Yiziphi izizathu eziyinhloko zokushisa ngokweqile kwe-compressor?

Izizathu eziyinhloko zokushiswa kwamazinga okushisa kwegesi yokukhipha zimi kanje: izinga lokushisa lomoya eliphakeme lokubuya, umthamo omkhulu wokushisa wemoto, isilinganiso sokucindezelwa okuphezulu, ingcindezi ephezulu yokuqina, nokukhethwa kwesiqandisi okungafanele.

Ukushisa okuphezulu komoya

Ithempelesha yokubuyisa umoya ihlobene nezinga lokuhwamuka. Ukuze uvimbele ukubuya kuketshezi, ipayipi lomoya elibuyayo ngokuvamile lidinga ukubuyiswa komoya okuphezulu okungama-20 ° C. Uma ipayipi lomoya elibuyayo lingavikelekile kahle, i-superheat izodlula kude ama-20 ° C.

Ukuphakama kokushisa komoya okubuyayo, kuphakama ukushisa kwesilinda nokudonsa kokushisa. Njalo lapho izinga lokushisa lomoya libuya ngo-1 ° C, izinga lokushisa qeda lizokwenyuka ngo-1 liye ku-1.3 ° C.

Ukushisa imoto

Okwe-compressor yokupholisa umoya obuyayo, umhwamuko wesiqandisi ufutheliswa yimoto njengoba igeleza ngomgogodla wezimoto, futhi ithempelesha lokuncela isilinda liphinde lenyuka. Inani le-calorific yemoto lithinteka ngamandla nokusebenza kahle, futhi ukusetshenziswa kwamandla kuhlobene kakhulu nokuhamba, ukusebenza kahle kwevolumu, izimo zokusebenza, ukumelana nokungqubuzana, njll.

Kuhlobo lokupholisa lomoya olubuyayo lwe-semi-hermetic compressor, ukukhuphuka kwezinga lokushisa kwefriji emgodini wezimoto cishe kuphakathi kuka-15 no-45 ° C. Ku-compressor epholile yomoya (umoya opholile), uhlelo lwefriji aludluli kuma-windings, ngakho-ke ayikho inkinga yokushisa kwezimoto.

Isilinganiso sokuminyaniswa siphezulu kakhulu

Ukushisa kwe-exhaust kuthinteka kakhulu isilinganiso sokucindezela. Ukukhula kwesilinganiso sokucindezela, kukhuphuka izinga lokushisa lokukhipha. Ukunciphisa isilinganiso sokucindezelwa kunganciphisa kakhulu ukushisa kokukhipha. Izindlela ezithile zibandakanya ukukhuphula ingcindezi yokudonsa nokunciphisa ingcindezi yokukhipha.

Ingcindezi yokudonsa inqunywa ingcindezi yokuhwamuka kanye nokumelana kwepayipi lokudonsa. Ukwandisa ukushisa kokuhwamuka kungakhuphula ngempumelelo ingcindezi yokudonsa futhi kunciphise ngokushesha isilinganiso sokuminyaniswa, ngaleyo ndlela kunciphise ukushisa kokukhipha.

Abanye abasebenzisi bakhetha ukukholelwa ukuthi ukwehla kwamazinga okushisa okuhwamuka, isivinini sokupholisa siyashesha. Lo mbono empeleni unezinkinga eziningi. Yize ukwehlisa ukushisa kokuhwamuka kungakhuphula umehluko wamakhaza wokushisa, amandla efriji wecompressor ancishisiwe, ngakho-ke isivinini sokuqandisa akusona esisheshayo. Ngaphezu kwalokho, ukwehla kwamazinga okushisa okuhwamuka, kwehla isibalo semoto esiqandisini, kepha umthwalo uyanda, isikhathi sokusebenza siyandiswa, futhi ukusetshenziswa kwamandla kuzokwanda.

Ukunciphisa ukumelana nentambo yomoya ebuyayo nakho kungakhuphula umfutho womoya obuyayo. Izindlela ezithile zifaka ukufakwa esikhundleni kwesihlungi somoya esingcolile ngesikhathi esifanele, nokunciphisa ubude bepayipi lokuhwamuka nolayini womoya obuyayo. Ngaphezu kwalokho, isiqandisi esanele futhi siyisici sokucindezela okuphansi kokudonsa. Isiqandisi kufanele sigcwaliswe ngesikhathi ngemuva kokulahleka kwaso. Ukuzijwayeza kukhombisa ukuthi ukunciphisa ukushisa kokukhipha ngokunyusa ingcindezi yokudonsa kulula futhi kusebenza kangcono kunezinye izindlela.

