Product Introduction

The DFDD air conditioning independent unit is a complete air conditioning system driven by a dedicated auxiliary engine. The primary advantage of this system is its strong and stable cooling effect. Whether the vehicle is in motion, idling, or parked, it can consistently maintain a comfortable temperature without drawing power from the main engine. This feature makes it ideally suited for the high-load operational requirements of large and medium-sized buses, as well as long-distance coaches. It can be used with any model of air conditioner.

CLING DFDD Bus Independent Unit Air Conditioner

Stable and unaffected

The air conditioning compressor operates independently; driving, parking, and air conditioning do not influence one another, ensuring optimal vehicle performance and cooling output. It excels in environmental protection, low noise, low fuel consumption, low emissions, and high torque.

No loss of main engine power

The air conditioning system operates independently from the main engine, which means it doesn't draw power from the engine. This design prevents issues like weak acceleration and difficulty climbing when the air conditioner is on. Additionally, the air conditioner can be used while the bus is stopped without consuming extra fuel. It is especially suitable for buses and long-distance coaches that start and stop frequently or require high-power cooling.

Working principle

The auxiliary engine drives the compressor to work, compressing the gaseous refrigerant into high-temperature and high-pressure gas. After being cooled and liquefied by the condenser, the gas is throttled through the expansion valve, absorbs heat and evaporates in the evaporator, and is finally converted to cold air and sent into the car through the fan.
