How is an insulated (isothermal) vehicle classified when it uses a source of cold other than a mechanical or absorption unit to lower and maintain the temperature inside the body?

Question

DentroTest · Accepted Answer

According to the classification by construction criteria in Annex II of the General Vehicle Regulations, the refrigerated vehicle is an insulated vehicle that, with the aid of a source of cold other than a mechanical or absorption unit, makes it possible to lower the temperature inside the body and maintain it. The insulated vehicle on its own is not enough: it is the vehicle whose body has insulating walls (with doors, floor and roof) to limit the exchange of heat with the outside, but that does not mean it has a source of cold. The mechanically refrigerated vehicle, on the other hand, carries a cold-producing device, such as a mechanical compression unit or an absorption machine, which keeps the temperature permanently at set values.
