Indima yezingxenye eziyinhloko zesomisi esiqandisiwe
1. I-compressor yesiqandisi
Ama-compressor ayisiqandisi ayinhliziyo yesistimu yesiqandisi, futhi ama-compressor amaningi namuhla asebenzisa ama-compressor e-hermetic reciprocating.Ukuphakamisa isiqandisi kusukela phansi kuya kokucindezela okukhulu nokuzungeza isiqandisi ngokuqhubekayo, isistimu ngokuqhubekayo ikhipha ukushisa kwangaphakathi endaweni engaphezu kwezinga lokushisa lesistimu.
2. I-Condenser
Umsebenzi we-condenser ukupholisa umfutho ophezulu, umhwamuko oshisa kakhulu oyisiqandisi okhishwa i-compressor yesiqandisi ungene esiqandisini esiwuketshezi, futhi ukushisa kwawo kususwa amanzi okupholisa.Lokhu kuvumela inqubo yesiqandisi ukuthi iqhubeke ngokuqhubekayo.
3. I-Evaporator
I-evaporator iyisakhi esiyinhloko sokushintshanisa ukushisa kwesomisi esiqandisi, futhi umoya ocindezelwe upholiswa ngenkani ku-evaporator, futhi umhwamuko omningi wamanzi uyapholiswa futhi ufihlwe emanzini awuketshezi futhi ukhishwe ngaphandle komshini, ukuze umoya ocindezelwe wome. .Uketshezi lwesiqandisi olunomfutho ophansi luba umhwamuko onengcindezi ephansi yesiqandisi ngesikhathi soshintsho lwesigaba ku-evaporator, lumunce ukushisa okuzungezile phakathi noshintsho lwesigaba, ngaleyo ndlela lupholise umoya ocindezelwe.
4. I-valve yokwandisa i-Thermostatic (i-capillary)
I-valve yokwandisa i-thermostatic (i-capillary) iyindlela yokuphefumula yesistimu yesiqandisi.Esiqandisini esomisayo, ukunikezwa kwesiqandisi se-evaporator kanye nesilawuli saso sitholwa nge-throttling mechanism.I-throttling mechanism ivumela isiqandisi ukuthi singene ku-evaporator kusuka kuketshezi olushisa kakhulu kanye nomfutho ophezulu.
5. Umshini wokushisa
Ingxenye enkulu yezomisa iziqandisi inesishintshi sokushisa, okuyisishintshi sokushisa esishintshanisa ukushisa phakathi komoya nomoya, ngokuvamile isishintshi sokushisa esingamashubhu (esaziwa nangokuthi igobolondo nesishintshi sokushisa seshubhu).Umsebenzi oyinhloko wesishintshi sokushisa endaweni yokomisa isiqandisi “ukubuyisela” amandla okupholisa athwalwa umoya ocindezelwe ngemva kokupholiswa yi-evaporator, futhi usebenzise le ngxenye yomthamo wokupholisa ukupholisa umoya ocindezelwe ezingeni eliphezulu lokushisa umhwamuko omkhulu wamanzi (okungukuthi, umoya ocindezelwe ogcwele okhishwa ku-compressor yomoya, upholiswe isipholile sangemuva se-compressor yomoya, bese uhlukaniswa nomoya namanzi ngokuvamile ungaphezu kuka-40 °C), ngaleyo ndlela kunciphisa umthwalo wokushisisa uhlelo lwesiqandisi nokomisa kanye nokufeza inhloso yokonga amandla.Ngakolunye uhlangothi, izinga lokushisa lomoya ocindezelwe osezingeni eliphansi ku-exchanger lokushisa liyabuyiselwa, ukuze udonga lwangaphandle lwepayipi elihambisa umoya ocindezelwe lungabangeli into "yokufingqa" ngenxa yezinga lokushisa elingaphansi kwezinga lokushisa elizungezile.Ukwengeza, ngemva kokukhuphuka kokushisa komoya ocindezelweyo, umswakama ohlobene komoya ocindezelwe ngemva kokumiswa uyancishiswa (ngokuvamile ungaphansi kuka-20%), okuzuzisa ukuvimbela ukugqwala kwensimbi.Abanye abasebenzisi (isb. abanezitshalo zokuhlukanisa umoya) badinga umoya ocindezelwe onomswakama ophansi kanye nezinga lokushisa eliphansi, ngakho umshini wokomisa iziqandisi asisahlomeki ngesishintshi sokushisa.Njengoba isishintshi sokushisa singafakiwe, umoya obandayo awukwazi ukuphinda usetshenziswe, futhi umthwalo wokushisa we-evaporator uzokhula kakhulu.Kulesi simo, amandla we-compressor yesiqandisi akudingeki nje kuphela ukuthi anyuswe ukuze ahlawulele amandla, kodwa futhi nezinye izingxenye zesistimu yonke yesiqandisi (i-evaporator, i-condenser kanye ne-throttling components) idinga ukwandiswa ngokufanele.Ngokombono wokuthola amandla, sihlala sithemba ukuthi ukuphakama kokushisa kwe-exhaust dryer, kungcono (izinga lokushisa eliphezulu lokukhipha amandla, elibonisa ukubuyiswa kwamandla amaningi), futhi kungcono kakhulu ukuthi akukho umehluko wokushisa phakathi kwe-inlet ne-outlet.Kodwa empeleni, akunakwenzeka ukufeza lokhu, lapho izinga lokushisa lokungenisa umoya lingaphansi kuka-45 °C, akuvamile ukuthi izinga lokushisa lokungena nokuphuma kwe-dryer dryer lihluke ngaphezu kuka-15 °C.
