1.6.2 Tsanangudzo uye chikwata chekudzivirira hunyoro
Moisture resistance: kuyerera kwekupisa kwekubuda mumhepo kuburikidza neimwe nzvimbo pasi pemamiriro emvura yakagadzikana mhute pressure gradient.
Iyo mwando inopikisa unit Ret iri muPascal pa watt pa square mita (m2·Pa/W).
Iyo ndiro yekuyedza uye ndiro yekudzivirira ese ari maviri simbi yakakosha porous mahwendefa, ayo akafukidzwa nefirimu rakatetepa (rinogona kungopinda mumhute wemvura asi kwete mvura yemvura).Pasi pekupisa kwemagetsi, kutonhora kwemvura yakasvibiswa inopiwa nehurongwa hwemvura inokwira kusvika kune yakatarwa kukosha (yakadai se35 ℃).Bhodhi rekuedza uye bhodhi rayo rekudzivirira rakapoteredzwa uye ndiro yepasi zvese zvinochengetwa patembiricha imwechete (senge 35 ° C) nemagetsi ekudziya ekudzora, uye tembiricha sensor inoendesa iyo data kune yekudzora system kuchengetedza tembiricha isingaperi.Naizvozvo, iyo mhute yemvura inopisa simba remuenzaniso bhodhi inogona chete kukwira kumusoro (mune nzira yemuenzaniso).Iko hakuna mhute yemvura uye kuchinjana kwekupisa kune dzimwe nzira,
bhodhi rekuedza uye bhodhi rayo rekudzivirira rakapoteredzwa uye ndiro yepasi zvose zvinochengetwa patembiricha imwe chete (yakadai se35 ° C) kuburikidza nekupisa kwemagetsi, uye tembiricha yekushisa inotumira data kune hurongwa hwekutonga kuchengetedza kupisa nguva dzose.Iyo mhute yemvura inopisa simba reiyo sampuli ndiro inogona kungodzingwa kumusoro (munzira yemuenzaniso).Iko hakuna mvura mhute kupisa simba kuchinjanisa mune dzimwe nzira.Tembiricha iri pa15mm pamusoro pemuenzaniso inodzorwa pa35 ℃, hunyoro hwehukama i40%, uye yakachinjika kumhanya kwemhepo i1m/s.Iyo yakaderera pamusoro pefirimu ine saturated mvura kudzvinyirirwa kwe5620 Pa pa 35 ℃, uye pamusoro peiyo sample ine kudzvanywa kwemvura kwe2250 Pa pa35 ℃ uye hunyoro hunoenderana ne40%.Mushure mekunge mamiriro ebvunzo agadzikana, sisitimu inozozvionera yega simba rekudziya rinodiwa kuti test board ichengetedze tembiricha isingaperi.
Ukoshi hwekudzivirira hunyoro hwakaenzana nekudzivirira kunyorova kwesample (15mm mhepo, test board, sample) kubvisa hunyoro hwekudzivirira kwebhodhi risina chinhu (15mm mhepo, test board).

1.7 Chiridzwa chimiro
Chiridzwa chacho chinoumbwa nezvikamu zvitatu: muchina mukuru, microclimate system, kuratidza uye kutonga.
1.7.1Muviri mukuru wakashongedzerwa nendiro yekuenzanisira, ndiro yekudzivirira, uye ndiro yepasi.Uye imwe neimwe yekudziya ndiro inopatsanurwa nekupisa insulating zvinhu kuti ive nechokwadi chekuti hapana kutamisa kupisa pakati peumwe neumwe.Kuti udzivirire sampuli kubva kumhepo yakapoteredza, chivharo che microclimate chinoiswa.Iko kune yakajeka organic girazi gonhi pamusoro, uye tembiricha uye humidity sensor yekamuri yekuyedza yakaiswa pachivharo.
1.7.2 Kuratidza uye kudzivirira system
Chiridzwa chinotora weinview touch inoratidzira yakabatanidzwa skrini, uye inodzora iyo microclimate system uye bvunzo host kuti ishande uye kumira nekubata mabhatani anoenderana pachiratidziro chekuratidzira, data yekudzora yekupinza, uye yekubuda bvunzo yemaitiro uye mhedzisiro.
1.8 Hunhu hwezviridzwa
1.8.1 Yakaderera kudzokorora kukanganisa
Iyo yepakati chikamu cheYYT255 iyo yekudziya yekudzora system chishandiso chakakosha chakazvimiririra kutsvagirwa uye kugadzirwa.Theoretically, inobvisa kusagadzikana kwemhedzisiro yebvunzo inokonzerwa ne thermal inertia.Iyi tekinoroji inoita kuti chikanganiso cheyedzo inodzokororwa ive idiki kwazvo pane yakakodzera zviyero kumba nekune dzimwe nyika.Mazhinji e "heat transfer performance" bvunzo zviridzwa zvine chikanganiso chekudzokorora chingangoita ± 5%, uye kambani yedu yasvika ± 2%.Zvinogona kutaurwa kuti yakagadzirisa dambudziko renyika refu remhosho huru dzekudzokorora mumidziyo yekupisa yekupisa uye yakasvika padanho repasi rose..
1.8.2 Chimiro chakasimba uye kutendeseka kwakasimba
Iyo YYT255 chishandiso chinobatanidza mugamuchiri uye microclimate.Inogona kushandiswa yakazvimirira pasina chero ekunze zvishandiso.Inochinjika kune zvakatipoteredza uye yakanyatso kugadziridzwa kuderedza kushandiswa kwemamiriro.
1.8.3 Kuratidza nguva chaiyo ye "thermal and humidity resistance" kukosha
Mushure mokunge sampu yafanopisa kusvika kumagumo, iyo yose "kupisa kwekushisa uye unyoro kuramba" kukosha kwekudzikamisa maitiro kunogona kuratidzwa munguva chaiyo.Izvi zvinogadzirisa dambudziko renguva refu yekupisa nekunyorova kuedza kuedza uye kusakwanisa kunzwisisa maitiro ese.
1.8.4 Yakanyanya kuyedzerwa ganda-kudikitira maitiro
Iyo chiridzwa ine yakakwira simulation yeganda remunhu (yakavanzwa) dikita mhedzisiro, iyo yakasiyana neiyo test board ine mashoma mashoma maburi.Iyo inogutsa kuenzana kwemhute yemvura kwese kwese pabhodhi rekuyedza, uye nzvimbo yekuyedza inoshanda ndeyechokwadi, kuitira kuti iyo yakayerwa "munyoro kuramba" iri pedyo chaiyo kukosha.
1.8.5 Multi-point yakazvimirira calibration
Nekuda kwehukuru hukuru hwekupisa uye hunyoro kuramba kuyedzwa, akawanda-poinzi akazvimirira calibration anogona zvinobudirira kuvandudza chikanganiso chinokonzerwa nekusagadzikana uye kuve nechokwadi chechokwadi chebvunzo.
1.8.6 Microclimate tembiricha uye humidity inopindirana neyakajairwa control point
Kuenzaniswa nezviridzwa zvakafanana, kutora tembiricha yemicroclimate uye humidity inoenderana neyakajairwa yekudzora poindi inowirirana ne "method standard", uye zvinodiwa zve microclimate control zvakakwirira.
