摘要:
When the engine is stopped while the engine is warmed up, the cooling water in the engine stays therein without flowing out of the engine, and the cooling water in the radiator or the bypass passage is used for heating source for the heating operation. In this way, it is possible to heat the passenger compartment continuously even after the engine is stopped and to suppress the temperature of the cooling water from lowering to reduce the emission at restarting of the engine.

According to the present invention, in a brine type air-conditioning apparatus in which brine circulates into an inside cooler to cool a passenger compartment, there are provided a refrigeration cycle using flammable gas as refrigerant, a brine circuit in which the brine circulates, a hot water circuit in which hot water heated by an engine circulates, a front air-conditioning unit for performing an air-conditioning of a front portion in the passenger compartment, a rear air-conditioning unit for performing an air-conditioning of a rear portion in the passenger compartment. In the front air-conditioning unit, there are provided a cooler for cooling conditioned air by using the brine, a heater for heating conditioned air by using the hot water, a blower. In the rear air-conditioning unit, there are provided an air-conditioning heat exchanger for cooling conditioned air by using the brine and for heating conditioned air by using the hot water, and a blower. For adjusting a temperature of the low-temperature side, the heating amount by the heater is set to zero, and a temperature of the brine is variably controlled by varying a capacity of the refrigeration cycle.

An automotive air conditioner includes an offset blower for blowing an air, an evaporator is centrally disposed within a dashboard and receives the air from below, and a heater approximately horizontally disposed above the evaporator. The evaporator inclines downward along the direction of the air flow. A plurality of condensed water guide plates are provided under the evaporator so as to allow a condensed water smoothly flow on the surface of each guide plate and is discharged from the evaporator through a condensed water drain pipe.

In a vehicle air conditioner, a cold accumulator is disposed at a downstream air side of an evaporator to be cooled by cold air after passing through the evaporator. A cold accumulating material is sealed within the cold accumulator to be solidified while being cooled by the cold air from the evaporator. The cold accumulating material is a mixture of plural kinds of paraffin materials having different melting points, equal to or more than two. The plural kinds of the paraffin materials are mixed, so that the cold accumulating material having a melting point in a range of 7-11° C. can be obtained. In this case, cooling function in the cold accumulator can be improved.

A thermoelectric converter has a N-type thermoelectric element, a P-type thermoelectric element, an endothermic electrode and a radiative electrode. One surface of the N-type thermoelectric element is attached to one surface of the endothermic electrode and the other surface is attached to one surface of the radiative electrode. One surface of the P-type thermoelectric element is attached to the other surface of the radiative electrode and the other surface is attached to the other endothermic electrode.

In a vehicle air-conditioning system, an evaporator is disposed in an air-conditioning case to form a bypass passage through which air bypasses the evaporator, and an opening degree of the bypass passage is adjusted by a bypass door. When a vehicle engine operates, the system performs a cold-storing mode where cold quantity stored in condensed water on the evaporator is increased. On the other hand, when operation of the vehicle engine is stopped, the system performs a cold-releasing mode where air passing through the evaporator is cooled by cold released from frozen condensed water. During the cold-storing mode and the cold-releasing mode, temperature of air blown into a passenger compartment can be adjusted by adjusting the opening degree of the bypass passage. Thus, in the vehicle air-conditioning system, cold-storing quantity in the evaporator can be improved while power-saving effect of the vehicle engine is improved.

An electric power unit is composed of a secondary battery, a cooling fan, a fan motor and a case for the secondary battery, the cooling fan and the fan motor. The case has a partition for isolating the fan motor from the secondary battery and cooling fan. A magnetic joint is disposed between the motor and the cooling fan.
摘要:
An electric element (Peltier element composite) is disposed in a boundary between an outside air introduction passage and an inside air introduction air passage (114). The Peltier element composite absorbs heat from the inside air in the inside air introduction passage to cool and dehumidify the inside air and radiates heat to outside air in the outside air introduction passage. The inside air and outside air are blown out from a defroster air outlet through a second air passage. In this way, it is possible to increase an amount of introduced inside air and to improve the heating performance while maintaining the defrosting performance.
