Recreational Vehicle Air Conditioner is suitable for many vehicle types, including vans, minibuses, mid-sized buses, and RV. This is a cost-effective option chosen based on actual needs. If you find bus air conditioners too expensive,

various cooling capacities (e.g., 13,500 BTU, 15,000 BTU) are available on the market, theoretically matching the large space of a mid-sized bus.
RV air conditioners are designed for mass-produced RVs with pre-designed installation locations, reinforced roof structures, and planned air ducts. Mid-sized buses, being passenger vehicles, do not have roof structures or electrical layouts designed for this purpose.
Therefore, as long as a professional modification shop reinforces, drills, and seals the roof, vehicles with flat roofs, such as minibuses and mid-sized buses, can be equipped with it.
Of course, if some countries require cargo loading on the roof, then this rooftop RV AC is not suitable.

Recreational Vehicle Air Conditioner

Why use a Recreational Vehicle Air Conditioner instead of a bus air conditioner specifically for mid-sized buses? The latter (referring to a type of air conditioning system) is more expensive, while the former (referring to a type of air conditioning system) is cheaper. Although the cooling capacity isn’t as high, it’s enough to keep the interior from becoming like a sauna.

“RV air conditioning” can be understood as a system (including various solutions optimized for RV living, such as roof-mounted, floor-mounted, and split systems), while “roof-mounted air conditioning for buses” specifically refers to high-power, high-airflow, and highly reliable roof-mounted air conditioning systems designed for large passenger vehicles.

While a bus air conditioner specifically designed for minibuses can lower the interior temperature within 10 minutes, it consumes a lot of electricity and has a large airflow. Upgrading the electrical system would require several times the cost.

A recreational vehicle air conditioner, while cooling more slowly and not reaching a very cool state, at least ensures a relatively comfortable environment for the driver and passengers, preventing excessive sweating. It also prevents driver fatigue caused by heat, thus ensuring vehicle safety.

In a closed metal vehicle cabin, after direct sunlight, the interior temperature can rise above 50°C within 15 minutes, and the humidity often exceeds 80%. This “steam room” environment can rapidly raise the body’s core temperature, leading to heat exhaustion, heatstroke, and multiple organ failure, posing a fatal risk. The elderly, children, and those with weakened immune systems are particularly at risk.

Many people might think, “Can’t I just open the windows for ventilation instead of installing air conditioning?”

Answer: In Southeast Asian climates, this is extremely ineffective and introduces new problems.

When the outside temperature reaches 35°C and the humidity is 80%, opening the windows only allows hot air to circulate inside the vehicle, failing to lower the temperature. Hot air blows in while driving, and there is no wind at all when parked.

Even on a tight budget, air conditioning (and its matching electrical system) must be among the highest priorities in your modification budget. You can choose a cost-effective option based on your specific needs.
