In this article, we will explain in detail the similarities and differences between electric bus coach air conditioning system and traditional bus AC system. We believe an article can give you a clear understanding. Whether it is an electric bus air conditioner or a traditional bus air conditioner, they are just different types without any obvious difference in class.

Similarities: Bus Coach Air Conditioning System of Electric and Conventional

I. Working Principle (How does air conditioning work in a bus?)

Heat exchange underlying principle: Both types of bus coach air conditioning systems follow the heat exchange principle for cooling. In this process, the evaporator is responsible for absorbing heat inside the bus. It then causes it to be transferred to the refrigerant. While the condenser is responsible for releasing the heat from the refrigerant outside the bus.

In this process, the refrigerant is continuously compressed, condensed, throttled and evaporated through the action of the compressor. When the air conditioner is running, this process will cycle back and forth. The air conditioner is then able to continuously transfer heat from inside the bus to outside the bus. This achieves lower temperatures and increased comfort inside the bus. Both electric and engine-driven compressors play a key role in the air conditioning system.

II. Control System

Temperature adjustment: Both types of bus coach air conditioning systems are equipped with temperature adjustment function. Drivers can adjust the temperature inside the bus through the temperature setting buttons on the control panel to meet different passenger needs.

Wind direction control: Both types of air conditioners provide wind direction adjustment function. Passengers can adjust the direction of airflow according to their personal needs for a more comfortable ride.

III. Maintenance and Repair

To keep the air conditioning system running properly and to prolong its service life, both types of bus air conditioners require regular cleaning and maintenance. This includes cleaning components such as filters, condensers and evaporators. There are also checks on the pressure and purity of the refrigerant, etc.

Differences: Bus Coach Air Conditioning System of Electric and Conventional

I. Power Source (Driving Method)

Electric bus air conditioner system: Its power comes directly from the high-voltage power supply of the electric bus and works through an electric compressor. This design makes full use of the electric power advantage of electric buses. There is no need to rely on the engine to provide power, achieving efficient use of energy.

Conventional bus air conditioning system: Power is usually supplied by a compressor driven by the engine belt. This design is very common in fuel buses. However, it is not applicable to electric buses, which do not have a conventional internal combustion engine.

II. Energy Efficiency and Energy Saving

Electric Bus Air Conditioning System: The electric compressor has a high energy efficiency ratio. It is able to adjust its working condition according to the actual demand. This makes electric bus air-conditioners perform better in terms of energy efficiency and energy saving. This helps to reduce the energy cost of electric buses.

Conventional bus air conditioner system: Its energy efficiency ratio is relatively low. In addition, as it needs to consume part of the engine's power to drive the compressor, it will have some impact on the power performance of the whole bus.

III. Environmental Friendliness

Electric bus air conditioning: no fuel burning is required during operation. It does not produce harmful emissions and causes less pollution to the environment. This is in line with the current global concept of green and low-carbon development.

Traditional bus air conditioning: It also uses environmentally friendly refrigerants. Its air conditioning system itself does not produce emissions directly. However, the engine it relies on produces exhaust emissions during operation. Therefore, it will still cause some pollution to the environment.

Bus Coach Air Conditioning System Summary:

Electric bus coach air conditioning system have many advantages. However, not all buses are suitable for electric bus air conditioning. It is only suitable for fully electric buses because it is powered by a high voltage power source. From the point of view of cooling capacity, there is no essential difference between the two. So there is no need to be anxious. Just choose a reasonable cooling capacity and type of air conditioner according to your bus. The energy efficiency ratio of conventional buses is improving with the upgrading of various parts such as compressors.
