Chigadziko chefiriji chikamu chakakosha chekuchengetedza zvinhu zvinotonhora. Hunhu hwechigadziko chefiriji hunokanganisa zvakananga kana tembiricha iri muchigadziko ichi ichikwanisa kusvika nekuchengetedza tembiricha yakatarwa uye kana tembiricha yacho isingachinji.
Kune mhando dzakawanda dzemafiriji. Mafiriji makuru akawanda anochengetera zvinhu zvinotonhora zvishoma anofarira kushandisa masikuruu akaenzana. Ndezvipi zvakanakira?
1. Hunhu hwacho hwakagadzikana uye ruzha rwakaderera kana tichienzanisa nezvimwe zvigadzirwa zvakafanana.
2. Kushanda kwakanyanya. Kunyangwe kana compressor yekufiriji ikatadza kushanda, hazvizokanganisi mashandiro esystem yese yekufiriji.
3. Kune misanganiswa yakawanda yesimba rekutonhodza. Huwandu hwekutenga kana kushanduka kwekushisa kwekunze kwenzvimbo huru dzekuchengetera zvinhu zvinotonhora zvishoma dzimwe nguva kwakakura, uye screw parallel units dzinogona kuwana chiyero chiri nani chesimba rekutonhodza.
4. Mutoro wekushanda wecompressor imwe chete muyuniti i25%, uye inogona kuva 50%, 75%, uye kutonga kwesimba. Inogona kuenzana nekukwanisa kutonhora kunodiwa mukushanda kwazvino kusvika padanho guru, izvo zvinoshanda zvakanyanya uye zvinochengetedza simba.
5. Compressor ine chimiro chakareruka uye chidiki, ine simba rekudzvanya zvakanyanya, uye inoshanda zvakanyanya pakutonhodza.
6. Mapaipi nemavharuvhu akaenzana anoiswa pakati pemasisitimu maviri akazvimiririra. Kana zvikamu zvemuchina wefriji necondenser zvikakundikana, imwe sisitimu inogona kuramba ichishanda zvakanaka.
7. Chigadzirwa ichi chinodzora mabasa ePLC ekutonga nekuratidza.
Chigadzirwa che "screw parallel unit" chiri nani ne "evaporative condenser" nekuti chinogona kuwana tembiricha yakaderera yekudzikamisa, zvichivandudza mashandiro e "firming", uye kugona kwe "firming" kunogona kuwedzerwa neinenge 25% zvichienzaniswa ne "air-cooled condenser"; uye mashandiro nekuchengetedza zviri nyore uye zvinodhura, uye hupenyu hwekushanda hwakareba.
Kune zvinhu zvakawanda zvakachengetwa munzvimbo huru dzinotonhorera dzine tembiricha yakaderera. Kana firiji ikakundikana uye basa rekutonhodza rikamira, kurasikirwa kwacho kunopfuura kwenzvimbo diki inotonhorera. Saka, pakusarudza nzvimbo yekutonhodza, nzvimbo huru dzinotonhorera dzinofunga nezvezvikamu zvakafanana. Kunyangwe imwe yecompressor yekutonhodza ikakundikana, hazvizokanganisi sisitimu yese yekutonhodza.
