How to choose the number of air conditioners
With the arrival of high temperatures in summer, air conditioners have become an essential appliance for many families. However, in the face of a dazzling array of air-conditioning products on the market, how to choose the appropriate number of units has become the focus of consumers' attention. This article will provide a detailed analysis of the definition, selection method, applicable area, etc. of air conditioners, and provide structured data to help you easily choose a suitable air conditioner.
1. Definition of number of air conditioners
The "number of horses" of an air conditioner refers to its cooling capacity. One horse is approximately equal to 2500W of cooling capacity. The larger the number of horses, the stronger the cooling capacity and the larger the suitable area. The following is the common correspondence between the number of air conditioners and cooling capacity:
| Number of pieces | Refrigeration capacity (W) | Applicable area (㎡) |
|---|---|---|
| 1 horse | 2500 | 10-15 |
| 1.5 horses | 3500 | 15-20 |
| 2 horses | 5000 | 20-30 |
| 3 horses | 7200 | 30-50 |
| 5 horses | 12000 | 50-80 |
2. How to choose the number of pieces according to the room area
The core basis for choosing the number of air conditioners is the room area. Generally speaking, 150-200W cooling capacity is required per square meter. The following are the recommended numbers for rooms of different sizes:
| Room area (㎡) | Recommended number of matches |
|---|---|
| 10-15 | 1 horse |
| 15-20 | 1.5 horses |
| 20-30 | 2 horses |
| 30-50 | 3 horses |
| 50-80 | 5 horses |
3. Other influencing factors
In addition to the room area, the following factors will also affect the choice of the number of air conditioners:
1.room orientation: For rooms facing south or west where direct sunlight lasts a long time, it is recommended to choose an air conditioner with a slightly larger number of units.
2.Floor height: Rooms with a floor height of more than 3 meters have greater cooling needs, and the number of units needs to be increased appropriately.
3.room usage: In areas such as kitchens and living rooms where people are densely populated or where there are many heating devices, it is recommended to choose a larger number of units.
4.Regional climate: In areas with high temperature and humidity in the south, it is recommended to choose an air conditioner with a larger number of units.
4. The relationship between the number of air conditioners and energy efficiency ratio
Energy efficiency ratio (EER) is an important indicator to measure the energy consumption of air conditioners. The higher the value, the more energy it saves. When choosing the number of horses, you also need to pay attention to the energy efficiency rating. The following is the relationship between common energy efficiency levels and number of watts:
| Energy efficiency level | 1 horse | 1.5 horses | 2 horses |
|---|---|---|---|
| Level 1 energy efficiency | 3.6 or above | 3.5 or above | 3.4 or above |
| Level 2 energy efficiency | 3.4-3.6 | 3.3-3.5 | 3.2-3.4 |
| Level 3 energy efficiency | 3.2-3.4 | 3.1-3.3 | 3.0-3.2 |
5. Summary
Choosing the appropriate number of air conditioners can not only meet the cooling needs, but also save electricity bills. It is recommended to comprehensively consider factors such as room area, orientation, floor height, etc., and give priority to high-energy-efficiency products. I hope the structured data in this article can help you make informed purchasing decisions!
