PURPOSE: A delivery vehicle has small freezer and refrigerator installed inside the container thereof to deliver chilled food as well as normal product. CONSTITUTION: The vehicle has installed small freezer and refrigerator customized to occupy 3-10% of space of the container thereof considering wiring and moving line of cargo. Every delivery vehicle can deliver frozen and chilled food as well as normal product to deliver product rapidly with inexpensive cost comparing with the usual method needing separate chill cars to deliver chilled food. As the vehicle has the freezer and the refrigerator separately, the frozen food and the chilled food can be stored separately to maintain freshness.
