The Secret Behind The Principle Of Air-conditioning Cleaner: Spray It And All The Mold And Dust In The Evaporator Will Be Dissolved
A few days ago, I went to a friend's house to be a guest. As soon as I entered the door, I noticed that the air was a little dull and mixed with an indescribable sour smell.
A friend said that it was possible that the air conditioner had not been cleaned for a long time. He himself had tried wiping the outer casing and cleaning the filter, but the smell still remained.
This reminded me of the misunderstandings that many families have in daily cleaning. People often only pay attention to the layer of floating dust on the surface of the air conditioner. At most, they take out the filter and brush it, and then treat it as done.
In fact, the place inside the air conditioner that is most likely to harbor dirt and evil and is also the key to breeding bacteria is the evaporator.
The evaporator is the "root cause" of air conditioner diseases
Why evaporator So dirty?
The key is how it works.
During refrigeration in summer, the surface temperature of the evaporator is very low. When the water vapor in the air is cooled, it will condense into water droplets, which is condensation water.
This water will adsorb dust and lint in the air, thus forming an environment that is humid and rich in "nutrients", which is simply a breeding ground for mold and bacteria.
After a period of time, a layer of mold in the shape of white hair will grow on the evaporator.
When the air conditioner is turned on again, these dirty things will be blown into the indoor air.
When people stay in such an environment for a long time, they are prone to symptoms such as dizziness, nasal congestion, and coughing, which are called "air conditioning disease."
Therefore, just by washing the filter, it only solves the superficial problem, but it cannot cut off the root cause. Only thorough cleaning of the evaporator is the core point.
Preparation before cleaning
After finding the "root cause", cleaning will be targeted.
First you need to prepare a bottle Special cleaning agent for air conditioners .
This thing can be bought in supermarkets or online, and it is not expensive, with an average price of about 20 yuan.
My friend bought two bottles from the supermarket for spare use at 15.9 yuan each.
If you don't need it extremely urgently, you can compare several different brands on the Internet and choose the one with better reviews.
After preparing the cleaning agent in advance, be sure to remember that the first step is to cut off the power of the air conditioner to ensure the safety of the operation.
Then find the filter buckle on the back of the fuselage, and then slowly and briskly but cautiously pull out the two filters.
Filter cleaning and precautions
The moment I pulled out the filter, my friend and I were shocked.
This air conditioner has been used for five or six years. The dust on the filter is so thick that it is even somewhat caked.
Even if the hygiene conditions at home are very good, the filter, which is called the "air guard", does withstand a large number of things.
Bring the filter to the pool, rinse it with clean water, and then wipe it gently with a rag or soft brush. In this way, cleaning the filter will be very simple.
There is a little trick here. If you use a brush, the force must be light to prevent the mesh of the filter from being enlarged, otherwise the filtering effect will be affected.
After cleaning, be sure to dry it completely before reinstalling it. A wet filter can easily breed bacteria.
In addition, some of the current high-end appliances called air conditioners are equipped with HEPA filters and activated carbon filters.
Please note that HEPA filters generally cannot be washed. When there is not much dust, you can use a vacuum cleaner to clean its surface. Activated carbon filters are mostly used to absorb odors and can be regularly placed under the sun to evaporate the adsorbed formaldehyde and other substances, thereby restoring some functions.
Core Step: Deep Cleaning of Evaporator
The filter is just an appetizer, and the real highlight is cleaning the evaporator. This is a fact.
After removing the air guide plate with a screwdriver, the cylindrical evaporator inside is exposed.
The surface of this machine at a friend's house has been covered with a layer of obvious white mold, which is the direct source of odor and health risks.
Then, connect the nozzle of the air conditioner cleaning agent properly and spray it on the fin surface of the evaporator in an even manner.
The design of this cylindrical cabinet air conditioner in a friend's home has to be solved here. The air outlet is narrow, and the angle must be continuously changed during the spraying operation. Compared with the traditional cabinet air conditioner, it is much more troublesome.
When spraying, try to cover the entire area and allow the cleaning agent to fully soak into the stain.
The principle and “self-cleaning” function of cleaning agents
After spraying, you need to let it sit for about 15 minutes.
This waiting process is of considerable importance. Its goal is to promote the cleaning agent to fully react with dirt such as dust, mold, and oil stains and achieve dissolution.
It's involved here The principle of air conditioning cleaner .
It mainly contains ingredients such as surfactants, bactericides and solvents.
Surfactants are responsible for reducing the adhesion of dirt, solvents are capable of dissolving oily stains, and fungicides are responsible for killing microorganisms.
After the rest is completed, turn on the power of the air conditioner for power supply operation, set the operating mode of the air conditioner, set it to cooling mode, adjust the temperature to the minimum (usually the minimum temperature is 16°C), and adjust the wind speed to the maximum state.
The operation lasts for 20 to 30 minutes. During this period, the evaporator once again produces a huge amount of condensation water. This condensation water will wash away the dirt dissolved and stripped by the cleaning agent and be discharged to the outside through the drain pipe of the air conditioner.
If you see it here, you may understand: the core principle of the self-cleaning function promoted by many air conditioners is to first form frost on the evaporator, and then use the flushing of condensed water to take away the dirt.
If the stains on the evaporator are hardened and there is no cleaning agent to dissolve them in advance, and only condensed water is used to wash them, the effect will be greatly reduced.
Cleaning is complete and the results are immediate
After enduring about an hour of fussing, I turned on the air conditioner again, and the air blown out became noticeably fresher and cooler, and the sour smell before was completely gone.
Looks clean again evaporator , full of sense of achievement.
Calculate based on economic considerations: If you ask someone who specializes in after-sales or housekeeping work to come to your home for cleaning, the service fee you need to pay will generally not be less than 100 yuan.
Buy your own cleaning agent. One bottle can clean a machine twice, and the cost per time is less than 10 yuan.
In addition, regular cleaning of the inside of the air conditioner can not only ensure that the respiratory tract is in a healthy state, reduce the chance of suffering from "air conditioning disease", but also improve the heat exchange efficiency of the air conditioner, thereby saving electricity, reducing noise, and extending the service life of the air conditioner.
Cleaning the air conditioner yourself is not as complicated as you think.
The most important point is to understand the reasons why the evaporator becomes dirty and the principles behind air conditioning cleaners, and then prepare the relevant tools and follow the steps.
During the season when the air conditioner is used frequently, it is recommended to clean the filter every one to two months and perform a deep cleaning of the evaporator every six months to one year.
Developing such a habit can protect the health of family members and save money. Why not do it happily?
