How to determine the number of central air conditioners?
When purchasing a central air conditioner, choosing the appropriate number of units is the key to ensuring cooling or heating effects. The number of horses is directly related to the power and applicable area of the air conditioner. Choosing the wrong one may lead to excessive energy consumption or poor performance. This article will introduce in detail how to choose the appropriate number of central air conditioners according to your needs, and provide structured data for reference.
1. What is the number of central air conditioners?
The number of horses is a unit to measure the cooling capacity of the air conditioner. One horse is approximately equal to the cooling capacity of 2500W. The number of central air conditioners is usually determined based on room area, floor height, orientation and other factors. The larger the number of horses, the stronger the cooling or heating capacity, but the energy consumption will also increase accordingly.
2. How to choose the number of pieces according to the area?
The following is a table of correspondence between common room areas and number of tiles:
| Room area (㎡) | Recommended number of matches | Applicable scenarios |
|---|---|---|
| 10-15 | 1 horse | Small bedroom, study room |
| 15-25 | 1.5 horses | Master bedroom, living room |
| 25-35 | 2 horses | Large living room and conference room |
| 35-50 | 3 horses | Villa living room, large office |
| 50 and above | 4 horses and above | Commercial places, large spaces |
3. Other factors affecting the selection of match numbers
In addition to area, the following factors will also affect the choice of number of tiles:
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 need to add 0.5-1 pieces.
3.Insulation performance: Rooms with poor thermal insulation need to choose a larger number of units.
4.Number of users: Rooms with many people or electrical appliances need to increase the number of units.
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 electricity consumption (estimated) |
|---|---|---|
| 1 horse | 3.2-3.5 | 800-1000 degrees |
| 1.5 horses | 3.5-3.8 | 1000-1200 degrees |
| 2 horses | 3.8-4.0 | 1200-1500 degrees |
| 3 horses | 4.0-4.2 | 1500-1800 degrees |
5. How to calculate the actual number of pieces needed?
The number of matches required can be roughly calculated using the following formula:
Cooling capacity (W) = room area (㎡) × cooling capacity required per square meter (W/㎡)
The required cooling capacity per square meter is usually 150-200W, which is adjusted according to the above factors. For example, a 20㎡ room:
20㎡ × 180W/㎡ = 3600W ≈ 1.5 hp
6. Summary
Choosing the appropriate number of central air conditioners requires comprehensive consideration of factors such as area, floor height, orientation, etc. If the number of horses is too small, the cooling effect will be poor, and if it is too large, energy will be wasted. It is recommended to consult a professional before purchasing and make a choice based on actual needs.
Through the reference of the above data and methods, you can choose the appropriate number of central air conditioners more scientifically, which can not only meet the usage needs, but also save energy costs.
