Whether the air conditioner in the room is bigger is better. The arrival of hot summer is also the season of frequent use of air conditioners. Many people have the same misunderstanding when buying room air conditioners, that is, the bigger the room air conditioner, the better. Let's discuss whether the bigger the room air conditioner is, the better.
The bigger the air conditioner, the better. 1 The bigger the better, the room size is the standard. No matter how big the room is, buy an air conditioner with large refrigeration capacity. This is just right, and it will not waste energy. The greater the cooling capacity, the colder it will be indoors for a period of time, which is unbearable for the human body. It consumes a lot of electricity, so it's best to choose the appropriate matching model according to the size of the home. Quding.com
The cooling capacity of air conditioner is calculated by unit area. If you choose an air conditioner with a large cooling capacity, the better the effect will be, but the room itself will not be used so much, and the price of an air conditioner with a large cooling capacity will be higher, which will cause unnecessary waste. Moreover, air conditioners with large refrigeration capacity have large volume and space, high requirements for power supply, and even need to be expanded.
How to choose the size of air conditioner
The more air conditioners you buy, the better. The choice should be based on the size of the living space and the actual living conditions. China's air conditioning and refrigeration units are not the usual figures, but watts. Ceramic tiles are used in other countries in the world, and BTU/H and Kcal/HR are also used in British thermal units.
General selection principles are: refrigeration 150-250W/m2, heating 250-350W/m2. In addition, factors such as space height, horizontal direction, sealing performance and resident population must also be considered. Quding.com
At present, the refrigeration capacity of 1 is about 2500W in the domestic air-conditioning market, which is suitable for10 ~15m2; The refrigeration capacity of 1.5 is 3200-3500W, which is suitable for16 ~ 26 m2; The refrigerating capacity of Erma is 4500-5000W, which is suitable for 20-36㎡.
How to buy an air conditioner to see the cooling capacity and power?
Generally, the cooling capacity is expressed by W. Friends who have studied air conditioning may know horses, but horses do not refer to cooling capacity, but consume electricity. The number of air conditioners mentioned in daily life is the cooling capacity estimated according to the power consumption of air conditioners. The more air conditioners, the greater the cooling capacity.
The cooling capacity of 1 horse ≈2000 kcal, converted into international units × 1. 162, 1 horse should be 2000 kcal× 1.162 = 2324 (w
The bigger the room, the better. Most people don't know much about this common sense. How big the consultation is, refers to the number of people, depending on the size of the space you use. Generally speaking, the refrigeration capacity of an air conditioner is about 2500W, which is suitable for a room of about 12 square meters. The cooling capacity of the two air conditioners is about 5000W, which is suitable for a room of about 25 square meters. 2.5 The cooling capacity of air conditioner is about 6250 W-suitable for a room of about 40 square meters; The cooling capacity of the three air conditioners is about 7500 W-suitable for a room of about 50 square meters; The cooling capacity of four air conditioners is about10000 w-suitable for a room of about 70 square meters. Of course, it will also be affected by the environment, such as the poor sealing and heat preservation conditions of the space, so the refrigeration capacity should be appropriately larger, whereas the refrigeration capacity with good sealing and heat preservation conditions can be smaller. Please refer to the table below for specific area and air conditioning quantity.
The greater the number of air conditioners, the better?
The answer is no, its size selection is also related to the size, sealing, floor, orientation and height of the house, which can generally be calculated according to the cooling capacity per square meter150-220 W.
How to choose air conditioner?
1, select frequency or frequency conversion.
Now technology is changing with each passing day, and products are updated every day. Choosing fixed frequency or variable frequency is a problem that many people will struggle with before. First of all, what is a fixed frequency air conditioner? The grid voltage is 220V and 50Hz, and the air conditioner working under this condition is called fixed frequency air conditioner. Its power supply frequency cannot be changed, and the compressor speed is basically unchanged. By constantly "turning on" and "turning off" the compressor to adjust the indoor temperature, it is easy to cause the room temperature to be hot and cold, and consume more electricity. What is inverter air conditioning? Its main engine automatically performs stepless speed change, can automatically provide the required amount of cold (heat) according to the room situation, can accurately maintain the constant speed operation of this temperature, and realize "non-stop operation", thus ensuring the stability of the ambient temperature. To sum up, of course, it is better to choose inverter air conditioner.
2. Air conditioning energy efficiency rating
Now it is a society that advocates the concept of environmental protection, so actions are also reflected in all aspects of daily life. Choosing energy-saving appliances can also save a lot of electricity for families. At present, all air conditioners sold in China have "China Energy Label", the smaller the better, the more energy-saving. The old energy consumption level is divided into five levels, and the new energy consumption level is three levels. The energy consumption 1 is the best, reaching the international advanced level, and it is the most energy saving, that is, the lowest energy consumption. Just remember that the lower the number, the more energy saving.
3. Brand
Due to the increasing demand, many businesses have poured into this industry, and the sales channels are also varied, including network channels, traditional dealer channels, supermarket channels, chain stores and so on. Choose a good business, and the interests of consumers will be guaranteed twice. In addition, it is really difficult to choose among many brands, but you can refer to the top ten brands in terms of word of mouth, performance, service and quality.
4, the speed of temperature adjustment
From this point, we can determine its performance. The faster the speed, the better the product. On the contrary, the performance is worse. Generally, it is appropriate to keep the room temperature at 25-27℃ in summer and 18-20℃ in winter.
