When summer arrives, automobile air conditioners will greatly increase fuel consumption and energy consumption. After more than a year of research and testing, Changyun Group successfully recovered the cold energy of LNG, making LNG buses use "free air conditioners" to become a reality. This innovation was awarded the second prize of Changzhou Workers' Science and Technology Innovation Achievements by Changzhou Federation of Trade Unions in 2014.
Natural gas is converted from liquefied storage to combustible gas. This process releases cold energy. The power is about 4 kW, which is equivalent to a 2-4 air conditioner. Using these cold energy to assist the vehicle to cool, not only save energy, And green.
In 2012, the “LNG Energy Recycling Device for LNG Passenger Cars†filed a national patent and was successfully approved in 2013.
However, this technology has not yet been fully promoted. If it is applied to an existing LNG bus, it is necessary to modify the vehicle, so that the safety is not guaranteed. It is best to use it when the bus is manufactured. This is low cost and convenient. Safety.
