In the hot summer, central air conditioning is undoubtedly the best cooling weapon, but during the use of central air conditioning, some minor failures are inevitable, which have a great impact on the application effect. For example, how to cool only blowing air when the central air conditioning is in cooling mode? How to solve it? The following network editor explains the relevant knowledge in this aspect, let’s take a look together.

How to cool only blowing air when central air conditioning is in cooling mode

I. The cause of central air conditioning lacking refrigerant

In fact, the lack of refrigerant in central air conditioning is the most common cause of poor cooling performance. Nowadays, most central air conditioners use refrigerant as the refrigerant. If it is found that the cooling effect of the central air conditioner is not good, then it can be considered whether the central air conditioner is lacking in refrigerant. To deal with the lack of refrigerant in central air conditioning, it is only necessary to find a professional maintenance staff to add refrigerant. Generally, the cost of adding refrigerant to one air conditioner is about 15 yuan, and the charge varies with the location, so the price of adding refrigerant is different.

II. The cause of refrigeration pipe damage

Poor cooling performance of the air conditioner may also be caused by a damaged refrigeration pipe. If the refrigeration pipe is damaged, you can find a maintenance person to find a refrigeration pipe, or if you are good at doing it yourself, you can replace a new refrigeration pipe yourself.

III. The cause of poor installation location

Attention should also be paid to the installation location of the air conditioner. It is necessary to pay attention not to repair the air conditioner in a place with direct sunlight in the early stage of air conditioner maintenance, as direct sunlight and long exposure can cause the outdoor unit to exceed the normal working environment, resulting in poor cooling effect of the central air conditioning.

IV. The cause of central air conditioning being dirty

In the application of central air conditioning, attention should also be paid to cleaning the working condition. If it is found that the air conditioner is not cooling well and only blowing air, it is necessary to first open the casing of the central air conditioner to see if the inside is too dirty. If it is found that there is a lot of dust inside, then it is the dust in the central air conditioner that blocks the air outlet, causing poor cooling performance. At this time, just take out the dust net of the central air conditioner and clean it thoroughly.

V. The cause of insufficient working voltage of central air conditioning

The insufficient working voltage of central air conditioning is an indirect reason for poor cooling performance. The standard working voltage for central air conditioning in our country should be 220V, while the phase voltage in our country is 220V. In a power supply and distribution system where the phase voltage is 380V, if the working voltage is above 200V, almost all refrigeration compressors can start. However, if the working voltage is above 180V, 70-80% of household appliances in our country can start, and when the working voltage is above 160V, only some can start.
