How to choose air conditioner
Four seas network: summer air conditioning is a necessary household appliance for many families to reduce summer heat. There are many types of air conditioning brands. Many people are worried about buying air conditioning because they don't understand it. So how to choose air conditioning and how to view the configuration of air conditioning? Let's learn about it with four seas editor.
Air conditioner is air conditioner. It refers to the process of adjusting and controlling the temperature, humidity, cleanliness, speed and other parameters of the ambient air in the building / structure by manual means.
Air conditioning selection skills
Brand orientation
There are many air-conditioning brands in the market, domestic and foreign, most of which have their own unique advertising, making it difficult for consumers to choose. It is recommended to select products with strong corporate strength, high brand awareness and perfect after-sales service when purchasing air conditioners. This is based on two considerations:
The first is to ensure the implementation of after-sales service, because air conditioning is a large household appliances, after-sales service is very important. According to the relevant regulations of the state, the compressor should be guaranteed for 3 years, while the competition in the home appliance market is almost white hot. Some manufacturers often have a short survival period, and some of them fall down in three or five years When an enterprise collapses, its commitment will naturally be difficult to implement. If you are greedy and cheap, and buy products with weak corporate strength and low brand awareness, you will have endless troubles.
Secondly, from the perspective of quality, because the air conditioner with strong corporate strength and high brand awareness is relatively stable in quality. Such enterprises not only have strong technical force, but also attach great importance to quality. It is guaranteed to buy such products.
Pick a good businessman
After choosing the brand of air conditioner, consumers have to decide where to buy it. When buying air-conditioners, it is particularly important to choose merchants. Because strictly speaking, air conditioning is a kind of semi-finished product, which can be used not after being bought from the store, but after being installed and debugged by a professional team. If the installation and debugging are not good, it will bring a series of problems, such as the air exhaust is not clean, the pipeline connection leakage, and the human caused fault during debugging. These will not only affect the use effect, but also add a lot of troubles. At the same time, many after-sales service measures of manufacturers also need to be implemented and implemented by businesses. So it's very important to choose the right business.
In the selection of merchants, the insiders suggest that the first thing to do is to select those powerful and influential merchants in the local area, because these merchants have a large number of business varieties and sales, and generally have professional installation and debugging teams, whose installation and debugging quality is guaranteed, and after-sales service is relatively perfect. The second is to choose those long-term air-conditioning dealers, try not to buy from short-term dealers, because such dealers' after-sales service will be greatly discounted.
Volume purchase
Air conditioning is a kind of household appliances with large consumption. If the selected power is too small, it will not work; if the power is too large, it will be wasted. Therefore, when consumers choose air conditioning power, they need to measure the room to buy.
First, don't be greedy. Some consumers like to buy large air conditioners, which is not desirable, because except for some special factors, domestic air conditioners have their use range. Consumers should choose the model of air conditioning according to the area of their own room when purchasing. Generally, the cooling capacity and heating capacity required by the room can be calculated according to the following formula. Cooling capacity room area & times; 140W to 180W; heating capacity room area & times; 180W to 240W. In addition, the room orientation, floor height and sealing degree shall be appropriately increased or decreased.
Second, according to the design of the room, flexible purchase. Do not like some families, buy a large air-conditioner in the living room, to protect the room, not only difficult to protect the whole room, but also cause waste. The reasonable way is to buy some small power air conditioners according to the room type and manage each room. In this way, on the surface, the initial investment is much, but in the long run, it is still worthwhile. For example, a set of 110 square meters of three rooms and two halls can buy a cabinet type air conditioner of two pieces to put in the living room, which can protect both the living room and the dining room, and the bedroom can be divided into one piece of small air conditioner. It's more reasonable than just buying a big air conditioner of 3 in the living room.
Maintenance of air conditioner
Maintenance before startup
Generally, the household air conditioner will be shut down in September, and it will not be started until May to June of the next year, and it will be shut down for more than half a year. Therefore, before the air conditioner is turned on, a comprehensive 'diagnosis' must be made to check whether the air conditioner has any' fault '. According to the results of the check, under the guidance of professional technicians, the maintenance and cleaning work should be done well. This maintenance and cleaning work should be in place, including the shell, body and filter screen of outdoor unit and indoor unit, and then the trial operation should be started to observe the refrigeration speed and effect.
Maintenance during startup
After the air conditioner is turned on, the maintenance times in the process of turning on the air conditioner are determined by many factors, such as environmental conditions, climate conditions, hours of turning on the air conditioner, surrounding dust, air cleanliness, and whether the room is clean or not. The environmental conditions are not good, the weather is hot, the air conditioner is old, the air conditioner has a long start-up time, and the maintenance times in the process of air conditioner start-up increase, usually 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, the air conditioner can be turned on reasonably and used alternately with the electric fan, the maintenance cycle can be appropriately extended, from the air conditioner on to the air conditioner off for 1-2 times. The maintenance shall be serious and careful, and no dead space shall be left. Meet the standard, improve the refrigeration speed and refrigeration effect, achieve energy saving, fresh and comfortable.
Maintenance after shutdown
The weather turns warm, the air conditioner turns on, the weather turns cool, and the air conditioner turns off, which is a perennial rule. Pay attention to a comprehensive and careful inspection of outdoor unit and indoor unit before closing the air conditioner. The maintenance, maintenance and cleaning shall be done one by one, without disconnection. The leaky links shall be tightened and inspected strictly. After the above links are completed, the cover of air conditioner shall be set up to prevent dust pollution, water dripping and inflow of air conditioner, keep it clean and ready for reuse in the next year, so as to achieve cleaning, energy saving and extend the service life of air conditioner. For the high-quality split machines and cabinet machines of well-known brands, we should focus on protection and give full play to the energy-saving effect.
