Indima yezingxenye eziyinhloko zomshini wokomisa oqandisiwe

1. I-compressor yesiqandisi

Ama-compressor esiqandisini ayinhliziyo yesistimu yokuqandisa, futhi ama-compressor amaningi namuhla asebenzisa ama-compressor aphindaphindayo angenawo umoya. Ukuphakamisa i-refrigerant kusuka ekucindezelweni okuphansi kuya kokuphezulu futhi kujikelezise i-refrigerant njalo, uhlelo luqhubeka nokukhipha ukushisa kwangaphakathi endaweni engaphezu kwezinga lokushisa lesistimu.

2. I-Condenser

Umsebenzi we-condenser ukupholisa umhwamuko we-refrigerant ocindezelwe kakhulu, oshiswa kakhulu okhishwa yi-refrigerant compressor uye efrijini eliwuketshezi, bese ukushisa kwawo kususwa ngamanzi apholile. Lokhu kuvumela inqubo yokuqandisa ukuthi iqhubeke njalo.

3. Isihwamukisi

I-evaporator iyisakhi esiyinhloko sokushintshanisa ukushisa kwe-friji dryer, futhi umoya ocindezelwe upholiswa ngenkani ku-evaporator, futhi iningi lomhwamuko wamanzi liyapholiswa bese lifakwa emanzini acwebezelayo bese likhishwa ngaphandle komshini, ukuze umoya ocindezelwe wome. Uketshezi lwe-refrigerant olunomfutho ophansi luba umhwamuko we-refrigerant ophansi ngesikhathi sokushintsha kwesigaba ku-evaporator, lumunce ukushisa okuzungezile ngesikhathi sokushintsha kwesigaba, ngaleyo ndlela lupholise umoya ocindezelwe.

4. I-valve yokwandisa i-thermostatic (i-capillary)

I-valve yokwandisa i-thermostatic (i-capillary) iyindlela yokubopha uhlelo lokuqandisa. Kumshini wokomisa oqandisayo, ukuhlinzekwa kwesiqandisi se-evaporator kanye nomlawuli waso kutholakala ngokusebenzisa indlela yokubopha. Indlela yokubopha ivumela isiqandisi ukuthi singene ku-evaporator sisuka kuketshezi olushisa kakhulu nolunomfutho ophezulu.

5. Isishintshi sokushisa

Iningi lama-dryer omisa iziqandisi line-heat exchanger, okuyi-heat exchanger eshintshanisa ukushisa phakathi komoya nomoya, ngokuvamile i-tubular heat exchanger (eyaziwa nangokuthi i-shell and tube heat exchanger). Umsebenzi oyinhloko we-heat exchanger ku-friji dryer "ukubuyisela" amandla okupholisa athwalwa umoya ocindezelwe ngemva kokuphola yi-evaporator, bese usebenzisa le ngxenye yamandla okupholisa ukupholisa umoya ocindezelwe ekushiseni okuphezulu ophethe inani elikhulu lomhwamuko wamanzi (okungukuthi, umoya ocindezelwe ogcwele okhishwa ku-air compressor, opholishwe yi-cooler yangemuva ye-air compressor, bese uhlukaniswa umoya namanzi ngokuvamile ungaphezu kuka-40 °C), ngaleyo ndlela kunciphisa umthwalo wokushisa wesistimu ye-friji nokomisa futhi kufezwe inhloso yokonga amandla. Ngakolunye uhlangothi, izinga lokushisa lomoya ocindezelwe ophansi ku-heat exchanger liyabuyiswa, ukuze udonga lwangaphandle lwepayipi elithutha umoya ocindezelwe lungabangeli "ukufinyela" ngenxa yokushisa okungaphansi kwezinga lokushisa elizungezile. Ngaphezu kwalokho, ngemva kokwenyuka kwezinga lokushisa lomoya ocindezelwe, umswakama womoya ocindezelwe ngemva kokomiswa uyancishiswa (ngokuvamile ungaphansi kuka-20%), okuzuzisa ukuvimbela ukugqwala kwensimbi. Abanye abasebenzisi (isb. ngezitshalo zokuhlukanisa umoya) badinga umoya ocindezelwe onomswakama ophansi kanye nokushisa okuphansi, ngakho-ke umshini wokomisa oqandisayo awusafakelwe umshini wokomisa. Njengoba umshini wokomisa oshisayo ungafakiwe, umoya obandayo awukwazi ukuphinda usetshenziswe, futhi umthwalo wokushisa we-evaporator uzokhula kakhulu. Kulesi simo, akudingi nje kuphela ukuthi amandla e-compressor yokuqandisa akhuliswe ukuze kunxeshezelwe amandla, kodwa futhi nezinye izingxenye zesistimu yonke yokuqandisa (i-evaporator, i-condenser kanye nezingxenye ze-throttling) zidinga ukukhushulwa ngokufanele. Ngokombono wokubuyiselwa kwamandla, sihlala sinethemba lokuthi lapho izinga lokushisa lokukhipha umoya le-evaporator yokuqandisa liphezulu, kungcono (izinga lokushisa eliphezulu lokukhipha umoya, okubonisa ukubuyiselwa kwamandla amaningi), futhi kungcono ukuthi kungabikho umehluko wokushisa phakathi kokungena kanye nokukhipha. Kodwa empeleni, akunakwenzeka ukufeza lokhu, lapho izinga lokushisa lokungena komoya lingaphansi kuka-45 °C, akuvamile ukuthi izinga lokushisa lokungena nelokuphuma komshini wokomisa iziqandisi lihluke ngaphezu kuka-15 °C.

