Cold fan is a kind of household appliances used in summer. Its basic function is to absorb the heat in the air through water evaporation, thereby reducing the air temperature and achieved cooling effect.The working principle of the cold fan is to use the circulating water pump to pull out the water in the water tank. The waterfish system is evenly sprayed on the evaporate filter layer. The outdoor hot air enters the evaporation and cooling medium, and the heat is exchanged with the water to reduce the air temperature and blow out the out of the water.Cool, clean air.
Cold fan operation method
Instructions for operation description of the control panel of non -adjustable functional model:
Water level control function (assumption: point D is high water level, point A is the medium water level, point B is low water level, point C is a lack of water))
1. When the water level is at point C, the water deficiency is displayed, and the water inlet valve is automatically opened. It is not until the water level rises to point A, and the water level is extinguished. The water level reaches D to stop the water.If the water level is between point C and D, the pump can start displaying the low water level without displaying the lack of failure. The water inlet valve is automatically opened. When the water level reaches point D, the water is stopped.
2. During the operation, when the water level is at point C, the water shortage indicator is long, and the pump does not work. When the water level rises to point A, the pump starts to work, and the water deficiency indicator is extinguished.The water inlet valve stops working. When the water level drops to point B, the water inlet valve is opened, and automatic hydration to point D stops.
Note: If the liquid level sensor is not connected, all the functions of the control panel cannot be started, the power symbols, the hydrophilic symbols are bright, the fan symbols, refrigeration symbols, cleaning symbols and windfish flashes at the same time, and the peak device alarm.
Water inlet valve protection function: Under any working state, after 15 minutes of water inlet valve is opened, if the water level does not change, the water inlet valve will stop the water. After 15 minutes, open the water.:minute):
Host protection function: In the air supply or refrigeration state, if the control line between the control panel and the motherboard is disconnected, the host will stop after 10 seconds of running and turn to standby; if it is connected within 10 seconds, continue to run.
Failure alarm function: In the condition of refrigeration or air supply, the fault indicator light flashes to indicate the underwriting, the fault indicator light flash and the peak alarm indicate the flow, and all equipment will stop working.
Scope of application of cold fans
1. Places dense or short -term use time and need to cool quickly,
Such as: the auditorium, conference room, church, school, cafeteria, gymnasium, exhibition hall, shoe manufacturer, clothing factory, toy factory, vegetable market, etc.
2. Places with strong smell and large dust of pollution gas,
Such as: hospital lobby, waiting room, kitchen and chemical plant, plastic factory, electronics factory, chemical fiber factory, leather factory, spraying silk printing factory, rubber plant, print and dyeing plant, textile plant, breeding plant, etc.
3. There are production places with heat equipment or high temperature
Such as: mechanical processing, injection molding, electroplating, metallurgy, printing, food processing, glass, home appliances and other production workshops:
4. Shopping malls, supermarkets, playgrounds, casino, and waiting rooms that need to be open; suitable for agricultural scientific research and cultivation centers or bases.
