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 automatically operable dynamic purge system that is incorporated into a heat recovery wheel that comprises a number of radial seals that direct a controlled area of supply air into the exhaust air stream passing through the heat recovery wheel. Two possible configurations include a single purge and a double purge. For the single purge, one seal is fixed in location on one face of the wheel and a second seal is dynamic and is on the opposite face. For the double purge, two seals are fixed in location on one face of the wheel and a third seal is dynamic and is on the opposite face. In each case the dynamic seal is secured by an automatically operable wiper blade. This wiper blade is attached near the center of the wheel such that it rotates, in turn, allowing the seal to rotate while remaining approximately radial to the wheel.

1. An automatic operable, dynamic purge system for a heat recovery wheel comprising: a heat recovery wheel assembly having one or two fixed radial seals and a dynamically movable radial seal, said one or two fixed radial seals and said dynamically movable radial seal being configured for directing a controlled supply of air into an exhaust air stream passing through a heat recovery wheel of said assembly, wherein said one or two radial fixed seals are on one face of said heat recovery wheel and said dynamically movable radial seal and is located on an opposite face of said heat wheel recovery;wherein when said heat recovery wheel includes said one fixed radial seal and said dynamically movable radial seal, said fixed and dynamic seals are located to create a single purge so that purged air travels through said wheel once, and wherein when said heat recovery wheel includes said two fixed radial seals and said dynamically movable radial seal, said fixed and dynamic radial seals are located to create a double purge so that purged air travels through said wheel twice,said dynamically movable radial seal being secured by an automatically operable rotatable wiper blade, wherein as said wiper blade rotates, said dynamically movable radial seal rotates while remaining approximately radial to said heat recovery wheel. 2. The system according to claim 1, further comprising: means for altering an effective angle of said single or double purge by moving said wiper blade to a desired optimal position based on time varying air flow conditions and predetermined input data calculated by a control system. 3. The system according to claim 2, wherein said means for altering said effective angle of said single or double purge by moving said wiper blade to said desired optimal position based on said predetermined input data comprises actuator means in mechanical communication with said wiper blade. 4. The system according to claim 2, wherein said predetermined input data includes one of or any combination of: data related to an air velocity at an exit side of a first pass through a purge section;data related to first air velocity at said exit side of said first pass through said purge section and data related to a second air velocity at a second exit of a second pass through said purge section;data related to a first air pressure at said exit side of said first pass through said purge section, and data related to a second air pressure at an entry side before a supply air enters said purge section;data related to a first air pressure at said exit side of said first pass through said purge section, data related to a second air pressure at a second exit of a second pass through said purge section and data related to a third air pressure at an entry side before a supply air enters said purge section; anddata related to temperature at an exit side of a first pass through said purge section. 5. The system according to claim 1, further comprising: means for maintaining a planar motion of said wiper blade. 6. A method for directing a controlled supply of air into an exhaust air stream passing through a heat recovery wheel of a heat recovery wheel assembly, the method comprising: providing a heat recovery wheel assembly having one or two fixed radial seals and a dynamically movable radial seal, said one or two fixed radial seals and said dynamically movable radial seal being configured for directing a controlled supply of air into an exhaust air stream passing through a heat recovery wheel of said assembly, wherein said one or two fixed seals are on one face of said heat recovery wheel and said dynamically movable radial seal and is located on an opposite face of said heat recovery wheel, wherein when said heat recovery wheel includes said one fixed radial seal and said dynamically movable radial seal, said fixed and dynamic seals are located to create a single purge so that purged air travels through said wheel once, and wherein when said heat recovery wheel includes said two fixed radial seals and said dynamically movable radial seal, said fixed and dynamic seals are located to create a double purge so that purged air travels through said wheel twice, wherein said dynamically movable radial seal is secured by a rotatable wiper blade, wherein as said wiper blade rotates, said dynamically movable radial seal rotates while remaining approximately radial to said heat recovery wheel;providing means for altering an effective angle of said single or double purge by automatically moving said wiper blade to a desired optimal position based on time varying air flow conditions and predetermined input data calculated by a control system; anddirecting a controlled supply of air into an exhaust air stream passing through said heat recovery wheel of said heat recovery wheel assembly by moving said wiper blade to said desired optimal position based on said predetermined input data calculated by said control system, wherein said predetermined input data includes one of or any combination of:data related to an air velocity at an exit side of a first passthrough a purge section;data related to first air velocity at said exit side of first pass through said purge section and data related to a second air velocity at a second exit of a second pass through said purge section;data related to a first air pressure at said exit side of said first pass through said purge section, and data related to a second air pressure at an entry side before a supply air enters said purge section;data related to a first air pressure at said exit side of said first pass through said purge section, data related to a second air pressure at a second exit of a second pass through said purge section and data related to a third air pressure at an entry side before a supply air enters said purge section; anddata related to temperature at an exit side of a first pass through said purge section. 7. The method according to claim 6, wherein said means for altering said effective angle of said single or double purge by moving said wiper blade to said desired optimal position based on said predetermined input data comprises actuator means in mechanical communication with said wiper blade. 8. The method according to claim 6, further comprising: providing means for maintaining a planar motion of said wiper blade.
