Kana iyo screw firiji unit yatangwa, chinhu chekutanga kuziva ndechekuti firiji system iri kushanda zvakajairika. Iyi inotevera sumo pfupi yezviri mukati uye zviratidzo zvenguva dzose kushanda, uye zvinotevera ndezvekutarisa chete:
Mvura inotonhorera ye condenser inofanira kunge yakakwana, kudzvinyirira kwemvura kunofanira kunge kuri pamusoro pe 0.12MPa, uye tembiricha yemvura haifanire kunge yakanyanya kukwirira.
Kune screw firiji mayunitsi, kuverenga kwepombi yemafuta ekumanikidza geji kunofanirwa kunge kuri 0.15 ~ 0.3MPa yakakwira kupfuura iyo yekupopotera.
Chero mamiriro ezvinhu, tembiricha yemafuta haifanire kudarika 70°C yefluorine refrigeration unit uye 65°C yemafiriji ammonia, uye shoma haifanire kunge yakaderera pane 30°C. Pasi pemamiriro ekushanda, mafuta ekuzora haafaniri kuputira (kunze kwefluorine refrigeration unit).
Refrigeration unit discharge tembiricha. Ammonia neR22 hazvipfuuri 135 ° C, uye kana kupisa kwegesi kwemhepo kuchikwira mberi, ichava duku zvikuru kana ichienzaniswa nemoto wefiriji yemafuta (160 ° C), iyo isina kunaka kune midziyo. Nokudaro, kubva pakuona kwekushandiswa, kupisa kwekupisa hakufaniri kunge kwakanyanyisa, uye kana kwakanyanyisa, kunofanira kumira kuti uwane chikonzero.
The level of condensing pressure. Inonyanya kusarudzwa maererano nemvura, chimiro che condenser uye refrigerant inoshandiswa. Iyo yemvura nhanho yedhiza haizove yakaderera kupfuura chikamu chimwe muzvitatu chechiratidzo chemvura, uye chiyero chemafuta checrankcase hachifanirwe kuderera pane yakatwasuka yepakati mutsara wechiratidzo chehwindo.
Iyo otomatiki inodzosa pombi yemafuta efluorine separator yakajairika kana kuchitonhora uye kuchipisa, uye kutonhora nekupisa kutenderera kungangoita 1 awa. Hapafanirwe kuve nekusiyana kwekushisa kuri pachena pamberi uye mushure mesefa yepombi yemvura. Hapafanirwe kuve nechando, zvikasadaro ichavharika. Fluorine firiji inofanira kutonhorera padivi rakatsetseka uye inopisa kune yakaoma. Majoini eiyo fluorine system haifanire kudonha mafuta, zvinoreva kuti fluorine kubuda.
Paunenge uchibata horizontal condenser panguva yekushanda, chikamu chepamusoro chinofanira kunge chichipisa uye chikamu chepasi chinofanira kutonhora. Kusangana kwekutonhora nekupisa ndiyo refrigerant fluid level. Kuparadzanisa mafuta kunopisawo kumusoro, uye chikamu chezasi hachina kupisa zvakanyanya. Ivhavhavha yekudzivirira kana kuti bypass valve yefiriji inofanira kunzwa inotonhorera pamucheto wakaderera, kana isina kutonhora, zvinoreva kuti yakakwirira uye yakaderera mhepo inoputika.
Panguva yekushanda, mhepo yemhepo inofanira kufanana neyokusveta, uye kupera kwemhepo kumucheto wepamusoro-soro kunofanira kunge kwakafanana nekudzvinyirira uye kudzvinyirira kwemvura inogamuchira. Kana zvisina kudaro, hazvina kujairika.
Pasi peimwe mwero wekuyerera kwemvura, panofanirwa kuve nemusiyano wetembiricha pakati pekupinda nekubuda kwemvura inotonhorera. Kana pasina mutsauko wetembiricha kana mutsauko mudiki wetembiricha, zvinoreva kuti nzvimbo yekupisa yekupisa yemidziyo yekutsinhanisa kupisa yakasviba uye inoda kuvharwa pakuchenesa.
Iyo firiji pachayo inofanira kuvharwa uye haifanire kudonhedza refrigerant uye mafuta ekuzora. Kune shaft chisimbiso, kana iyo yakajairwa kutonhora simba iri 12.6 × 1000 kJ/h, shaft chisimbiso chinotenderwa kuve nemafuta mashoma ekudonha, uye firiji ine yakajairwa kutonhora kugona> 12.6 × 1000 kJ/h haibvumirwe kuve isingapfuure gumi madonhwe emafuta ekudonha, iyo shaori yefiriji yeawa haifanirwe kuve neawa inoyerera mafuta anodonha.
Kupisa kwechisimbiso cheshaft uye kutakura kwefiriji hakufaniri kudarika 70 ° C.
Frost kana dova pavharuvhu yekuwedzera yakafanana, asi chando chakakora hachifanire kuoneka painopinza.
