Air conditioning maintenance rules 1, switch secret method
The air conditioner should not be switched frequently. Do not start and shut down the air conditioner frequently because the room temperature has reached or exceeded the required value. Instead, let the air conditioner control the start and shut down through the temperature controller. When the air conditioner is not in use, turn off the power and unplug it. The air conditioner is shut down for whatever reason (such as sudden power failure, artificial shutdown, etc.), because the general air conditioner does not have a time delay for shutdown (delay time is about 3 minutes), then this type of air conditioner can be turned on immediately after shutdown , But it takes 3 minutes to run. But for the air conditioner without time delay, it can not be turned on immediately after shutdown. It must be turned on after about 3 minutes, otherwise it may cause excessive starting current, burn the fuse, and even burn the compressor motor. In particular, pay attention to the effective use of timers. When sleeping and going out, please use the timer to run it only for the necessary time to save power.
Air conditioning maintenance rules 2, temperature secret method
Air conditioning operation should pay attention to carefully adjust the temperature to avoid overheating or cold. If the heating temperature is 2 ℃ lower, it can save about 10% of electricity. Open doors and windows as little as possible while the air conditioner is running. Frequent opening and closing of doors and windows will reduce the cooling and heating effects of the air conditioner and waste electricity. The windows of air-conditioned rooms should be covered with curtains. In the winter, let the sunlight shine into the room during the day and cover it with curtains at night to prevent heat loss. Especially in summer, blocking direct sunlight can make the air conditioner about 5%. In addition, houses with good thermal insulation are the most energy efficient. Therefore, it is recommended to use thermal insulation materials when the family builds a house, builds or decorates it.
Air conditioning maintenance rules 3, filter secret method
Among all household appliances, air-conditioning dust pollution is the most serious, and the cleaning of air-conditioning is also the most easily overlooked thing. Some users use it for many years after installing the air conditioner, and never clean it until it breaks down. A considerable part of the air conditioners that are being repaired are damaged prematurely due to lack of cleaning and maintenance. Therefore, air conditioners generally need to be cleaned and maintained before use in summer or after use in autumn. Especially the maintenance of the filter. In recent years, the use of long-term deodorizing air-conditioning filter filters has greatly improved the fresh air quality of air-conditioning. For the cleaning of this type of air filter, be careful not to touch the metal part of the indoor unit when disassembling, because there is a possibility of being scratched. After removing the air filter, pat gently or use an electric vacuum cleaner to clean it. If the filter is too dirty, it can be washed with water or neutral detergent, but it must not be washed with hot water above 50 ℃ to avoid deformation. Do not use sponge to clean, otherwise it will damage the surface of the filter. After washing with clean water, let it dry in the shade. Do not expose it to sunlight or dry it by the fire, because it may cause deformation. Install the air filter after air-drying in place of the air conditioner, and the whole maintenance process is completed. The air filter is a consumable. It is replaced approximately every four months. If the filter is clogged, it will reduce the filtering capacity and reduce the amount of air circulation, thereby reducing the cooling and heating effects.
Air conditioning maintenance rules 4, component secret method
In the daily air-conditioning operation, pay attention to protect the cooling fins of the condenser and evaporator. The cooling fins of the condenser and the evaporator are made of 0.15 mm aluminum sheets that are inserted into the copper tube and expanded. They can't withstand collision. If the cooling fins are damaged, the cooling effect of the air conditioner will be affected and the cooling efficiency will be reduced. In addition, the refrigeration system must be protected. If the components or connecting pipes of the refrigeration system are damaged, the refrigerant will leak and the air conditioner will not be able to cool. Every six months, the outdoor cooler should be cleaned with a long brush for dust. Dismantle the movement every year and inject appropriate lubricant into the fan motor bearings. The refrigeration system does not need to be treated, as long as the external dirt is removed. Use water-cooled air conditioners. When the refrigeration system is working, the water source must not be turned off. For air-cooled condensers installed outdoors, remove dust every 1-2 months. When shutting down in winter, the water stored in the water-cooled condenser should be drained to prevent frost cracking. In addition, the air conditioner should correctly select the fuse (fuse). Choose the specifications of the fuse according to the rated current indicated in the product manual. If it is too large, it will not be safe. If it is too small, it will often break.
Air-conditioning maintenance rules
Do not block the air outlet of the outdoor unit. When the outdoor unit's air outlet is covered by items, the cooling and heating effect is reduced, and electricity is wasted. Good at using wind direction adjustment. The wind direction plate is downward when heating, and the wind direction plate is horizontal when cooling, the effect is better.
Regular maintenance of the air conditioner can maintain the good use effect and normal life of the air conditioner. The following work should be done:
(1) Always check whether the contact between the plug and the socket of the air conditioner is good. If the power lead or plug is hot when the air conditioner is running, it may be that the electrical wiring is too thin or the plug and socket are in poor contact. solve.
(2) Always observe whether there is refrigerant leakage at the interface of the refrigerant pipe of the air conditioner (mainly refers to the split air conditioner). If oil stains are found, it indicates that there is refrigerant leakage, and it should be dealt with in time to avoid long-term leakage and insufficient refrigerant quantity, which affects the cooling (heat) effect of the air conditioner and even damages the compressor.
(3) Clean the dust on the air conditioner panel and cabinet frequently. Generally wipe with a dry cloth. Wipe first, then wipe off the detergent with a damp cloth. Never use hot water, gasoline, volatile oil and corrosive solvents above 40 degrees to wipe the air conditioner panel and cabinet. Do not use hard bristle brush to scrub the air conditioner, so as not to damage the shell, causing paint peeling, fading, etc.
(4) Regularly clean the condenser and evaporator coils of the air conditioner. You can use a brush and a vacuum cleaner to clean the dust on the coil. Note that the brush and vacuum cleaner should be cleaned in the vertical direction of the coil during cleaning, and do not clean in the horizontal direction, so as not to damage the ribs of the coil.
(5) Clean the air filter of the air conditioner regularly. It is usually cleaned every 2 to 3 weeks. When cleaning, pull out the filter and use a dry soft brush to filter the dust on the filter. It can also be cleaned with clean water to filter the dust on the net. Let it dry before using it in the air conditioner. For environments with a lot of dust, the filter screen should be cleaned more often to avoid too much dust on the filter screen and affect the ventilation of the air conditioner.
(6) When the air conditioner is to be shut down for a long time (such as the seasonal shutdown of the air conditioner), the air conditioner should be fully cleaned. After cleaning, only turn on the fan of the air conditioner, run it for about 2 to 3 hours to dry the inside of the air conditioner, and then cover the air conditioner with a dust cover.
(7) For units with more air conditioners, every 2 to 3 years, professional air conditioner cleaning companies should be asked to clean the heat exchanger surfaces of the outdoor and indoor air conditioners to improve the heat exchange efficiency of the heat exchanger , To achieve the purpose of energy saving.
