Maintenance of air conditioner: maintenance before starting.
Usually, household air conditioners are turned off in September, turned on in May and June of the following year, and stopped for more than half a year. Therefore, a comprehensive "diagnosis" must be made before the air conditioner is turned on to check whether there is a "fault" in the air conditioning equipment. According to the inspection results, under the guidance of professional and technical personnel, do a good job in maintenance and cleaning, including the casing, fuselage and filter screen of outdoor and indoor units, and then start trial operation to observe the cooling speed and effect.
Air conditioning maintenance: maintenance during startup.
After the air conditioner is turned on, it is necessary to determine the maintenance frequency during the start-up of the air conditioner according to various factors such as environmental conditions, climate conditions, start-up time, surrounding dust, air cleanliness, indoor cleanliness and so on. Poor environmental conditions, hot weather, outdated air conditioning, long start-up time of air conditioning, and increased maintenance times during air conditioning start-up, generally once a month and a half. If the environmental conditions are good, the air conditioner is relatively new, there is less dust in the air, and the air conditioner can be turned on reasonably and can be used alternately with the electric fan, then the maintenance cycle can be extended appropriately, from air conditioner on to air conditioner off 1-2 times. Maintenance should be careful and meticulous, leaving no dead ends. Reach the standard, improve the cooling speed and effect, and achieve energy saving, freshness and comfort.
Air conditioning maintenance: maintenance after shutdown.
It is a perennial law to turn on the air conditioner when the weather gets warmer and turn off the air conditioner when the weather gets cooler. Pay attention to the comprehensive and detailed inspection of outdoor units and indoor units before the air conditioner is turned off. Maintenance, maintenance and cleaning should be done one by one. Leaky links should be tightened and strictly checked. After the above steps are completed, cover the air conditioner to prevent dust pollution, prevent the air conditioner from dripping into water, keep it clean, prepare for reuse next year, save energy and prolong the service life of air conditioning equipment. Focus on protecting high-quality distributors and cabinets of well-known brands, and give full play to the energy-saving effect.
Air conditioning maintenance: air conditioning maintenance in general time.
1. Remove the sundries in the vent to ensure normal ventilation. Observe whether the outdoor rack is loose, and clean the outdoor ventilation net cover for foreign objects. At the same time, keep the vents open.
2. Clean the surfaces of indoor and outdoor heat exchangers to improve the efficiency of heat exchangers. When cleaning the indoor heat exchanger, carefully remove the panel, scrub it with a soft rag, and gently scrub the heat exchanger of the indoor unit with a small brush to remove the harmful accumulation of dust and breeding bacteria. However, it should be noted that the heat sink is very thin aluminum, which is easy to deform after being stressed, so brush it carefully.
3. Remove the dust from the filter screen. When cleaning the filter screen, cut off the power supply first, and then open the air intake grille; Take out the filter screen, clean the filter screen with water or vacuum cleaner, the water temperature should not exceed 40 degrees, clean it with hot wet cloth or neutral detergent, and then wipe it with dry cloth. At the same time, it is not allowed to clean the filter screen with pesticides or other chemical cleaners.
4. Remove dirt and deposits from the drainage part. The drainage part is easy to deposit dirt, so it must be disinfected thoroughly on a regular basis to ensure smooth drainage and prevent bacterial reproduction.
5. Check others. Comprise a power cord, a plug board and a switch; Check the status of consumable parts, such as air deflector, sterilization and dehumidification, photocatalyst, etc. , to ensure that the air conditioner is in good condition.
Air conditioning maintenance: air conditioning maintenance at special time.
In March-May and September-165438+10 when the temperature is moderate, people usually leave the air conditioner in a non-working state. In the season when the air conditioner is not used, the power supply of the air conditioner should be cut off first, but it is best to keep the usage once a month to prevent the lubricating oil in the machine from condensing due to long-term non-use. At the same time, in order to ensure the long-term high-speed operation of the air conditioner and the extension of the use task, attention should be paid to the maintenance when the air conditioner is stopped and started to use.
1, after the season. Before stopping using the air conditioner, you can set the air conditioner to the air supply state on sunny days, and turn on the air conditioner for about half a day to make the air conditioner completely dry; At the same time, the dust filter, indoor unit and outdoor unit should be cleaned.
2. Before the start of the season. Check whether there are obstacles in the air inlet and air outlet of indoor and outdoor units, so as not to reduce the working efficiency of air conditioning; Install dust filter to prevent dust from entering the machine and causing damage or failure of the machine; The remote control should be cleaned with a dry cloth, not with glass cleaner or cloth containing chemicals. After cleaning, two new batteries of the same model should be installed.
