After spraying air-conditioning cleaning agent, a large amount of foam will form on the surface of evaporator, and the foam will disappear naturally. In fact, there will be a lot of residue on the surface of air conditioner evaporator. In summer, it is necessary to open the refrigerator. There will be a lot of condensed water on the evaporator surface of the air conditioner, and the cleaning agent residue of the air conditioner will flow outdoors through the drain pipe with the condensed water.
Correct handling method:
1. After cleaning the heat exchanger of the air conditioner, the air conditioner is turned on for cooling operation for more than 4 hours, and then operated in air supply mode 1-2 hours;
2. Or after cleaning the air conditioner, use a kettle to spray water on the heat exchanger of the indoor unit of the air conditioner. Clean the remaining detergent, and then blow dry the water 1-2 hours when the air conditioner is running in air supply mode.
Extended data:
The refrigeration principle is divided into two parts.
1. Binary solution is heated and boiled by the heat source in the generator to generate refrigerant vapor, which is condensed into refrigerant liquid in the condenser. The liquid refrigerant enters the evaporator after being throttled by the U-tube, and evaporates and absorbs the heat of the refrigerant after being injected at low pressure, resulting in refrigeration effect.
2. The concentrated solution from the generator automatically flows into the absorption tower after being cooled and decompressed by the heat exchanger, and is mixed with the original solution of the absorption tower to form a concentrated solution with medium concentration. The concentrated solution is transported and sprayed by the absorption pump, and the refrigerant vapor discharged from the evaporator is absorbed into the dilute solution, which is pumped to the generator by the generator, and the refrigerant vapor is regenerated by the heat source to form the concentrated solution, which enters the next cycle.
Any refrigeration equipment has four main components (compressor, condenser, evaporator and throttling device), and the refrigerant absorbs or releases heat through the change of physical state in the refrigerator to achieve the effect of refrigeration or heating.
