Chipatara chekushanda mukamuri yekuchenesa mhepo

Kudzvinyirirwa kwemhepo muimba yekushanda kunosiyana zvichienderana nezvinodiwa zvehutsanana munzvimbo dzakasiyana-siyana (zvakadai sekamuri yekushanda, imba yekugadzirira isina tsvina, imba yekutsvaira, nzvimbo yeanesthesia uye nzvimbo yakapoteredza yakachena, nezvimwewo).Akasiyana mazinga e laminar kuyerera anoshanda makamuri ane akasiyana mhepo kuchena zviyero.Semuenzaniso, US Federal standard 1000 ndiyo nhamba yeguruva particles ≥0.5μm per cubic foot of air, ≤1000 kana ≤35 particles per litre yemhepo.Iyo chiyero chekirasi 10000 laminar inoyerera yekushanda kamuri ndiyo nhamba yeguruva zvidimbu≥0.5μm pa cubic tsoka yemhepo, ≤10000 kana ≤350 zvimedu parita yemhepo.Zvichingoenda zvakadaro.Chinangwa chikuru chekufefetera mukamuri yekuvhiya ndechekubvisa iyokupera gasimuimba imwe neimwe yekushanda;Ita shuwa huwandu hunodiwa hwemweya mutsva munzvimbo dzese dzebasa;Bvisa guruva uye microorganisms;Chengetedza kudikanwa kwakanaka kwakanaka muimba.Kune maviri mechanical ventilation modes anogona kusangana neventilation zvinodiwa zveimba yekushandisa.Mechanical mweya wekupa uye kupera simba: Iyi modhi yekufefetera inogona kudzora huwandu hwekutsinhana kwemhepo, kuchinjana kwemhepo uye kudzvanywa kwemukati, uye mhepo yekufema iri nani.Mechanical mweya wekupa uye kupera kwechisikigo kunoshandiswa, uye kufefetedza uye kuwanda kweiyi nzira yekufemesa kunogumira, uye mhedzisiro yemhepo haina kunaka seyaimbova.Hutsanana nhanho yekamuri yekushandisa inonyanya kusiyaniswa nehuwandu hweguruva zvidimbu uye biological particles mumhepo.Parizvino, inonyanya kushandiswa ndiyo NASA classification standard.Tekinoroji yekunatsa kuburikidza nekunatswa kwakanaka kunopa mhepo inoyerera inodzora hutsanana kuzadzisa chinangwa che sterility.
