have a compressor for refrigeration, and does not use Freon. The built-in water pump allows water to circulate in the machine continuously and cools the surrounding air. No matter which type of air-conditioning fan, the actual cooling effect is the same.
3. Electric circulation of wet mesh
When the air blows through, the water evaporates. At the same time as the water evaporates, a large amount of heat is absorbed. The air temperature drops, but the humidity of the air rises. The humidity of the air is high in summer, which may cause sweat to fail to evaporate.
4. Special fiber wet curtain paper evaporator
The evaporator is also a kind of partition type heat exchange equipment. The low-temperature and low-pressure liquid refrigerant vaporizes and absorbs heat on one side of the heat transfer wall, so that the medium on the other side of the heat transfer wall is cooled. The medium to be cooled is usually water or air.
5. Evaporator for cooling air
One type is the evaporative tube with natural convection of air, and the other type is the air cooler where the air is forced to flow. The air cooler used in the cold storage is made into a box type, and the air-conditioning fan is usually made of fins. In this kind of cooler, the refrigerant flows in the tube by the pressure difference, the gravity of the liquid or the pressure head generated by the liquid pump. Because the cooling medium air has a low heat release coefficient on the air side, the evaporator The heat transfer coefficient is also very low.
