Cinga ngeqela legumbi leenkomfa elingenazifestile elikhonzwa yi-DOAS enokubuyiswa kwamandla kunye nebhloko yangasese yangaphakathi eyahlukileyo. Indlela esebenzayo kukuchaza iyunithi yomoya yangaphandle esekwe kwi-ERV ehambisa i-Vbz ebaliweyo ukuze kuhlale abantu abaninzi kwiintlanganiso ngelixa ibuyisela umoya odala ngendlela yokukhupha umoya okanye indlela yokukhupha umoya ye-ERV. I-ERV inciphisa imithwalo yokufudumeza/yokupholisa emoyeni wokwenza izimonyo, ngelixa ibhanki yesihluzo enamanqanaba amabini ifikelela kwi-MERV 13/ePM1 ≥50% ezantsi kwesiseko sokubuyisela amandla. I-DCV esekwe kwindawo yokuhlala inciphisa ukuhamba phakathi kweentlanganiso; I-BMS ithambekele kwi-CO2 kunye ne-DP yesihluzo ukuqinisekisa okuqhubekayo. Ukuze ufumane uluhlu lwemveliso kunye neemvilophu ze-ESP/zokusebenza kakuhle, jonga i-Airwoods's Iinketho ze-ERV zorhwebo.
Kwicala lendlu yangasese, izinyusi zokukhupha umoya ezinikezelweyo zilinganiswa ngokokusetyenziswa kwe-IMC/ASHRAE minimums, uxinzelelo oluqinisekisiweyo olubi lugcinwa kwiindawo ezikufutshane, kwaye umoya we-makeup ugcinwa ngendlela ye-DOAS ukuze amavumba angafuduki. Isiphumo: umoya ohambelana nekhowudi kunye noxinzelelo kunye nokubuyiswa kwamandla okufanelekileyo kunye nokusebenza okuqinisekisiweyo.
5) Iingxaki ekufuneka uziphephe—nendlela yokuzilungisa
Ukufuduka kwevumba elibi ukusuka kwindlu yangasese ukuya kwiiofisi kudla ngokubangelwa yi-exhaust encinci, ukungabikho kwendlela yokudlulisela umoya wokuthambisa, okanye ukungaphumeleli kolawulo loxinzelelo. Isisombululo silula: qinisekisa i-exhaust ngokwesixhobo/udidi, bonelela ngendlela ecacileyo yomoya wokuthambisa ukusuka kwiindawo ezicocekileyo, kwaye uqinisekise uxinzelelo olubi ngokufundwa komsi kunye ne-Pa ngexesha le-TAB nakwimisebenzi eqhelekileyo.
Ukujikeleza okufutshane kumagumbi eentlanganiso kwenzeka xa iijethi zombane zilahla ngqo kwiindawo ezibuyiselwayo okanye xa ii-diffusers zihleli kwiikona ezimileyo. Beka kwakhona ii-terminals ukukhuthaza ukuxubana kwindawo enabantu, qinisekisa ukuphoswa kunye nokungeniswa kwindlela oyila ngayo, kwaye usebenzise i-CFD kwiindawo zejometri ezintsonkothileyo okanye kwiindawo zeenkomfa ezinobungozi obukhulu.
Ukunyuka koxinzelelo lwefiltha akusoloko kubalwa ekukhetheni ifeni. Nika umda we-DP yokuphela kobomi, itrend enezinzwa, kunye nokuhluza kwesiteji ukwandisa amaxesha. Ukuba abalandeli bahamba ngegophe ekuqaleni, uya kuba usukela iingxaki ubomi bonke benkqubo.
Ii-ERV zemozulu ebandayo zinokubanda ukuba iindlela zokunyibilikisa okanye zokudlula azilungiselelwanga. Qinisekisa ulawulo lwesantya sevili okanye ulandelelwano lokufudumeza/lokudlula, kwaye uzivavanye phantsi kweemeko ezilinganisiweyo. Yongeza ii-alamu zempazamo ukuze i-bypass ebambekileyo ingahlali ixesha elide.
