Lub Npe Lub Npe: Sab Hauv Tsev Huab Cua Zoo (IAQ) Kev Ntsuas ntawm Beijing Qiqi Kindergarten
Txhawm rau ua kom pom cov neeg siv khoom muaj txiaj ntsig los ntawm kev siv peb lub tshuab ua pa rov qab, peb tau ua qhov ntsuas huab cua sab hauv tsev hauv Beijing Qiqi Kindergarten.
Cov cuab yeej tshuaj xyuas thiab cov khoom siv: Plua plav tester (T-H48), ozone analyzer (T-IAQ46), carbon dioxide gas detector (T-KZ79), ntsuas kub thiab av noo (T-IAQ17), lub thawv khoob barometer (H60), steel daim kab xev Kev ntsuas (T-H29)
Cov khoom soj ntsuam:PM25, ozone, carbon dioxide
1. Txheej txheem cej luam
Cov kev ntsuam xyuas tau ua tiav hauv Beijing Qiyao Kindergarten, uas nyob ntawm No. 2, Qingboyuan, Lancangchang East Road, Haidian District, Beijing.Txhawm rau muab cov tub ntxhais kawm nrog qhov chaw kawm zoo, Beijing Qiqi Kindergarten qhia Holtop ntsug lub zog rov qab lub tshuab ua pa kom muaj cua huv thiab huv.Lub zog ntsug rov qab lub tshuab ua pa tau nruab rau hauv qee chav kawm (Tuam Tshoj: Beijing HOLTOP Cua Conditioning Co., Ltd., qauv: ERVQ-L600-1A1).Peb tau tso cai rau peb txoj cai, Lub Chaw Saib Xyuas Kev Tswj Xyuas Kev Tswj Xyuas Kev Tswj Xyuas Kev Tswj Xyuas Kev Tswj Xyuas thiab Kev Tshawb Fawb Hauv Tebchaws, los tshuaj xyuas PM2.5, ozone thiab carbon dioxide concentrations hauv qee chav kawm ntawm Beijing Qiyao Kindergarten thaum lub Tsib Hlis 14, 2019.
2. Kev soj ntsuam xyuas
Cov kev ntsuam xyuas tau ua nyob rau hauv Chav A, qhov PM2.5 sab hauv tsev, ozone thiab carbon dioxide concentration tau sim ua ntej tig lub zog ntsug rov qab lub tshuab ua pa, tom qab ntawd lub tsev tau qhib thiab hloov kho rau cov kev ua haujlwm tau teev tseg (lub vijtsam qhia tau tias khiav ntawm lub tshuab ua pa. ceev tshaj plaws).Tom qab ua haujlwm rau 1 teev, PM25 sab hauv tsev, Ozone thiab carbon dioxide concentrations tau sim dua.Qhov loj ntawm chav kawm yog 7.7mx 1m x 9m.Thaum lub sijhawm xeem, muaj 3 tus neeg laus (pojniam), 12 tus menyuam yaus (6 tus tub thiab 6 tus ntxhais), lub qhov rais kaw, thiab lub qhov rooj qhib dawb.
3. Cov qhabnias xeem
Table 1: Sab Hauv Tsev Cov Tshuaj Ntsuam Xyuas Cov Khoom Ua Ntej Ua ntej qhib Holtop Energy Recovery Ventilator
| Qauv txoj hauj lwm | PM2.5 (mg / m3) | Ozone (mg / m3) | Cov pa roj carbon dioxide (%) |
| Chav Kawm A | 0.198 ib | 0.026 ib | 0.12 |
| Sab nraum zoov | 0.298 ib | 0.046 ib | 0.04 ib |
Table 2 Kev soj ntsuam cov pa phem hauv tsev tom qab 1 teev ntawm kev ua haujlwm tas li ntawm Holtop Energy Recovery Ventilator
| Qauv txoj hauj lwm | PM2.5 (mg / m3) | Ozone (mg / m3) | Cov pa roj carbon dioxide (%) |
| Chav Kawm A | 0.029 ib | 0.027 ib | 0.09 ib |
| Sab nraum zoov | 0.298 ib | 0.046 ib | 0.04 ib |
Lus Cim: Thaum lub sij hawm sim, lub qhov hluav taws xob muab hluav taws xob ntawm lub tshuab hluav taws xob ntsug rov qab tau qhib thaum lub qhov hluav taws xob sab saud kaw.
Raws li peb tuaj yeem pom cov txiaj ntsig tau hais tias tom qab siv peb lub tshuab ua pa rov qab, PM2.5 thiab carbon dioxide tuaj yeem txo qis thiab txhim kho huab cua sab hauv tsev.
