How to maintain the air conditioner

1. What are the benefits of air conditioning maintenance? 1, Prevention of air-conditioned diseases People who work and live in air-conditioned environment for a long time will have symptoms such as stuffy nose and dizziness because the air is not circulating and the environment is not improved. Sneezing, tinnitus, fatigue, memory loss and other symptoms. It may even lead to symptoms related to skin allergy characteristics, such as tight and dry skin, skin allergy, poor skin and so on. This phenomenon is called "air conditioning syndrome" or "air conditioning disease" in modern medicine. 2. Extend the service life of the air conditioner. After the air conditioner is used for a period of time, due to the electrostatic effect and repeated air circulation, a large amount of dust and dirt accumulate on the surfaces of the filter plate, radiator and evaporator fins, causing airflow blockage, which leads to a decline in the cooling and heating effect. Increase power consumption and noise, even seriously damage the compressor and increase the failure rate. Reduce the service life of air conditioners. But also produce peculiar smell, breed bacteria, mites, etc., and endanger people's health. 3. Save electricity resources In the process of repeated operation of the air conditioner for countless times, a large amount of dust and liquid smoke mixed in the air will wrap the fins layer by layer, which will seriously block the tiny gaps between the fins and affect the heat dissipation of the fins, thus leading to an increase in condenser pressure, an increase in compressor motor current, a doubling of operation time and a significant increase in power consumption. (When the heat sink is in a clean state, the heat dissipation is good, the room temperature drops rapidly to the set temperature, and the compressor automatically stops working; According to the experimental results, when the dirt on the heat sink reaches the thickness of 0.30 mm, the working time of the compressor will double and the power consumption of the air conditioner will increase by about 2.4 times. For example, before cleaning a room, it takes more than ten minutes to drop to the set temperature; It only takes seven minutes to cool to the set temperature after cleaning, so the compressor can work for three minutes less, thus saving 30% electricity. At present, the current situation in China is that a large number of air conditioners have poor refrigeration effect, even extend the compression time and waste electricity. Through cleaning, the air conditioner can restore the normal refrigeration effect, shorten the compression time and save electricity 10-30%. Second, how often should the air conditioner be maintained? The air conditioner maintenance manual states that it is best to clean the air conditioner 2-3 times a year. Under normal circumstances, it is reasonable to clean the air conditioner once before starting, once in the middle and once when shutting down. Sometimes, when the air conditioner is turned off, it will go through major cleaning processes such as maintenance, maintenance and cleaning. And the air conditioner is covered with a range hood. When the air conditioner is turned on in the second year, it is cleaner and the filter screen is cleaner. At this time, the air conditioner is cleaned twice a year, which has a good effect, saves labor and costs, reduces operating costs, and does not affect the refrigeration effect. Therefore, the air conditioning maintenance time is generally in April and 10 every year. The key to air conditioning maintenance: air conditioning cleaning air conditioning cleaning should include three parts. The first part is the shell and exposed part of the air conditioner body, which is easy to be polluted; The second is the cleaning of the filter screen, which is the most important part of the filter element; The third part is the condenser and evaporator, which are combined with maintenance. 1. Cleaning of air-conditioning housing and corresponding components Regarding the cleaning of air-conditioning housing and corresponding components, a considerable part of air-conditioning can be cleaned by adding a little soap powder and detergent to clean water or special air-conditioning cleaning solution. 2. Cleaning of filter screen The key part of cleaning of household air conditioner is cleaning of filter screen. Open the housing of the indoor unit and observe whether there is dust and smell on the filter screen of the indoor unit. If there is too much dust or smell, please clean the filter. When cleaning the filter, cut off the power first, then open the panel and take out the filter. Clean the filter screen with a brush, and then rinse it with clean water. When it is too dirty and greasy, it can be cleaned with detergent or neutral soapy water, rinsed with water, dried and then packaged. It should be noted that it must not be cleaned with hot water above 40℃. Do not use washing powder, detergent, gasoline, banana oil, etc. So as to avoid deformation of the filter screen. In addition, after rinsing with clear water, dry it with a soft cloth or put