Zvikonzero zvikuru zvekupisa kwekushisa kwecompressor exhaust tembiricha ndezvizvi: tembiricha yekudzoka kwemhepo, hombe yekudziya kwemota, yakakwira compression ratio, yakakwira condensation pressure, uye isina kufanira kusarudzwa kwefiriji.
1. Dzorera tembiricha yemhepo
Iyo tembiricha yemhepo inodzoka inoenderana nekupisa kwemhepo. Kuti udzivise kuyerera kwemvura kumashure, pombi dzemhepo dzekudzokera dzinowanzoda kudzoka kwemhepo yakanyanya kupisa ye20°C. Kana pombi yemhepo yekudzoka isina kuvharirwa zvakanaka, kupisa kwakanyanya kunodarika 20°C.
Iyo yakakwirira tembiricha yemhepo inodzoka, ndipo pakakwirira kukweva silinda uye tembiricha yekuburitsa. Kune yega yega 1 ° C kuwedzera kwekudzoka tembiricha yemhepo, tembiricha yekubuda inokwira.
2. Motokari kupisa
Kudzoreredza kutonhora kwemhepo compressors, iyo refrigerant mhute inopiswa nemota kana ichiyerera nepakati pemota mhango, uye tembiricha yekudhonza silinda inowedzerwa zvakare.
Kupisa kunogadzirwa nemota kunokanganisa simba uye kushanda zvakanaka, nepo mashandisirwo emagetsi ari padhuze nekutamisa, volumetric kunyatsoita, mamiriro ekushanda, friction kuramba, nezvimwe.
Kudzoreredza mhepo inotonhorera semi-hermetic compressors, tembiricha inokwira yefiriji mumotor cavity inotangira pa15°C kusvika 45°C. Mumhepo-yakatonhorera (air-cooled) compressors, firiji system haipfuuri nemhepo, saka hapana dambudziko rekupisa motokari.
3. The compression reshiyo yakanyanya
Iyo tembiricha yekubuda inokanganiswa zvakanyanya neiyo compression ratio. Iyo yakakura iyo compression reshiyo, inowedzera tembiricha yekuburitsa. Kudzikisira reshiyo yekumanikidza kunogona kuderedza zvakanyanya tembiricha yekupedza nekuwedzera kusveta kudzvanywa uye kudzikisa exhaust pressure.
Kusveta kudzvanywa kunotarirwa ne evaporation pressure uye suction line resistance. Kuwedzera tembiricha yekubuda kwemhepo kunogona kuwedzera kusveta kudzvanywa, nekukurumidza kuderedza iyo compression reshiyo, uye nekudaro kuderedza tembiricha yekubuda.
Kudzidzira kunoratidza kuti kudzikisa tembiricha yekubuda nekuwedzera kusvetwa kuri nyore uye kunoshanda kupfuura dzimwe nzira.
Chikonzero chikuru chekunyanyisa kupera simba ndechekuti iyo condensation pressure yakanyanya. Kusakwana kutonhora nzvimbo ye condenser, chiyero kuunganidza, kusakwana kutonhora kutonhora vhoriyamu kana vhoriyamu yemvura, yakanyanya kutonhora mvura kana tembiricha yemhepo, nezvimwe zvinogona kutungamirira kune yakawandisa condensation pressure. Izvo zvakakosha kuti usarudze iyo yakakodzera condensation nzvimbo uye kuchengetedza zvakakwana kutonhora kwepakati kuyerera.
Iyo yepamusoro-tembiricha uye air-conditioning compressors akagadzirirwa kushanda ane yakaderera compression reshiyo. Mushure mekushandiswa kwefiriji, iyo compression reshiyo inowedzera exponentially, tembiricha yekubuda yakakwira zvakanyanya, uye kutonhora hakugone kuenderera, zvichikonzera kupisa. Naizvozvo, dzivisa kushandisa compressor kupfuura huwandu hwayo uye shandisa iyo compressor pazasi peiyo shoma inogoneka yekumanikidza reshiyo. Mune mamwe ma cryogenic system, kupisa kwakanyanya ndicho chikonzero chikuru chekutadza kwe compressor.
4. Anti-kuwedzera uye gasi kusanganiswa
Mushure mekunge kusveta kunotanga, gasi repamusoro-soro rakavharirwa muhumburumbira rekuchenesa richaita de-expansion process. Mushure mekuwedzera-kuwedzerwa, gasi rekumanikidza rinodzokera kune kusveta kudzvinyirira, uye simba rinoshandiswa kumanikidza chikamu ichi chegasi rinorasika panguva yekuwedzera. Iyo diki yemvumo, iyo diki yekushandiswa kwesimba kunokonzerwa ne-anti-kuwedzera kune rumwe rutivi, uye yakakura vhoriyamu yekusveta kune rumwe rutivi, nokudaro zvakanyanya kuwedzera simba rekuita reshiyo ye compressor.
Munguva ye-de-expansion process, gasi rinobata nzvimbo dzepamusoro-tembiricha yeplate yevharuvhu, piston kumusoro uye silinda pamusoro kuti itore kupisa, saka tembiricha yegesi haizodonhedze kusvika pakudziya kwekudhonza pakupera kwekuwedzera.
Mushure mokunge anti-expansion yapera, inhalation process inotanga. Mushure mokunge gasi inopinda muhumburumbira, kune rumwe rutivi inosanganiswa ne-anti-expansion gas uye kutonhora kunokwira; kune rumwe rutivi, gasi rakasanganiswa rinotora kupisa kubva pamadziro uye rinopisa. Naizvozvo, tembiricha yegesi pakutanga kwekumanikidza kwakakwira kupfuura kupisa kwekudhonza. Zvisinei, sezvo maitiro ekubvisa-kuwedzera uye maitiro ekusveta ari mapfupi, tembiricha chaiyo inokwira ishoma, kazhinji isingasviki 5°C.
Anti-kuwedzera kunokonzerwa necylinder clearance uye kukanganisa kusingadzivisike kwechinyakare piston compressors. Kana gasi riri mugomba revhavha yevhavha risingakwanisi kubudiswa, pachava nekuwedzera kwemashure.
5. Compression tembiricha kukwira uye refrigerant mhando
Mafiriji akasiyana ane akasiyana thermophysical zvimiro, uye tembiricha yekubuda gasi inokwira zvakasiyana mushure mekuita maitiro akafanana ekumanikidza. Nokudaro, nokuda kwekushisa kwakasiyana kwefiriji, mafiriji akasiyana anofanira kusarudzwa.
6. Mhedziso uye mazano
Kana iyo compressor ichishanda zvakajairwa mukati mechikamu chekushandiswa, hapafanirwe kuve nekuwedzeredza zviitiko senge yakakwira mota tembiricha uye yakanyanya kupisa tembiricha yemhepo. Compressor overheating chiratidzo chakakosha chinokanganisa, zvichiratidza kuti pane dambudziko rakakura mufiriji system, kana kuti compressor haina kushandiswa uye inochengetwa.
Kana iyo midzi ye compressor overheating iri mufiriji system, dambudziko rinogona kugadziriswa chete nekuvandudza dhizaini nekuchengetedza firiji system. Kutsiva compressor nyowani hakugone kubvisa zvachose dambudziko rekupisa.
