Ndezvipi zvinowanzodiwa zvekushanda kwemafiriji?
Ndezvipi zvinowanzodiwa zvekushanda kwemafiriji?
Kana iyo chiller ichigona kushanda zvakajairika uye zvakachengeteka, firiji inokosha. Isvikiro rinoshanda rinotenderera mu chiller refrigeration system kuti riwane firiji, uye inonziwo refrigeration working medium kana refrigerant. Saka, ndezvipi zvinowanzoitika zvinodiwa zvefiriji kune inotonhorera yeakasiyana mafiriji kutenderera?
1. Thermodynamic properties [plating chiller]
1. Inofanira kuva ine mwero wakazara saturated steam pressure. Evaporating pressure haifanire kunge yakadzikira pane yeatmospheric pressure kudzivirira kubuda kwemhepo musystem (tora screw chiller/air-cooled chiller/water-cooled chiller semuenzaniso); iyo condensing pressure haifaniri kunge yakanyanya kukwirira, kana zvisina kudaro kudzvinyirira kudiwa kwegadziriro kuchakanganiswa. Kuwedzera, uye kuchawedzera kushandiswa kwesimba; uyezve, chiyero che condensing pressure kune evaporating pressure haifanire kunge yakanyanya kukwirira, zvikasadaro zvinokonzeresa tembiricha yekuyerera kwecompressor ye chiller kukwira.
2. Inofanirwa kunge iine tembiricha yakanyanya kuoma (kupfuura tembiricha yepakati), kuitira kuti igone kunyungudika patembiricha yekamuri kana tembiricha yakaderera, uye kurasikirwa kwekukwenya kuchaderedzwa.
3. Inofanira kuva nekushisa kwakadzika kwekusimbisa. Izvi zvinodzivirira mufiriji kubva kuchando pamhepo inoputika.
4. Inofanira kuva nepamusoro-soro conductivity. Izvi zvinogona kuwedzera kuchinjisa kupisa kweiyo yekupisa yekupisa yechiller (tora screw chiller / air-cooled chiller / mvura-yakatonhorera chiller semuenzaniso), kuderedza kupisa kwenzvimbo, uye kuderedza kugadzira uye kushandisa mari.
5. Panofanira kuva nediki adiabatic index. Izvi zvinogona kuita kuti maitiro ekumanikidza apedze simba shoma, uye tembiricha yekuburitsa compressor haizove yakanyanya kukwirira.
6. Iyo chaiyo inopisa simba refiriji mvura idiki. Izvi zvinogona kuderedza throttling process kurasikirwa.
2. Kuita kwemuviri nemakemikari [air-cooled chiller]
1. Inofanira kuva nediki diki uye viscosity, iyo inogona kuderedza kuyerera kwekudzivirira kurasikirwa kwefiriji mu unit unit refrigeration system (tora screw chiller / air-cooled chiller / water-cooled chiller semuenzaniso).
2. Inodiwa kuti ive isingabatiki, inoputika, isina-chepfu, uye isiri nyore kuparara pasi pekushisa kwepamusoro, uye kwete nyore kukanganisa zvikamu zvesimbi zvechiller.
