How to calculate the number of central air conditioners
The number of horses of a central air conditioner is an important parameter to measure its cooling capacity. Choosing the appropriate number of horses can not only ensure comfort, but also save energy. This article will introduce in detail how to calculate the number of central air conditioners, and attach structured data for reference.
1. Definition of number of central air conditioners

The "number of horses" of a central 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 is suitable for larger rooms.
2. How to calculate the number of central air conditioners
The following factors need to be considered when calculating the number of central air conditioners:
1.Room area: Room area is a key factor in determining the number of pieces. Generally speaking, 150-200W cooling capacity is required per square meter.
2.room orientation: Rooms facing south or west require greater cooling capacity.
3.room height: Rooms with a floor height of more than 3 meters need to increase the number of tiles appropriately.
4.Thermal insulation properties: Rooms with poor insulation also require greater cooling capacity.
3. Recommended number of central air conditioners
| Room area (㎡) | Recommended number of matches | Refrigeration capacity (W) |
|---|---|---|
| 10-15 | 1 horse | 2500 |
| 15-20 | 1.5 horses | 3500 |
| 20-30 | 2 horses | 5000 |
| 30-40 | 3 horses | 7500 |
| 40-50 | 4 horses | 10000 |
| 50-60 | 5 horses | 12500 |
4. Other influencing factors
In addition to the room area, the following factors will also affect the choice of the number of central air conditioners:
1.Number of residents: The more people there are, the greater the cooling capacity required.
2.Electrical appliance heats up: If there are many heating appliances (such as computers, TVs, etc.) in the room, the number of units needs to be increased appropriately.
3.Regional climate: Hot areas require greater cooling capacity.
5. Central air conditioning unit calculation formula
The number of central air conditioners can be calculated by the following formula:
Required cooling capacity (W) = room area (㎡) × cooling capacity per square meter (150-200W) × correction factor
The correction coefficient is adjusted according to factors such as room orientation, height, thermal insulation performance, etc., and is generally 1.0-1.5.
6. Hot Topics and Hot Content
Among the hot topics on the Internet recently, discussions about central air conditioning mainly focus on energy saving, intelligent control and number selection. The following is the hot content in the past 10 days:
| hot topics | focus of discussion |
|---|---|
| Central air conditioning energy saving tips | How to reduce energy consumption through horse number selection and rational use |
| Intelligent central air conditioning | Intelligent control and automatic adjustment technology of number of pieces |
| Central air conditioning installation misunderstandings | The impact of too large or too small number of pieces on the use effect |
7. Summary
Choosing the right number of central air conditioners is the key to ensuring comfort and energy saving. The right number of tiles can be easily determined by calculating the room area, considering other influencing factors, and referring to the recommended table. Recent hot topics also remind us that a reasonable selection of the number of chips can not only improve the user experience, but also reduce energy consumption.
