Ndezvipi zvikonzero zvakakosha zvekumanikidza kuneta kupisa?

Izvo zvikonzero zvikuru zvekupisa kweiyo yekupisa gasi tembiricha ndeinotevera: yakakwira kudzoka mweya tembiricha, hombe kudziyisa kugona kwemotokari, yakakwira compression ratio, yakakwira condensation kumanikidza, uye isina kukodzera firiji sarudzo.

High kudzoka mhepo tembiricha

Iyo yekudzoresa mweya tembiricha inoenderana neyekupisa tembiricha. Kuti udzivise kudzoka kwemvura, iyo yekudzosa mweya pombi inowanzo inoda kudzoka mweya superheat ye20 ° C. Kana iyo yekudzosera mhepo pombi isina kunyatso kusungirirwa, iyo superheat inodarika 20 ° C.

Iyo yakakwira iyo yekudzosa mweya tembiricha, iyo yakakwira iyo humburumbira yekukwevera tembiricha uye pedza tembiricha. Nguva dzese tembiricha yekudzoka yemhepo painowedzera ne1 ° C, tembiricha yekupedza ichawedzera ne1 kusvika 1.3 ° C.

Kupisa mota

Kune iyo yekudzosa-mhepo kutonhora compressor, iyo firiji furi inopisa nemota sezvo ichiyerera nepakati pemota mhango, uye iyo humburumbira yekuyamwa tembiricha yakawedzerwazve. Iko kukosha kwecalorific yemota kunokanganiswa nemasimba uye nekugona, uye iko kushandiswa kwesimba kwakabatana zvakanyanya nekushanduka, volumetric kugona, mashandiro ezvinhu, kusagadzikana kusagadzikana, nezvimwe.

Mukudzoka kwemhepo inotonhorera mhando semi-hermetic compressor, iyo tembiricha inomuka yeiyo firiji mune mota mhango iri pakati pe15 ne45 ° C. Mumhepo-yakadzikama (mhepo-yakadzikama) compressor, iyo firiji system haina kupfuura nemumhepo, saka hapana chinetso chekupisa mota.

Compression ratio yakanyanya kukwirira

Tembiricha yekupedza inokanganiswa zvakanyanya neiyo compression ratio. Iyo yakakura iyo compression ratio, iyo inowedzera iyo yekupedza tembiricha. Kuderedza kuyerwa kwecompression kunogona kudzikisira tembiricha yekupedza. Dzakanangana nzira dzinosanganisira kuwedzera kukweva kumanikidza uye kudzikisa yekumanikidza kumanikidza.

Iko kumanikidza kwekumanikidza kunoonekwa neiyo evaporation yekumanikidza uye kushorwa kwepombi yekukweva. Kuwedzera kwemhepo tembiricha kunogona kunyatso kuwedzera kumanikidza kwekumanikidza uye nekukurumidza kudzikisira chiyero chekumanikidza, nokudaro ichideredza kupisa kwetambo.

Vamwe vashandisi vakasarudzika kuti vatende kuti iyo yakadzika iyo tembiricha yekumhanyisa, ndiyo inokurumidza iyo inotonhora mwero. Iyi pfungwa ine matambudziko mazhinji. Kunyange kudzikisa kwemvura tembiricha kunogona kuwedzera kutonhora tembiricha mutsauko, iyo firiji kugona kweiyo compressor kwaderedzwa, saka kutonhora kumhanyisa hakusi iko kukurumidza. Chii zvakare, iyo yakadzika kudzika kwekusimuka kwemhepo, yakaderera iyo firiji coefficient, asi mutoro unowedzera, iyo yekushandisa nguva inowedzerwa, uye simba rekushandisa rinowedzera.

Kuderedza kusagadzikana kwetambo yekudzoka yemhepo kunogona zvakare kuwedzera kudzoka kwemhepo mweya. Idzo nzira dzakasarudzika dzinosanganisira kutsividza panguva yakakodzera iyo yakasviba yekudzosa mweya firita, uye kudzikamisa hurefu hwepombi yekushanduka nemhepo yekudzoka. Uye zvakare, isina kukwana firiji zvakare chinhu chekudzikira kwekumanikidza kumanikidza. Iyo firiji inofanira kuzadzikiswa munguva mushure mekunge yarasika. Kudzidzira kunoratidza kuti kudzikisira iyo tembiricha yekupedza nekuwedzera iyo yekumanikidza kumanikidza kuri nyore uye kunoshanda kupfuura dzimwe nzira.

