Hang Zhou Dawn Air Conditioning Co .,Ltd.

Recently, the Shanghai Business Association to pay electric appliances, said its "home appliance repair Link" platform recently received the total air-conditioning repair phone repair 41%. Difficulties children winter heating air condenser coils, or the use of reason is the quality? What are errors use of air conditioning?
A misunderstanding
Refrigerant for a one-year
In the "home repair Link" call consultation, consumers are often referred to the same question: "Is freon a year for a change?"
Maintenance experts pointed out that as the machine condition and use of different conditions, each evaporator coils refrigerant leakage is not as much air conditioning do not have four or five years to add refrigerant, the so-called "year of a change" is not science.
Consumer alerts: freon and other refrigerants in air conditioning cooling, heating must be media. Do not add refrigerant should not be taken for granted or biased or small ads, the best professional home inspection your current air conditioning system pressure, air inlet and outlet of the temperature and other indicators. If you really need to add, regular maintenance will go first to the leak, because the case did not find the leak, the refrigerant will be added soon leaked.
Error II
And off more energy
Among the air-conditioning failure, frequent burning fuse switch failure caused by a lot. Asked why switch off air conditioning to open, many consumers have said is out of power considerations. In fact, air conditioning and heat exchanger are most afraid of frequent switching, so that not only power, but more power. Generally do not have the air conditioning down the time delay, stop immediately after the boot, due to excessive current burning fuse or even burn the compressor motor.
Consumer alerts: Do not want to room temperature has reached the value of frequent switching on air conditioning. Even if the shutdown and restart, have to wait for 3 minutes. In fact, the air-conditioning, power good habits is a must, such as lower heating temperature 2 ℃, can power about 10%. In addition, the fine weather let the sun shine into the room, open air curtains at night, but also warm energy.
Three Mistakes
Washed clean the filter only
In all home appliances, air conditioners dust pollution is the most serious neglect of some clean air because the owner has caused failure. General air-conditioning in summer or autumn before use after use in need of a cleaning and maintenance.
Experts point out that, in addition to a few years the "big wash" the best professional maintenance person, please come, the usual cleaning, users can complete themselves. Filters require frequent cleaning, general cleaning two or three weeks time. Out of the filter, dust with a dry soft brush, or the temperature below 50 ℃, washed, dried installed. Photocatalyst in the use of air conditioning in the front but also in the sun more than 10 minutes. Condenser and evaporator coil cleaning can be vertical brush and vacuum cleaner.
Consumer alerts: If you are in dusty environment, air conditioning filters have to wash to avoid too much contact with dust, the amount of ventilation air. In the larger regional fumes, air-conditioning required of the professionals to clean.
Four Mistakes
Awning close to the body outside the machine
Close air awning to do, both wind --- delivery of goods but also found that some people give maintenance personnel air conditioning unit Slim custom "tight little coat" or "Using" external drive to put some items. In fact, if the location is good hanging outside the machine, little need for the awning, as its initial design to add a waterproof, anti-acid, rust and other functions. In addition, the air conditioning unit housing are mostly plastic, pressure limited, compression of the panel easily deformed.
Consumer alerts: often in the sun for the external drive, do need to install the awning, but the awning is too small to affect the air conditioning heat exchange to determine the best awning according to the instructions from the air conditioning unit around, the distance. Meanwhile, heat with cold air modulation is much more easily affect the pressure outside the machine by heating, and even damage to the internal critical components.