it in the shade to dry. Do not expose yourself to the sun or dry in an open flame such as a stove to avoid deformation of the filter element. After installing the filter screen, plug in the power supply for 3-5 minutes, set the remote control in refrigeration mode, set the temperature at the lowest state, and start the machine. After debugging the air conditioner to check the hidden trouble, set the wind speed switch of the remote controller to run in different gears, and observe whether there is abnormal sound in the indoor unit. Turn on the machine for about 15 minutes, and observe whether the fan of the external machine works normally and whether the external machine has abnormal sound. Turn on the machine and run for about 30 minutes, and observe whether there is cold air at the outlet of the indoor unit, whether there is condensed water flowing out of the outlet pipe of the outdoor unit and whether the running water is smooth. 3. Clean the condenser and evaporator parts. Condenser and evaporator are relatively rare, and combined with maintenance, it is equivalent to cleaning a small system, which belongs to a relatively large "operation". Five rules of air conditioning maintenance 1. Don't switch the air conditioner frequently. Don't turn on and off the air conditioner frequently because the room temperature has reached or exceeded the required value, but let the air conditioner be controlled by the thermostat. When the air conditioner is not in use, turn off the power and unplug it. No matter what causes the air conditioner to shut down (such as sudden power failure, artificial shutdown, etc.). ), because there is no delay device for shutdown (the delay time is about 3 minutes), this air conditioner can be turned on immediately after shutdown, but it will run for 3 minutes. However, the air conditioner without delay cannot be turned on immediately after being turned off, and it must be turned on for about 3 minutes, otherwise the starting current may be too large, which may burn out the fuse or even the compressor motor. Pay special attention to the effective use of timers. When sleeping and going out, please use the timer to run only during the necessary time to save electricity. Second, the temperature secret method air conditioning operation should pay attention to carefully adjust the temperature to avoid overheating or supercooling. If the heating temperature is 2℃ lower, it can save electricity by about 10%. Try to open as few doors and windows as possible when the air conditioner is running. Frequent opening and closing of doors and windows will reduce the cooling and heating effect of air conditioners and waste electricity. The windows of air-conditioned rooms should be covered with curtains. In winter, sunlight enters the room during the day, and curtains are used at night to prevent heat loss. Especially in summer, air conditioning can save about 5% electricity by blocking direct sunlight. In addition, a well-insulated house saves the most electricity. Therefore, it is recommended to use thermal insulation materials when building, adding or decorating houses. Third, the filter screen secret method In all household appliances, the dust pollution of air conditioners is the most serious, and the cleaning of air conditioners is also the most easily overlooked thing. Some users use the air conditioner for many years after installing it, and don't clean it until it breaks down. Due to the lack of cleaning and maintenance, quite a few air conditioners sent for repair are damaged prematurely. Therefore, air conditioners generally need to be cleaned and maintained before use in summer or after use in autumn. Especially the maintenance of filter screen. In recent years, the fresh air quality of air conditioning has been greatly improved due to the adoption of long-term deodorizing air conditioning filter. When cleaning this kind of air filter, be careful not to touch the metal part of the indoor unit when disassembling, because it may be scratched. After removing the air filter, gently bounce it or use an electric vacuum cleaner to clean it. If the filter screen has too much scale, it can be cleaned with water or neutral detergent, but hot water above 50℃ cannot be used to avoid deformation. Do not use sponge to clean, otherwise it will damage the surface of the filter screen. Rinse with clear water, and then air dry in the shade. Never expose or dry in the sun, because it may cause deformation. Put the air-dried air filter back to the original position of the air conditioner, and the whole maintenance process is completed. Air filters are consumables and should be replaced about every four months. If the filter screen is blocked, the filtering capacity will be reduced and the air circulation will be reduced, thus reducing the cooling and heating effect. Fourth, the secret method of components In the daily air conditioning operation, attention should be paid to protecting the cooling fins of the condenser and evaporator. The heat sink of condenser and evaporator is made of 0. 