< Topic >Modification construction does not become large-scale, be able to compact term of works, as cost can be reduced, the sterile ward and relay unit of the vertical laminar flow type where degree of freedom of layout is high, can maintain under sterile environment with the energy conservation are offered.SolutionsIt is installed inside the roof of the ward the fresh air which sterile is purified as the vertical laminar flow which falls from the roof surface in the sterile ward of the vertical laminar flow type which it supplies, from the roof surface directs to the lower part and the air conditioner unit it is installed under the bed of 2 which supplies the fresh air which sterile is purified and the patient, absorbs the air around the said bed and it is installed alongside relay unit T1 and the wall of the ward which the exhaust air are done in cross direction, the duct panel 3 which possesses absorption opening 3a in lower part and, it provides.< Choice figure >Drawing 1【課題】改修工事が大掛かりとならず、工期を短縮でき、コストを削減できるとともに、レイアウトの自由度が高く、無菌環境下を省エネルギーで維持できる垂直層流タイプの無菌病室及び中継ユニットを提供する。【解決手段】無菌・清浄化された新鮮な空気を天井面から下降する垂直層流として供給する垂直層流タイプの無菌病室において、病室の天井内に設置され、天井面から下方に向けて無菌・清浄化された新鮮な空気を供給する空調機ユニット2と、患者のベッド下に設置され、該ベッドの周囲の空気を吸引して横方向に排気する中継ユニットT1と、病室の壁に沿って設置され、下部に吸引口3aを有するダクトパネル3と、を設ける。【選択図】図1
