The goods must maintain a certain temperature, humidity and ventilation in the process of transport, so the insulated car body is equipped with thermal insulation material, and the refrigerated van is equipped with a cooling device, heating device, temperature measuring device, and ventilation. The refrigerated van has three functions: refrigeration, heat preservation and heat.
