One premise is to buy high quality air cooler, quality can not be guaranteed, increase the service life is out of the question. The whole body of the air cooler, the blower and the fan blade materials must be qualified, and the overall design should be scientific, so as not to be easy to exhaust the air volume is small, the wind is low, the noise is loud and the use experience is not ideal caused by a variety of faults; Equipment installation of iron shelves, air supply pipes and special air outlets, air resistance of different materials should also be qualified, otherwise it will affect the service life of the equipment; The quality of the special electrical parts of the equipment must be cleared, otherwise it will affect the working quality and service life of the air cooler.

Second, the purchase of air cooler with strong technology content, some equipment with low technology content, can not identify the degree of dust blocking equipment, can not carry out automatic stain cleaning work, resulting in a certain degree of common faults, and then affect its service life. Then it is necessary to carry out regular human removal to avoid the blockage of anti-fouling filter or volatile hole. The air cooler is not checked regularly for cleaning, which will also lead to continuous deposition of stains on the basin body of the equipment, leading to common failures, which will not only affect the application, but also continue to reduce its service life. When the final stop in use, to the finned tube radiator in the frost layer, ice block water wash clean, the water in the water tray is discharged, and the axial flow fan will dry the water droplets. If the air cooler is not needed for a long time, all the refrigerant in the heat transfer pipe should be cleaned first, the gate valve in the air return valve should be opened, and the natural environment should be dry and manic to prevent the motor from returning moisture and paint falling off.
