Kuhambo lwam lokusebenza nezixhobo ezahlukeneyo zemozulu kunye neenkqubo, iiprobe zomswakama beziyinxalenye eqhelekileyo yezixhobo zam. Ezi zixhobo, ezisetyenziselwa ukulinganisa umswakama ohambelanayo, zidlala indima ebalulekileyo kumacandelo ahlukeneyo, ukusuka kwiinkqubo zemozulu kunye ne-HVAC ukuya kulondolozo lobugcisa kunye nokusetyenziswa kwezolimo. Umswakama ohambelanayo (RH), obonisa ubungakanani bomswakama obukhoyo emoyeni xa kuthelekiswa nobuninzi obunokububamba kubushushu obuthile, yiparameter ebalulekileyo kwezi ndawo. Umlinganiselo ochanekileyo unokwenza umahluko omkhulu ekugcineni iimeko ezifanelekileyo zenkqubo okanye kwanokuqikelela iipateni zemozulu.
Ukubaluleka kokufundwa kwe-RH kundenze ndachitha ixesha elininzi ndifunda kwaye ndisebenza ngee-humidity probes. Kuyo yonke amava am, ndifumanise ukuba ezi zixhobo, nangona zinobuchule kakhulu, azisoloko zingenasiphako ekufundeni kwazo. Njengazo naziphi na ezinye izixhobo zokulinganisa, zifuna ukuphathwa ngononophelo, ukulinganiswa rhoqo, kunye nokuqonda ngokucacileyo imigaqo kunye nemida yazo. Joyina nam njengoko sijonga kwihlabathi le-humidity probes kwaye sifumanise ukuba zinokuchaneka kangakanani xa kufikwa ekulinganiseni i-RH.
Ukuqonda Indlela Iiprobes Zokufuma Ezisebenza Ngayo
Ukuze kuhlolwe ukuchaneka kweiiprobe zokufuma, ndifumanise ukuba kubalulekile ukuqonda imigaqo esisiseko sokusebenza kwazo. Uninzi lwezinzwa zokufuma zisebenzisa iindlela zokuqhuba ubushushu ezikwaziyo ukukhupha umoya, ezikwaziyo ukumelana nobushushu, okanye ezisebenzisa ubushushu ukuze zibone utshintsho kumswakama womoya. Apha, ndiza kugxila kakhulu kwiiprobe ezikwaziyo ukukhupha umoya, eziphakathi kwezona zisetyenziswa kakhulu ngenxa yobuntununtunu bazo obuhle, uzinzo lwexesha elide, kunye nokuchasana nongcoliseko.
