Ungayixazulula kanjani inkinga yokungabuyi kahle kukawoyela we-screw chiller?

Kunezindlela ezimbili zokubuyisa uwoyela ku-compressor, enye ukubuyisa uwoyela wokwahlukanisa uwoyela, enye ukubuya kukawoyela wepayipi lokubuyisa umoya. Isihlukanisi sikawoyela sifakwe kwipayipi le-compressor qeda. Ngokuvamile, u-50-95% wamafutha angahlukaniswa. Umphumela wokubuyiswa kukawoyela muhle, ijubane liyashesha, futhi nenani lamafutha angena kupayipi lesistimu ancishiswe kakhulu, ngaleyo ndlela kwandise ukusebenza ngempumelelo ngaphandle kokubuyiselwa kukawoyela. isikhathi.

Akuyona into engavamile ngezinhlelo zokubanda ezigcina amakhaza ezinamapayipi amade ngokwedlulele, amasistimu okwenza uketshezi agcwele, nemishini yokumisa iqhwa ngamazinga okushisa aphansi kakhulu ukubuyisa ngaphezu kwemizuzu eyishumi noma ngisho nemizuzu eminingana ngemuva kokuqala, noma ngokuncane kakhulu ukubuya kukawoyela. Idizayini Uhlelo olubi luzodala ukuthi i-compressor ime ngenxa yengcindezi kawoyela ophansi. Ukufakwa kwesihlukanisi sophethiloli esisebenza kahle kakhulu ohlelweni lwefriji kungandisa isikhathi sokusebenza esingabuyisi se-compressor, ukuze i-compressor idlule ngokuphepha esigabeni senhlekelele sokungabuyiswa kukawoyela ngemuva kokuqala. .

Amafutha okugcoba angahlukanisiwe azongena ohlelweni bese egeleza nesiqandisi esisesipayipini ukwakha ukujikeleza kukawoyela. Ngemuva kokuthi uwoyela wokuthambisa ungene ku-evaporator, ingxenye kawoyela othambisayo uhlukaniswa nesiqandisi ngenxa yethempelesha ephansi nokuncibilika okuphansi; ngakolunye uhlangothi, ukushisa okuphansi kanye ne-viscosity ephezulu, uwoyela ohlukanisayo kulula ukunamathela odongeni lwangaphakathi lepayipi, futhi kunzima ukugeleza. Ukwehla kwamazinga okushisa okuhwamuka, kulukhuni kakhulu ukubuyisa uwoyela. Lokhu kudinga ukuthi ukwakhiwa nokwakhiwa kwepayipi lokuhwamuka kanye nepayipi elibuyayo kufanelekile ekubuyiseleni uwoyela. Umkhuba ojwayelekile ukwamukela ukwakheka kwamapayipi okwehlayo nokuqinisekisa isivinini esikhulu sokugeleza komoya.

Ezinhlelweni zefriji ezinamazinga okushisa aphansi ikakhulukazi, ngaphezu kokusebenzisa izihlukanisi zikawoyela ezisebenza kahle kakhulu, kuvame ukungezwa izinyibilikisi ezikhethekile ukuvimbela uwoyela wokuthambisa ekuvimbeleni ama-capillaries nama-valve wokunweba, nokusiza ekubuyiseni uwoyela. Ngasikhathi sinye, abanye abantu basebenzisa uwoyela owakhelwe ngaphakathi we-air conditioner ukufaka uwoyela wangaphandle. Phezulu, kusindisa izindleko, kepha ngokwezindleko zokusebenzisa zesikhathi eside zohlelo, kuzokhulisa kuphela izindleko zokusebenza. Ukusebenza kohlelo kuzoba kubi kakhulu.

Ekusebenziseni okusebenzayo, izinkinga zokubuyisa uwoyela ezibangelwe ukwakhiwa okungafanele kwe-evaporator nolayini wokubuyela akujwayelekile. Kuzinhlelo ze-R22 ne-R404A, ukubuya kukawoyela kwe-evaporator enezikhukhula kunzima kakhulu, futhi ukwakheka kwepayipi lokubuyisa uwoyela kohlelo kufanele kuqaphele kakhulu. Kuhlelo olunjalo, ukusetshenziswa kukawoyela osebenza kahle kunganciphisa kakhulu inani lamafutha angena kwipayipi lesistimu, futhi kwandise ngempumelelo isikhathi esingabuyisi sepayipi lokubuyisa umoya ngemuva kokuqala.

Lapho i-compressor iphakeme kune-evaporator, ukugoba okubuyisela uwoyela kupayipi lokubuyela mpo kuyadingeka. Ijika lokubuyela kufanele lihlangane ngangokunokwenzeka ukunciphisa ukugcinwa kukawoyela. Isikhala phakathi kokugoba okubuyisa uwoyela kufanele kufaneleke. Lapho inani lokugoba okubuyisa uwoyela likhulu ngokwengeziwe, kufanele kufakwe uwoyela othambisa. Ulayini wokubuyisa uwoyela wesistimu yokulayisha eguquguqukayo kufanele futhi uqaphele. Lapho umthwalo wehlisiwe, isivinini sokubuyisa umoya sizokwehla, isivinini esiphansi kakhulu asikulungele ukubuya kukawoyela. Ukuze kuqinisekiswe ukubuya kukawoyela ngaphansi komthwalo ophansi, ipayipi lokumunca elime mpo lingamukela amapayipi amile kabili.

Ngaphezu kwalokho, ukuqala kwe-compressor kaningi akulungele ukubuya kukawoyela. Njengoba i-compressor iyema isikhathi esifushane sokusebenza okuqhubekayo, asikho isikhathi sokwenza ukugeleza komoya okuqinile okushesha kupayipi lokubuya, kanti uwoyela othambisa umzimba ungahlala kuphela epayipini. Uma ukubuya kukawoyela kungaphansi kukawoyela kaBen, icompressor izoshoda ngamafutha. Uma isikhathi sisifushane, ipayipi liba lide futhi uhlelo luyinkimbinkimbi ngokwengeziwe, inkinga yokubuya kukawoyela ivelele kakhulu. Ngakho-ke, ngokuvamile, ungaqali i-compressor njalo.

Ngamafuphi, ukuntuleka kukawoyela kuzodala ukungathambisi okukhulu. Imbangela yokushoda kukawoyela akuyona inani nesivinini se-screw-type chiller, kepha ukubuya kukawoyela okungalungile kohlelo. Ukufakwa kwesihlukanisi sikawoyela esisebenza kahle kakhulu kungabuya ngokushesha uwoyela futhi kunwebe isikhathi sokusebenza se-compressor ngaphandle kokubuya kukawoyela. Idizayini ye-evaporator kanye nepayipi legesi elibuyayo kumele licabangele ukubuya kukawoyela. Izindlela zokulungisa njengokugwema ukuqala njalo, ukuncishiswa kwesikhathi, ukugcwaliswa okufike ngesikhathi kwefriji, kanye nokufaka esikhundleni esifanele izingxenye zokugqoka (njengamabombo) nakho kuyasiza ekubuyiseni uwoyela
