DC Air Conditioner for Bus

The DC Air Conditioner for Bus has evolved from an auxiliary component enhancing comfort to a core system directly impacting vehicle range, operating costs, and emissions reduction effectiveness.

According to an industry report released by QYResearch in October 2025, the electric bus air conditioning market is experiencing rapid growth driven by the technological upgrades guided by the 15th Five-Year Plan.

Meanwhile, a joint notice issued by the National Development and Reform Commission and the Ministry of Finance in December 2025 clearly states that continued support will be provided for the upgrading of new energy urban buses, offering strong policy and financial guarantees for the advancement of vehicle technology, including high-efficiency air conditioning.

DC Air Conditioner For Bus

Input Voltage – The DC Air Conditioner for Bus

Adopts a wide DC input voltage range, covering 12V, 24V, and the mainstream DC 280V-750V. Some products can even be customized from DC 200V to 900V, or adapted to multiple platforms such as DC 12V to 720V, to flexibly match the power batteries of different vehicle models.

Cooling/Heating Capacity – DC Air Conditioner for Bus

Rated cooling capacity ranges from 10kW to over 40kW, meeting the needs of various bus models from 6 meters to 18 meters. Heating relies on efficient heat pump technology or PTC auxiliary electric heating.

Cooling Performance Ratio (COP) and Energy Saving – DC Air Conditioner for Bus

Utilizing a DC inverter compressor, the cooling energy efficiency ratio (COP) can reach over 3.4, saving 20% more energy than traditional electric air conditioners. Research by the International Council on Clean Transportation (ICCT) indicates that optimizing air conditioning energy efficiency is key to reducing greenhouse gas emissions from bus fleets.

DC electric air conditioning for buses is a technology-intensive and high-value system. Its development is rapidly evolving towards “higher energy efficiency, intelligent integration, and environmentally friendly cooling,” becoming one of the indicators of a country’s electric bus technology level and commitment to green transformation.
