Central air conditioning systems, as the core facility for creating a comfortable environment, play a crucial role in automobiles...The design of the 4S store holds a crucial position. A scientifically rational, energy-efficient, and practical central air conditioning design solution for the 4S store not only provides a comfortable indoor environment for customers and staff but also effectively reduces operating costs and enhances the overall competitiveness of the 4S store.

Here is the automobileDesign proposal for the central air conditioning system in the 4S store and configuration suggestions for the exhibition hall.

System Selection: Depending on the architectural structure and usage requirements of the 4S store, different air conditioning systems can be adopted, such as all-air systems, fan coil unit + fresh air system, and variable-frequency multi-split system, etc. The all-air system is suitable for large exhibition areas, enabling centralized control and adjustment; the fan coil unit + fresh air system is ideal for sales and office areas, allowing independent temperature regulation; the variable-frequency multi-split system is best for areas with inconsistent usage times, offering energy efficiency and flexibility.

2. HVAC Equipment: Select appropriate heating and cooling equipment based on local climate conditions and investment limitations. This includes options such as air-cooled modular hot and cold water units, water-cooled split-type air conditioning units, and split-type water source heat pump units, etc.

3. Ventilation System: To ensure indoor air quality, an independent ventilation system should be set up, which draws fresh air directly from outside, processes it, and then circulates it indoors.

4. Noise Control: The protective structures and flooring of a car showroom typically generate significant noise, so noise control should be a priority in the design of the air conditioning system. This includes selecting low-noise air conditioning equipment, installing sound-absorbing pressure boxes, using flexible connections, and employing vibration-dampening hangers.

Two, AutomobileRecommendations for Central Air Conditioning Display at 4S Shop

Terminal Equipment: Showrooms typically use ceiling-mounted air handlers installed within the walkway ceiling, delivering air through ducts. When the room height is high, it is advisable to use swirl-type air outlets for air distribution; otherwise, double-layer louvered air outlets are sufficient. It is not recommended to use diffusers for air outlets to prevent the phenomenon of upper heat and lower cold in winter.

2. Air Distribution: Utilizing ducted air supply to ensure even distribution and full coverage of the exhibition hall space. Simultaneously, attention must be given to the layout and adjustment of the ducts to avoid excessive use of regulating valves that could affect operation and regulation.

3. Air Conditioning Load Calculation: The cooling load for the exhibition hall's air conditioning is generally 150W/㎡, with a heating load of 120W/㎡. When calculating, consider major factors such as lighting load and personnel load.

4. Fresh Air Volume: The fresh air volume can be set at 80 m³/h·㎡ to meet the requirements for personnel respiration and indoor air quality.

5. Airflow Control: The blowing air speed should be maintained within a reasonable range, generally ≤6m/s, and the return air speed should be ≤3m/s to reduce noise and enhance comfort.

6. Air curtain Installation: It is advisable to set up air curtains at main entrances to prevent outdoor air from directly entering the exhibition hall, affecting indoor temperature and air quality.
