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.

1. An apparatus for controlling refrigerant flow, comprising: at least one refrigerant inlet;at least one refrigerant outlet;a first valve coupled between the at least one refrigerant inlet and the at least one refrigerant outlet; anda second valve coupled between the at least one refrigerant inlet and the at least one refrigerant outlet;wherein at least one of the first valve and the second valve is rotatable, and the first valve and the second valve comprise one or more cooperative openings to allow refrigerant to pass from the at least one refrigerant inlet, through the first valve and the second valve, and out of the at least one refrigerant outlet, andwherein the at least one of the first valve and the second valve is rotatable such that a rate of flow of refrigerant from the at least one refrigerant outlet is selectively: an approximately zero percent refrigerant flow rate;an approximately one hundred percent refrigerant flow rate; andat least one refrigerant flow rate between the approximately zero percent refrigerant flow rate and the approximately one hundred percent refrigerant flow rate. 2. The apparatus of claim 1, further comprising at least a second refrigerant outlet to allow refrigerant to pass from the at least one refrigerant inlet, through the first valve and the second valve, and out of one or more of the refrigerant outlets. 3. The apparatus of claim 2, further comprising at least a second refrigerant inlet to allow refrigerant to pass from one or more of the refrigerant inlets, through the first valve and the second valve, and out of one or more of the refrigerant outlets. 4. The apparatus of claim 1, further comprising a mechanism for rotating at least one of the first valve and the second valve in response to a control signal. 5. The apparatus of claim 1, wherein the one or more cooperative openings of the first valve and the second valve are formed therein such that selective alignment via rotation of at least one of the first valve and the second valve corresponds to selective rates of flow of refrigerant from the at least one refrigerant outlet. 6. The apparatus of claim, 5, wherein the first valve comprises a first set of one or more openings and the second valve comprises a second set of one or more openings. 7. The apparatus of claim 6, wherein at least one of the openings of the first set of one or more openings and the second set of one or more openings comprises a discrete hole feature. 8. The apparatus of claim 6, wherein at least one of the openings of the first set of one or more openings and the second set of one or more openings comprises a continuous slot feature. 9. The apparatus of claim 6, wherein selective alignment of at least one opening of the first set of one or more openings and at least one opening of the second set of one or more openings corresponds to one refrigerant flow rate between the approximately zero percent refrigerant flow rate and the approximately one hundred percent refrigerant flow rate. 10. The apparatus of claim 9, wherein selective alignment of others of the first set of one or more openings and the second set of one or more openings corresponds to other refrigerant flow rates between the approximately zero percent refrigerant flow rate and the approximately one hundred percent refrigerant flow rate. 11. The apparatus of claim 1, further comprising a housing. 12. The apparatus of claim 11, wherein the at least one refrigerant inlet and the at least one refrigerant outlet are formed along one axial line of the housing. 13. The apparatus of claim 11, wherein the at least one refrigerant inlet and the at least one refrigerant outlet are formed in perpendicular relation to one another on the housing. 14. The apparatus of claim 11, wherein the at least one refrigerant inlet and the at least one refrigerant outlet are formed on one side of the housing. 15. A refrigerator appliance comprising: a refrigerant flow control device comprising: at least one refrigerant inlet; at least one refrigerant outlet; a first valve coupled between the at least one refrigerant inlet and the at least one refrigerant outlet; and a second valve coupled between the at least one refrigerant inlet and the at least one refrigerant outlet; wherein at least one of the first valve and the second valve is rotatable, and the first valve and the second valve comprise one or more cooperative openings to allow refrigerant to pass from the at least one refrigerant inlet, through the first valve and the second valve, and out of the at least one refrigerant outlet; anda mechanism for rotating at least one of the first valve and the second valve in response to a control signal,wherein the at least one of the first valve and the second valve is rotatable such that a rate of flow of refrigerant from the at least one refrigerant outlet is selectively: an approximately zero percent refrigerant flow rate;an approximately one hundred percent refrigerant flow rate; andat least one refrigerant flow rate between the approximately zero percent refrigerant flow rate and the approximately one hundred percent refrigerant flow rate. 16. The refrigerator appliance of claim 15, further comprising a microprocessor for generating the control signal. 17.
