Is Gree Air Conditioner Easily A Biochemical Weapon? Teach You How To Activate Two Anti-mold Logic Valves

Many families using Gree central air conditioners have encountered this situation. Just after blowing on the air conditioner for a few seconds, their throats began to feel tight and dry inexplicably. The room was also filled with a stale stuffy smell that could not be dispelled. They spent hundreds of dollars to find someone to deep clean it. Within two months, the strange smell reappeared. Many people did not realize that the root of the problem was hidden in the hidden link of the air conditioner's refrigeration operation.

The complete principle of mold and odor in air conditioners

The air conditioner running for refrigeration will definitely produce condensation water. After the whole machine is shut down directly, and when the ambient temperature around the aluminum evaporator (fin plate) covered with condensation water droplets rises rapidly due to the influence of room temperature, the moisture in the evaporator cavity and the daily adsorbed indoor dust are not discharged. When mixed together, it only takes 24 hours to form a dense biofilm. The strange smell you usually smell is actually volatile organic compounds generated by the metabolism of bacterial flora. Long-term inhalation of these low-concentration metabolites can cause persistent throat discomfort and nasal soreness in the morning.

Most of the self-cleaning functions promoted by most brands are through a simple process such as freezing and then melting water, which usually only lasts a few minutes and does not have a sufficient deep drying period. This is exactly in line with the user's usage habit of turning it off and away. Instead, it leaves enough space for mycelium to multiply.

Power-off drying operation process that can be used across brands

This general set of off-machine anti-mold and drying operations has no restrictions on the brand and model of air conditioners. For example, the Gree air conditioners used at home, or Meibo air conditioners, or air conditioners produced by Daikin, can all be followed directly.

First, manually adjust the operating mode of the air conditioner, switch it to the hidden auxiliary heat drying gear and run it at low speed, and use the drying temperature to completely evaporate the moisture remaining in the gaps between the evaporator fins; then, through the supporting brand's mobile phone smart APP, check the option to start the shutdown and drying function. Most mainstream brand air conditioners come with this supporting operation protocol when they leave the factory, but it is in an inactive hidden state by default. Many users are not aware that this function actually exists even after using it for five or six years.

Reference dimensions for selecting anti-mildew performance of household air conditioners

The anti-mildew performance of existing air conditioners can be selected or evaluated and self-inspected by comparing three clear reference dimensions: First, check the anti-mildew properties of the entire machine material, and check whether the components in the air conditioner that are in contact with water vapor have been treated with regular anti-corrosion and antibacterial coatings; second, pay attention to whether the drainage slope design of the core water receiving pan inside the air conditioner is appropriate, because a slope that is too small will cause residual residue after shutdown. The accumulated water remains at the bottom of the cavity for a long time and forms a bacterial bed; third, compare the CADR index marked on the filter with the actual filter pore size. A compliant filter can effectively intercept most dust particles floating in the room and cut off the source of nutrients required for bacterial growth. Therefore, there is no need to purchase a high-density filter with a smaller pore size, otherwise it will reduce the actual heat exchange efficiency of the whole machine and increase power consumption.

Low-cost mold inspection and do-it-yourself cleaning solutions

There is no need to ask a master to come to your home to confirm the internal mildew status of the air conditioner that has been running for a long time at home. You only need to turn off the main power of the air conditioner to prevent injury from touching the fan blades. Then find a household flashlight, aim it at the air guide blade of the air outlet, gently move the fixed blade outward, and observe the surface of the black cross-flow impeller on the inside.

If you see a large number of fine black spots evenly distributed on the surface of the wind wheel, which look like sprinkled with black pepper, it means that severe growth has occurred inside the air conditioner. When cleaning, do not use informal strong acid and alkali detergents, but use ordinary ones. The edible-grade hypochlorous acid flushing agent can be sprayed evenly into the inner cavity area of the fin gap and left for half an hour. The residual sewage will be discharged normally along the drain pipe on its own. The scale and mildew removal efficiency is more reliable than many paid door-to-door cleaning services that cost hundreds of yuan.

When using the air conditioner on a daily basis, you do not have to completely follow the so-called one-button smart shutdown mode recommended by the manufacturer. Before shutting down the air conditioner before going out, allow an extra 20 minutes of running time in a completely dry state, so that all residual moisture in the evaporator cavity can be completely drained.

This operation will basically not increase the daily electricity expenses. Just by slightly changing the usage habits when shutting down, you can avoid the trouble of continuous mildew and repeated respiratory discomfort in the air conditioner at home. It can also save hundreds of repeated expenses every year to disassemble and clean the air conditioner.
