Igama leProjekthi: Uvavanyo loMgangatho woMoya waNgaphakathi (IAQ) lwe-Beijing Qiqi Kindergarten
Ukuze ubonise umthengi iziphumo ngokusebenzisa ii-ventilators zethu zokubuyisela amandla, senze uvavanyo lomgangatho womoya wangaphakathi eBeijing Qiqi Kindergarten.
Izixhobo zokuhlola kunye nezixhobo: Umvavanyi wothuli (T-H48), i-ozone analyzer (T-IAQ46), i-carbon dioxide gas detector (T-KZ79), imitha yobushushu kunye nokufuma (T-IAQ17), i-barometer yebhokisi engenanto (H60) , iteyiphu yensimbi umlinganiselo (T-H29)
Izinto zokuhlola: I-PM25, i-ozone, i-carbon dioxide
1. Isishwankathelo
Uvavanyo lwenziwa eBeijing Qiyao Kindergarten, efumaneka kwiNombolo yesi-2, iQingboyuan, iLancangchang East Road, iSithili saseHaidian, eBeijing. Ukuze kubonelelwe abafundi ngendawo yokufunda ekumgangatho ophezulu, iBeijing Qiqi Kindergarten yazisa iHoltop ethe nkqo yokubuyisela umoya wokubuyisela amandla ukubonelela ngomoya ococekileyo nococekileyo. Ii-ventilators zokubuyisela amandla ezithe nkqo zafakwa kumagumbi athile okufundela (Umvelisi: Beijing HOLTOP Air Conditioning Co., Ltd., imodeli: ERVQ-L600-1A1). Siphathise igunya lesithathu, iZiko leSizwe lokuJonga nokuHlola uMgangatho weSixhobo soMoya weSizwe, ukuba lihlole i-PM2.5 yangaphakathi, i-ozone kunye necarbon dioxide kumagumbi okufundela e-Beijing Qiyao Kindergarten ngoMeyi 14, 2019.
2. Imiqathango yoHlolo
Iimvavanyo zenziwa kwiKlasi A, i-PM2.5 yangaphakathi, i-ozone kunye ne-carbon dioxide concentration yavavanywa phambi kokuba kulayishwe i-ventilator yokubuyisela amandla ethe nkqo, emva koko iyunithi ibivuliwe kwaye ilungelelaniswe neemeko zokusebenza ezichaziweyo (isikrini sibonisa ukusebenza isantya esiphezulu). Emva kokubaleka iyure ye-1, i-PM25 yangaphakathi, i-Ozone kunye ne-carbon dioxide concentrations yavavanywa kwakhona. Ubungakanani begumbi lokufundela yi-7.7mx 1m x 9m. Ebudeni bovavanyo, bekukho abantu abadala aba-3 (abafazi), abantwana abayi-12 (amakhwenkwe ama-6 kunye namantombazana ama-6), ifestile yayivaliwe, kwaye umnyango wawukhululekile ukuba uvule.
3. Iziphumo zovavanyo
Itheyibhile 1: Iziphumo zoHlolo oluNgcolisekileyo lwaNgaphakathi phambi koKuvulwa kweHoltop yokuBuyisela aMandla oMbane
| Indawo yesampuli | PM2.5 (mg/m3) | Iozone (mg/m3) | Umoya omdaka (%) |
| Iklasi A | 0.198 | 0.026 | 0.12 |
| Ngaphandle | 0.298 | 0.046 | 0.04 |
Itheyibhile 2 iziphumo zokuhlola ungcoliseko lwangaphakathi emva kweyure enye yokusebenza ngokuqhubekayo kweHoltop Energy Recovery Ventilator.
| Indawo yesampuli | PM2.5 (mg/m3) | Iozone (mg/m3) | Umoya omdaka (%) |
| Iklasi A | 0.029 | 0.027 | 0.09 |
| Ngaphandle | 0.298 | 0.046 | 0.04 |
Amagqabantshintshi: Ngexesha lovavanyo, indawo yokuphuma komoya ye-ventilanti ethe nkqo yokubuyisela amandla iyavulwa ngelixa indawo yomoya ephezulu ivaliwe.
Njengoko sinokubona iziphumo zokuba emva kokusebenza kwe-ventilator yethu yokubuyisela amandla, i-PM2.5 kunye ne-carbon dioxide inokunciphisa kakhulu kwaye iphucule umgangatho womoya wangaphakathi.
