How about installing central air conditioning? Comprehensive analysis of advantages, disadvantages and purchasing guide
In recent years, with the improvement of the quality of life, central air conditioning has become the first choice for decoration in many homes and commercial places. This article combines hot topics and data from the entire Internet in the past 10 days to analyze the advantages and disadvantages of central air conditioners from multiple dimensions such as installation cost, usage experience, and maintenance costs, and provides purchase suggestions.
1. Comparison of the advantages and disadvantages of central air conditioning
| Advantages | Disadvantages |
|---|---|
| Uniform cooling/heating, comfortable | Initial installation costs are higher |
| Save space (hidden installation) | Need to be constructed simultaneously with decoration |
| Lower energy consumption (frequency conversion technology) | Maintenance is complex and requires a professional team |
| Long life (15-20 years) | Cleaning and maintenance costs are higher |
2. Popular brands and price references (latest data in 2024)
| Brand | Series | Applicable area (㎡) | Reference price (yuan) |
|---|---|---|---|
| Daikin | VRV series | 80-120 | 35,000-50,000 |
| Gree | GMV Zhirui | 60-100 | 25,000-40,000 |
| Beautiful | Ideal Home III | 90-150 | 28,000-45,000 |
3. The five major issues consumers are most concerned about
1.Power consumption:Central air conditioners are not "electric tigers". One-to-four models consume about 15-20 degrees of electricity per day in summer (with the help of frequency conversion technology).
2.Installation restrictions:The floor height must be ≥ 2.6 meters, and more than 1.5 square meters of space should be reserved for outdoor units. The feasibility of pipelines must be assessed for renovation of old buildings.
3.Cleaning and maintenance:It is recommended to professionally clean it once a year (the cost is about 300-500 yuan/unit) and replace the filter by yourself once a month.
4.Troubleshooting:Common problems are refrigerant leakage (repair fee 800-2,000 yuan) and circuit board damage (replacement fee 1,500+).
5.Value for money:It is suitable for families with ≥3 rooms and a large number of permanent residents. For small houses, it is recommended to consider the combination of duct fan + split air conditioner.
4. Suggestions on purchasing
1.Look at energy efficiency:First-class energy efficiency models with APF energy efficiency ratio ≥5.0 are preferred, as they have significant long-term power saving effects.
2.Than service:Focus on the coverage density of brand after-sales outlets. Mainstream brands usually provide 6-10 year warranty.
3.Calculate the load:The cooling capacity per square meter needs to be ≥200W, and it is recommended to increase the capacity by 20% for west-facing rooms.
4.Test noise:The operating sound of the indoor unit should be ≤35 decibels (equivalent to a library environment).
5. New technology trends in 2024
1.Photovoltaic linkage:Some brands have launched solar auxiliary power supply systems, increasing the energy saving rate by 30%.
2.AI temperature control:Automatically adjust the air supply angle and temperature through human body induction.
3.Self-Cleaning 4.0:Combination of condensate frost dust removal + 56℃ high temperature sterilization technology.
In summary, central air conditioning has obvious advantages in comfort and aesthetics, but it is more suitable for scenarios with sufficient budget and long-term living. It is recommended that consumers make choices based on the structure of the house and actual needs, combined with professional designers' plans.