Ukucubungula Umoya Ocindezelwe
Umoya ocindezelwe → izihlungi eziyimishini→ izishintshisi zokushisa (ukukhipha ukushisa), →izihwamuzi→ izihlukanisi zegesi-uketshezi→ izishintshisi zokushisa (ukumunca ukushisa), → izihlungi eziyimishini eziphumayo→ amathangi okugcina igesi
Ukunakekela nokuhlola: gcina izinga lokushisa elisezingeni lamazolo le-dryer dryer ngaphezu kweziro.
Ukunciphisa izinga lokushisa lomoya ocindezelweyo, izinga lokushisa lokuhwamuka kwesiqandisi kufanele libe phansi kakhulu.Lapho umshini wokomisa isiqandisi upholisa umoya ocindezelwe, kuba nongqimba lwe-condensate efana nefilimu ebusweni bophiko lwe-evaporator liner, uma izinga lokushisa elingaphezulu le-fin lingaphansi kwe-zero ngenxa yokuncipha kwezinga lokushisa lokuhwamuka, indawo engaphezulu. I-condensate ingaba yiqhwa, ngalesi sikhathi:
A. Ngenxa yokunamathiselwe kwengqimba yeqhwa ene-thermal conductivity encane kakhulu ebusweni be-evaporator yesinye sangaphakathi, ukusebenza kahle kokushintshisana kokushisa kuncipha kakhulu, umoya ocindezelwe awukwazi ukupholiswa ngokuphelele, futhi ngenxa ukumuncwa ukushisa okunganele, izinga lokushisa lokuhwamuka kwesiqandisi lingancishiswa ngokwengeziwe, futhi umphumela womjikelezo onjalo nakanjani uzoletha imiphumela eminingi emibi ohlelweni lwesiqandisi (njengokuthi "ukucindezela uketshezi");
B. Ngenxa yezikhala ezincane phakathi kwamaphiko ku-evaporator, lapho amaphiko eqhwa, indawo yokujikeleza komoya ocindezelwe izoncishiswa, futhi ngisho nendlela yomoya izovinjelwa ezimweni ezinzima, okungukuthi, "ukuvinjelwa kweqhwa";Kafushane, izinga lokushisa elicindezelayo endaweni yokomisa isiqandisi kufanele libe ngaphezu kuka-0 °C, ukuze kuvikelwe izinga lokushisa lezinga lamazolo ukuba lingabi phansi kakhulu, isomisi sesiqandisi sinikezwa ukuvikelwa kwe-bypass yamandla (okutholwe yi-bypass valve noma i-fluorine solenoid valve. ).Lapho izinga lokushisa lendawo yamazolo lingaphansi kuka-0 °C, i-valve yokudlula (noma i-fluorine solenoid valve) ivuleka ngokuzenzakalelayo (indawo yokuvula iyanda), futhi isitimu esiqandisi esingancindezelwanga nesinomfutho ophezulu we-high-pressure esiqandisini sijovwa ngokuqondile ekungeneni kwe-evaporator. (noma ithangi lokuhlukanisa uketshezi lwegesi endaweni yokufaka i-compressor), ukuze izinga lokushisa lendawo yamazolo likhuphuke libe ngaphezu kuka-0 °C.
C. Ngokombono wokusetshenziswa kwamandla esistimu, izinga lokushisa lokuhwamuka liphansi kakhulu, okuholela ekwehleni okukhulu kwe-coefficient yesiqandisi se-compressor kanye nokwanda kokusetshenziswa kwamandla.
Hlola

2.3 Ngemva kokuba isomisi sisebenze imizuzu engu-3-5, qala ngokuvula kancane kancane i-valve yomoya ongenisayo, bese uvula ivalvu yomoya yokuphuma ngokuvumelana nesilinganiso somthwalo kuze kugcwale umthwalo.
2.4 Hlola ukuthi izikali zomoya ongenisayo neziphumayo zijwayelekile yini (umehluko phakathi kokufundwa kwamamitha amabili ka-0.03Mpa kufanele ube ojwayelekile).
2.5 Hlola ukuthi ukugeleza kwamanzi okuzenzakalelayo kujwayelekile yini;
2.6 Hlola izimo zokusebenza zesomisi njalo, rekhoda i-air inlet ne-outlet pressure, ingcindezi ephezulu nephansi yamalahle abandayo, njll.
3 Inqubo yokuvala;
3.1 Vala i-valve yokukhipha umoya;
3.2 Vala i-valve yokungenisa umoya;
3.3 Cindezela inkinobho yokumisa.
4 Izinyathelo zokuqapha
4.1 Gwema ukugijima isikhathi eside ngaphandle komthwalo.
4.2 Ungawuqalisi ngokuqhubekayo i-compressor yesiqandisi, futhi inani leziqalo nezitobhi ngehora akumele libe likhulu kunezikhathi eziyisi-6.
4.3 Ukuze uqinisekise izinga lokuhlinzekwa kwegesi, qiniseka ukuthi uthobela umyalelo wokuqala nokumiswa.
4.3.1 Qala: Vumela isomisi sisebenze imizuzu engu-3-5 ngaphambi kokuvula i-compressor yomoya noma i-valve yokungena.
4.3.2 Ukuvala shaqa: Vala i-compressor yomoya noma i-valve yokuphumayo kuqala bese uvala umshini wokomisa.
4.4 Kunamavalvu e-bypass kunethiwekhi yephayiphi anwebeka endaweni yokungena nokuphuma kwesomiso, futhi ivalvu yokudlula kufanele ivalwe ngokuqinile ngesikhathi sokusebenza ukuze kugwenywe umoya ongahlanzekile ongena kunethiwekhi yamapayipi omoya angezansi komfula.