Chikonzero chikuru cheiyo yakanyanya kukwirira yekumanikidza kumanikidza ndeyekuti iyo yekudzora yekumanikidza yakanyanya kukwirira. Iyo isina kukwana kupisa nzvimbo yekudzora yeiyo condenser, kusvibisa, kukwana kukwana kutonhora mweya vhoriyamu kana mvura vhoriyamu, yakanyanya kutonhora mvura kana tembiricha yemhepo, nezvimwe zvinogona kukonzera kunyanyisa kudzikisira kumanikidza. Izvo zvakakosha kuti usarudze yakakodzera condensing nzvimbo uye chengetedza yakakwana inotonhora yepakati kuyerera kuyerera.

Iyo yepamusoro-tembiricha uye mweya-kutonhodza compressor dhizaini ine yakaderera yekushanda compression ratio. Mushure mekushandisirwa firiji, iyo compression reshiyo yakapetwa kaviri, tembiricha yekudzimisa yakanyanya kwazvo, uye kutonhora hakugone kuenderera, zvichikonzera kupisa. Naizvozvo, zvinodikanwa kuti usashandise kushandiswa kwepamusoro-soro kweiyo compressor uye kuita kuti iyo compressor ishande pane yakaderera inogoneka yekumanikidza. Mune mamwe masisitimu ekudziya epasi, kupisa zvakanyanya ndiko kunonyanya kukonzera compressor kutadza.

Anti-kuwedzera uye gasi kusanganisa

Mushure mekutanga kwekukweva sitiroko, iyo yakanyanya-kumanikidza gasi yakavharirwa muchibvumirano chesilinda ichaita anti-yekuwedzera maitiro. Mushure mekuwedzeredza kuwedzera, iro gasi kumanikidza rinodzokera pakumanikidza, uye simba rinodyiwa rekumanikidza chikamu chegasi rakarasika mukuwedzeredza kuwedzera. Iwo madiki kubvumidzwa, madiki mashandisiro esimba anokonzerwa nekupokana-nekuwedzera kune rumwe rutivi, uye akakurisa iwo mweya unodyiwa kune rimwe divi, izvo zvinowedzera zvakanyanya chiyero chesimba remagetsi che compressor.

Munguva yeanopokana-nekuwedzera maitiro, gasi rinobata yakakwira tembiricha pamusoro peiyo vharafu ndiro, pamusoro pepistoni uye pamusoro pesilinda yekupisa kupisa, saka tembiricha yegasi haizodonhe kune yekutsvaira tembiricha pakupera kweiyo anti-kuwedzera.

Mushure mekunge anti-kuwedzera kwapera, iyo inhalation maitiro anotanga. Mushure mekunge gasi rapinda musirinda, kune rumwe rutivi, inosanganiswa neye-anti-kuwedzera gasi uye tembiricha inokwira; kune rimwe divi, iyo yakavhenganiswa gasi inotora kupisa kubva kumadziro kuwedzera tembiricha. Naizvozvo, iyo tembiricha yegasi pakutanga kwekumanikidza maitiro yakakwira kupfuura tembiricha yekukweva. Nekudaro, sezvo iyo yekudzoreredza yekuwedzera maitiro uye yekuyamwa maitiro ari mapfupi, iyo chaiyo tembiricha inokwira ishoma kwazvo, kazhinji iri pasi pe5 ° C.

Anti-kuwedzera kunokonzerwa nesirinda clearance, iri kukundikana kusingadzivisike kwechinyakare pisitoni compressors. Kana iyo gasi iri mugomba rekubuditsa revhavha yevhavha isingakwanise kuburitswa, pachave nekurwisa-kuwedzera.

Kumanikidza tembiricha kukwira uye firiji mhando

Mafriji akasiyana ane akasiyana ekushisa uye epanyama zvimiro, uye iyo yekuzadza tembiricha inokwira zvakasiyana mushure meiyo imwecheteyo yekumanikidza maitiro. Naizvozvo, mafiriji akasiyana siyana anofanirwa kusarudzwa kune akasiyana tembiricha tembiricha.

mhedziso uye zano:

Iyo compressor haifanire kuve neanopisa kupisa zviitiko senge tembiricha yakakwira yemota uye yakanyanyisa kukwirira chiutsi tembiricha mune yakajairika mashandiro e compressor. Compressor overheating yakakosha chiratidzo chiratidzo, zvichiratidza kuti pane dambudziko rakakomba mufiriji system, kana iyo compressor inoshandiswa uye inochengetwa zvisizvo.

Kana iyo sosi ye compressor yakanyanyisa kupisa iri mufiriji system, dambudziko rinogona kugadziriswa chete nekuvandudza dhizaini uye kugadzirisa kweiyo firiji system. Kuchinjira kune nyowani compressor hakugone kubvisa dambudziko rinopisa zvakanyanya.
