Ke molao-motheo o ka sehloohong oa ho sehatsetsi tloaelehile 'me tsamaiso ea refrigeration eng?

lefatše la kajeno ho thata ho nahana ntle le seo a se finyeletseng ea tsoela pele ea saense le ea theknoloji le ntshetsopele ea tsoelo-pele. Thanks ho tse sibolotsoeng saense batho ba ne ba fumaneha mefuta e sa tšoaneng ea matla hore ba rue molemo botho kajeno. E mong oa breakthroughs tsena e ne e le ho qaptjoa mechine ea refrigeration unit trust ka 1910, ho French fisiks Marcel Odifrenom.

Molao-motheo oa tšebetso ea sehatsetsi e thehiloeng lipono tse makatsang tsa meleng condensation 'me e le mouoane, e leng e bontšoa ka tsela e latelang: tsamaiso mocheso pompo refrigeration fetisetsa mocheso matla a ka kamoreng e ka sebetsa ho ka ntle ho, moo e pholisa le e matahoa a sa itlhompheng ka tikoloho. The khase Cooling eo sebetsang sebakeng sa hae e le freon, hexafluoride sebabole, ammonia, kapa o phethahatsa tshebetso pitikololo, eo ho eona a batang hlahisoang.

Ho fihlela ka tshebetso e phahameng tsidifatso hlokahala sebakeng seo se seholo sa futhumatsang le Cooling mocheso exchanger ho ba khona ho theha khatello e phahameng. tsamaiso ea refrigeration morao-rao e hase kamehla ho loketseng, kahoo mona e le hore a finyelle hlokahalang khatello ea sebelisoa compressors hore compress le di-pump refrigerant mouoane, ka tsela eo e ntseng e eketseha, e seng feela khatello empa hape thempereichara setsidifatsi ena. Kahoo, molao-motheo oa tšebetso ea ho tsamaiso ea refrigeration e thehiloe melao ea motheo ea fisiks.

Refrigeration compressors ke ea mefuta e latelang:

- nsete;

- Piston;

- centrifugal mofuta.

Ea bobeli ke atlehang ka ho fetisisa le ho pharaletseng sebelisoa ka tsamaiso ea morao-rao refrigeration bakeng sa tšebeliso liindasteri. Ho phaella moo, ka sehatsetsing efe kapa efe 'me leqhoa ea sehatsetsi hakaalo akarelletsa capacitor e reretsoe ho sokolla ho mouoane ka mokelikeli ka ntlha ya go liphetoho ka mocheso ambient.

Ka kakaretso, sehatsetsi molao-motheo o sebetsa e sa feela sebelisoa ho hlahisa refrigeration merero tse sa tšoaneng, empa tsamaiso ea leqhoa a, ho tloha ka ho fetola khatello ea tsamaisong ea ka fumana mocheso o lakatsa ka hare tikoloho kamoreng. Ha konpresser ho fetisa refrigerant tlas'a khatello e phahameng ka ho sa bose khethehileng le kena vaporization kamoreng, moo sephetho le e bohale fokotseha mokelikeli hang-hang fetoloa khatello ea mouoane. Ena ketsahalo meleng refrigerant le ka lebaka la ho thepa lona ho nka mocheso maboteng evaporator, sephetho le ka tsidifatso butle-butle ka kamoreng e ka hare ea unit trust refrigeration.

Molao-motheo oa tšebetso ea sehatsetsi le 'nile la sebelisoa ka lilemo tse fetang 100 lilemong,' me selemo le selemo ho na le ho feta a macha le ntlafala tlhomamiso. E mong oa tse qapiloeng morao-rao lefapheng lena e bile ho hlaha ha diyuniti thermoelectric refrigeration hore sebelisa Peltier molao-motheo. phello ea e thehiloeng ketsahalo e sa mocheso phapang ea mahareng ka ha jwale phallang, oo ka oona ho ka etsahala ho fihlela ho fokotsa mocheso ka hare tsa sebaka refrigeration tikoloho. Ho sa tsotellehe 'nete ea hore o ile a ithuta ka nako e telele fetileng sibolla thepa ea morao-rao ea motlakase, ho fihlela morao tjena ho atile joalo mabenkeleng a batang ba ne ba sa fumana. Hangata ba sebelisoa ka likoloi lihatsetsi, coolers le metsi a nooang batang mokotla, empa ka lebaka la litšenyehelo tse phahameng tsa thermoelectric morero oa likarolo tsidifatso ho fihlela morao tjena ne a sa lekaneng disseminated.

Morao-rao bohato sehatsetsi molao-motheo o ne a tla lumella ho sebelisa refrigerating liindasteri le diyuniti freezing ho indasteri e lijo, hammoho le a polokelo a batang setsing le polokelo dihlahiswa. Ho thata ho feteletsa bohlokoa ba ho sibolloa ea molao oa bobeli oa thermodynamics, hobane ntle e ka ba ho le thata ho kenya tshebetsong mesebetsi eohle ea limela morao-rao e lokisa lijo. Kahoo, molao-motheo oa tšebetso ea sehatsetsi kajeno ralile motheo oa tsamaiso ea morao-rao tsidifatso ea merero ea bobeli indasteri le e ruuoang.
