How to choose a bus air conditioner?

What is Bus AC?

Bus AC stands for bus air conditioner. It specifically refers to the air conditioning system used in buses. Its presence is very important for safe driving and the comfort of the passengers.

The main components of a bus air conditioner are compressor, condenser, expansion valve, evaporator, condensing fan, evaporating fan, and control system, etc.

Which AC is used in bus?

Which type of air conditioning a bus uses depends largely on the type of bus. If it is a traditional fuel bus, then it can only use a traditional bus AC. If it is a new electric bus, it will need to install an electric bus AC. This is because the two types of air conditioners are driven differently and therefore there is no way they can be used indiscriminately.

How to choose the right bus AC?

&#; The first step is very simple.

The type of bus air conditioner needs to be judged in relation to the type of bus. Choose a conventional air conditioner for conventional buses and an electric air conditioner for electric buses.

&#; The second step is to choose the cooling capacity of the bus AC.

It needs to be determined based on the size of the bus and the expected number of passengers. Regular buses can directly choose the corresponding model based on the length mentioned in the title of TKT bus AC.

For example, "13M-14M Diesel Big Bus Air Conditioner", which corresponds to your bus being fuel driven and between 13-14m in length. Usually a 13-14m bus needs 38-40kw of cooling capacity. a 8-10m bus needs around 20-26kw. a 6-7m bus needs around 15-18kw.

Conventional Diesel Bus Air Conditioning

Then again, "10M-12M Electric Bus Air Conditioning", it corresponds to your bus being purely electric powered and between 10-12m in length. Usually a 10-12m bus needs a cooling capacity of around 35-42kw. an 8-10m bus will need around 20-26kw of cooling capacity. 6-7m buses are usually around 10-16kw.

Electric buses have different components than conventional buses. Even if the length of the bus is the same, the actual passenger space of the bus is different. Therefore the cooling capacity required for air conditioning is also different. TKT HVAC has extensive OEM experience in providing customized bus AC services. Inquiries are welcome.

Electric Bus Air Conditioning

In addition to the length of the bus, the cooling capacity is also related to your local temperatures. If your local temperature is not very high and there is a cost reduction consideration, you can also choose a lower air conditioning model. Of course, if you have enough budget, I suggest you should choose the corresponding length. Because now the global temperature continues to rise, if you find that the cooling capacity is not enough, and then replace a new air conditioner, the cost is very big.

&#; The third step is to identify the core component configurations used by the bus air conditioner supplier - the determining factor of bus AC quality.

A bus AC is a complex air conditioning system. It is made up of a series of parts such as the compressor, condenser, and evaporator. Damage to any one of the parts will cause the system to fail to operate.

Among them, the quality of the core and vulnerable parts usually determines the stability and service life of the bus air conditioner. If you are greedy for the low price of purchase, you are likely to get endless after-sale problems and insufficient cooling capacity in return.

The compressor is one of the important parts of the bus AC.

First of all, the type please make sure to recognize the scroll compressor. This is the most advanced type of compressor nowadays.

Secondly, please make sure to recognize the big brands, such as BOCK, BITZER, SANYO, and so on. They are world-famous brands with the best performance and stability. As a 24-year bus AC expert, I remind you that this part is not to be saved.

A high quality bus air conditioning compressor is very important.

The evaporator and condenser are important parts in determining heat transfer efficiency.

If they are of average quality, they may lead to problems such as reduced heat exchange efficiency, increased energy consumption, and decreased system stability.

Let's say you are a person with a large meal. The meal is very flavorful, but you are only given a very small, very small spoon. If you now have only 10 minutes to eat, you will not be able to finish all the food even if you try harder.

Please be sure to choose the copper tube and aluminum sheet type for the evaporator and condenser cores rather than the parallel flow.

Parallel flow core is made of aluminum, which is cheaper and lighter, and can save cost. But compared to the copper tube aluminum sheet type, it is in the most important heat transfer efficiency, corrosion resistance and comprehensive life, the gap between the two is very large.

Condenser cores and evaporator cores are very important.

If you still want to know more details about the configuration, please leave your contact information and talk to TKT HVAC engineers.

&#; The fourth step: Bus AC Warranty

A bus air conditioner price is affected by the cost of its individual parts and the cost of labor. Aside from that, it also has a lot to do with how long it takes to file a warranty and what it covers. The top bus air conditioner manufacturers usually have a warranty period of 18 months. For special projects, they are generally willing to accept requests to extend the warranty for an additional fee.

Any product and part has its own lifespan. If it meets the customer who can use it, the life span will be longer. If it meets the customer who will not use it or uses the environment poorly, then the life span will be shorter. The same is true for bus air conditioners. Are you willing to be a customer who will use it or a customer who won't use it?

Therefore, when purchase a bus AC, on the one hand you need to choose a bus air conditioner manufacturer that emphasizes on product quality. On the other hand you need to learn how to properly use and maintain your bus air conditioner.