Isizathu esiyinhloko sengcindezi yokukhipha ephezulu ngokweqile ukuthi ingcindezi yokuncipha iphakeme kakhulu. Indawo enganele yokushabalalisa ukushisa kwesikhuthazi, ukungcolisa amanzi, ivolumu yomoya yokupholisa enganele noma ivolumu yamanzi, amanzi apholile kakhulu noma ukushisa komoya, njll. Kungadala ingcindezi yokwehlisa ngokweqile. Kubaluleke kakhulu ukukhetha indawo efanelekayo yokugudluza nokugcina ukugeleza okwanele okuphakathi kokupholisa.

Umklamo we-compressor oshisa kakhulu futhi one-air conditioning unesilinganiso esiphansi sokusebenza kokuminyaniswa. Ngemuva kokusetshenziselwa ifriji, isilinganiso sokucindezelwa siphindwe kabili, izinga lokushisa qeda liphezulu kakhulu, futhi ukupholisa akukwazi ukuqhubeka, okuholela ekushiseni ngokweqile. Ngakho-ke, kuyadingeka ukugwema ukusetshenziswa kwe-compressor ngokweqile futhi wenze i-compressor isebenze ngenani eliphansi kakhulu lokucindezela. Kwezinye izinhlelo zokushisa okuphansi, ukushisa ngokweqile kuyimbangela eyinhloko yokwehluleka kwe-compressor.

Anti-ukunwetshwa nokuxutshwa kwegesi

Ngemuva kokuqala kwesifo sokudonsa, igesi enomfutho ophakeme ebhajwe emgodini wesilinda izobhekana nenqubo yokulwa nokwanda. Ngemuva kokunwetshwa okuguqukayo, ingcindezi yegesi ibuyela ekucindezelweni kokudonsa, futhi amandla asetshenziselwe ukucindezela le ngxenye yegesi alahlekile ekukhulisweni okuphambene nalokho. Lapho kuncipha imvume, kuncane ukusetshenziswa kwamandla okubangelwe ukwandiswa kokukhulisa ngakolunye uhlangothi, futhi kukhulu nokungeniswa komoya ngakolunye uhlangothi, okwandisa kakhulu isilinganiso sokusebenza kahle kwamandla kwe-compressor.

Ngesikhathi senqubo yokulwa nokwanda, igesi ixhumana nendawo ephezulu yokushisa kwepuleti ye-valve, phezulu kwepiston kanye naphezulu kwesilinda ukumunca ukushisa, ngakho-ke izinga lokushisa kwegesi ngeke lehle ekushiseni kokumunca ekugcineni anti-ukunwetshwa.

Ngemuva kokuthi ukwandiswa kokunwebeka sekuphelile, inqubo yokuhogela iqala. Ngemuva kokuthi igesi ingene kwisilinda, ngakolunye uhlangothi, ixubeka negesi elwa nokwanda futhi izinga lokushisa lenyuka; ngakolunye uhlangothi, igesi elixubekile limunca ukushisa okuvela odongeni ukuze kwandise izinga lokushisa. Ngakho-ke, izinga lokushisa kwegesi ekuqaleni kwenqubo yokuminyanisa liphakeme kunezinga lokudonsa. Kodwa-ke, njengoba inqubo yokwandiswa okuphindayo nenqubo yokudonsa imfishane kakhulu, izinga lokushisa langempela likhawulelwe kakhulu, ngokuvamile lingaphansi kuka-5 ° C.

Ukwelulwa kubangelwa ukuvalwa kwe-cylinder, okuwukushoda okungenakugwenywa kwama-piston compressors wendabuko. Uma igesi esemgodini we-valve wepuleti ye-valve ingakwazi ukukhishwa, kuzoba nokulwa nokwandiswa.

Ukuphakama kokushisa kokucinana nezinhlobo zefriji

Amafriji ahlukene anezakhiwo ezahlukahlukene ezishisayo nezingokomzimba, futhi izinga lokushisa qeda likhuphuka ngokuhlukile ngemuva kwenqubo efanayo yokucindezela. Ngakho-ke, kufanele kukhethwe amafriji ahlukene emazingeni okushisa ahlukahlukene.

isiphetho nesiphakamiso:

I-compressor akufanele ibe nezimo ezishisa ngokweqile njengokushisa okuphezulu kwemoto kanye nokushisa okuphezulu ngokweqile kokushisa kwe-steam ekusebenzeni okujwayelekile kwe-compressor. Ukushisa ngokweqile kwe-compressor kuyisignali yephutha ebalulekile, ekhombisa ukuthi kunenkinga enkulu ohlelweni lwefriji, noma i-compressor isetshenziswa futhi igcinwe ngokungafanele.

Uma umthombo we-compressor okweqile ushisa ohlelweni lwefriji, inkinga ingaxazululwa kuphela ngokwenza ngcono ukwakhiwa nokugcinwa kohlelo lwefriji. Ukushintshela ku-compressor entsha akukwazi ukuqeda inkinga yokushisa ngokweqile ngokuyisisekelo.
