莫斯科的“氦机器”科研生产联合公司生产了一种“低温气体”自动冷冻车,采用液氮作制冷剂,底盘是“ΓA3—3307”汽车。该冷冻车用于运输新鲜的冷却或速冻了的易腐食品。由于使用对环境无污染的制冷系统,建立了无氧环境,所以,可降低食品在运输中的损失。所定温度可依靠在绝热车内喷液氮来自动保持,绝热车由低导热率的材料制成。 Moscow’s “Helium Machine” research production joint company produced a “cryogenic gas” automatic freezing car, the use of liquid nitrogen as refrigerant, the chassis is “ΓA3-3307” car. The freezer is used to transport fresh, frozen or frozen perishable food. Due to the use of an environmentally friendly refrigeration system, an oxygen-free environment is established so that the loss of food in transit can be reduced. The set temperature can be automatically maintained by spraying liquid nitrogen in an insulated car, made of a material with a low thermal conductivity.