Ukucubungula Umoya Okucindezelwe

Umoya ocindezelwe→ izihlungi zemishini→ izishintshi zokushisa (ukukhishwa kokushisa), →izihwamuki→ izihlukanisi zegesi noketshezi → izishintshi zokushisa (ukumuncwa kokushisa), → izihlungi zemishini zokukhipha → amathangi okugcina igesi

Ukugcinwa nokuhlolwa: gcina izinga lokushisa lamazolo emshini wokomisa isiqandisi lingaphezu kwezinga-zero.

Ukuze kuncishiswe izinga lokushisa lomoya ocindezelwe, izinga lokushisa lokuhwamuka kwe-refrigerant kumele libe phansi kakhulu. Lapho umshini wokomisa isiqandisi upholisa umoya ocindezelwe, kuba nongqimba lwe-condensate efana nefilimu ebusweni bephiko le-evaporator liner, uma izinga lokushisa lobuso bephiko lingaphansi kwezinga ngenxa yokwehla kwezinga lokushisa lokuhwamuka, i-condensate yobuso ingase iqine, ngalesi sikhathi:

A. Ngenxa yokunamathela kwengqimba yeqhwa enokushisa okuncane kakhulu ebusweni bephiko langaphakathi lesinye se-evaporator, ukusebenza kahle kokushintshana kokushisa kuncipha kakhulu, umoya ocindezelwe awukwazi ukuphola ngokuphelele, futhi ngenxa yokumuncwa okwanele kokushisa, izinga lokushisa lokuhwamuka kwesiqandisi lingancishiswa kakhulu, futhi umphumela womjikelezo onjalo ngokuqinisekile uzoletha imiphumela eminingi emibi ohlelweni lwesiqandisi (njengokucindezelwa koketshezi");

B. Ngenxa yesikhala esincane phakathi kwamaphiko ku-evaporator, uma amaphiko eqandisiwe, indawo yokujikeleza komoya ocindezelwe izoncishiswa, futhi ngisho nendlela yomoya izovinjelwa ezimweni ezimbi kakhulu, okungukuthi, "ukuvinjelwa kweqhwa"; Ngamafuphi, izinga lokushisa le-compression dew point ye-friji dryer kufanele libe ngaphezu kuka-0 °C, ukuze kuvinjelwe izinga lokushisa le-dew point lingabi phansi kakhulu, i-friji dryer inikezwa isivikelo se-energy bypass (esifinyelelwa yi-bypass valve noma i-fluorine solenoid valve). Lapho izinga lokushisa le-dew point liphansi kuka-0 °C, i-bypass valve (noma i-fluorine solenoid valve) ivuleka ngokuzenzakalelayo (ukuvulwa kuyanda), futhi umusi obandayo ongavundisiwe wokushisa okuphezulu kanye nomfutho ophezulu ufakwa ngqo ku-evaporator (noma ithangi lokuhlukanisa igesi noketshezi ku-compressor inlet), ukuze izinga lokushisa le-dew point liphakanyiswe libe ngaphezu kuka-0 °C.

C. Ngokombono wokusetshenziswa kwamandla ohlelweni, izinga lokushisa lokuhwamuka liphansi kakhulu, okuholela ekwehleni okukhulu kwe-coefficient yokuqandisa i-compressor kanye nokwanda kokusetshenziswa kwamandla.
