Izakhiwo zezemidlalo zineempawu zendawo enkulu, ukuqhubela phambili okunzulu, kunye nomthwalo omkhulu obandayo. Ukusetyenziswa kwayo kwamandla kuphezulu, kwaye kunzima ukuqinisekisa umgangatho womoya wangaphakathi. Umphunga opholileyo womoya uneempawu zempilo, ukonga amandla, uqoqosho, kunye nokhuseleko lokusingqongileyo, kwaye unokudala nokugcina imeko yezemidlalo etofotofo kubantu.

Okwangoku, kukho iimeko ezininzi zokunyuka kunye nokupholisa iteknoloji yezakhiwo zemidlalo. Kukho iimeko ezininzi zokunyuka kwamanzi kunye neteknoloji yokupholisa. Eli nqaku lidwelisa ezi zicwangciso zilandelayo.

(1) Umphunga air-conditioning inkqubo yokupholisa umoya, oko kukuthi, umoya wangaphandle umoya omtsha umphunga umoya-conditioner ukucocwa kunye nokupholisa processing, kwaye uyithumele kwigumbi emva dilution yomoya omdaka yangaphakathi kwaye ukhuphe ngqo ngqo ngaphandle.
(2) Wonke umoya uba ngumphunga kunye nenkqubo yokupholisa umoya yokupholisa umoya. Phakathi kwazo, kwiindawo ezomileyo, zinokuncitshiswa ngokupheleleyo ngokukhupha iiyunithi zokupholisa kunye ne-air-conditioning units. Ubutofotofo bangaphakathi. I-evaporation kunye ne-conditioning air-conditioning units zohlulwe zibe ziindidi ezimbini: ukubanda kwangaphakathi kunye nokubanda kwangaphandle. Kwindawo yomswakama ophakathi kunye neendawo zokufuma okuphezulu, ukudibanisa ukufudumala kunye nokupholisa kunye nefriji yomatshini idla ngokusetyenziswa. Umzekelo, iholo lequla lokuqubha lisebenzisa indlela yokukhupha umoya wokupholisa kunye nefriji yomatshini edityaniswe neyunithi yokupholisa umoya kwizihlalo zokuhlala.
(3) Umphunga womoya-amanzi kunye nokupholisa kunye nenkqubo yokupholisa umoya-moya, olwenziwa ngokunyuka kwamanzi kunye nokupholisa iiyunithi zomoya omtsha ukuze kuqhutywe umoya omtsha kunye nomthwalo wobushushu obunokubakho kunye nomthwalo wobushushu obungaphelelanga kwi-ofisi ye-gymnasium kunye negumbi elincedisayo. Inxalenye yamanzi abandayo ingathunyelwa kwi-evaporation kunye nokupholisa iyunithi yomoya omtsha (ukubanda kwangaphandle), kwaye enye inxalenye ingathunyelwa ngokuthe ngqo kumthwalo wokushisa kwiofisi kunye negumbi elincedisayo.
