First, the air conditioning horsepower
Whether you buy hanging air conditioning, cabinet air conditioning, or central air conditioning, the first point of purchase is to look at the air conditioning horsepower. Horsepower represents the size of the cooling capacity, but also related to the cooling effect. How big the air conditioner you want to buy will often be closely related to the area of the environment you want to cool.
From the point of view of use, I personally recommend that within a reasonable range, the number of horsepower to choose a large selection of small, too small, the cooling effect is poor, the experience is weakened, but do not have to be too much to pursue a large number of horsepower, because it will cause a certain amount of waste of energy, and the larger the number of horsepower, often air conditioning prices will be higher.
Generally speaking, the room is between 10-14 square meters, it is recommended to buy a 1 horsepower or a large one horsepower air conditioner. Room size between 15-21 square meters, then it is suitable for 1.5 horsepower air conditioning. 21-31 square meters of the room, it is more suitable to buy 2 horsepower air conditioning, in short, the larger the room, the larger the horsepower.
If the room is on the top floor, or in the west of the room, high family, you can consider buying a little larger horsepower air conditioning, cooling effect will be better.
Second, fixed frequency / frequency conversion
Buy air conditioning to look good is inverter air conditioning or fixed-frequency air conditioning, because there is a certain difference between the two - the compressor does not work in the same way. To control the temperature accurately and more energy efficient, must buy inverter air conditioning (the market is now basically inverter air conditioning).
Inverter air conditioner comparing with fixed frequency air conditioner, an inverter is added, so when it is working, it can control the compressor speed, so as to control the cooling and heating power. When the summer weather is hot, we start the air conditioner, it will run at high power, but when the room temperature is lowered to the set temperature, the power will be automatically reduced, the compressor runs at a low speed, so that the indoor temperature is maintained at a constant state. Compared with fixed-frequency air conditioning using a fixed-frequency compressor, the speed is basically unchanged, relying on frequent switching on and off to control the indoor temperature, inverter air conditioning temperature control is more accurate, comfortable and more energy-efficient.
Of course, some people prefer fixed-frequency air conditioning, because its failure rate is not as high as inverter air conditioning, inverter air conditioning due to its complex structure, and the higher requirements of components, will be more prone to failure.
Third, energy efficiency rating / power consumption
No matter what appliances we buy, we have to consider the issue of power saving. When buying an air conditioner, if we want to focus on power saving, we mainly look at two parameters. One is the APF value, the other is the energy efficiency rating, in fact, the two concepts are equivalent. If you buy online, pay attention to see the product details parameters, offline, pay attention to the air conditioner labeled with a blue “China Energy Efficiency Labeling” expression.
APF value, refers to the annual energy consumption efficiency, the higher the value, the better the air conditioning cooling efficiency, the more energy saving. Good quality air conditioning APF value is generally between 4.2-5, corresponding to the national standard first-class energy consumption. Some big brands of high-end air conditioners, APF value even reached more than 5, beyond the national standard first-class energy consumption standards. In short, if you have the conditions, it is recommended that you buy a first-class energy-efficient air conditioner, energy-efficient value is high, more energy-saving.
Fourth, the noise value
The noise level of an air conditioner can directly affect your sleep quality, so when you buy an air conditioner, it is very important to see what the noise level is. According to the country's new noise law: in ordinary homes, the daytime noise value of 45-70 decibels, the night noise value of 35 decibels -55 decibels for compliance. When choosing an air conditioner, look at the manual or labeling, it will be written.
