KINGCLIMA- Articulated Bus Air Conditioning Product Introduction

Introduction

KINGCLIMA’s centralized air conditioning system is a professional climate control solution exclusively developed for 18-25 meter articulated buses and coaches. Unlike conventional bus air conditioners, this product focuses on solving the core technical challenge of ensuring stable air duct connection and efficient air supply at the vehicle’s articulation point—even when the bus is turning sharply, passing through bumpy roads, or operating under extreme environmental conditions. With innovative technological designs, it achieves a perfect balance of comfort, reliability, energy efficiency and compatibility, providing passengers with a stable and comfortable riding environment while reducing operational costs for bus operators. It is an ideal choice for modern articulated public transport vehicles pursuing high performance and low energy consumption.

1. Product Definition

This centralized air conditioning system is specifically designed for 18-25 meter articulated buses/coaches, which are widely used in urban public transport, intercity passenger transport and other scenarios due to their large passenger capacity. The most prominent feature and core challenge of this type of air conditioning system lies in the articulation point of the articulated bus—a flexible connection part that allows the vehicle to turn flexibly. When the bus turns, tilts or encounters bumps on the road, the articulation point will generate a certain range of rotation and displacement, which easily leads to air duct leakage, deformation or poor air supply. Therefore, the key technology of KINGCLIMA’s articulated bus air conditioning lies in ensuring reliable connection and efficient air delivery at the articulation point under any operating conditions, while meeting the overall climate control needs of the long-body bus.

2. Core Advantages and Technological Innovations

• Flexible Joint-Type Air Duct

To solve the problem of air duct damage and air leakage at the articulation point, KINGCLIMA adopts a specially designed flexible joint-type air duct. It uses high-quality special composite material corrugated pipes that possess excellent flexibility, corrosion resistance and wear resistance, and is equipped with universal rotary joints with high precision. This design ensures that the air duct can freely adapt to the rotation and displacement of the articulation point when the vehicle is turning or bumping, without any leakage or deformation. At the same time, the composite material also has good thermal insulation performance, which can reduce cold and heat loss in the air duct, further improving the energy efficiency of the air conditioning system and ensuring stable air supply to every corner of the bus.

• Multi-Zone Independent Intelligent Control

Considering the long body of articulated buses and the different temperature needs of passengers in different areas, the product is equipped with a multi-zone independent intelligent control system, which is divided into two key functions to meet diverse comfort needs.
◦ Independent Temperature Control for Front and Rear Passenger Compartments: The system divides the bus into three independent control zones: driver’s area, front passenger compartment and rear passenger compartment. Each zone can set and maintain different target temperatures according to actual needs. For example, the driver’s area can be set to a more comfortable temperature to ensure the driver’s concentration, while the front and rear passenger compartments can be adjusted according to the number of passengers and ambient temperature, avoiding the problem of uneven temperature in the long-body bus and improving the overall riding comfort.
◦ On-Demand Adjustment: The air conditioning system is equipped with high-sensitivity passenger density sensors installed in different compartments. These sensors can real-time detect the number of passengers in each zone and transmit the data to the intelligent control system. The system then automatically adjusts the fresh air volume and cooling capacity according to the passenger density—reducing air supply and cooling capacity when there are few passengers, and increasing them when there are many passengers. This on-demand adjustment mode not only ensures the comfort of passengers but also achieves energy savings of up to 20%-30%, effectively reducing the operating costs of bus companies.

• Superior Environmental Adaptability

Articulated buses often operate in various harsh environmental conditions, so KINGCLIMA’s air conditioning system is designed with superior environmental adaptability, covering both high-temperature cooling and low-temperature heating needs.
◦ Cooling: The system is equipped with a high-efficiency compressor and optimized heat exchange structure, which can quickly cool down the interior of the bus even in extreme high temperatures above 45℃. It only takes a short time to reduce the interior temperature to a comfortable range, ensuring that passengers can enjoy a cool environment even in hot summer.
◦ Heating: To adapt to frigid regions, the system integrates two heating modes: high-efficiency electric auxiliary heating and engine waste heat utilization. In extremely cold conditions down to -30℃, the electric auxiliary heating can quickly start to provide warm air, while the engine waste heat utilization mode can fully reuse the waste heat generated by the vehicle engine, reducing energy consumption while meeting the heating needs. This dual heating mode ensures the normal start and stable operation of the air conditioning system in low-temperature environments, avoiding the problem of insufficient heating in cold weather.

• Low Energy Consumption and Compatibility

In response to the development trend of new energy vehicles, the product pays special attention to low energy consumption and compatibility with electric buses, while improving passenger comfort through quiet operation design.
◦ Electric Bus Optimization: For electric articulated buses, the air conditioning system can intelligently collaborate with the vehicle’s BMS (Battery Management System). It real-time monitors the battery’s power, temperature and other parameters, and dynamically adjusts the air conditioning’s energy consumption according to the battery’s operating status—avoiding excessive energy consumption of the air conditioning affecting the vehicle’s driving range. This intelligent collaboration achieves optimal energy efficiency, effectively extending the driving range of electric articulated buses and solving the pain point of high energy consumption of air conditioning in electric buses.
◦ Quiet Operation: The system adopts an optimized fan and duct design, selecting low-noise fans with high air volume and low power consumption, and optimizing the internal structure of the air duct to reduce air resistance and noise generated during air supply. The low-noise design ensures that the air conditioning system operates quietly, avoiding noise interference to passengers and the driver, and further enhancing the riding comfort of the bus.
