Why is the central air conditioner not cold?

1. Why the central air conditioner is not cold

1. The fan coil is blocked and there is a problem with the fan air supply.

2. The water chiller fails, which affects the normal refrigeration.

3. Cold water circulation problem, water level is short or filter screen is blocked. First, check whether the central air conditioner is operating normally, then see if the air conditioning refrigeration environment is closed, and finally find a professional to carefully check the circuit power supply problem.

second, how does the central air conditioner not cool?

1. The most direct reason is the lack of freon, which is also a problem that many people tend to ignore, because whether it is a vertical air conditioner, a cabinet air conditioner or a central air conditioner, Freon is needed to cool or heat.

2. Due to objective reasons, if the power supply voltage is insufficient, the cooling effect will be poor at this time. This kind of problem is most likely to occur especially at the peak of electricity consumption. The unstable voltage will affect the working condition of the internal machine, and the compressor may simply go on strike.

3. In summer, the weather is hot. If the temperature is too high, it will affect the cooling effect of the central air conditioner.

4. I haven't cleaned it for a long time. To be honest, the air conditioner is used frequently because it has entered the summer, but if the air conditioner is not properly maintained, it will also lead to a series of problems.

third, how to maintain the central air conditioner without refrigeration

1. If the refrigerant is not enough, just add refrigerant reasonably, for example, some need to add freon, and some need to add snow seeds. However, when adding, we should also pay attention to the fact that it should be within a reasonable range and cannot be added excessively.

2. If the voltage is unstable, we can install a stabilizer to solve the problem. In addition, if it is a problem of the external environment, or the use environment of the outdoor unit is not good, it should be noted that the outdoor unit should be in a place with good air circulation, and the air conditioner should be cleaned and maintained regularly.
