摘要： PROBLEM TO BE SOLVED: To effectively perform the cooling storage by recovering power in decelerating a vehicle.
SOLUTION: A storage medium of a cooling storage unit is cooled and solidified by cold air passing through an evaporator for cooling the air to be sent into a cabin. The operation of a compressor is intermittently controlled to adjust a temperature of the evaporator to a target temperature (S210). When the cool storage of the storage medium is not completed, the target temperature of the evaporator is determined to an initial cooling storage target temperature lower than a solidifying temperature of the storage medium (S240, S250), when the cooling storage of the storage medium is completed, and the vehicle is not in a decelerating state, the target temperature of the evaporator in determined to the temperature higher than the initial cooling storage target temperature and lower than the solidifying temperature, and when the vehicle is in the decelerating state, the target temperature of the evaporator is determined to a temperature lower than the cooling storage retaining target temperature.

摘要： PROBLEM TO BE SOLVED: To provide an air conditioning device for a vehicle rear seat to approximately equalize the temperature of air blown off toward feet at a seat with that of air blown off toward a head part at a seat and to provide an air- conditioning device for a vehicle rear seat to decrease the temperature of air blown off toward a head at a seat to a value lower than that of air blown off to feet at a seat by a given temperature. SOLUTION: A hot water flow rate for the heater core 42 for a total pass type is regulated by a flow rate regulating valve 6. An opening part 44 for foot blowoff and an opening part 43 for face blowoff are arranged adjoining to each other longitudinally and vertically of a tube 423a in a spot situated downstream of a flow of air of a heater core 42. Thus, air throughout a total temperature range, corresponding from the inlet side to the outlet side of the tube 423a, flows to each of the opening parts 43 and 44 for blowoff. Further, cold air through a cold air passage bypassing the heater core 42 is mixed in the opening part 43 for face blowoff.

摘要： PROBLEM TO BE SOLVED: To perform an efficient heating by providing a heating element for heating a cooling water passing a water passage in this water passage on the upstream side of cooling water flow of a heat storage tank. SOLUTION: The cooling water flowing out from an engine 3a is carried into a heat storage tank 9 to push the cooling water in the heat storage tank 9 toward a heater core 16, and also directly carried into the heater core 16, bypassing the heat storage tank 9. Since a heater 14 is arranged on an inflow circuit 10b on the upstream side of cooling water flow of the heat storage tank 9, the high-temperature cooling water can be supplied to the heat storage tank 9. Namely, the high-temperature cooling water can be stored in the heat storage tank 9, the high-temperature cooling water can be supplied to the heater core 16. Accordingly, the heating in the cabin can be efficiently performed while suppressing the increase in energy (power) consumed by the heater 14.

摘要： PROBLEM TO BE SOLVED: To ensure the dedusting efficiency of a filter during introduction of outside air and simultaneously to improve maximum cooling capacity through reduction of incurring a filter pressure loss during introduction of inside air. SOLUTION: An air filter 30 is arranged at an intermediate portion between the inner peripheral wall 13a of a rotary door 13 for switching inside and outside air to open and close inside air and outside air introduction ports 11 and 12 and a rotary shaft 13c. The one end part 30a of an air filter 30 is positioned at the intermediate of the opening of the inside air introduction port 11 and the inside air introduction port 11 is divided into tow sections by the air filter 30. During introduction of inside air, a flow bypassing the air filter 30 from the lower part of the inside air introduction port 11 directly to the suction port 21 of a fan 22 is formed. This constitution reduces incurring of a filter pressure loss during introduction of inside air and increases an airflow.