15mm aluminum sheet inserted into copper tube and expanded, which can't stand collision. If the heat sink is damaged, it will affect the cooling effect of the air conditioner and reduce the cooling efficiency. In addition, we must protect the refrigeration system. 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. Dismantle the movement every year and inject proper amount of lubricating oil into the bearing of the fan motor. The refrigeration system does not need to be treated, just remove the dirt on the surface. Use water-cooled air conditioner, and don't turn off the water supply when the refrigeration system is working. For air-cooled condensers installed outdoors, dust should be removed once every 1-2 months. When stopping in winter, the water in the water-cooled condenser should be drained to prevent frost cracking. Also, the air conditioner should choose the fuse correctly. Select the fuse specification according to the rated current indicated in the product manual. If it is too big, it is not safe. Too small often breaks down. Fifth, the wind training method should not block the air outlet of the outdoor unit. When things are placed in the outdoor air outlet for shelter, the cooling and heating effect is reduced and electricity is wasted. Be good at using wind direction to adjust. When heating, the air guide plate is downward, and when cooling, the air guide plate is horizontal, and the effect is better. Tip: Air-conditioned rooms are generally dry. If people stay for a long time, they will feel dry throat and thirst, and human skin will also be affected by the imbalance of pH. The prevention method is to pay attention to the water supplement inside and outside the body. Air conditioning fans can save more electricity when used together. In the hot summer, the temperature remains high, but the electricity bill will rise. How can I save electricity and enjoy the cool? Consumers came up with the method of air conditioning and distribution fan, and experts also affirmed it. The day before yesterday, Mr. Guo of Hankou bought an air conditioner in an electronics store, and then bought an electric fan, saying it was used in conjunction. The person in charge of the store said that since the summer, the sales volume of fans has been above 100 every day, and many consumers are buying air conditioners and fans. In this regard, Yang Lu, deputy director of the Provincial Household Appliance Maintenance Industry Management Office, and other professionals said that the combination of air conditioners and fans can really save electricity and make people comfortable. According to reports, the cold air delivery radius of split air conditioners is about 1.5 meters, and even cabinet air conditioners are generally only 2.5 meters, so many consumers will feel uneven indoor heat and cold. Some people often lower the cooling temperature of air conditioners in order to cool down quickly, but this actually increases the power consumption. According to the test, every time the air conditioning temperature drops by one degree, the power consumption increases by about 10%. Therefore, if the temperature of the air conditioner is properly raised by one or two degrees, plus the fan, the human body may feel fresher, but the power consumption will be reduced. Because the power of the air conditioner is above 1000 watts, and the power of the fan is generally around 50 watts. Experts believe that after turning on the air conditioner for a period of time and then speeding up the indoor air flow through the fan, experts can also teach you the common sense of using the household air conditioner at room temperature: how to use the household air conditioner? When using air conditioning, the most important thing is to keep the necessary ventilation. During the whole day's use, turn off the power for many times and open the window for ventilation. Attention should be paid to maintaining the concentration of indoor oxygen. At present, there is no clear ventilation time standard, but it is suggested that the ventilation time is 15-30 minutes each time. At the same time, it must be cleaned before reuse in summer, and it is also important to maintain environmental hygiene and personal hygiene. In addition to maintaining ventilation when using the air conditioner, it must be cleaned before using it, mainly the cleaning of the filter screen. Ordinary families can insist on cleaning once a month. When it is cold, the air conditioner should also be cleaned. The air conditioning temperature should not be too low, generally 24-26 degrees. Too low temperature can easily lead to respiratory diseases. Many consumers use air conditioners by mistake. They have used the air conditioner for many years, and they don't even know how to remove the filter. They blindly asked the cleaning staff to clean and disinfect it. The cleaning of air conditioners focuses on long-term maintenance, and cleaning once can't solve the problem. When stopping, air supply should be used to keep the indoor unit dry. When installing, the outlet pipe should be unobstructed to avoid water accumulation and bacterial growth. Two: should household air conditioners be disinfected? For special places such as hospitals, air conditioners