How to check the number of duct machines
With the arrival of high temperatures in summer, duct machines, as a type of central air conditioner, have attracted more and more attention from consumers. When choosing a duct fan, the number of horses is a very important parameter, which is directly related to the cooling or heating effect. So, what is the number of horses for the air duct machine? This article will give you detailed answers.
1. What is the number of duct machines?
Horsepower (HP) is the unit of air conditioning cooling capacity. One HP is approximately equal to 2500W of cooling capacity. The number of duct fans is usually used to indicate its cooling or heating capacity. The larger the number of horses, the stronger the cooling or heating capacity, and the larger the suitable area.
2. How to calculate the number of duct machines?
The number of duct fans can be calculated based on the cooling capacity. The following is the common correspondence between the number of horses and cooling capacity:
| Number of horses (HP) | Refrigeration capacity (W) | Applicable area (㎡) |
|---|---|---|
| 1 horse | 2500 | 10-15 |
| 1.5 horses | 3500 | 15-25 |
| 2 horses | 5000 | 25-35 |
| 3 horses | 7200 | 35-50 |
| 5 horses | 12000 | 50-70 |
3. How to choose the number of air duct machines according to the room area?
When selecting the number of duct machines, factors such as the area, floor height, orientation, and thermal insulation performance of the room need to be considered comprehensively. Here is a simple reference table:
| Room area (㎡) | Recommended number of horses (HP) |
|---|---|
| 10-15 | 1 horse |
| 15-25 | 1.5 horses |
| 25-35 | 2 horses |
| 35-50 | 3 horses |

1.Floor height: Rooms with higher floors require larger numbers of air duct machines.
2.towards: Rooms with west or south exposure have greater cooling requirements.
3.Insulation performance: Rooms with poor thermal insulation performance require a larger number of air duct machines.
4.Number of users: In densely populated rooms, cooling needs are greater.
5. How to check the number of duct machines?
1.View product nameplate: The number of horses or cooling capacity is usually marked on the nameplate of the air duct machine.
2.View product manual: The manual will list the technical parameters of the product in detail, including the number of pieces.
3.Consult sales staff: You can ask the sales staff directly when purchasing.
6. Things to note when choosing the number of duct machines
1.Don’t blindly pursue a large number of horses: Excessive number of horses not only wastes energy, but may also affect comfort.
2.Consider frequency conversion technology: The variable frequency air duct machine can adjust the power according to actual needs and is more energy-saving.
3.comprehensive assessment: In addition to the number of horses, factors such as energy efficiency ratio, noise, brand, etc. must also be considered.
7. Recommended brands and numbers of popular air duct machines
The following are some popular duct machine brands on the market and their recommended number of units:
| brand | Recommended models | Number of horses (HP) | Applicable area (㎡) |
|---|---|---|---|
| Gree | GMV-H120WL | 5 horses | 50-70 |
| Beautiful | MDVH-V80W/N1-310 | 3 horses | 35-50 |
| Haier | RFC100MXSA | 5 horses | 50-70 |
| Daikin | VRVIV | 3 horses | 35-50 |
8. Summary
When selecting the number of duct machines, factors such as room area, floor height, and orientation need to be considered comprehensively.
