Return Air Light Fixtures
Two generic types of return air light
fixture are available: those
that allow and those that do not allow
return air to flow through the
lamp chamber. The first type is sometimes
called a heat-of-light
fixture. The percentage of light heat
released through the plenum
side of various ventilated fixtures can be
obtained from lighting fixture
manufacturers. For representative data, see
Nevins et al. (1971).
Even unventilated fixtures lose some heat
to plenum spaces; however,
most of the heat ultimately enters the
conditioned space from
a dead-air plenum or is picked up by return
air via ceiling return air
openings. The percentage of heat to
return air ranges from 40 to
60% for heat-to-return ventilated
fixtures, or 15 to 25% for unventilated
fixtures. 감사합니다. :::: 관리자의 글 ::::
안녕하세요? 저는 RTS-SAREK 프로그램 사용법을 매뉴얼을 따라 배우려는 엔지니어입니다. RTS-SAREK 매뉴얼(p. 82) 입력항목 중 Lighting of RA(%) 값을 참조할 사본(ASHRAE 2005 HoF p 30.4)을 보내주시기 바랍니다. RTS-SAREK 매뉴얼(p. 82)에서 Lighting of RA(%) 값을 ASHRAE 2005 HoF p 30.4를 참조하라 했는데 - 해당 핸드북이 없는 터라 인터넷으로 찾아봐도 찾을 수가 없어서 부탁드립니다. |
