Detailed Technical Introduction of the SZQ Series Bus Air Conditioner

1. Beautiful Appearance

SZQ series air conditioner adopts thin design, the thickness of the air conditioner is 188mm, which is lower than the thickness of the current conventional air conditioner, which meets the requirements of the bus for the height control of the air conditioner. In addition, the appearance of the air conditioner is designed to be streamlined, which is in line with modern aesthetics and has a beautiful and fashionable appearance.

2. Lightweight design

The condenser uses a parallel flow core. The condenser base is designed as an inverted V-shaped frame without bottom shell structure. The evaporator assembly air duct adopts an innovative bottom shell integrated bending structure. Through the above methods, the weight of the air conditioner is greatly reduced.

3. Efficient heat transfer

In the design of the flow path of the parallel flow condenser, the high temperature area of the internal refrigerant corresponds to the area of the condenser’s frontal wind speed. The heat resistance of the high temperature difference and the reasonable design of the process length are used to reduce the flow resistance. thereby increasing the heat of the condenser and exchange ability so as to maximize the efficiency of parallel flow heat exchangers.

4. Environmental protection

Compared with traditional tube-fin condensers, the SZQ series uses optimized parallel flow cores and optimization of air conditioning system piping. These helps to reduce the refrigerant charge by 40%. Thereby reducing the impact of refrigerant leakage on the environment.

The SZQ Series Bus AC Functions Upgrade (Optional)

1. Defroster and Air conditioning in Driver’s cabin

The defroster, and AC in driver’s cabin can be installed according to customer’s requirement, to provide a comfortable environment for the driver.

2. Integrated central control technology

The integration of the control panel and the vehicle instrumentation is convenient for the centralized layout of vehicle control. The remote control function of product control is added to facilitate customer operation management.

3. Plumbing and heating technology

The water heating pipe can be led out from the core of the evaporator to realize the heating function of the air conditioner and meet the requirements of the ambient temperature in the bus in the cold area.

4. Air purification technology

It includes mainly four functions: electrostatic dust collection, ultraviolet light, strong ion generator, and photocatalyst filtration, which can achieve full-time, uninterrupted anti-virus and sterilization, odor removal and efficient dust removal, effectively blocking the virus transmission path.

5. Remote control diagnosis technology

“Cloud control” function, realize remote control and diagnosis, and improve product service and monitoring capabilities through big data application.

6. Energy Regulation Technology

According to the temperature in the bus and the environment, the flow of the fan and compressor is adjusted in multiple stages to reduce the frequent start and stop of the compressor, improve the overall comfort of the passengers, and ensure that the system operates more efficiently.

The Application of the SZR Series Bus AC:

With the development of the market and the improvement of living standards, bus has gradually increased from traditional simple means of transportation to paying more attention to the improvement of comfort and transportation environment. Therefore, high-end passengers have been increasing year by year in recent years. SZR focuses on the appearance and is suitable for high- and mid-range buses. The market outlook is good.

1. The wide range of application

The bottom arc of the SZR series is suitable for roof arcs with a radius of 6~72 meters, the unit width is 1860mm, and the air outlet is directly fed into the air ducts on both sides of the bus, which is easy to install. The product series has 8 models from small to large, and the cooling capacity is 20~ 40KW, suitable for 8~13 meters buses.

5. Energy Regulation Technology

According to the temperature in the bus and the environment, the flow of the fan and compressor is adjusted in multiple stages to reduce the frequent start and stop of the compressor, improve the overall comfort of the passengers, and ensure that the system operates more efficiently.

2. Rich configuration Options

The SZR series is rich in configurations for different user groups, and there are multiple configurations for users to choose.

High-end configuration: mainly for the import configuration of public transport and high-end tourist buses, fans and other accessories

Economic configuration: It is mainly aimed at the configuration of economic buses, tourist buses, fans and other accessories.
