With the arrival of summer, air conditioning has become an indispensable household appliance in many people's lives. However, after long-term use of the air conditioner, a large amount of dust and bacteria will accumulate on the air conditioner evaporator, which will not only affect the cooling effect of the air conditioner, but also pose a threat to human health. Therefore, it is necessary to clean the air conditioner evaporator regularly.
The structure of the air conditioner evaporator mainly includes the following parts:
Liquid Refrigerant Inlet and Outlet: These are the two main interfaces of the evaporator that connect the refrigerant piping to enable the refrigerant to enter and exit the evaporator.
Evaporator coil: This is the core part of the evaporator, which consists of one or several groups of parallel metal coils. The refrigerant flows inside the coil, which absorbs heat and changes the refrigerant from a liquid state to a gaseous state.
Ribs: Ribs are metal sheets attached to the evaporator coil to increase the heat exchange area and improve the heat exchange efficiency of the evaporator.
Fan: The fan is an accessory component of the evaporator, which allows air to pass through the surface of the evaporator, taking the heat away from the surface of the coil, making it easier for the refrigerant to evaporate.
The cleaning of the air conditioner evaporator mainly includes the following steps:
Turn on the air conditioner for 15 minutes before cleaning the air conditioner so that the air conditioner can start to cool down and at the same time make the air conditioner evaporator produce condensation. Turn off the air conditioner after 15 minutes and cut off the power to ensure safety.
Open the case of the air conditioner, remove the dust filter, and clean it with tap water.
Clean the evaporator, if there is heavy dust on the evaporator fins, you can use a fine soft brush to remove it first. Then spray the air conditioner cleaner on the surface of the aluminum heat transfer sheet and coil on the evaporator fin to ensure that the cleaning foam completely covers the surface of the evaporator.
After waiting for about 15 minutes, the air conditioner cleaner will completely penetrate the reaction and fully disintegrate the stubborn dirt on the fins of the air conditioner evaporator, at which point you can wipe it clean with a soft cloth.
Reinstall the dust filter, cover the air conditioner shell, and gently wipe the air conditioner panel with a soft cloth dipped in warm water, not too hard to avoid damaging the coating on the panel.
Turn on the air-conditioner, turn the air-conditioning volume and cooling capacity to the maximum, and keep the air-conditioner on for 10 to 20 minutes to allow sewage to drain from the drain.
After the above steps are completed, the cleaning of the air conditioner evaporator is completed. Please note that it should be safe when cleaning to avoid dangerous situations such as electric shock. At the same time, cleaning agents and tools of qualified quality should be selected to avoid damage to the air conditioner and the human body. If you encounter difficulties in the cleaning process, it is advisable to seek the help of a professional.
The function of the air conditioner evaporator is to use the liquid low-temperature refrigerant to evaporate easily at low pressure, convert into vapor and absorb the heat of the cooled medium to achieve the purpose of refrigeration. It is a key component in an air conditioning system and is usually installed inside the indoor unit. When the fan of the indoor unit is running, the air flows through the evaporator, and the refrigerant on the evaporator absorbs the heat in the air, causing the air temperature to drop. In this way, the cooled air is blown back into the room, lowering the temperature in the room.
