Does the greater the wind speed of the air conditioner, the greater the cooling capacity? The smaller the wind speed, the smaller the refrigeration capacity. refrigerating output

How to choose air conditioner? When choosing air conditioners, besides brands, how many air conditioners should you choose? This seems to be a small problem in choosing an air conditioner. Too many choices will waste electricity, and too few choices will not be cool. Here Bian Xiao teaches you to simply calculate the square of your home space to choose the number of air conditioners. At the same time, some reference data will be given to find your own satisfactory air conditioner. 1. How many air conditioners should I choose? When choosing air conditioning specifications in stores, you may hear a lot about "horse". "Horse" refers to the input power of air conditioner, and "Watt" refers to its output power. Generally speaking, a horse is equal to 735.5w, and the output power is about three times of the input power. Strictly speaking, the concept of "horse" is not accurate enough, but it is more widely used because it is easier to understand. It should be emphasized that the input power and output power of the machine are different, and the formula cannot be set rigidly. When purchasing the specifications and power of air conditioners, you must consider your own housing area and choose flexibly according to the design of the room. The general rule is that room area ×200W= output power suitable for air conditioning. For example, a set of 1 10 square meters of three rooms and two halls can buy a cabinet air conditioner in the living room, which can protect both the living room and the dining room; It is more reasonable to install 1 small air conditioner in the bedroom than to put 3 air conditioners casually in the living room, instead of thinking that buying a big air conditioner can save the home. Of course, in addition to the room area, there are many factors that will affect the choice of air conditioning. First, the orientation of the room. In summer, the sunny room is hotter than the non-sunny room, so the power should be higher. For example, in a room of 25 square meters, you can choose two air conditioners on sunny days and three smaller ones on sunny days. Secondly, the height of the floor, because the higher the floor, the stronger the wind, and the worse the insulation effect of the room. If you live in a high-rise building, you can appropriately increase the intensity of buying air conditioners. In addition, if you live on the top floor without a roof ridge, the roof will always be exposed to direct sunlight, which will make it more stuffy and the air conditioning power will be improved. The factors that affect the choice of air conditioning are the heat insulation effect of room walls and the number of people living. If the heat insulation effect is poor or the family population is large, it is suitable to choose high-power air conditioning. All these objective factors must be considered before making a choice. 1P cooling area12-17m2, heating area10-1m2. 1P cooling area of cold and warm hanging machine12-21m2, heating area13-18m2. 1.5P cooling area16-28m2, heating area17-23m2; 2P cooling and heating cabinet has a cooling area of 23-30m2 and a heating area of 20-22m2. 2.5P Machine-made cooling area of cold and hot cabinet is 28-35m2, and heating area is 24-28 m2；; The machine-made cooling area of 3P heating and cooling cabinet is 33-42m2, and the heating area is 27-30m2. As for the inverter air conditioner, it can't be calculated by the maximum cooling capacity of the air conditioner because it doesn't work in the maximum cooling state for a long time. It is generally believed that the number of inverter air conditioners should be 145W- 175W per square meter. 2. How to choose the air conditioner with the same price? Although the same kind of air-conditioning products have little difference in appearance and price, they also learn to choose. Now the concept of air conditioning is no longer limited to "adjusting temperature", but has been upgraded to the original meaning of "air conditioning"-"air conditioning", which is actually to adjust the comfort of your room environment. So besides temperature adjustment, it depends on whether it has more functions, such as humidity adjustment, ventilation and so on. Of course, we should also consider the user's own situation, for example, the room of the elderly must choose silent air conditioning; Air conditioners used by pregnant women, children and the elderly should have good ventilation function, because these people are more prone to lack oxygen in air-conditioned rooms. In addition, when choosing inverter air conditioner, it is particularly important to check the power range of air conditioner cooling and heating. The wider this range, the more energy-saving it is. 3. Which is more important, cooling or heating? For the cooling and heating function of air conditioners, there is often a misunderstanding that refrigeration is more important, but in fact it is just the opposite. Judging the quality of an air conditioner can best be reflected from its heating situation. Because in summer, people will feel cool as soon as they walk into an air-conditioned room, and they are not very sensitive to subtle changes in temperature. But in winter, people's bodies release very little heat, so they are particularly sensitive to temperature changes. Therefore, air conditioning should be judged according to the level of maintaining constant temperature during heating, the size of temperature difference and the speed of heating. 4. The meaning of air conditioning (P) related index (1): "P" is the abbreviation of power, and the internationally used "watt" means that the refrigeration capacity of 1P is about 2500W W, for example,1.5 * 25p means that the refrigeration capacity is1. 