An electric bus is a bus that runs on pure electricity, usually using batteries to store electricity and an electric motor to power the wheels. Pure electric buses are becoming more and more popular because of their environmental friendliness, lower operating costs, and low noise, and are in line with the trend of the new energy era.

The electric bus air conditioner is an air conditioning system specially designed for electric buses. It also uses electricity as a power source like electric buses. The electric bus air conditioning system uses compressors, evaporators, and fans to reduce the temperature inside the bus. The design of this air conditioning system can minimize the pressure on the bus battery, which can ensure the long-term use of the electric bus and the air conditioning system, and Will not cause damage to the vehicle.
 

How to choose a suitable air conditioner for a pure electric bus?

Choosing the right air conditioner for an electric bus requires consideration of multiple factors, including an air conditioner that can meet the cooling requirements of an electric bus while optimizing energy efficiency, passenger comfort, and overall performance.

Working principle of new energy bus air conditioner

New energy bus air conditioners designed for electric or hybrid buses work similarly to traditional air conditioning systems, but with some modifications to suit the unique characteristics of new energy buses.

Power source: New energy bus air conditioners rely on the power supply provided by the bus battery or hybrid power system. This power is used to drive the components of the air conditioning system.

Electric compressor: Unlike traditional vehicles driven by the engine belt, the compressor in the air conditioner of the new energy bus is driven by electricity. It compresses the refrigerant gas, increasing its temperature and pressure.

Heat exchange: The high-pressure and high-temperature refrigerant gas flows to the condenser for heat exchange. The condenser uses the movement of a fan or bus to dissipate heat, similar to traditional systems. This process converts the refrigerant into a high-pressure liquid.

Expansion Valve: The high-pressure liquid refrigerant then passes through the expansion valve, which reduces the pressure and controls the flow of refrigerant into the evaporator.

Evaporator: Low-pressure liquid refrigerant enters the evaporator, which is usually located in the passenger car compartment. As air from the cabin passes over the evaporator coils, the refrigerant absorbs heat from the air, causing it to evaporate and become a gas. This cools the air inside the bus compartment.

Blower and Air Distribution: A blower or fan circulates the cooled air from the evaporator throughout the coach compartment, ensuring even distribution and passenger comfort. Adjustable vents or diffusers direct airflow as needed.

Refrigerant Cycle: Refrigerant, now in a gaseous state, returns to the compressor to repeat the cycle. It is compressed, cooled in the condenser, expanded in the expansion valve, and evaporated in the evaporator, providing continuous cooling.

New energy bus air conditioners also incorporate other energy efficiencies features, such as variable speed compressors or advanced control systems that optimize cooling performance based on the bus's power availability and passenger load.
 

What kind of compressor is used for electric bus air conditioner?

Electric bus air conditioners typically use electric compressors designed for electric bus applications. These electric compressors were chosen for their ability to efficiently convert electrical energy into mechanical energy, which can drive the refrigeration cycle in air conditioning systems.

There are several common types of electric compressors used in e-bus air conditioners:

Scroll compressor: Scroll compressors are commonly used in electric bus air conditioning systems. They work by using two helical reels that mesh together (one fixed, one orbiting). As the orbiting scroll moves, it compresses the refrigerant gas by trapping it between the spirals. Scroll compressors are known for their quiet operation, high energy efficiency, and reliability.

Rotary compressors: Rotary compressors, such as rotary vane or screw compressors, are also used in electric passenger car air conditioners. These compressors use a rotary mechanism to compress refrigerant gas. Rotary compressors are compact and simple in design for applications where space is limited.

Electric scroll compressors: Some manufacturers have developed electric scroll compressors specifically for electric vehicle air conditioning systems. These compressors combine the advantages of scroll compressors and electric drives to provide efficient and reliable cooling performance for electric buses.

The electric scroll compressor used in the Guche electric passenger car air conditioner makes the electric air conditioner have higher energy efficiency, lower noise, and smaller size. Compressor selection depends on factors such as cooling requirements, space constraints, power supply capabilities, and overall system design.
