PROBLEM TO BE SOLVED: To provide a cooling system for a nap capable of efficiently cooling the inside of the nap room 13 over a driver's cabin without narrowing the inside of the driver's cabin 12. SOLUTION: A cooling unit 15 for supplying cooled air is installed in the nap room 13. Focusing attention on a fact that a top sleeper vehicle has a nap room 13 on the ceiling of the driver's cabin 12, the cooling unit 15 for cooling the nap room 13 is also installed in the nap room 13. Specifically, it is installed under a bed for a nap or the like installed in the nap room 13. Thus, it does not narrow the inside of the driver's cabin 12. A circulation in a small space of taking air from the nap room 13, cooling it, and blowing it into the nap room 13 is allowed, so that the inside of the nap room 13 can be efficiently cooled. A blow off duct for guiding cold air to the nap room 13 is not required, so that air pressure loss becomes small and the cost can be suppressed. COPYRIGHT: (C)2005,JPO&NCIPI
