Description

Drainage system and air conditioner Technical Field The application relates to the field of air conditioners, in particular to a drainage system and an air conditioner. Background Stainless steel air-cooler uses extensively in food processing shop, medicine freezer etc. scene, but its comdenstion water system generally adopts straight tube formula drainage structures. This structure has a remarkable disadvantage in long-term operation that scale and bacterial film are formed due to the accumulation of impurities, minerals and microorganisms in condensed water on the pipe wall, resulting in a decrease in drainage efficiency. In addition, the traditional drainage system lacks effective antifouling function, easily causes problems such as pipeline blockage, bacterial breeding and the like, and seriously influences the operation efficiency and the sanitation and safety of the air cooler. Especially in the scenes of strict environmental requirements such as food processing, medicine refrigeration houses and the like, the defects of the traditional drainage system can cause product quality problems and potential safety hazards.
