TKT is BYD-Olectra bus air conditioning supplier

Bus air conditioning is mainly divided into two types, one is electric bus air conditioner and the other is diesel bus air conditioner. Air conditioner for electric bus is only suitable for pure electric bus and is powered by power batteries. This type of air conditioner requires a very high voltage, generally between 280-750v. Air conditioner for diesel bus is suitable for traditional diesel bus and is mainly driven by the engine. This type of air conditioner will not be able to operate the air conditioner when the bus is stopped. Of course, TKT has sub engine bus air conditioner to solve this problem and ensure that the diesel buses have uninterrupted air conditioning when parked. TKT supports OEM/ODM services.

+ Bus Air Conditioner Basics

What is Bus Air Conditioner?

Bus air conditioner is an air conditioning system used in bus. It provides a comfortable travelling environment for passengers by regulating air temperature, humidity and flow rate. A bus air-conditioning system consists of major components such as compressor, condenser, evaporator, expansion valve and fan. The compressor is responsible for compressing the refrigerant and raising its temperature and pressure; the condenser dissipates the high temperature and pressure refrigerant through the radiator, cooling it and condensing it into a high-pressure liquid; the expansion valve controls the flow rate and pressure of the refrigerant so that it enters the evaporator; and the fan is used to circulate the air and increase the air flow rate.

How does a bus air conditioner work?

The operation process of the bus air conditioner system is as follows: the compressor draws in the low-temperature and low-pressure refrigerant gas and converts it into a high-temperature and high-pressure gas through compression; subsequently, the high-temperature and high-pressure gas passes through the condenser to dissipate the heat, and condenses into a high-pressure liquid through cooling; the high-pressure liquid then enters into the evaporator through the expansion valve, and the low-pressure liquid in the evaporator flows through the pipeline, and the contact with the outside air occurs with heat transfer, and the refrigerant absorbs heat and evaporates into a gas, making the internal temperature of the evaporator rise. The refrigerant absorbs heat and evaporates into gas, which lowers the temperature inside the evaporator, thus achieving the cooling effect.

Which models are bus air conditioning suitable for?

Bus air conditioning is applicable to a wide range of vehicle types, and the need to install an air-conditioning system is mainly determined by their usage, passenger carrying capacity and operating environment.

City Buses: As the main mode of public transport in cities, city buses usually need to carry a large number of passengers. Installing air-conditioning systems in these vehicles can ensure that passengers can enjoy a comfortable travelling environment even in the hot summer months.

Long-distance buses: Long-distance buses are often required to travel on motorways or inter-regional routes, where passengers need to spend long periods of time in the vehicle. Therefore, it is necessary to install air-conditioning systems for long-distance buses.

Tourist buses: Tourist buses are mainly used for sightseeing tours and usually carry tourists on long journeys. Installing high quality air conditioning systems in these vehicles can enhance the travelling experience.

Double-decker buses: Due to their special design and large passenger capacity, double-decker buses require an air-conditioning system that can evenly distribute cool air and provide a comfortable environment.

In general, bus air conditioning systems are suitable for models that need to carry a large number of passengers and run for long hours. These systems can be customised and optimised to meet the specific needs of different models to ensure passenger comfort and satisfaction.

What type of refrigerant is typically used in bus air conditioner?

The refrigerant used in bus air conditioner, R-134A, is one of the most common and widely used refrigerants.
R-134A is now internationally recognised as the main refrigerant workhorse replacing R-12, and is used not only in bus air conditioning but also in a wide range of commercial and industrial refrigeration systems.
R-407C is the refrigerant of choice for air conditioning in electric bus. In addition, refrigerants such as R-22 and R-410A may be used in some specific applications or in bus air conditioning system of specific manufacturers.

How do I maintain and service my bus air conditioner?

1. Check the air-conditioning pipework and connecting parts: After prolonged use, the air-conditioning pipework and connecting parts may become loose or cracked, resulting in poor cooling effect. Therefore, it is necessary to check the status of these parts regularly.

2. Check refrigerant pressure: Refrigerant is the core component of the air conditioning cooling process. Use a refrigerant pressure checking tool to check the refrigerant pressure and determine if the pressure is normal based on the standard values provided by the manufacturer.

3. Clean the evaporator and condenser: the cleanliness of these components directly affects the cooling effect. The surfaces of the evaporator and condenser should be cleaned regularly to ensure that they dissipate heat well.

4. Check the compressor and fan: regularly check the quality of the compressor and fan. They will affect the refrigeration effect.
