Refrigeration compressors are the heart of the refrigeration system, and most compressors today use hermetic reciprocating compressors. Ukuphakamisa ukuqaqamba kusuka ekucindezelweni okuphezulu kuya kokuphezulu nokujikeleza esiqandisini ngokuqhubekayo, uhlelo luqhubeka nokukhipha ukushisa kwangaphakathi endaweni engenhla kwesistimu.
Umsebenzi we-condenser ukupholisa umfutho ophakeme, umvikeli wefriji odumile okhishwe yi-compressionant compressor esiqandisini esinguketshezi, futhi ukushisa kwawo kuthathwa ngamanzi apholile. This allows the refrigeration process to continue continuously.
I-Evaporator iyingxenye eyinhloko yokushintshanisa kokushisa kwesomisi sokuqapha, futhi umoya ocindezelwe uphonswe ngenkani emvela I-liquid ye-Low-Pressure Sufricter iba yi-Sufricture-Pressure Sufrigont Vapor ngesikhathi sokushintshwa kwesigaba ku-Evaporator, edonsa ukushisa okuzungezile ngesikhathi sokushintsha kwesigaba, ngaleyo ndlela kupholise umoya ocindezelwe.
Iningi lemishini yefindisi evuselelwayo linokushisa okushisa, okuyinto eshintshi lokushisa elishintshana ukushisa phakathi komoya nomoya, ngokuvamile i-tubular exchanger (eyaziwa nangokuthi i-Shell and Tube Exchanger). Umsebenzi oyinhloko we-Exchanger Exchanger efrijini "ukuze" ubuyise "amandla apholile athathwe yi-aircor ephakeme ngemuva kokupholisa i-air compressor, bese esebenzisa lo mphumela opholile opholile we-comprescessor, bese ehlukaniswa ngumoya namanzi generally above 40 °C), thereby reducing the heating load of the refrigeration and drying system and achieving the purpose of saving energy. Ngakolunye uhlangothi, izinga lokushisa lokushisa umoya ophonswe ngokushisa elisezingeni eliphakeme elisezingeni eliphakeme liyatholakala, ukuze udonga lwangaphandle lwepayipi lokuhambisa umoya olucindezelwe lungabangeli "ukugcwala" into yokushisa ngaphansi kwamazinga okushisa akhona. Ngaphezu kwalokho, ngemuva kokushisa komoya okucindezelwe kukhuphuka, umswakama ohlobene nomoya ocindezelwe ngemuva kokomiswa kwehlisiwe (ngokuvamile kungaphansi kwama-20%), okuzuzisa ukuvimbela ukugqwala kwensimbi. Abanye abasebenzisi (isib. Ngezitshalo zokwehlukanisa zomoya) badinga umoya ocindezelwe ngokuqukethwe komswakama ophansi namazinga okushisa aphansi, ngakho-ke i-hendiger dyer ayisasebenzi nge-exchanger yokushisa. Since the heat exchanger is not installed, the cold air cannot be recycled, and the heat load of the evaporator will increase a lot. Kulokhu, hhayi kuphela amandla e-compressiona compressor adinga ukwenyuswa ukuze anxephezele amandla, kodwa futhi nezinye izinto zohlelo lonke lesiqandisi (i-evaporator, ama-condenser kanye nezinto eziphoqayo) kudingeka ukukhuphuka ngokufanele. Ngokombono wokuvuselelwa kwamandla, sihlala sithemba ukuthi ukukhuphuka kwamazinga okushisa okuphuma kwesiqandisi, okungcono (okushisa okuphezulu, okubonisa ukulungiswa kwamandla okwengeziwe), futhi kungcono ukuthi akukho mehluko wokushisa phakathi kwe-inlet nokuphuma. Kepha eqinisweni, akunakwenzeka ukufeza lokhu, lapho amazinga okushisa amoyeni engaphansi kuka-45 ° C, akujwayelekile ukuthi amazinga okushisa angenayo kanye nokuphuma kokuphuma kokomisa okuyisiqandisi ukuhluka ngaphezulu kuka-15 ° C.
Umoya ocindezelwe → Ukuhlunga okwenziwe ngomshini → Ukushintshaniswa kokushisa (ukukhishwa kokushisa),
To reduce the compressed air temperature, the evaporation temperature of the refrigerant must also be very low. Lapho i-Heafiger Dryer ipholisa umoya ocindezelwe, kukhona ungqimba lwe-condensate enjengefilimu ebusweni be-finer ye-evaporator, uma izinga lokushisa le-fin lingaphansi kwe-zero, ingaphezulu kwe-condensate ingahle iqhwa, ngalesi sikhathi:
A. Due to the attachment of a layer of ice with a much smaller thermal conductivity on the surface of the inner bladder fin of the evaporator, the heat exchange efficiency is greatly reduced, the compressed air can not be fully cooled, and because of the insufficient heat absorption, the refrigerant evaporation temperature may be further reduced, and the result of such a cycle will inevitably bring many adverse consequences to the refrigeration system (such as “liquid compression”);
B. Ngenxa yesikhala esincane phakathi kwamaphiko ku-evaporator, lapho ama-fins eqhwa, indawo yokujikeleza komoya ecindezelwe izoncishiswa, futhi ngisho nendlela yomoya izovinjwa ezimweni ezinzima, okungukuthi, "i-Ice Blockage"; Ngamafuphi, amazinga okushisa okushisa ama-Dew Dew Feet wefriji kufanele abe ngaphezulu kuka-0 ° C, ukuze kuvikeleke izinga lokushisa le-Dew Point kusuka ekuvikelweni kakhulu, kutholakala nge-valve valve noma i-fluorine solenoid valve). Lapho amazinga okushisa ama-dew point ephansi kune-0 ° C, i-bypass valve (noma i-fluorine solenoid valve) ngokuzenzakalelayo avulekele (noma i-highs-liquist tank ephakeme kakhulu, futhi i-sum-liqur-liquid Tank frequent rate in the compressor inlet), ukuze izinga lokushisa le-depressional liphakanyiswe ngenhla 0 ° C.
C. Ngokombono wohlelo lokusetshenziswa kwamandla kohlelo, izinga lokushisa lokuhwamuka liphansi kakhulu, okuholela ekwehleni okukhulu kwi-compressorfream coefflicred kanye nokwanda kokusetshenziswa kwamandla.
2.2 Bheka ideshibhodi, imitha eqandisi ephezulu yokucindezela kufanele ikhuphuke kancane kancane ku-1,4MPA, kanye ne-esiqandisayo yemitha yengcindezi ephansi kufanele yehle kancane kuye cishe ngo-0.4MPA; at this time, the machine has entered the normal working state.
2.4 Bheka ukuthi ngabe i-Inlet kanye ne-Outlett Pressure Peressure Geages evamile (umehluko phakathi kokufundwa kwamamitha amabili ka-0.03MPA kufanele kube okujwayelekile).
4.4 Kukhona ama-valves we-bypass kunethiwekhi yepayipi ebeka i-inlet kanye nokuphuma kwe-dryer, futhi i-bypass valve kumele ivalwe ngokuqinile ngesikhathi sokusebenza ukuze uvikele umoya wepayipi we-air towstream.
4.11 I-Air-apholile i-Devikelis Drople Fan epholile ilawulwa yingcindezi yokucindezela, futhi kuyinto evamile ukuthi fan ukungaphenduki lapho i-hendigere dryer isebenza ngokushisa okuphansi okukhona. As the refrigerant high pressure increases, the fan starts automatically.
