연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

An air conditioner for a vehicle includes a housing for defining an air passage, and the air passage has a main passage and first and second separate passages branched from the main passage. The first separate passage is provided for leading air from the main passage to a front area of a passenger compartment, and the second separate passage is provided for leading air from the main passage to a rear area of the passenger compartment. Furthermore, an evaporator is disposed in the main passage of the housing, and a heat exchanger is disposed in the main passage at a downstream air side of the evaporator in a part area of the main passage. In the air conditioner, a control member is provided to adjust an air flow from the evaporator into the first separate passage and an air flow from the heating heat exchanger into the first separate passage.

What is claimed is: 1. An air conditioner for a vehicle comprising: a housing for defining an air passage through which air flows, the air passage having a main passage and first and second separate passages branched from the main passage; an evaporator, disposed in the main passage of the housing, for cooling air; a heat exchanger for heating air, the heat exchanger being disposed in the main passage at a downstream air side of the evaporator in a part area of the main passage; a control member which is provided to adjust an air flow from the evaporator into the first separate passage and an air flow from the heating heat exchanger into the first separate passage; a limiting wall member extending from an upper end of the evaporator to a lower end of the heat exchanger approximately in an arc shape at a distance from the heat exchanger on a downstream air side of the heat exchanger, wherein: the limiting wall member is separated from the lower end of the heat exchanger to have a rear opening between the lower end of the heat exchanger and the limiting wall member, through which air from the heat exchanger flows into the second separate passage leading to a rear area; the limiting wall member is provided to partition the first separate passage from the main passage; the control member is arranged in the limiting wall member; a partition plate for partitioning the main passage into a cold air passage through which air from the evaporator flows to the first separate passage, and a warm air passage through which air from the heat exchanger flows; the control member is a flexible sheet member at least partly defining a through hole; the limiting wall member has a guide member for guiding the sheet member; the partition plate extends from an end portion of the heat exchanger to a position immediately before the limiting wall member; and the sheet member is displaceable along the limiting wall member in the guide member relative to the partition plate. 2. An air conditioner according to claim 1, wherein: the sheet member is constructed with two sheet portions which are displaceable relative to one another; and an open area of the through hole is adjustable by the two sheet portions. 3. An air conditioner according to claim 1, further comprising a control flap arranged to open and close the rear opening, wherein the control flap adjusts a flow amount of air flowing from the heat exchanger into the second separate passage. 4. An air conditioner according to claim 1, wherein: the control member includes at least one first control element which is arranged between an end of the heat exchanger and a limiting wall of the housing for adjusting an air amount flowing from the evaporator to the first separate passage, and at least one second control element arranged at a downstream air side of the heat exchanger for adjusting an air amount flowing from the heat exchanger to the first separate passage; the heat exchanger is arranged to have a rear opening between a lower end of the heat exchanger and a wall portion of the housing; and through the rear opening, air from the heat exchanger flows to the second separate passage. 5. An air conditioner according to claim 1, further comprising a control flap disposed to open and close the rear opening. 6. The air conditioner according to claim 1, wherein: the air conditioner is in combination with the vehicle; the first separate passage is provided for leading air from the main passage to a front area of a passenger compartment of the vehicle; and the second separate passage is provided for leading air from the main passage to a rear area of the passenger compartment of the vehicle. 7. An air conditioner according to claim 6, wherein: the sheet member is constructed with two sheet portions which are displaceable relative to one another; and an open area of the through hole is adjustable by the two sheet portions. 8. An air conditioner according to claim 6, further comprising a control flap arranged to open and close the rear opening, wherein the control flap adjusts a flow amount of air flowing from the heat exchanger into the second separate passage. 9. An air conditioner according to claim 6, wherein: the control member includes at least one first control element which is arranged between an end of the heat exchanger and a limiting wall of the housing for adjusting an air amount flowing from the evaporator to the first separate passage, and at least one second control element arranged at a downstream air side of the heat exchanger for adjusting an air amount flowing from the heat exchanger to the first separate passage; the heat exchanger is arranged to have a rear opening between a lower end of the heat exchanger and a wall portion of the housing; and through the rear opening, air from the heat exchanger flows to the second separate passage leading to the rear area of the passenger compartment. 10.
