Kuyini Umswakama Olinganiselwe? Kungani Umswakama Olinganiselwe Ubaluleke Kangaka Ekulinganisweni Kwansuku Zonke?

Umswakama ohlobene (RH) wengxube yomoya namanzi uchazwa njengesilinganiso sokucindezela okungaphelele komhwamuko wamanzi () engxubeni kuya kokucindezela komhwamuko wokulingana wamanzi ()phezu kobuso obuyisicaba bamanzi ahlanzekile ekushiseni okunikeziwe:

Ngamanye amazwi, umswakama ohlobene yisilinganiso senani lomhwamuko wamanzi emoyeni nenani lomhwamuko wamanzi umoya ongase uwuquke ezingeni lokushisa elithile. Kuyahlukahluka kuye ngezinga lokushisa: umoya obandayo ungabamba umhwamuko omncane. Ngakho-ke ukushintsha izinga lokushisa lomoya kuzoshintsha umswakama ohlobene ngisho noma umswakama ophelele uhlala ungaguquki.

Umoya obandayo wandisa umswakama futhi ungabangela ukuthi umhwamuko wamanzi ujiye (iphuzu lokugcwala uma umswakama ohlobene ukhuphuka ngaphezu kuka-100%). Ngokufanayo, umoya ofudumele wehlisa umswakama ohlobene. Ukushisa umoya othile oqukethe inkungu kungabangela ukuthi inkungu iphele, njengoba umoya ophakathi kwamaconsi amanzi uba namandla okugcina umhwamuko wamanzi.

Umswakama olinganiselwe ubheka kuphela umhwamuko wamanzi ongabonakali. Inkungu, amafu, inkungu kanye nama-aerosol amanzi awabalwa ngokulinganisa umswakama olinganiselwe womoya, yize ukuba khona kwawo kubonisa ukuthi umzimba womoya ungase usondele endaweni yamazolo.

Umswakama ohlobenengokuvamile kuvezwa njengephesenti; iphesenti eliphezulu lisho ukuthi ingxube yomoya namanzi inomswakama kakhulu. Uma kunomswakama ongu-100%, umoya ugcwele futhi usezingeni lamazolo. Uma kungekho mzimba wangaphandle ongenza amaconsi noma amakristalu abe yi-nucleate, umswakama ohlobene ungadlula u-100%, lapho kuthiwa umoya ugcwele kakhulu. Ukufaka ezinye izinhlayiya noma ubuso emzimbeni womoya onomswakama ohlobene ngaphezu kuka-100% kuzovumela ukwakheka komswakama noma iqhwa kulawo ma-nuclei, ngaleyo ndlela kususwe omunye womswakama futhi kuncishiswe umswakama.

I-RelativUmswakama we-e uyisilinganiso esibalulekile esisetshenziswa ekubikezelweni kwesimo sezulu kanye nemibiko, ngoba kuyinkomba yokuthi kungenzeka kube nemvula, amazolo, noma inkungu. Esimweni sezulu esishisayo sasehlobo, ukwanda komswakama ohlobene kuvimbela ukuhwamuka komjuluko esikhumbeni, kuphakamise izinga lokushisa elibonakalayo kubantu (nezinye izilwane). Isibonelo, ekushiseni komoya okungu-80.0 °F (26.7 °C), umswakama ohlobene ongu-75% uzwakala njengo-83.6 °F ±1.3 °F (28.7 °C ±0.7 °C), ngokusho kwe-Heat Index.

Isizathu esikhulu kakhulu sokuqapha umswakama ohlobene ukulawula umswakama ozungeze umkhiqizo wokugcina. Ezimweni eziningi lokhu kusho ukuqinisekisa ukuthi i-RH ayilokothi ikhuphuke kakhulu. Isibonelo, ake sithathe umkhiqizo onjengoshokoledi. Uma i-RH endaweni yokugcina ikhuphuka ngaphezu kwezinga elithile futhi ihlala ngaphezu kwalelo zinga isikhathi eside ngokwanele, kungenzeka into ebizwa ngokuthi ukuqhakaza. Yilapho umswakama wakheka khona ebusweni beshokoledi, uncibilikise ushukela. Njengoba umswakama uphela, ushukela wakha amakristalu amakhulu, okuholela ekushintsheni kombala.

Umswakama nawo ungaba nomthelela omkhulu futhi obizayo emikhiqizweni efana nezinto zokwakha. Ake sithi wandisa indawo yakho futhi ubeka phansi kwekhonkrithi ngaphambi kokubeka phansi okunzima. Uma ikhonkrithi ingomi ngokwanele ngaphambi kokubeka phansi, ingabangela izinkinga ezinkulu, njengoba noma yimuphi umswakama kukhonkrithi uzozama ukuthuthela endaweni eyomile, kulokhu izinto zokwakha phansi. Lokhu kungabangela ukuthi phansi kuvuvuke, kuqhume amabhamuza, noma kuqhekeke, kushiye wonke umsebenzi wakho onzima futhi kungashiyi nketho ngaphandle kokufaka okunye esikhundleni salokho.

Umswakama nawo uyinkinga enkulu emikhiqizweni ezwela kakhulu umswakama njengemithi ethile. Lokhu kungenxa yokuthi ingashintsha izici zomkhiqizo uze ungabi usizo, yingakho imikhiqizo efana namaphilisi kanye nophudingi owomile igcinwa ngaphansi kwezimo ezilawulwayo emazingeni omswakama aqondile kanye namazinga okushisa.

Okokugcina, umswakama ohlobene nawo uyisici esibalulekile ekwakheni izinhlelo zokwenza izinto ngokuzenzakalela ezigxile ekunethezekeni kwabantu, njengomoya opholile. Ikhono lokulinganisa nokulawula umswakama ohlobene alisizi nje kuphela ekugcineni indawo ekhululekile ngaphakathi kwesakhiwo, kodwa futhi lisiza ekwenzeni ngcono ukusebenza kahle kwe-I-HVACizinhlelo, njengoba kungabonisa ukuthi umoya wangaphandle udinga ukulawulwa kangakanani, kuye ngokushisa kwangaphandle.
