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.

We claim: 1. A heating and cooling system for a vehicle, the heating and cooling system comprising: a first circuit having a first pump for circulating a first medium therethrough; a second circuit having a second pump for circulating a second medium therethrough; a first heat exchanger in thermal communication with the first medium; a second heat exchanger in thermal communication with the second medium; and a thermoelectric module having a first surface in thermal communication with the first heat exchanger and a second surface in thermal communication with the second heat exchanger, whereby the second surface is performing one of heating and cooling the second medium; wherein the system is configured to heat a passenger compartment of the vehicle when a heating mode is selected; wherein current flows in a first direction through the thermoelectric module such that the first surface cools the first heat exchanger and the second surface heats the second heat exchanger when the heating mode is selected; wherein the system is further configured to cool the passenger compartment of the vehicle when a cooling mode is selected; and wherein current flows in a second direction through the thermoelectric module such that the first surface warms the first heat exchanger and the second surface cools the second heat exchanger when the cooling mode is selected. 2. A heating and cooling system for a vehicle, the heating and cooling system comprising: a first circuit having a first pump for circulating a first medium therethrough; a second circuit having a second pump for circulating a second medium therethrough; a first heat exchanger in thermal communication with the first medium; a second heat exchanger in thermal communication with the second medium; a thermoelectric module having a first surface in thermal communication with the first heat exchanger and a second surface in thermal communication with the second heat exchanger, whereby the second surface is performing one of heating and cooling the second medium; and an engine being operatively engaged with the first circuit. 3. The system of claim 2, further comprising a third heat exchanger in thermal communication with the first medium. 4. The system of claim 3, further comprising a blower configured to move air through the third heat exchanger. 5. The system of claim 2, further comprising a third heat exchanger in thermal communication with the second medium. 6. The system of claim 5, further comprising a blower configured to move air through the third heat exchanger. 7. The system of claim 2, further comprising a third heat exchanger being operatively engaged with the first circuit. 8. The system of claim 7, wherein the third heat exchanger is a radiator. 9. The system of claim 7, wherein the first circuit further comprises an at least one bypass line and an at least one valve configured to direct the first medium through one of the at least one bypass line and the first heat exchanger. 10. The system of claim 2, wherein the first circuit further comprises an at least one bypass line, wherein the first medium is circulated through the at least one bypass line, thereby preventing the first medium from being in thermal communication with the first heat exchanger. 11. The system of claim 10, further comprising an at least one double switching valve configured to direct the first medium through one of the at least one bypass line and the first circuit in thermal communication with the first heat exchanger. 12. A heating and cooling system for a vehicle, the heating and cooling system comprising: a first circuit having a first pump for circulating a first medium therethrough; a second circuit having a second pump for circulating a second medium therethrough; a first heat exchanger in thermal communication with the first medium; a second heat exchanger in thermal communication with the second medium; a thermoelectric module having a first surface in thermal communication with the first heat exchanger and a second surface in thermal communication with the second heat exchanger, whereby the second surface is performing one of heating and cooling the second medium; and a third circuit having a third pump, a valve and a sixth heat exchanger, the third circuit being connected to the first circuit. 13. The system of claim 12, further comprising a cold generating system being operatively engaged with the third circuit. 14. The system of claim 13, wherein the third circuit further comprises an at least one bypass line and an at least one valve configured to direct the first medium through one of the at least one bypass line and the cold generating system. 15.
