Shanghai Dajin central air conditioning maintenance 021 Haida 6 jin9 middle 0 central 0 air conditioning 0 adjustment 1 dimension 9 repair 7 air conditioning uncooled reason is the most common problem in families who have bought air conditioning, most people spend enough money to buy a new air conditioning because their air conditioning is uncooled. The following is to share some of the reasons why the air conditioner is not cooling and the experience of how to deal with it. I hope it can be helpful to you. One of the reasons why the air conditioner is not cooling is that the service life of the air conditioner has expired, the normal service life of the air conditioner has passed, and the air conditioner is aging. I used to buy a second-hand air conditioner in my hometown. I suddenly stopped cooling some time ago. In order to find out why the air conditioner was not cooling, I read a lot of books and searched a lot of information on the Internet. Although I enriched myself with some knowledge about the air conditioner, I couldn't repair the old air conditioner at home, The reason is that the general service life of large household appliances such as air conditioners is between 15 and 20 years. In this year, even if they are repaired, there will be such and such problems. Solution: replace it with a new one. The second reason why the air conditioner doesn't cool is that the refrigerant is not enough, that is, the Freon is not enough, and the snow seed is not enough. The reason why the air conditioner is cooled is because of Freon. When the air conditioner motor is started, the Freon conveying function will be turned on. The general reason why Freon is not enough is also the normal situation after the air conditioner has been used for three or four years. If you find that the refrigeration effect of the air conditioner in your home is not as good as before, that's probably the reason. Solution: when you buy air conditioner, you will get Freon. At this time, you can add it by yourself. If you can't, you'd better ask a repairman to help you. Here is also to remind that do not overuse freon, which will have a negative effect. The third reason why the air conditioner doesn't cool is that the copper pipe between the outdoor unit and the indoor unit is too long. Some friends think that the outdoor unit is too noisy, so they deliberately move the outdoor unit far away, which increases the transmission distance, leading to the decline of the refrigeration effect of the air conditioner. In addition, it also increases the cost of installation, which is not cost-effective. Because of the unreasonable demand or installation of the air conditioner, the ventilation pipe is too long, so the heat transfer efficiency is low, and the air conditioner is not cooled. Solution: try to shorten the length of copper pipe between outdoor unit and indoor unit of air conditioner. The fourth reason why air conditioner doesn't cool is that air conditioner doesn't clean and maintain for a long time, resulting in no cooling. When we buy air-conditioners, we all think that we can enjoy everything. In fact, if not, we often have to stop taking care of air-conditioners in many ways. One of them is that because the outdoor unit of Dajin central air conditioner is installed outdoors, it is easy to neglect it. After a long time of use, the outdoor unit will absorb a lot of st, dregs and other dirt on the radiator, so the radiator has poor heat dissipation effect and has no time to adjust and cool. In addition, the long-term indifference to air conditioning will make the room air unsanitary, more prone to air conditioning disease, increase power consumption, shorten the service life of air conditioning, etc. Solution: clean and maintain the air conditioner, so that the clean outdoor unit can dissipate heat later. The fifth reason why the air conditioner doesn't cool: the family voltage is not enough, the supply voltage is abnormal, sometimes high and sometimes low.

It depends on which region you are from.

you can find the dealer who installed it for you.

you can also consult Daikin's after-sales service.

generally, after-sales and dealers are the same company

7. The transmission medium of air-cooled heat pump unit is usually water solution. It generates air-conditioning cold / hot water through the outdoor host, which is transmitted to the indoor terminal devices by the pipeline system; The heat exchange between cold / hot water and indoor air at the terminal device proces cold / hot air to eliminate the cold / heat load of the room. It is a type of air conditioning system that proces cold / heat in a centralized way, but disperses the load of each room
the indoor end device of the system is usually fan coil unit. Generally, fan coil units can adjust the fan speed (or the amount of water passing through the coil through the bypass valve), so as to adjust the cold / heat into the room. Therefore, the system can adjust each air-conditioning room separately to meet the different air-conditioning needs of each room, and its energy saving is also good. But the cold and hot water transmission and distribution system occupies a certain installation space.

the air conditioning compressor is used to compress and drive the refrigerant in the air conditioning refrigerant circuit. Air conditioning compressor is generally installed in outdoor unit. The air conditioning compressor extracts the refrigerant from the low-pressure area, compresses it and sends it to the high-pressure area for cooling and condensation. The heat is emitted into the air through the radiator, and the refrigerant also changes from gaseous state to liquid state, and the pressure increases
the working circuit of air conditioning compressor is divided into evaporation area (low pressure area) and condensation area (high pressure area). The indoor unit and outdoor unit of air conditioner belong to low pressure or high pressure area respectively (it depends on the working state). The refrigerant flows from the high-pressure area to the low-pressure area and is injected into the evaporator through the capillary tube. When the pressure drops suddenly, the liquid refrigerant becomes gaseous immediately and absorbs a large amount of heat in the air through the radiator. In this way, the air-conditioning compressor works continuously, continuously absorbs the heat at one end of the low-pressure area into the refrigerant, and then sends it to the high-pressure area to disperse into the air, which plays the role of regulating the air temperature.
