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.

A vehicle climate control system includes a thermal-adsorption heat pump driven by engine exhaust heat, the heat pump including two adsorbers asynchronously switching between adsorbing and desorbing modes, each adsorber coupled with a corresponding antifreeze tank via a plurality of refrigerant-containing wick chambers. Cold heat transfer fluid (HTF) flows through the adsorber during the adsorbing mode which causes evaporation of refrigerant from the wick chambers, thereby cooling antifreeze, whereas hot HTF flows through the adsorber during the desorbin...

The method of claim 2, wherein conditioning cabin air during a summer mode comprises exchanging heat between antifreeze from the antifreeze tank of the adsorbing adsorber and cabin air, and wherein conditioning cabin air during a mild or severe winter mode comprises exchanging heat between antifreeze from the antifreeze tank of the desorbing adsorber and outside air and directing the heated outside air to the cabin. 4. The method of claim 3, further comprising: cooling heat transfer fluid (HTF) via an HTF cooler in a cold HTF circuit;exchanging heat between engine exhaust and HTF in a hot HTF circuit;pumping HTF from the cold HTF circuit through one or more fin tubes thermally coupled with an adsorbent in the adsorbing adsorber; andpumping HTF from the hot HTF circuit through one or more fin tubes thermally coupled with an adsorbent in the desorbing adsorber. 5. The method of claim 4, further comprising: during the summer mode, cooling antifreeze from the antifreeze tank of the desorbing adsorber via heat exchange with outside air;during the mild winter mode, heating antifreeze from the antifreeze tank of the adsorbing adsorber via heat exchange with outside air; andduring the severe winter mode, heating antifreeze from the antifreeze tank of the adsorbing adsorber via heat exchange with HTF from the hot HTF circuit. 6. The method of claim 5 further comprising: after engine shutdown during the summer mode, operating both adsorbers in the desorbing mode for a duration via heat exchange between HTF from the hot HTF circuit and the adsorbents of both adsorbers;after engine shutdown during the mild or severe winter mode, operating both adsorbers in the adsorbing mode for a duration via heat exchange between HTF from the cold HTF circuit and the adsorbents of both adsorbers; and thendecoupling the wick chambers of each adsorber from the corresponding adsorber enclosure. 7. The method of claim 6 further comprising, at or prior to engine start; coupling the wick chambers of each adsorber with the corresponding adsorber enclosure;in a surge cooling mode prior to summer mode operation, operating both adsorbers in the adsorbing mode for a duration; andin a surge heating mode prior to mild or severe winter mode operation, operating both adsorbers in the desorbing mode for a duration. 8. The method of claim 7, further comprising activating the surge cooling or heating modes prior to engine start responsive to remote control by a user. 9.