Matters needing attention in air conditioning maintenance
1, the power supply voltage should not fluctuate too much (10% fluctuation is allowed), the air conditioner should be powered by a dedicated line, and the single-phase three hole socket should be used, and the plug should be plugged to the end.
2. The casing of the indoor unit should be cleaned frequently. Generally, it can be wiped clean with a clean dry cloth or neutral detergent. It is absolutely not allowed to rinse directly with water. If it is wiped with a cloth, it should be done after the power is cut off.
3. The indoor temperature should not be adjusted too low, otherwise it will be harmful to human body, and the set temperature should be adjusted appropriately.
4. If you feel that the indoor temperature is too high, you can lower the set temperature appropriately.
5. The effective use of timer can achieve the effect of energy saving and comfort.
6, air conditioning room personnel should not be too much, too crowded, otherwise the cooling capacity is insufficient, the temperature is difficult to drop;
7. Don't switch the doors and windows of the room frequently, and people don't go in and out frequently to avoid the loss of air conditioning;
8. The glass window must be closed tightly and tightly, and double white curtains should be hung inside to reflect the partially penetrated light and heat;
9. The window can be opened briefly during indoor ventilation, and the window opening time generally does not exceed 10 minute;
10, air conditioning air filter should be cleaned regularly, otherwise the airflow is blocked, resulting in insufficient air volume and rising room temperature;
1 1. Adjust the temperature during sleep, and the air conditioner can automatically adjust the sleep temperature;
12. The outdoor unit of the air conditioner should be installed firmly to reduce vibration and noise, and sufficient space should be left in front of the suction and exhaust ports of the condenser to facilitate ventilation. If the wind is blocked, the condensation pressure will increase, leading to shutdown;
13, there should be no obstacles in front of the indoor unit of the air conditioner, otherwise it will affect the wind;
14. When the air conditioner is just running, you can adjust the selector switch to high speed for rapid refrigeration, and then adjust it to medium speed and low speed after the temperature drops;
15, the ventilation switch of window air conditioner can be used, but the ventilation time does not exceed 15 minutes;
16, too much dust in the outdoor radiator of air conditioner will reduce the efficiency, so the outdoor radiator should be checked and cleaned regularly (it can be blown clean with compressed air after power failure);
17, stick cannot be inserted into the outdoor unit of split air conditioner, otherwise the fan will be stuck or damaged;
18, when you feel that the air conditioner is not ideal, you should consult the instruction manual, analyze whether it is caused by improper use, and correct it after finding out the reason;
19. If the fault cannot be handled by itself, you can find a professional maintenance technician in the original installation department to solve it, or contact the local service personnel of the brand company. You can't fix it yourself or find a non-professional to fix it;
20. Unplug the power when the air conditioner is not in use;
2 1, the air conditioner must be restarted after stopping for three minutes to protect the compressor;
22. Air conditioner with remote control (don't put it where children can easily get it) Don't let children operate as toys to avoid damaging the machine.
The role of air conditioning maintenance
In order to improve the heat exchange efficiency of the outdoor unit of air conditioner and prevent or reduce dust, the indoor unit and outdoor unit system of air conditioner should be cleaned and maintained regularly, and the indoor unit should be cleaned and disinfected. Through the maintenance experience in recent years, the correct maintenance methods can play an excellent role, mainly in:
Regular cleaning and maintenance of air conditioners can improve indoor air quality, prevent the prevalence of diseases and create a healthy indoor environment. After long-term operation of the air conditioning system, a large amount of dust and dirt will accumulate in the filter, filter screen and evaporator of the indoor unit, which is easy to breed and breed germs, and then it will be blown into the room through the tuyere, posing a threat to human health.
2. The cleaning and maintenance of air conditioning system can effectively reduce noise pollution. With the deposition of dust and fibers attached to the filter screen of the air return port of the indoor unit, the filter screen and fins are blocked, and dust gathers on the fan blades, which greatly increases the load of the fan and motor and produces noise.
3. It can improve the heat exchange efficiency of system equipment, improve the cooling and heating effect, and realize effective energy saving. If the evaporator and heat exchanger of indoor and outdoor air conditioners are not cleaned for a long time, the attached dust and dirt will greatly reduce the thermal conductivity of the equipment and seriously hinder the efficiency of cold and heat exchange. At this time, the load of the compressor will increase sharply and the energy consumption will also increase.
4. It can eliminate the hidden trouble of the system, reduce the failure rate, prolong the service life of the equipment, and do more with less money. The composition of air conditioning system is complicated, but it is mainly composed of refrigeration system, driving power supply and control circuit. No matter which part goes wrong, it will affect the normal use of air conditioning. Correct and timely maintenance will find and deal with the hidden dangers of the three components in time, so that the machine is always in good working condition, reducing the failure rate and prolonging the service life.
