The invention discloses a cold and warm box system for an LNG fuel vehicle. The cold and warm box system comprises a cold and warm box shell, a vehicle main gas supply flow path, an LNG cold energy recycling flow path, a refrigerant circulation flow channel, an engine cooling liquid flow path and a cold energy flow path for other purposes. According to the cold and warm box system for the LNG fuel vehicle, under the situation that the engine cooling liquid flow path is not affected, and the additional energy consumption is not needed, the cooling capacity in the LNG gasification process can be recycled to conduct refrigeration, and the quantity of heat of an engine cooling liquid circulation system can be utilized to conduct heating; meanwhile, cold and heat switching and optimal temperature control under two kinds of modes are achieved at the same time, and thus the requirements for refrigeration in summer and heating in summer of a driver are met.