2P refers to the refrigerating capacity of 2 * 2,500 w = 5,000 w (2) Energy efficiency ratio: (EER) The ratio of refrigerating capacity to effective input power under rated working conditions and conditions. EER= cooling capacity/input power, which can test the performance of air conditioner. The larger the value, the better the system matching, the better the air conditioning performance, the better the cooling and heating effect and the smaller the power consumption. (3) Dehumidification refers to the moisture removed from the air in a closed space, room or area in a unit time, which is called dehumidification. Unit: liter/hour (L/H)(4) Rated voltage: refers to the allowable power supply voltage value or allowable power supply voltage range specified by the air conditioner manufacturer when the air conditioner product leaves the factory. (5) Noise types: aerodynamic noise, mechanical vibration noise and electromagnetic noise sources: fans and compressors. The noise range is about 50 decibels indoors and 60 decibels outdoors. (6) Rated power: When working under normal working conditions, the consumed electric power is the total power allowed by the air conditioner. 5. On-site 1 Select the details that should be paid attention to in air conditioning. Appearance inspection All parts of air conditioner should be finely processed, and the surface of plastic parts should be smooth and uniform in color. The surface of electroplated parts shall be smooth, and there shall be no defects such as peeling, exposed bottom and scratches. There should be no bubbles, flow marks, missing coating, exposed primer layer and uneven surface in the spraying area. All components shall be installed firmly and reliably, and pipes and components shall not rub or collide with each other. Second, the vertical and horizontal air deflector inspection manual vertical and horizontal air deflector should be able to move up and down or left and right, not too tight, not too loose, and should be located in any position and should not be automatically displaced. Third, the filter screen is a part that is often disassembled. Check whether it is convenient to disassemble and assemble and whether it is damaged. Four. Check the function keys and knobs. The knobs on the air conditioning panel should rotate flexibly, fall, not loosen or slide. The function selection buttons on computer-controlled air conditioners, remote controllers and line controllers are flexible and must not be stuck. V. Power-on inspection For integral air conditioners, the following items can be checked when powered on: 1. Refrigeration: in summer, you can try the refrigeration function of air conditioner, turn down the temperature control value, power on for a few minutes, and there should be air conditioning; 2. Heating: If you buy an air conditioner in winter or when the temperature is low, you can try the hot air function; 3, wind speed: adjust the wind speed selection button, there should be different air volume blowing out. Check the noise and vibration of intransitive verbs. When the air conditioner is in refrigeration operation, there should be no abnormal impact sound, excessive vibration and other noises. Seven, electrical performance inspection check whether the power cord and power plug conform to the specifications, pull the power cord should not be loose or pulled out. If possible, you can measure the cold resistance of air conditioner. Eight, accessories, technical documents inspection should check whether the technical documents such as instructions, certificates, warranty cards, packing lists are complete, and check whether the accessories are complete according to the packing list. Finally, don't forget the gift you want before you pay. If you don't have it, in fact, you will definitely give you something after soft grinding and hard foaming, but the specific thing depends on what the promoter has. 6. What services are needed?

The whole machine is guaranteed for one and a half years, and the compressor is guaranteed for three years (now many enterprises have exceeded this requirement: the whole machine is guaranteed for three years and the compressor is guaranteed for five years). 5.24-hour service in place. 6, regular visits, air conditioning maintenance. 7. Professional maintenance team and convenient maintenance points. 7, after delivery to home, not everything is fine! We also need to check the delivered air conditioner. Take a look: when delivering goods to your door, first look at the intact outer packaging, and then the installer will open the carton and take out the air conditioner to install copper pipes. At this time, we are concerned about whether the surface of the air conditioning panel is as smooth as new, without scratches, and whether the air guide page of the air conditioning outlet is complete. If there are obvious scratches or other problems, the installer should be informed in time and specially coordinated to prevent the manufacturer from denying them afterwards. The second choice: See which wall of your house is suitable for hanging air conditioning. The editor also introduced it to everyone before. If it is not a load-bearing wall, users will find fine lines on the wall after installing air conditioners for a period of time, which may not affect the use of anything, but cracks appear in their houses and they feel uncomfortable. Of course, the most important thing is safety. Three impressions: the biggest problem after air conditioning installation is debugging to see if the air conditioner works normally. Generally, heating is checked in winter and cooling in summer. Some friends will ask, can't you heat in summer? The answer is: yes. However, the specific air conditioner should be determined according to the actual situation. This should be asked by the installers of various brands. After the installation, turn on the air conditioner, put your hand on the air outlet or stand under the air conditioner and feel the air coming out of the air conditioner. After starting for a period of time, there has been obvious cold air or hot air blowing out, indicating that the overall operation of the air conditioner is relatively normal. At this time, see whether the noise value of the air conditioner is within the normal use range, and whether there is noise or abnormal sound when starting.