How do I maintain my bus air conditioner?

When summer comes, the bus AC will keep running at a high frequency for a long time. In order to use it better, it is very important to take good care of it. That way it won't drop the ball at critical moments. Here are some of the most common maintenance requirements. Be sure to schedule your employees to complete them.

1, Condenser and evaporator cleaning
Check and clean the air path to ensure it is clear. It is recommended to clean them 2-3 times a year.

2, Return to the cleaning of the grille
Wash with water and dry completely. Clear 1-2 times per month is recommended.

3, Confirmation of refrigerant condition
Regularly observe whether the refrigerant quantity in the system is sufficient through the liquid-viewing mirror. If the sight glass is transparent without bubbles, the refrigerant is normal; if there are bubbles, it means that the refrigerant is insufficient, and it is necessary to look for the leakage parts and replenish the refrigerant.

4, Inspection of each joint
Regularly check whether each joint of the gas line and pipeline is firm. If found even deal with it to avoid refrigerant leakage. Recommended 2-3 times a year.

How bus ac works&#;

The working principle of a bus AC is similar in nature to that of a home air conditioner. They are both based on the properties of refrigerants.

First, bus air conditioners evaporate into a gas by means of a refrigerant that absorbs heat from the inside of the bus in an evaporator. The heat inside the vehicle is absorbed and therefore cooling is achieved.

In the second step, the refrigerant quickly removes heat through the action of the condenser and condensing fan. After the heat is removed it changes back to a liquid state. This allows it to continue to absorb heat from the car inside the evaporator.

In the third step, the continuous flow of refrigerant is not something that can be accomplished spontaneously. It requires the impetus of a compressor. The compressor is the key to continuous circulation, thus ensuring continuous cooling.

The cycle is completed by multiple parts running at the same time, and is not really sequential. I'm just explaining it for ease. I have a more detailed article on this, if you don't understand it yet click on it. https://www.busthermo.com/bus-aircon-news/

In addition to similar principles, other places are very different.

1, scale size: the size, cooling capacity and weight of bus air conditioners are much larger than home air conditioners.

2, Functionality: the bus air conditioner is used in a more complex environment. It needs stronger shock resistance, corrosion resistance, high temperature resistance, etc..

3, maintenance: bus air conditioning frequency of use, power and passenger capacity is usually higher, so regular maintenance and maintenance is very important.

In summary, the price of bus air conditioning is much higher than home air conditioning. After all, one is a commercial product, one is a residential product. The difference in performance and quality is huge.

Summary of bus air conditioners

The focus of choosing a bus AC is the cooling capacity and product quality and after-sales service. It is normal for a bus air conditioner to be more expensive if you have high requirements for the three key elements. If you have a limited budget or choose a supplier with an extremely low quote, then you have to accept that one or even two of these points are not excellent.

It is a universal truth that you get what you pay for. For example, Samsung cell phones are believed to be a familiar brand of cell phones. It mainly consists of high-end models in the Galaxy S and Note series, as well as low-end and mid-range models in the Galaxy A and M series. The different models all address basic call functions, running of commonly used apps, and other functions. They are all of one brand, so why do they still have different prices? Obviously because they have different part configurations. High-end models choose top processors, lens modules, screen materials, etc., which correspondingly improve the performance, camera, and screen experience.

After knowing so much, what quality of bus AC do you want to choose?

This article introduces in detail the components of bus aircon and the working principles of each part. I try to make the content of the article easy to understand. I believe you will gain a lot from reading this article carefully.

Why is the bus aircon system installed on the roof mounted?

There are three main benefits of the roof mounted bus air conditioning system.

1. Higher space utilization: Installing the air conditioning on the roof can make full use of the external space of the bus. In this way, the bus can carry more passengers, more seats, and a better experience.

2. Better heat dissipation: Installing the air conditioning on the roof of the bus can make full use of air convection. Improve the heat dissipation effect and ensure the efficiency and stability of the air conditioning system.

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.

What are bus aircon parts?

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.

Parts details - How does a bus aircon system work?

&#; Bus Air Conditioning Compressor

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.

Bock traditional compressor SANYO electric compressor

&#; Bus AC Electromagnetic Clutch

Function: Receive electrical signals from the bus aircon control system to control the start and stop of the compressor.

&#; Bus Air Conditioning Condenser

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.

&#; Bus AC Reservoir

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.

&#; Bus AC Filter Drier

Function: Remove moisture and impurities from refrigerant. Effectively prevent them from causing damage to various components and extend their service life.

&#; Bus AC Electromagnetic Valve

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.

&#; Bus AC Expansion Valve

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.

&#; Bus Aircon Evaporator

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.

&#; Bus Aircon Fan

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.

What are the different types of bus air conditioning?

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.
