Ac For Skoolie requires comprehensive consideration of factors such as cooling capacity, energy efficiency ratio, noise control, compatibility, and brand reliability.
Here are specific selection points and suggestions:
1. Focus on key performance indicators
Cooling capacity: School buses have large spaces, requiring a high-capacity Ac For Skoolie to ensure rapid cooling. For example, the rated cooling capacity of the passenger compartment air conditioning unit should be 29kW, 37kW, 40kW, or 44kW. Energy Efficiency Ratio (EER): Air conditioners with a high EER are more energy-efficient. It is recommended to choose products that meet national energy efficiency standards (such as air conditioning units using R407C or R410A refrigerants, with an EER of no less than level 2). Noise Control: The noise level of the air conditioning unit should not exceed 75dB(A) to ensure a quiet environment inside the vehicle. Airflow and Uniformity: A large airflow can make the temperature distribution inside the vehicle more uniform. Multiple air outlet modes and airflow direction adjustment should be supported.
2. Compatible Vehicle Models and Installation Methods
Split Unit vs. Integrated Unit Selection: School buses are generally suitable for installing roof-mounted integrated units (hidden design, saving space) or split units (indoor and outdoor units separated, flexible layout). The appropriate Ac For Skoolie must be selected based on the school bus’s structure.
Component Matching: Compressors, filters, condensers, and other components must be fully compatible with the school bus brand and model, ensuring that dimensions and performance meet requirements.
3. Functional and Comfort Requirements
Zoning Control: If the school bus requires zoning (e.g., driver’s cab and passenger area), a system supporting independent temperature control can be selected.
Air Purification: Prioritize air conditioners equipped with high-efficiency filters to ensure student health.
Intelligent Inverter Technology: Inverter air conditioners automatically adjust cooling capacity according to temperature, saving energy and operating smoothly, suitable for school buses used for extended periods.
4. Testing and Maintenance
Trial Run Testing: After installation, noise, cooling effect, and airflow uniformity must be tested.
Daily Maintenance: Regularly clean the condenser, replace the filter, and avoid turning off the Ac For Skoolie directly when the bus is parked to extend its service life.

The cooling capacity of Ac For Skoolie is typically calculated using the following formula:
Cooling Capacity (kW) = Interior Space Volume (m³) × Air Change Rate × Indoor/Outdoor Temperature Difference × Air Specific Heat Capacity ÷ 3600
Interior Space Volume: The product of the length, width, and height of the school bus interior.
Air Change Rate: Generally 0.5-2 times/hour, depending on the vehicle’s sealing performance.
Indoor/Outdoor Temperature Difference: The difference between the target temperature inside the vehicle and the ambient temperature (unit: °C).
Air Specific Heat Capacity: Approximately 1.005 kJ/(kg·K)
Special Adjustments for Skoolie Air Conditioning
Due to frequent starts and stops, door opening and closing, and passenger movement, school buses require adjustments to the basic formula:
1. Passenger Cooling Factor: Adjusted based on the number of passengers.
For example:
16-30 passengers: 600 W/person
31-37 passengers: 575 W/person
And so on. The more passengers, the lower the required cooling capacity per unit.
2. Climatic Condition Factor:
Cold regions: Multiply by 0.94
Hot/Humid regions: Multiply by 1.04
Sealing and Insulation Factor: Adjusted based on the vehicle’s insulation performance (e.g., 1.0 for good sealing, 1.2 for poor sealing).
The cooling capacity of Ac For Skoolie can be expressed as:
Q = (A₁×N + A₂×V + A₃×S) × A₄ × A₅
A₁: Occupant cooling factor (refer to table)
N: Number of passengers
A₂: Interior space cooling factor (e.g., 553 W/m³ for vehicles over 6m)
V: Interior space volume
A₃: Solar thermal radiation factor (e.g., 1190 W/m² for vehicles over 6m)
S: Total window glass area
A₄: Sealing and insulation factor
A₅: Climatic condition factor
