What should I do if the refrigeration effect of Shanghai Mitsubishi air conditioner is not good? Samsung air conditioning refrigeration has no effect

Mitsubishi air conditioning motor will start the conveying function of freon after it is started. The general reason why freon is not enough is the normal situation after three or four years of air conditioning.

If you find that the cooling effect of the air conditioner at home is not as good as before, that's probably the reason. Solution: buying air conditioners generally contains freon. You can add it yourself at this time. If not, you'd better find a maintenance master to help you. Another thing to remind here is not to use freon excessively, which will be counterproductive. ? The third reason why the air conditioner does not cool is that the copper tube between the outdoor unit and the indoor unit is too long. ? Some friends think that the outdoor machine is too noisy, so they deliberately move it to a far place, which increases the transmission distance and leads to the decline of the refrigeration effect of air conditioning. In addition, it also increases the installation cost, which is not worthwhile. Due to the unreasonable demand or installation of air conditioner, the ventilation pipe is too long, the heat transfer efficiency is low, and the air conditioner does not cool. Solution: Try to shorten the length of copper tube between outdoor unit and indoor unit of air conditioner? The fourth reason why the air conditioner is not cooled: the air conditioner is not cleaned and maintained for a long time, resulting in no cooling. ? After buying the air conditioner, everyone felt that they could enjoy everything. Actually, it is not. We have to stop taking care of air conditioning in many ways. One of them. Because the outdoor unit of the central air conditioner is installed outdoors, it is easier for everyone to ignore it. After being used outdoors for a long time, a lot of dirt such as dust and dregs will be adsorbed on the radiator, which will make the radiator have poor heat dissipation effect and it is too late to adjust the cooling.
