Avoid stepping on pits when buying air conditioners, just refer to these points!

Recently, as the temperature rises, some cities in the north have entered a continuous high temperature mode. The continuous high temperature has caused many people to complain: "The air conditioner makes my life a second spring"! In fact, it’s really hard to imagine such a hot weather without air conditioning.

　　 Speaking of air conditioners, many people only care about how to use them, but ignore the purchase of air conditioners. In response to this problem, I will analyze the air conditioner buying guide in detail for you to teach you to avoid stepping on the pit!

　　 1. How to choose fixed frequency and variable frequency?

　　 Fixed frequency air conditioner: The air-conditioning produced per unit time is fixed. When the indoor temperature drops below the set temperature, the air conditioner will automatically stand by; when the temperature rises again, the air conditioner will start again.

　　 Advantages: high cost performance, low failure rate, fast cooling in a short time and large space, but there are also large noises, low temperature control accuracy, disadvantages: high voltage requirements, unable to maintain a constant room temperature

　　 Inverter air conditioner: As the indoor temperature decreases, the working frequency of the air conditioner will be automatically adjusted to slow cooling; when the room temperature rises, it will increase the cooling capacity. The air conditioner will continue to work and keep the room temperature constant by controlling its own cooling capacity.

　　Advantages: low noise, high temperature control accuracy, low voltage requirements, fast temperature adjustment, and maintain a constant room temperature.

　　 Disadvantages: high price and high failure rate.

　　2, cooling capacity

Usually when we buy air conditioners, the most direct idea is to buy cabinet type air conditioners in the living room and wall type air conditioners in the room. In fact, the main difference between cabinet type and wall type is their cooling capacity, and its unit is the familiar “horse". "When the cooling capacity is too small, the predetermined cooling effect cannot be achieved; if the cooling capacity is too large, resources will be wasted. Under normal circumstances, one square meter needs about 170 watts of cooling capacity, applicable area = cooling capacity/170; if the room is facing the sun or the room has a high floor height, one square meter usually needs about 200 watts of cooling capacity, applicable area = cooling capacity/200 . Users can choose air conditioners with different cooling capacities according to their own needs.

　　3, energy efficiency label

　　 Air conditioning energy efficiency is an important parameter to measure the performance of air conditioning. Energy efficiency ratio refers to the ratio of the cooling capacity to the effective input power when the air conditioner is in cooling operation. The larger the value of the energy efficiency ratio, the higher the energy conversion efficiency when the product is used, and the lower the power consumption of the air conditioner product. As long as you see the energy efficiency label on the product, you can make a judgment: Level 1 product is the most energy-efficient, and Level 5 is the most energy-consuming. It is worth noting that energy-saving air conditioners can only be considered as energy-saving air conditioners if they are marked with grades 1 and 2.

　　Air volume problem

　　 For users with larger units, the air volume problem has become an essential reference for users to purchase. When the air volume of the air conditioner is too small and the blowing distance is short, it is often unable to take care of every corner of the room, which directly affects the user experience. The air-conditioning design with large air volume can achieve a larger air supply area by lengthening and widening the air outlet and coordinating with the large circulating air volume, allowing warm air to cover every corner. It seems that users with larger units should refer to the air volume design of the air conditioner when purchasing.

to sum up:

　　 When the fixed frequency air conditioner is stopped and turned on, it is easy to cause a drop in room temperature, and the human body will naturally not feel very comfortable. In terms of temperature experience, inverter air conditioners are more comfortable. If it is for ordinary use, the pursuit of cost performance and stability, and the budget is not high, it is recommended to choose a fixed frequency air conditioner. If you have a high budget and want more comfortable enjoyment, you can buy inverter air conditioners from big brands and good reputation. In addition, the cooling capacity and air volume can be selected according to the user's room size. In terms of energy efficiency labeling, we should choose the air-conditioning product that suits us under the perfect balance of price difference and budget.
