Nguva pfupi yadarika, kumwe kubuda kwekoronavirus cross-infection kwakataurwa munzvimbo yakavharwa yakavharwa.Kutangwa kwakakura kwemakambani / zvikoro / zvitoro zvikuru nzvimbo dzeveruzhinji munyika yose kwatipa humbowo hutsva hwekuti coronavirus inogona kudzivirirwa sei munzvimbo dzine vanhu vakawanda zvivakwa zveveruzhinji.
Kubva kunyaya dzehupenyu dzekutapukirwa, mutirongo rakavharwa, mune vanhu mazana maviri nevanomwe vakatapukirwa, uye muchikepe cheDiamond Princess cruise, vanhu vanopfuura mazana mashanu vanotapukirwa.Mienzaniso iyoyo yakaratidza kwatiri kuti munzvimbo dzine vanhu vakawanda, kunyanya nzvimbo yakavharwa, ingave nzvimbo yakavharwa yevashandi vane mamiriro akareruka kana chikepe chemhando yepamusoro, zvinotungamira mukutapukira nekuda kwekushaikwa kwemhepo kana dambudziko rekushanda kwechikepe. air conditioning system.
Zvino ngatitorei chivakwa chakajairwa semuenzaniso wekuongorora hurongwa hwayo hwekufemesa, uye kuona kuti kudzora sei kutapukira-kutapukira munzvimbo dzine vanhu vakawanda.
Heino marongerwo ejeri chairo.Maererano nemirairo yezvivakwa zvakadaro, kuti nhamba yevanhu vari muimba yevarume kana yevakadzi haifaniri kudarika 20.Iyi inyanzvi yepakati nepakati ine 12 bunk mibhedha pakamuri.

Kuitira kudzivirira vasungwa kutiza, nzvimbo yekupinza mhepo yekunze inowanzogadzirwa kuti ive diki kwazvo.Chirevo chacho chinonyatsoratidza kuti hwindo rinorambidzwa kudarika 25cm. Kazhinji, mhepo yekamuri imwe neimwe iri pakati pe10 ~ 20cm.Nekuti imba yacho yakagadzirirwa nepamusoro uye pasi mabhandi, kureba hakusi pasi pe3.6m maererano nekuvakwa kwejeri. mitemo.Saka saizi yekutanga yejeri iri ingangoita 3.9m yakafara, 7.2m kureba, 3.6m kureba, uye huwandu hwese hunosvika 100m3.
Kune maviri masimba ekufambisa kwemhepo yepanyama, imwe ndeyekumanikidza kwemhepo uye imwe ndeyekupisa kwemhepo.Nekuverenga, kana jeri rakadaro rine kunze kwekuvhura kwe20cm ne20cm uye rinovhurwa pakakwirira kudarika 3m, iyo yose yemhepo yemhepo. yekamuri inofanira kuva pakati pe0.8 uye 1h-1.Izvo zvinoreva kuti mhepo muimba inogona kuchinjwa zvachose inenge awa imwe neimwe.

Saka nzira yekutonga iyo ventilation system yakanaka kana yakaipa?
Chiratidzo chakakosha ivhoriyamu chikamu checarbon dioxide.Vanhu vakawanda, kufefetedza kwakashata, indoor carbon dioxide volume fraction ichasimuka, kunyange zvazvo carbon dioxide pachayo isinganhuhwi, asi ichiratidzo.
Makore anopfuura 100 apfuura, Max Joseph Pettenkofer, muGermany uyo akatanga kuunza pfungwa yemhepo, akabuda nemaitiro akaenzana ehutano: 1000 × 10-6. Iyi index yakave ine chiremera kusvikira zvino.Kana iyo yemukati kabhoni vhoriyamu chikamu chikamu ichidzorwa pazasi 1000 × 10-6, mhepo ine hutano nharaunda inogona kuchengetedzwa, uye vanhu havagone kutapurirana zvirwere kune mumwe nemumwe.

Saka chii chinonzi volume part yecarbon dioxide mumba muno?Isu takaita kuenzanisa calculation, kana vanhu gumi nevaviri vachionekwa sevari mukunyepa.Nekureba kwekamuri rakadaro, saizi yekamuri uye vhoriyamu yemhepo, iyo yakagadzikana vhoriyamu chikamu chekabhoni dhaibhorosi ndeye 2032 × 10-6, iyo inenge yakapetwa kaviri chiyero che1000 × 10-6.
Handisati ndamboenda kunzvimbo yakavharwa yekutonga, asi zvinoita sekuti vanhu vanowanzotaura kuti mhepo ine tsvina.
Zviitiko zviviri izvi, kunyanya chiitiko chechangobva kuitika chezvirwere mazana maviri nenomwe, zvinotipa yambiro huru yekuti kutangazve basa munzvimbo dzine vanhu vakawanda kunoda kungwarira.
Nzvimbo yakatsvikinyidzana inonyatso gadzira mhedzisiro yakafanana ndiyo kirasi.Mukirasi kazhinji mune vadzidzi vanenge 50 vakaungana pamwechete.Uye vanowanzogara kwemaawa mana kusvika mashanu.Munguva yechando, vanhu havazosarudze kuvhura mahwindo emhepo, nekuti kunotonhora.Pane njodzi yehutachiona hwemuchinjikwa.Kana iwe ukayera vhoriyamu chikamu checarbon dioxide mukirasi yakazara nevanhu munguva yechando, vazhinji vavo vanopfuura 1000 × 10-6.
Iyo inonyanya kushanda nzira yekubata nekuchinjika-kutapukira kwekoronavirus, uye inenge nzira imwe chete iripo, kufefetedza.
Nepo iyo inonyanya kushanda nzira yekuona kufefetera ndeyekuyera carbon dioxide volume.Isu tinonyatsoziva kuti kana iyo Co2 vhoriyamu isingasviki 550 × 10-6, umo zvakatipoteredza zvakachengeteka zvakanyanya, kunyange kana pane mumwe munhu murwere muimba. Pane zvakasiyana, tinogona kuziva , kana carbon dioxide volume yakawanda. kupfuura 1000 × 10-6, haina kuchengeteka.
Mamaneja ezvivakwa anofanira kutarisa zvivakwa mamiriro emhepo mazuva ese.Kana uchinetseka, tora chiridzwa uende nacho.Kana zvisina kudaro, shandisa mhino yako.Mhino yemunhu ndiyo yakanakisa uye inonzwa detector, Kana mamiriro emhepo asina kunaka, mhanya nekukurumidza sezvaunokwanisa.
Ikozvino nzanga iri kudzoka zvishoma nezvishoma kune zvakajairika kugadzirwa nebasa, isu tinofanirwa kungwarira zvakanyanya sezvatingagona kana tiri munzvimbo yakavharwa, senge pasi pevhu zvitoro, mikoto yepasi pevhu, pamwe nedzimba dzekudzidzira, dzimba dzekumirira uye dzimwe nzvimbo dzakazara vanhu.
