中央空调维修保养原理：
Maintenance principle of central air conditioner:
清洗即通过物理或化学方法清除物体表面附着的污物，使其恢复原来表面的过程。
Cleaning is the process of removing the dirt on the surface of the object by physical or chemical methods to restore the original surface.
通过杀菌药剂清除循环水中的各种细菌和藻类。加入剥离剂、脱落生物粘泥；加入化学清洗剂、分散剂、将浮锈、垢、油污分散清洗排出，提供一个清洁的金属表面；投入预膜剂，在金属表面形成致密的聚合高分子保护膜，以起到防蚀作用；加入缓蚀剂，避免金属生锈；加入高分子阻垢剂，防止钙镁离子结晶沉淀。
Remove all kinds of bacteria and algae in circulating water by bactericide. Add stripping agent and abscission biological slime; add chemical cleaning agent and dispersant to disperse rust, scale and oil from the metal surface to provide a clean metal surface; add pre film agent to form a dense polymer protective film on the metal surface to prevent corrosion; add corrosion inhibitor to avoid metal rust; add polymer scale inhibitor to prevent calcium and magnesium ions from crystallization and sedimentation Dian.
