There are 6 tips for choosing a good home use central air conditioning system: 1. Hp; 2. energy efficiency ratio; 3. noise; 4. frequency conversion or fixed frequency; 5. room unit and outlet; 6. brand and service.
1. Know The Hp:
The hp of air conditioners is generally calculated based on the cooling capacity required by the indoor area, which is 150 to 220 watts per square meter, and the cooling capacity of 1 hp is about 2324 watts. In addition, consider the orientation of the house, whether there are large glass windows, etc. If the airtightness of the house is poor, you can choose an air conditioner with a larger horsepower.
2. Check the Energy Efficiency Ratio:
Generally speaking, the larger the energy efficiency ratio, the better. The energy efficiency ratio of household fixed-speed air conditioners is 3.2 to 3.6, which is divided into three levels, and the first level is the best.
3. Compare the Noise:
When the cooling capacity is below 2000W, the noise of the indoor unit cannot exceed 45 decibels, and the noise of the external unit cannot exceed 55 decibels. When the cooling capacity is 2500 to 4500W, the noise of the internal unit cannot exceed 48 decibels, and the noise of the external unit cannot exceed 58 decibels.
4. Need Frequency Conversion or Fixed Frequency?
Central air conditioners can be with variable frequency and fixed frequency, and there is a very obvious difference between them. The advantage of frequency conversion is that there are less starts and stops times, the indoor temperature can be kept stable, and it can be operated in different voltage ranges. The disadvantage is that the price is relatively high, and the failure rate will be higher due to the complex structure. The advantages and disadvantages of fixed frequency air conditioners are opposite to those of frequency conversion.
5. Calculate the Indoor Units and Air Outlets:
One indoor unit or air outlet should be installed in each room or living room. If the living room area is relatively large, an additional indoor unit or multiple air outlets should be added. Calculate according to the method of matching one unit per 12 square meters.
6. Pay Attention to Brand and Service:
The production scale and output of big brands are relatively large, with a complete quality management system, the quality is more guaranteed. In addition, installation service and after-sales service are also the focus of attention. To make the central air-conditioning system operate normally, its design, installation, and construction are also very important. For the success of your project, we work with many well known brands such as Gree, Midea,TCL, etc. And carried many air conditioning project worldwide.
