How to calculate the number of central air conditioners
When choosing a central air conditioner, the number of horsepower is a very important parameter, which is directly related to the cooling or heating effect of the air conditioner. So, how to calculate the number of central air conditioners? This article will give you a detailed answer and attach structured data to help you understand better.
1. What is the number of central air conditioners?
Horsepower (HP) is the unit of air conditioning cooling capacity. One HP is approximately equal to 2500W of cooling capacity. The number of horses of a central air conditioner is usually used to indicate its cooling or heating capacity. The larger the number of horses, the stronger the cooling or heating capacity.
2. How to calculate the number of central air conditioners?
Calculating the number of central air-conditioning units requires comprehensive consideration of room area, floor height, orientation, thermal insulation performance and other factors. The following are common calculation methods:
| 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 |
3. Factors affecting the selection of match numbers
In addition to the room area, the following factors will also affect the choice of the number of central air conditioners:
1.Floor height: When the floor height exceeds 3 meters, it is recommended to increase the number of pieces appropriately.
2.towards: West-facing or south-facing rooms require greater cooling capacity.
3.Insulation performance: Rooms with poor thermal insulation performance require larger air conditioners.
4.Personnel density: A densely populated room requires increased cooling capacity.
4. The relationship between the number of central air conditioners and energy efficiency ratio
Energy efficiency ratio (EER) is an important indicator to measure the energy consumption of air conditioners. The larger the number of units, the higher the energy efficiency ratio is usually. The following is the corresponding relationship between common number of horses and energy efficiency ratio:
| Number of pieces | Energy Efficiency Ratio (EER) | Annual power consumption (kWh) |
|---|---|---|
| 1 horse | 3.2-3.5 | 800-1000 |
| 1.5 horses | 3.5-3.8 | 1000-1200 |
| 2 horses | 3.8-4.0 | 1200-1500 |
| 3 horses | 4.0-4.2 | 1500-1800 |
5. How to choose the appropriate number of central air conditioners?
1.Measure room area: Accurately measure the length, width and height of the room.
2.Consider special factors: If it is exposed to western sun, poor thermal insulation performance, etc., increase the number of pieces appropriately.
3.Consult a professional: It is recommended to contact the air conditioner sales or installer for more accurate suggestions.
6. Summary
The number of central air conditioners is an important parameter when selecting an air conditioner. It needs to be calculated comprehensively based on room area, floor height, orientation and other factors. Choosing the right number of horses not only ensures comfort, but also saves energy. I hope this article can help you better understand the calculation method of central air conditioning horsepower.