should be cleaned once a week, and condensate water, filters and pipes of air conditioners in hospital isolation areas should be disinfected to avoid cross-infection. However, if ordinary families are undoubtedly like patients, air conditioners do not need to be deliberately disinfected, but cleaning is still necessary. There is no need to turn pale at the mention of SARS, so as not to cause unnecessary panic and accidents. In Xiamen, drivers have drunk oxyacetic acid. In some areas, there are jokes that burning incense and setting off firecrackers can prevent SARS. It is necessary to prevent SARS scientifically. During disinfection, peracetic acid can be diluted to a concentration of 0.5%-2%, and the filter screen can be soaked for half an hour. Families can operate on their own, and the cleaning standards are not high, so they don't need to be as strict as hospitals. Cleaning and disinfection of household air conditioners can be divided into small washing and large washing. Many times, as long as the air conditioning filter is cleaned regularly, the hygiene requirements can basically be met. Taking this as a light washing is simple and easy, and it is more suitable for consumers to operate at home. In addition, according to the dust in the living environment, we will teach you to clean and disinfect thoroughly twice a year 1-2 times, which can be used as the main washing and handed over to professional service personnel. Efficacy of household air conditioner: negative ion air conditioner can neutralize the positive charge in air dust and has bactericidal effect; Ventilation and air conditioning make indoor dirty air flow out and fresh air flow in; Catalytic air conditioning can remove formaldehyde released from furniture and decorative materials; Sterilization enzyme air conditioner, sterilization through sterilization enzyme filter screen. Introduction of home central air conditioning The concept of home central air conditioning originated in the United States and is an important part of commercial air conditioning. The domestic central air conditioner improves the air conditioning and quality of life of all rooms as a whole, and overcomes the shortcomings of split wall-mounted and cabinet air conditioners, such as local treatment of partitioned rooms and uneven airflow. One of the indispensable functional parts of the overall decoration. Through ingenious design and installation, it is the development trend at home and abroad to realize the harmony of beauty, elegance, comfort and hygiene. At present, central air conditioning, independent heating and fine decoration are the three major development directions of high-end properties in China. "Home central air conditioning" is an air conditioner in which a host computer controls different rooms through air duct or drives multiple cold and hot water source terminals to achieve the purpose of indoor air conditioning. Using duct air supply mode, a host computer can control many different rooms and introduce fresh air, which can effectively improve indoor air quality and prevent the occurrence of air conditioning diseases. Another water system can be used. The adjustment method of this central air conditioner is to use the outdoor host to send cooling water to different terminals connected in different areas through water pipes to adjust the indoor temperature. Indoor units can choose horizontal concealed installation, exposed ceiling installation, ceiling installation, wall hanging installation, etc. Various fan-coil units can be independently controlled. Precautions for air conditioning maintenance 1. Don't switch the air conditioner frequently. Don't turn on and off the air conditioner frequently because the room temperature has reached or exceeded the required value, but let the air conditioner be controlled by the thermostat. When the air conditioner is not in use, turn off the power and unplug it. No matter what causes the air conditioner to shut down (such as sudden power failure, artificial shutdown, etc.). ), because there is no delay device for shutdown (the delay time is about 3 minutes), this air conditioner can be turned on immediately after shutdown, but it will run for 3 minutes. However, the air conditioner without delay cannot be turned on immediately after being turned off, and it must be turned on for about 3 minutes, otherwise the starting current may be too large, which may burn out the fuse or even the compressor motor. 2. There are various grilles on the panel of the air conditioner shell, which are easy to accumulate dust. It can be cleaned regularly with soft leather and scrubbed with neutral soap at a temperature not exceeding 40℃. Be careful not to use volatile oil, gasoline and acidic chemicals for scrubbing. 3. Don't put anything on the outdoor unit of the air conditioner, so as to avoid noise from the air conditioner. This will seriously affect the life of the air conditioner. 4. There must be no high-temperature heat source next to the air conditioner to avoid deformation of the air conditioner panel. 5. After the air conditioner runs for a certain period of time, stop and open the window for air.
