What is the reason why the air conditioner does not cool?

Although the hot summer has passed, this article is still going to introduce you to the reasons why the air conditioner does not cool. Air conditioner is also called air conditioner. Air conditioner is the equipment that handles the temperature, humidity, purity and airflow speed of air to meet people's production and living needs. It is referred to as “air conditioner” for short.

As one of the popular home appliances in modern homes, many users seem to be very familiar with the brands, models and uses of various air-conditioning products on the market. However, once the air conditioner fails, it seems a bit overwhelmed. One of the more common faults, there are many reasons why the air conditioner does not cool, how to do the air conditioner does not cool, take a look at the following solutions.

One of the reasons why the air conditioner does not cool: the air conditioner has reached the service life, the normal service life has passed, and the air conditioner is aging.

I used to buy a second-hand air conditioner in my hometown. I suddenly stopped cooling. I went through a lot of books and found a lot of information on the Internet in order to find the reason why I didn’t cool the air conditioner. Although I was enriching myself about air conditioning. Some knowledge of refrigeration, but I can't fix the old air conditioner in my home. The reason is that the large-scale household appliances such as air conditioners generally have a service life of 15 to 20 years. This year, even if it is repaired, there will be such problems. . Solution: Change it.

The reason why the air conditioner does not cool is that the refrigerant is not enough, that is, the Freon is not enough, and the snow is not enough.

The reason why air conditioning is cooled is because of Freon. When the air conditioner motor starts, it will open the function of Freon. The general reason for Freon is not enough. It is also the normal situation that the air conditioner has been used for three years, if you find the air conditioner in your home. The cooling effect is not as good as it used to be. This is the reason. Solution: When the air conditioner is purchased, it will be accompanied by Freon. You can add it yourself. If it is not the best to find a repair master to help you. One thing to remind you here is not to over-use Freon, which will be counterproductive.

The reason why the air conditioner does not cool is the third: the copper tube between the outdoor unit and the indoor unit is too long.

Some friends feel that the outdoor unit is too noisy, and they intentionally move the outdoor unit far away, which increases the distance of transmission, resulting in a decrease in the cooling effect of the air conditioner. In addition, the cost of installation is increased, which is not cost-effective. The air conditioner is caused by the demand of the device or the device is unreasonable, so that the air duct is too long, so that the heat transfer efficiency is low, and the air conditioner is not cooled. Solution: Minimize the length of the copper tube between the outdoor unit and the indoor unit

The reason why the air conditioner does not cool is that the air conditioner does not clean and maintain for a long time, resulting in no refrigeration.

When I bought the air conditioner, everyone thought that I could enjoy everything. In fact, we have to stop the maintenance of air conditioners in many ways. One of them is that Daikin central air conditioner is easy to neglect it because the outdoor unit is installed outdoors. The long-term use of the outdoor unit will cause a lot of dust, dirt and other dirt to be absorbed on the radiator. The effect is poor and the innocence is not cooled. In addition, the long-term indifference about air-conditioning maintenance will make the air in the room unsanitary, more susceptible to air-conditioning diseases, increase in power consumption, and shorten the service life of air conditioners. Solution: Clean and maintain the air conditioner, so that the clean outdoor unit can dissipate heat more late.

The reason why the air conditioner does not cool is five: the household voltage is not enough, the supply voltage is not normal, and the time is high and low.

In some large factories or companies, central air conditioning and refrigeration are generally used, and then the ventilation fans are used to achieve cooling in different areas. Here, there will be problems. When the voltage is insufficient, the air conditioner will suddenly stop and not cool at all; or the air conditioning will be cold. Cold and hot. Many friends can't find the reason for this non-refrigeration. The maintenance technician also removed the air conditioner and installed it again or not. This situation should be considered due to voltage instability. Solution: Ensure that the voltage in the home is stable, especially during peak hours. Buy a higher resistance and voltmeter to monitor the voltage at all times.

The reason why the air conditioner does not cool is six: the power of the air conditioner is not enough to be cooled.

Some friends in order to save money to buy a small number of air conditioners in a very large room, the original small number of air conditioning power is not enough, although the air conditioning power and room area seems to match, but because the room is relative Not sealed, or there is a heat source in the room (many computers) Of course, the glass room is also one of the heat sources, and so on. This kind of situation is easy to ignore in our usual situation. If we find this reason and deal with it well, it can not only make the air conditioner cooler, but also save electricity and extend the service life of the air conditioner. Solution: Estimate the practical area when purchasing air conditioners. If the funds are sufficient, you can add 0.5-1 horses based on the appropriate number of horses.

The reason why the air conditioner does not cool is: the external environment temperature is too high, so the air conditioner does not cool.

In some areas where high temperatures are common throughout the year, because the outdoor temperature is too high and exceeds the air conditioning refrigeration limit, air conditioning may not be cooled. This uncooled condition is common in our outdoor units being installed in a space that is more than blocked or overheated around the outside. In order to have a beautiful appearance, the outdoor unit is installed in a small enclosed space so that a plurality of outdoor units are placed in a small space, so that it is extremely easy because the small space in which the outdoor unit is located does not circulate, causing the radiator to disperse. The heat that comes out is not flowing away, so that there is no wind and no refrigeration. There is a common saying that when the outdoor temperature exceeds 43 degrees, most air conditioners are difficult to transfer indoor heat to the outdoor through the radiator of the outdoor unit. Will form an air conditioner without cooling. Solution: Change the environment of the outdoor unit and install it in a well-ventilated place.

As the temperature changes, the cold winter is coming. After the "Autumn Tiger", many families' air conditioners entered a "rest" state. However, the air conditioner will not be energized because of rest for a period of time. On the contrary, Xiaobian learned from the air-conditioning maintenance department that it is because the air conditioner is not used for a long time, which causes it to strike. It can be seen that before the winter season, we maintain the air conditioner. And maintenance is indispensable. Let's introduce Xiaobian to some basic maintenance methods for air conditioners:

1, the temperature can be set properly, because the air conditioner is cooling, if the indoor temperature and the outdoor temperature difference is too large, it is easy to make people "air conditioning disease", it is recommended to set the temperature at an acceptable temperature.

2. When air conditioning and cooling, the position of the air deflector is adjusted to the horizontal direction, and the cooling effect will be better.

3, the air outlet is kept smooth, do not pile up the enlarged pieces of furniture to block the air circulation.

4, long time no air conditioning should be unplugged, because the standby state will also consume electricity.

5. Do not place heavy objects on the outdoor unit. There should be no obstructions around the outdoor unit.

6. Before restarting, carefully check whether the drain pipe of the indoor unit is blocked or not, to prevent the phenomenon of water backflow.

7, use a separate socket, can not be shared with other appliances; do not change the operating state of the air conditioner during machine operation.

8. Clean the air conditioner. Wipe the air conditioner with a soft cloth and a small amount of neutral detergent. When cleaning, the water temperature is lower than 40 °C, so as to avoid shrinkage or deformation of the outer casing and the panel.

9. The indoor air inlet filter should be cleaned every 15 days, and the outdoor unit should be regularly dusted.

10. If the air conditioner is found to be faulty, do not use it barely to prevent the fault from expanding. The power supply should be cut off immediately, and the after-sales service should be repaired in time.

11. When the air conditioner is not in use or in case of thunderstorm, the air conditioner should be cut off in time to avoid machine failure caused by continuous connection.

The above is the reason why the air conditioner does not cool the air conditioner and the common sense of the air conditioner. I hope to help you.
