Izakhiwo zezemidlalo zineempawu zendawo enkulu, inkqubela phambili enzulu, 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) Evaporate air-conditioning inkqubo yokupholisa umoya, oko kukuthi, ngaphandle umoya omtsha umphunga umoya -conditioner ukuhlanjululwa kunye nonyango lokupholisa, kwaye uyithumele kwigumbi emva kokuhlanjululwa komoya omdaka wangaphakathi uze ukhuphe ngqo ngaphandle.

(2) Yonke inkqubo yokupholisa umoya iba ngumphunga kunye neyokungenisa umoya. Phakathi kwazo, kwiindawo ezomileyo, zinokuncitshiswa ngokupheleleyo ngokukhupha iiyunithi zokupholisa kunye ne-air-conditioning units. Ubutofotofo bangaphakathi. Iiyunithi zokupholisa umoya zokupholisa umoya zahlulwe zibe ziindidi ezimbini: ukubanda kwangaphakathi nangaphandle. Kwindawo yomswakama ophakathi kunye neendawo eziphezulu zokufuma, 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 Inxalenye yamanzi abandayo ingathunyelwa kwi-evaporation kunye nokupholisa iyunithi yomoya omtsha (ibanda yangaphandle), kwaye enye inxalenye ingathunyelwa ngokuthe ngqo kubushushu-ubushushu obucacileyo bomthwalo kwiofisi kunye negumbi elincedisayo.
