Technology Highlights

① The intelligent modular platform design realizes the modular combination of compressor unit, electric control system, throttling system, etc., and the design is efficient and reliable.

② Compared with other design platforms, the product has the lightest weight and the smallest roof installation space. It can be installed in the same position on the roof without distinguishing the front and rear installation arrangements.

③ The air outlet of the air conditioner is wider than other platforms, which is suitable for static pressure air ducts and economical air ducts that require wider air outlets of passenger cars;

④ The top cover is formed by blister and has an excellent appearance; the flip cover design is convenient and fast for maintenance.

⑤ The EMC of the product meets the requirements of GB/T 18655 level 3, and the system adopts independent intellectual property rights insulation design, which is safe and reliable;

⑥Adopting adaptive frequency conversion technology, high-end products are equipped with electronic expansion valve, precise control, energy saving and comfortable.

Function Upgrade

In addition to satisfying basic functions such as refrigeration, heat pump heating, and ventilation, the product can also upgrade the following functions according to customer and environmental requirements:

1. Ultra-low temperature heat pump heating function, realizes -15℃ to meet the heat load of the whole vehicle, and -25℃ continuous heat pump operation;

2. Integrated battery thermal management function, under the premise of not affecting the cooling effect of the whole vehicle, the battery cooling capacity of 3-10kw can be output according to customer requirements.

3. Air purification function, including the four major functions of electrostatic dust collection, ultraviolet light, ion generation, and photocatalyst filtration, to achieve sterilization, deodorization and efficient dust removal, and effectively block the path of virus transmission.

4. The “cloud control” function realizes remote control and diagnosis, and improves product service and monitoring capabilities through big data applications.

5. PTC electric heating, according to different configurations and ambient temperature, the PTC can be started at the right time, auxiliary heating, and heating in the full temperature range.
