3. More convenient installation and maintenance: Installing the air conditioning on the roof is easy to lay and fix pipes. In addition, the roof position is also easier to access when performing maintenance or repairs.
A complete bus air conditioning system is composed of multiple parts. The bus aircon parts include a compressor, electromagnetic clutch, condenser, liquid reservoir, filter dryer, solenoid valve, expansion valve, evaporator, and fan.
I'll go into detail on each parts individually. The combination of their functions is the working principle of bus aircon.
bus air conditioning system diagram
Function: Inhale refrigerant in gaseous form and then compress it. The compression process will increase the temperature and pressure of the refrigerant and turn it into a high-pressure and high-temperature gas form.
Function: Receive electrical signals from the bus aircon control system to control the start and stop of the compressor.
Function: Heat exchanges the high-temperature and high-pressure gaseous refrigerant discharged from the compressor with the surrounding environment (usually air or water), and releases heat to the environment. After the heat exchange, the refrigerant cools down and condenses into a liquid state.
Function: Store liquid refrigerant. It is used to compensate for changes in refrigerant flow caused by changes in operating conditions in the air conditioning system. Changes in operating conditions such as start-up, storage and cooling phases after thawing.
Function: Remove moisture and impurities from refrigerant. Effectively prevent them from causing damage to various components and extend their service life.
Function: Control the flow of refrigerant in the air conditioning system. Specifically, it can interrupt or allow refrigerant flow to the evaporator by closing or opening it.
Function: It automatically adjusts the flow of refrigerant into the evaporator according to the temperature and pressure of the refrigerant at the evaporator outlet. It ensures that the refrigerant in the evaporator can fully evaporate.
Function: Liquid refrigerant evaporates in the evaporator. The heat required for evaporation comes from the surrounding air. This allows the air to be cooled before entering the bus.
Evaporator Fan Function: Inhales the cooled air from the evaporator and blows it into the interior of the bus to provide a cool environment for passengers.
Condenser Fan Function: Heat dissipation. When the gaseous refrigerant passes through the condenser, it emits a large amount of heat. The high-speed rotation of the fan introduces air for cooling. Eventually the refrigerant changes from gas to liquid.
Our bus aircon refrigerants use R134A and R407C. They are widely used environmentally friendly refrigerants. They are environmentally friendly, non-toxic and have good cooling effect.
Bus air conditioning is mainly divided into two categories. They are electric bus aircon and traditional fuel bus aircon. They are suitable for different aircon bus due to their different power sources.
Electric bus aircon can only be installed on pure electric buses. This type of aircon requires a very high voltage to operate. Usually between 280v-750v. Such voltage requirements can only be met by the power batteries of pure electric buses. But this kind of aircon bus is very environmentally friendly and energy-saving, and the noise is relatively low. The ride experience brought to passengers is very good. New aircon buses like TATA Motors all use aircon like this. Click to browse project cooperation stories.
Traditional fuel bus air conditioner is installed on diesel buses. This type of aircon has wider applicability. There is no need to consider the voltage range. Just choose the appropriate cooling capacity according to the length of the bus. Then connect the bus's engine and bus aircon compressor through a belt. When the aircon needs to be operated, the bus engine can drive the aircon to work. The cooling capacity of this aircon is also very good. The riding experience on fuel aircon bus is also very good now.

' Bus air conditioning system compressor
The compressor is one of the most important parts of the bus air conditioning system. Its function is to compress and transport refrigerant vapor. It is the power device that drives the refrigerant to circulate continuously in the refrigeration system.
There are three main common types, centrifugal compressor, screw compressor, and scroll compressor. Among them, the scroll compressor is now the latest type of compressor. It has a higher compression ratio, higher system efficiency, and has a small size, low noise, and other characteristics. General high-grade bus air conditioning systems are used in this type of compressor.
The world's most famous brands include Germany BOCK, Japan SANYO, Germany BITZER and so on. These brands of compressors in terms of performance and quality are more guaranteed. If you have enough budget, it is recommended to recognize these big brands when picking a bus air conditioner.
Compressor Function Principle
1, The compressor draws in low-temperature and low-pressure refrigerant and increases its temperature and pressure by compression.
2, The compressor transports the high-temperature and high-pressure refrigerant to the condenser. The refrigerant exchanges heat with the outside air, emitting heat and lowering the temperature of the refrigerant.
3, The cooled refrigerant is transported to the evaporator, where it exchanges heat with the air inside the bus and absorbs heat from the air. The heat in the air is absorbed to achieve the cooling effect.
' Electromagnetic clutch for bus air conditioning system
It belongs to the commander in the bus air conditioning. It is responsible for controlling the start and stop of the compressor. Its working principle is the electromagnetic induction phenomenon.
When the air conditioning system needs to work, the air conditioning control module sends out an energizing command, which generates electromagnetic force to make the compressor and engine work together. When the opposite situation occurs, the power is disconnected and the electromagnet will lose its electromagnetic force, thus separating the compressor from the engine.
' Bus air conditioning system condenser
The condenser is one of the important components in the air conditioning system. It is responsible for transferring the heat of the refrigerant to the outside air so that the high-temperature and high-pressure gaseous refrigerant is transformed into high-temperature and high-pressure liquid refrigerant.
In simple terms, it mainly accomplishes the heat dissipation process.
' Bus air conditioning system evaporator
The evaporator is another important component in the air conditioning system. Its role is to evaporate the liquid refrigerant in the evaporator through heat exchange with the refrigerant and absorb the heat in the air, thus realizing the cooling and dehumidification inside the bus.
In simple terms, it mainly accomplishes the process of cooling the air inside the bus.
' Bus air conditioning system filter drier
Filter drier is an indispensable part of the air conditioning system. It plays a vital role in ensuring the normal operation and prolonging the service life of the air conditioning system.
Its function is to remove water and impurities in the refrigerant. It can effectively prevent the blockage of pipes and components and ensure the normal operation of the refrigeration system.
' Refrigerants for bus air conditioning system
The liquid and gaseous forms of refrigerant were mentioned repeatedly earlier. It is an important factor in heat exchange. Therefore, its selection has a significant impact on the performance and efficiency of the air conditioning system.
The most common refrigerants for bus air conditioning systems are R-134A, R-407C, and R-22. R-22 is now being phased out. This is mainly because it is more damaging to the environment.
When you purchase a bus air conditioner, please make sure to choose R-134A or R-407C. It is everyone's responsibility to take care of the environment. Protecting the environment is protecting human beings.
To summarize, a bus air conditioning system operates through a number of components working together. The core principle is mainly the heat exchange effect brought about by the compression, condensation, evaporation and expansion of refrigerant.
