How to classify central air conditioners
As an indispensable facility in modern buildings, central air conditioning is classified in various ways, mainly based on working principles, usage scenarios and functional characteristics. The following is a detailed classification and feature analysis of central air conditioners to help users better understand and choose a suitable central air conditioner system.
1. Classification according to working principle
| Type | Working principle | Applicable scenarios |
|---|---|---|
| Water system central air conditioning | Cold and heat are transferred through water circulation, and the main unit is separated from the terminal. | Large commercial buildings, hotels, hospitals |
| Fluorine system central air conditioning | Heat absorption through direct evaporation of the refrigerant, high efficiency | Small and medium-sized residential and office buildings |
| Wind system central air conditioning | Directly transfers cold and heat through air, simple structure | Industrial plants and warehouses |
2. Classification by usage scenarios
| Type | Features | Typical applications |
|---|---|---|
| Household central air conditioner | Energy saving, silent, beautiful and concealed | Villas, apartments |
| Commercial central air conditioner | High power and strong stability | shopping malls, office buildings |
| Industrial central air conditioning | Resistant to high temperature and humidity, anti-corrosion | Workshop, laboratory |
3. Classification according to functional characteristics
| Type | Functional advantages | technical representative |
|---|---|---|
| Inverter central air conditioner | Energy saving of more than 30%, precise temperature control | DC frequency conversion technology |
| Intelligent central air conditioning | Remote control, adaptive adjustment | Internet of things technology |
| Fresh air central air conditioning | Air purification, humidity adjustment | Full heat exchange technology |
4. Precautions when purchasing
1.Energy efficiency ratio: Choose first-class energy-efficiency products to save energy during long-term use.
2.Noise value: For home use, it is recommended to choose products below 40 decibels.
3.Maintenance cost: The water system requires regular pipe cleaning, and the fluorine system is easier to maintain.
4.Installation conditions: It is not recommended to install ceiling-mounted central air conditioners in houses with a floor height of less than 2.6 meters.
5. Industry development trends
1.Intelligent: In 2023, 60% of new central air conditioners will be equipped with APP control functions.
2.Environmental protection: The proportion of R32 refrigerant used increased to 45%.
3.Integration: Integrated design solutions with floor heating and fresh air systems increased by 35%.
It can be seen from the above classification comparison that the selection of central air conditioners needs to comprehensively consider factors such as building type, usage requirements, and budget. It is recommended that consumers consult professional HVAC engineers for personalized plan design when purchasing.
