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 method, comprising during a vehicle engine cold start, opening a first valve coupled between a first container containing an adsorbent and a second container containing an adsorbate, circulating a first fluid through a first conduit coupled to a first heat exchanger located within the first container and a second heat exchanger located outside the first container, and circulating a second fluid through a second conduit coupled to the second heat exchanger. In this way, heat may be generated at the adsorber during a cold start and subsequently transferr...

1. A method, comprising: during a vehicle engine cold start: opening a first valve coupled between a first container containing an adsorbent and a second container containing an adsorbate to flow the adsorbate from the second container to the first container for adsorption at the adsorbent;exchanging heat between the adsorbent in the first container and a first fluid by circulating the first fluid in a coolant/adsorber heat exchange loop through a first heat exchanger located within the first container and a second heat exchanger located outside the first container, the first heat exchanger thermally coupled with the adsorbent; andexchanging heat between the first fluid and a second fluid by circulating the second fluid through a coolant circuit including the second heat exchanger. 2. The method of claim 1, where circulating the second fluid through the coolant circuit further includes circulating the second fluid through a cooling jacket of a vehicle engine. 3. The method of claim 2, further comprising: allowing the vehicle engine to reach a predetermined running temperature; and thenstopping circulation of the first fluid in the coolant/adsorber heat exchange loop. 4. The method of claim 3, further comprising: circulating a third fluid in a heat recovery loop through a third heat exchanger located within the first container and a fourth heat exchanger located outside the first container and thermally coupled to a waste heat source;activating a fan coupled to the second container;allowing the adsorbate in the second container to reach a predetermined threshold level;closing the first valve;stopping circulation of the third fluid; andde-activating the fan coupled to the second container. 5. The method of claim 4, where the waste heat source is an exhaust passage coupled to the vehicle engine. 6. The method of claim 2, where circulating the second fluid through the coolant circuit further includes circulating the second fluid through a radiator and a third container, where the third container is a reservoir containing the second fluid. 7. The method of claim 6, where circulating the second fluid through the coolant circuit further includes circulating the second fluid through a heating circuit of the coolant circuit, the heating circuit including a heater core used for warming a passenger cabin of the vehicle. 8. The method of claim 1, where the adsorbent is zeolite and the adsorbate is an aqueous solution. 9. A thermal management system for a vehicle, comprising: an adsorption thermal storage device comprising a first container including an adsorbent coupled via a first valve to a second container including an adsorbate;a coolant/adsorber heat exchange loop in which a first coolant circulates, the coolant/adsorber heat exchange loop including a first heat exchanger located within the first container and a second heat exchanger located outside the first container, the first heat exchanger thermally coupled with the adsorbent; anda coolant circuit in which a second coolant circulates, the coolant circuit including the second heat exchanger and a first warming target. 10. The system of claim 9, further comprising: a heat recovery loop in which a third coolant circulates, the heat recovery loop including a third heat exchanger located within the first container and a fourth heat exchanger located outside of the first container, the fourth heat exchanger thermally coupled with a waste heat source. 11. The system of claim 10, where the coolant circuit further includes a second warming target and a third container, wherein the third container is a reservoir containing the second coolant. 12. The system of claim 11, further comprising: a heating circuit, the heating circuit including a second valve and a third warming target, wherein the heating circuit is included in the coolant circuit when the second valve is open. 13. The system of claim 12, further comprising: a controller configured with instructions stored in memory for: in response to a request for heat for the first warming target, opening the first valve, circulating the first coolant through the coolant/adsorber heat exchange loop and circulating the second coolant through the coolant circuit. 14. The system of claim 13, where the controller is further configured with instructions stored in memory for: in response to a request for heat for the third warming target, opening the second valve, circulating the second coolant through the heating circuit, and activating a first fan coupled to the third warming target. 15. The system of claim 13, where the controller is further configured with instructions stored in memory for: in response to a level of adsorbate in the second container being below a first threshold, stopping circulation of the first coolant through the coolant/adsorber heat exchange loop, opening the first valve, circulating the third coolant through the heat recovery loop, activating a second fan coupled to the second container, allowing the level of adsorbate in the second container to reach a second threshold higher than the first threshold, closing the first valve and de-activating the second fan and stopping circulation of the third coolant through the heat recovery loop. 16. The system of claim 14, where the first warming target is a cooling jacket of a vehicle engine, the second warming target is a radiator and the third warming target is a heater core used for warming a passenger cabin of the vehicle. 17. The system of claim 10, where the waste heat source is an exhaust passage coupled to a vehicle engine, and the third coolant is a high temperature heat transfer fluid. 18. The system of claim 9, where the first warming target is a heater core used for warming a passenger cabin of the vehicle. 19. A warm-up system for a vehicle engine, comprising: an adsorption thermal storage device comprising an adsorber containing an adsorbent coupled via a valve to a fluid tank containing an adsorbate;a coolant/adsorber heat exchange loop containing a first coolant, the coolant/adsorber heat exchange loop including a first heat exchanger located within the adsorber and a second heat exchanger located outside the adsorber;a coolant circuit containing a second coolant, the coolant circuit including the second heat exchanger and further including a cooling jacket of the vehicle engine; anda controller configured with instructions stored in memory for: in response to a cold start event, opening the first valve, circulating the first coolant through the coolant/adsorber heat exchange loop, and circulating the second coolant through the coolant circuit.
