1. The reason why the air conditioner is not cooling? Lack of fluorine: If your air conditioner is an old-fashioned air conditioner and has been used for a long time, it may be because the refrigerant in the air conditioner is gone, and you can continue to use it just by adding Freon. No cleaning: The outdoor unit of the air conditioner is exposed to the outdoors for a long time, and it is easy to absorb dust and debris. If it is not cleaned for a long time, it will affect the heat dissipation performance of the machine and the cooling effect of the air conditioner. If the filter of the indoor unit of the air conditioner is not cleaned for a long time, it will be clogged with dust, causing the air conditioner to fail to cool. Not enough horsepower: In other words, the number of horses of the air conditioner does not match the size of the room. Generally speaking, the cooling area of ​​1 HP air conditioner is 10-15 square meters, and the cooling area of ​​1.5 HP air conditioners is 14-22 square meters. Of course, you must choose a larger number of air conditioners to achieve the cooling effect. The temperature is too high: The summer is very hot, and high temperatures exceeding 42°C have even appeared in some areas. In this kind of weather, the cooling effect of the air conditioner is often not ideal. This is because when the outdoor unit is in an environment above 42°, it is difficult for most air conditioners to transfer the indoor heat to the outdoors, resulting in no cooling. 2. How much temperature is appropriate for the air conditioner? As we all know, the lowest temperature of general air conditioners is 16°C and the highest is 30°C. The minimum temperature of 16°C is to cool down quickly, not to keep you in an air-conditioned room at 16°C for a long time. Air conditioning is used in summer, and the temperature is set between 25°C and 27°C to feel better. It should be noted that the temperature difference between indoor and outdoor is not easy to be too large, and it is best to control it within 10°C. 3. Is the air conditioner better for cooling or dehumidification in summer? Let’s first think about a question: Why does the south feel hotter than the north because the temperature is also 37℃? Because the south is wetter than the north! The comfort of the human body depends on the environmental temperature on the one hand, and on the environmental humidity on the other hand. Studies have shown that the human body is most comfortable in an environment with a humidity of about 40%-60%. Since the humidity in the south is heavier than in the north, it will be more muggy. The cooling mode aims at lowering the temperature while removing water vapor in the air. It is suitable for environments with low air humidity, such as northern regions. Select the cooling mode, the cooling temperature and wind speed can be adjusted. The dehumidification mode aims to remove water vapor in the air while reducing the air temperature. It is suitable for environments with high air humidity, such as southern regions and rainy days. Select the dehumidification mode, the dehumidification temperature and wind speed cannot be adjusted up or down. 4. About air conditioning dripping This is because when the air conditioner is refrigerating, the air with higher indoor temperature and more water vapor enters the air conditioner condenser tube and then is cooled, and condensed water appears, forming water drops and dripping along the drain pipe. When heating, the outdoor unit will also produce a lot of water when defrosting. It is normal for the outdoor unit of the air conditioner to drip. 5. What's wrong with the water leakage of the indoor unit of the air conditioner? After talking about the outdoor unit dripping, let's look at the indoor unit leaking. The most common cause of water dripping in an indoor unit of an air conditioner is a drainage pipe problem. For example, there are hidden quality hazards in the drainage pipes, slack, aging, curved shapes, etc., will cause poor drainage, which will cause the indoor unit to drip. In addition, if the filters and fins of the indoor unit of the air conditioner are not cleaned for a long time, a large amount of dust will be accumulated, which will affect the cooling efficiency of the air conditioner, and will also cause the air conditioner indoor unit to leak. I will talk about how to clean it in the following question. Defects in the installation of the indoor unit of the air conditioner can also cause water leakage. For example, if the body is not level or the position of the drain pipe protruding outside is too high, the condensed water cannot be smoothly discharged outside and cause dripping. 6. Why does the air conditioner smell? After using for a period of time, the air conditioner often has a peculiar smell, but you can rest assured that it is not that the air conditioner is broken, but that the air conditioner has not been cleaned for a long time. The indoor unit evaporator that breeds a lot of bacteria has not been cleaned for a long time Due to the large aperture of the air conditioner filter, a lot of dust will adhere to the evaporator of the air conditioner indoor unit. The evaporator will produce condensation during cooling, condensing the moisture in the air on the surface of the evaporator, the humid environment and the dust attached to the surface of the evaporator, therefore, the air conditioner should be cleaned immediately after the odor appears. 7. How to clean the air conditioner? Clean the air conditioner filter In fact, the method is very simple, just spend 20 yuan to buy a bottle of air conditioner special cleaner and it is done! The main parts that need to be cleaned are the inside of the air conditioner filter, evaporator, and indoor unit housing. First, open the casing of the indoor unit, take off the filter of the indoor unit of the air conditioner directly, and wash it with water. Spray the air conditioner cleaner evenly on the surface of the evaporator and let it stand for 15 minutes Then clean the air conditioner evaporator with a special cleaner for the air conditioner. There are roughly two types of air conditioner cleaners. One is foamy, which needs to be spread evenly on the surface of the air conditioner's evaporator through the attached thin tube, and wait for the foam to melt by itself; the other is spray, which evaporates at a distance Spray evenly at 5 cm on the surface of the device and wait for 15 minutes. After cleaning, the evaporator is much cleaner After 15 minutes, directly install the air conditioner filter back to the indoor unit, close the indoor unit shell, and turn on the cooling mode to work for 15-30 minutes. The detergent and stains remaining on the evaporator surface will be discharged through the drain pipe along with the condensed water. outdoor. 8. Why is the air conditioner frequently started? First of all, only the fixed frequency air conditioner will start frequently. This is normal because it needs to maintain the temperature accurately at the set value. If the temperature difference between the set temperature and the room temperature is too small, it will aggravate the frequent startup of the fixed frequency air conditioner. In addition, if there are wind-blocking objects around the indoor and outdoor units of the air conditioner, it will also affect the heat dissipation and cause the air conditioner to start frequently. The inverter air conditioner will run at a low speed after reaching the set value to maintain the temperature unchanged, which can be said to be "non-stop operation". 9. Why did the air conditioner stop before reaching the set temperature? The working time of the air-conditioning compressor is limited. Normally, it should only stop when it drops to the specified temperature. However, if the outside temperature is too high or the set temperature in the city is too low, the compressor will take a break after working for a while, even if the temperature is still If the temperature is not lowered to the set temperature, this is the self-protection of the compressor itself—stop cooling. If your air-conditioning compressor has short working hours and long intervals, it's another matter. 10. Does frequent switching of the air conditioner cost electricity? Is it better to keep the air conditioner on or turn it off for a while? What kind of power saving? This issue is also of great concern to everyone. In fact, the power saving of the air conditioner mainly depends on the "startup rate". When the air conditioner is started, the compressor needs a lot of current, so it consumes more electricity. If the frequent switching on and off will cause unnecessary damage to the compressor, it is recommended that you Do not switch the machine frequently.
