With the growing awareness of environmental protection, many owners of traditional fuel-powered buses are seeking quiet, low-emission cooling solutions without significantly modifying the bus's electrical system. TKT has proposed a "parallel 24V bus air conditioning" solution, which is ideal for small traditional buses. The retrofit solution: By connecting multiple 24V parking air conditioners in parallel, the overall cooling capacity is increased while avoiding the need to upgrade to a 400V+ high-voltage system, significantly reducing the difficulty and cost of the retrofit.
Technically, to power multiple 24V air conditioners simultaneously, the battery capacity must be increased and sufficient current output must be ensured. This approach allows for independent power supply when parked and allows the existing bus AC generator to charge the battery while driving, eliminating the need to use the vehicle's starting battery. We are open to inquiries regarding battery expansion, but we highly recommend consulting the battery manufacturer you intend to purchase from, as they offer greater expertise in this area.
This solution offers significant advantages: ① Cost optimization—lower procurement and retrofit costs compared to 400V high-voltage electric bus air conditioning systems; ② Convenient retrofit—no complex high-voltage wiring or extensive air duct modifications are required. ③ Easy maintenance—A single unit failure does not disable the entire vehicle, making replacement easy. ④ Higher safety—The 24V system eliminates the risk of electric shock from high voltage.
Cool your minibus with the TKT 24V low-voltage bus air conditioner—compact, energy-efficient, and environmentally friendly. Its quiet operation, low retrofit costs, and quick turnaround time make it a new upgrade option for traditional minibus fleets.
