摘要： PROBLEM TO BE SOLVED: To prevent discharge pressure and a discharge temperature of a compressor from increasing when air capacity of an external heat exchanger becomes small in vehicular stop. SOLUTION: As a temperature of a refrigerant circulating in a refrigerating cycle comprising a compressor 1, a heat-exchanger 2 outside a cabin, a restriction device 3, a heat-exchanger 4 inside the cabin, the discharge temperature of the compressor is detected by a temperature sensor 5. When stopping the vehicle, if the discharge temperature of the compressor becomes higher than a first set value, the number of revolutions of a fan 6 outside the cabin is increased, and if the discharge temperature of the compressor becomes even higher than a second set value, the number of revolutions of an electric motor for driving a compressor 1 is decreased by means of instructions from a compressor control apparatus 18.

摘要： PROBLEM TO BE SOLVED: To provide an on-vehicle rotary compressor for allowing high-speed rotation.
SOLUTION: The compressor 112 is constituted so that a front rotary piston 30a and a rear rotary piston 30b, and a front roller 32 and a rear roller 33 which are disposed on the outer periphery receive a rotation force from a crankshaft 31 via a front side needle bearing 34 and a rear side needle bearing 35, and thus the front roller 32 and the rear roller 33 eccentrically rotate with respect to a front cylinder 21 and a rear cylinder 22. The compressor 112 can reduce a mechanical loss between the outer peripheral surface of the front roller 32 and the inner peripheral surface of the front cylinder 21, and a mechanical loss between the outer peripheral surface of the outer peripheral surface of the rear roller 33 and the inner peripheral surface of the rear cylinder 22, and can improve the compression efficiency by the high-speed rotation.

摘要： PROBLEM TO BE SOLVED: To provide a thermal storage type vehicular air conditioner keeping interior temperature during traveling constant, efficiently storing cold, and using the cold as an auxiliary cooling device for suppressing a temperature rise in the vehicular interior during idling. SOLUTION: An evaporator and a thermal accumulator are connected in series as a coolant flow path, and a vehicular interior is successively air- conditioned during traveling, thereby suppressing rising/lowering of vehicular temperature. Excessive cold obtained by deducting a vehicular interior load from cooling performance generated by successively operating an air conditioner is stored. During idling, the cold is dissipated to use for an auxiliary cooling device, thereby suppressing a temperature rise in the vehicular interior. COPYRIGHT: (C)2003,JPO
