With the warming of the weather, the air conditioning will run again, but the air conditioning is not cooling is our big problem, the customer asked: my air conditioning is not cooling and running normally what is the problem? There are also said that the air conditioning in my home does not run, the wind blowing out is not cool and so on

Many problems are troubling us, the central air conditioning maintenance center to help you analyze the air conditioning often wind several major failures:

(1) The external environment temperature is high, there are more indoor personnel, the air conditioner is working at full load, the wind blowing out of the outlet is cold, but the room temperature does not fall, this is not a fault. When the ambient temperature is higher than 33℃, the external infiltration heat increases, which increases the cooling load of the air conditioner. If there are more people in the room, for example, when the cooling capacity is 2500W in a 20m2 room, if there are 10 people sitting still in the room. Each heat discharge is about 120W, the total of 10 people is 1200W, to use half of the cooling capacity of the air conditioner, then the cooling capacity of the air conditioner is not enough, the room temperature can not fall. This is a normal phenomenon, can not say that the air conditioner is not useful.

(2) The power supply voltage is too low, causing the air conditioner to be difficult to start, stop or fuse blown after starting. This is not a fault, as long as the reason for checking the power supply is that the power grid voltage is too low, the user should install a power regulator, so that the voltage reaches 220V, so that the air conditioner can be used normally.

(3) Open in the strong cold barrier, the room temperature can not fall, the outlet air volume is not large, which is the air filter ash limit, blocking the air circulation, resulting in the cooling capacity of the machine can not be brought out by the flowing air in time, resulting in insufficient cooling capacity. This is not a fault, as long as you remove the filter to clean, you can return to normal.

(4) Kunshan central air conditioning maintenance when open in strong cold gear, the fan runs at high speed.

(5) Improper adjustment of the thermostat does not play a large function of refrigeration, resulting in a cold room, which can be solved after adjusting the thermostat,

(6) Heat pump type air conditioner, in the colder winter cooling heat effect is not ideal, which is also a normal phenomenon. For the heat pump type air conditioner without automatic defrosting, the low ambient temperature it uses is 5 ° C above zero, below this temperature is not heating or the effect is very poor, this is because the frost on the external heat exchanger blocks the air flow, can no longer inhale heat from the outside; For the heat pump type air conditioner with automatic defrosting, the low ambient temperature it uses is -5 ° C, lower than this temperature can not effectively heat.
