IZINDABA ZESIKHATHI SANGEMPELAizindaba

Ukwandisa ushintsho lwesihlungi konga imali namuhla — futhi kungaphula buthule isithembiso sekhwalithi yomoya wangaphakathi esabekwa yisikhungo sakho esiteji sokuklama. Nansi indlela yokulinganisela kokubili ngaphandle kokugembula ekuthobeleni imithetho.

Umhlahlandlela womphathi wesikhungo wokuqonda i-ASHRAE 52.2 MERV-A kanye ne-ISO 16890 ePM1 — ngoba ukukhetha isabelomali sokuthobela imithetho engalungile kanye nokusebenza kwe-IAQ.

Ngavakashela isikhungo sedatha eJakarta ngo-2022 esasibhekene nokwehluleka okuqhubekayo kwe-hard drive emgqeni owodwa wama-server racks — ukwehluleka okune ezinyangeni eziyisithupha, konke endaweni efanayo, konke ku-hardware efanayo.Umphathi wesikhungo wayeshintshe ama-drive, wahlola ikhwalithi yamandla, futhi wabuyekeza i-firmware.

Umphathi wokuthenga ovela enkampanini yemithi eShenzhen wake wangishayela ucingo wathi, 'Ngidinga izihlungi ze-HEPA zegumbi lami lokuhlanza'. Lapho ngibuza ukuthi yiliphi ibanga, wathi, 'I-HEPA nje, uhlobo olujwayelekile.'Inkinga iwukuthi, alukho 'uhlobo olujwayelekile' lwe-HEPA — okungenani kunezigaba eziyisikhombisa ezihlukene ngaphansi kwezindinganiso zomhlaba wonke, kusukela ekusebenzeni kahle okungu-99.95% kuya ku-99.999995%, futhi umehluko phakathi kwazo unganquma ukuthi igumbi lakho lokuhlanza liyaphumelela yini ekuhlolweni kwe-EU GMP noma liyahluleka.

Ukufaka izihlungi zomoya ze-HVAC zezentengiselwano ngesheduli yekhalenda ehleliwe kuyindlela ebiza kakhulu yokuphatha uhlelo lokuhlunga - futhi ngibonile ukuthi kubiza abaphathi bezikhungo amashumi ezinkulungwane zamaRandi minyaka yonke. Uchungechunge lwamahhotela eSingapore lwake lwangitshela ngokuziqhenya ukuthi bashintsha zonke izihlungi “njalo ezinyangeni ezintathu njengokusebenza kwewashi.” Bangitshengise incwadi yabo yokubhalisa — izindawo zokuhlunga ezingu-400, izindawo zokushintsha ezingu-1,600 ngonyaka, imali echithwa ngonyaka engu-$19,200.

Bengilokhu ngakha izihlungi zomoya kwa-KWS kusukela ngo-2011, futhi ukungaqondi kahle okukodwa engikuthola kubathengi ukucabanga ukuthi "ngcono" kusho "ukusebenzisa izinga eliphezulu yonke indawo."Umphathi wesikhungo eMalaysia wake wa-oda izihlungi ze-HEPA zesakhiwo sakhe sonke sehhovisi ngoba wayefuna "umoya ohlanzekile kakhulu." Wasebenzisa u-$38,000 ezihlungini, wazifaka ngaphandle kokuzihlunga kusengaphambili, futhi kwadingeka ashintshe yonke iyunithi ye-HEPA zingakapheli izinyanga ezine ngoba zazigcwele uthuli olukhulu olwalungamiswa yi-pre-filter ye-$5 G4.

Ngivakashele izimboni zokucubungula ukudla ezingaphezu kuka-40 kulo lonke elaseShayina, eNingizimu-mpumalanga ye-Asia, kanye naseMpumalanga Ephakathi selokhu ngajoyina i-KWS ngo-2011,futhi ngingakutshela ngokuqiniseka ukuthi inguquko eyodwa enganakwa kakhulu ekuphepheni kokudla umoya. Abaphathi bezitshalo bagxila kakhulu kumashejuli okuhlanzeka komhlaba, ukuhlolwa kwabahlinzeki bezinto zokusetshenziswa, kanye nokulawulwa kwezinga lokushisa - futhi kufanele. Kodwa umoya ohamba endaweni yabo awuvamile ukuhlolwa ngendlela efanayo.

Angisoze ngalukhohlwa ucingo engaluthola kumphathi wesikhungo eDubai ngo-2019.Uhlelo lwakhe lwe-HVAC lwalusebenzisa amandla angaphezu kuka-35% kunonyaka odlule, amandla akhe okupholisa ayehla, futhi ithimba lakhe lokulungisa lase lishintshe ama-compressor amabili. Akekho owayengathola ukuthi kungani.

Uma wake wazama ukuqhathanisa isihlungi somoya esivela kumhlinzeki waseYurophu nesinye esivela kumkhiqizi waseNyakatho Melika,uhlangabezane nokukhungatheka kwezinhlelo zokulinganisa ezingalingani.
