Chinese companies are stepping up their research and development efforts on refrigeration equipment for exhaust gas (mainly refrigerated trucks and fishing boats).

 

Exhaust gas ice making and refrigeration technology collects exhaust gas from car and ship engines and uses heat for energy conversion without any additional fuel, and can be cooled to minus 30 degrees Celsius.

 

As a major fishing and logistics country, China has a large number of fishing boats and refrigerated trucks. Fishing boats going out to sea are generally equipped with more than 1,000 tons of ice to ensure the freshness of the fish caught. After being equipped with this exhaust gas refrigeration unit, fishing boats can achieve continuous operation at sea without returning to the port for ice addition; refrigerated logistics vehicles can achieve passive refrigeration, while also increasing the income of fishermen and car owners. This technology is also applicable to new energy vehicles and ships such as electricity and hydrogen. In the future, it can also use the waste heat from the chimneys of large thermal power plants and other enterprises to collect and build large cold storages. Compared with traditional fishing boats returning to the port for ice addition and refrigerated trucks, this technology not only reduces operating costs but also significantly reduces energy consumption and environmental pollution, and the power consumption is only about 5% of traditional compressors.

 

This technology has currently produced a prototype vehicle. If it goes well, it will have broad commercial prospects in China and even the world.
