Mayelana neyunithi yokupholisa

Iyunithi yokushisa (eyaziwa nangokuthi ifriji, iyunithi yokushisa, iyunithi yamanzi eqhwa, noma imishini yokupholisa) uhlobo lwemishini yokushisa. Embonini yokushisa, ama-chiller ahlukaniswe ngezinhlobo ezipholile emoyeni kanye nezipholile emanzini. Ngokusekelwe ku-compressor, ahlukaniswe kabanzi ngama-screw, scroll, kanye nama-centrifugal chiller. Ngokuphathelene nokulawula izinga lokushisa, ahlukaniswe ngama-chiller ezimboni anezinga lokushisa eliphansi kanye nama-chiller anokushisa okujwayelekile. Ama-chiller anokushisa okujwayelekile ngokuvamile alawulwa ngaphakathi kwebanga eliphakathi kuka-0°C kuya ku-35°C, kuyilapho ama-chiller anokushisa okuphansi ngokuvamile alawulwa ngaphakathi kwebanga eliphakathi kuka-0°C kuya ku-100°C.

Ama-chiller ngokuvamile ahlukaniswa ngendlela yokupholisa ngokuthi apholile ngamanzi noma apholile emoyeni. Ngobuchwepheshe, ukupholisa ngamanzi kunikeza ukusebenza kahle kwamandla okuphezulu okungu-300 kuya ku-500 kcal/h kunokupholisa umoya.

Ama-Chiller Apholiswe Umoya
Izici
1. Akukho mbhoshongo wokupholisa odingekayo, ukufakwa okulula nokufuduka, kufanelekile ukusetshenziswa lapho amanzi engekho khona.
2. Injini yefeni enomsindo ophansi, ukusebenza okuhle kakhulu kokupholisa kanye nokusebenza kokupholisa, indlela yokulawula ugesi ezinzile, kanye nokuvimbela ukugqwala okuhle kakhulu.

Ama-Chiller Apholiswe Ngamanzi
Izici
1. Iphaneli eklanywe ngendlela ye-ergonomic, ukulawula okuzenzakalelayo ngokugcwele, kanye nesilawuli sokushisa sikagesi esinembile siqinisekisa ukusebenza okuzinzile kwesikhathi eside.
2. Ama-heat exchanger asebenza kahle kakhulu anciphisa ukulahleka kokupholisa, asize ukubuya kwamafutha, futhi avimbele amashubhu okudlulisa ukushisa ekuqandeni nasekuqhekekeni.

I-chiller epholiswe ngamanzi isebenzisa i-evaporator yegobolondo ne-tube ukushintshanisa ukushisa phakathi kwamanzi ne-refrigerant. Ngemva kokuba uhlelo lwe-refrigerant lumunce umthwalo wokushisa emanzini futhi lupholise amanzi ukuze lukhiqize amanzi abandayo, i-compressor iletha ukushisa ku-shell ne-tube condenser. I-refrigerant namanzi ashintshana ukushisa ukuze amanzi amunce ukushisa bese ekhipha ukushisa embhoshongweni wokupholisa wangaphandle ngamapayipi amanzi ukuze kuchitheke (ukupholisa amanzi). Ekuqaleni, i-compressor imunca igesi ye-refrigerant ephansi, enomfutho ophansi ngemva kokuhwamuka nokupholisa, bese iyicindezela ibe yigesi ye-high temperature, enomfutho ophakeme bese iyithumela ku-condenser; igesi ye-high pressure, enomfutho ophakeme ipholiswa yi-condenser bese ifinyela ibe uketshezi lwe-high temperature, olunomfutho ophakeme; lapho uketshezi lwe-high temperature, olunomfutho ophakeme lugeleza ku-thermal expansion valve, lufakwa ku-throttle lube umusi omanzi we-low temperature, nomfutho ophansi bese lugeleza ku-evaporator yegobolondo ne-tube, lumunce ukushisa kwamanzi abandayo ku-evaporator ukuze kwehliswe izinga lokushisa lamanzi; i-refrigerant ephefumulayo imuncwa iphinde ibuyele ku-compressor, bese umjikelezo olandelayo wokuqandisa uyaphindwa.

Isikulufa Esipholile Esinomoya
Izici
1. I-condenser epholiswe ngomoya iyi-platinum ye-aluminium ephilizayo enohlobo lwe-fin, enowoyela ophindwe kabili. Yakhiwe kusetshenziswa imishini yokucubungula i-heat exchanger yobungcweti, inesakhiwo esincane, usayizi omncane, isisindo esincane, kanye nokusebenza kahle kokushintshanisa ukushisa. Ifakwe ifeni yokugeleza kwe-axial enesivinini esiphansi, enamabala amakhulu, enciphisa ngempumelelo umsindo wokusebenza kanye nomthelela emvelweni.
2. Uhlelo lokulawula iyunithi lusebenzisa isilawuli esifakiwe se-PLC esingahle sihlelwe esinesibonisi esikhulu sesikrini sokuthinta ukuze kube nesibonisi esilula nesiqondakala kalula.
3. Le yunithi ifakwe amadivayisi okuvikela ukuphepha athembekile, okuhlanganisa izivikeli ze-voltage ephezulu nephansi, izivikeli ze-exhaust overheat, izivikeli ze-compressor motor overheat, izivikeli ze-overload current, izivikeli ze-antifreeze temperature, izivikeli ze-water flow, amaswishi okuma okuphuthumayo, ama-fusible plugs azwela ukushisa, kanye nama-valve okuphepha.

Izici
1. Isakhiwo esilula, ukushintshaniswa kokushisa okuzinzile, ukusebenza kahle okuhlala isikhathi eside, kanye nokugcinwa okulula.
2. Uhlelo lokulawula lweyunithi lusebenzisa isilawuli esifakiwe esingahle sihlelwe yi-PLC, kanti isikhombikubona somshini womuntu sinesikrini esikhulu sokuthinta, esinikeza isikhombikubona esilula nesiqondakala kalula kanye nokusebenza okulula.
