Mayelana neyunithi yokupholisa

Iyunithi yokupholisa (eyaziwa nangokuthi isiqandisi, iyunithi yesiqandisi, iyunithi yamanzi eqhwa, noma okokupholisa) wuhlobo lwempahla yesiqandisi. Embonini yeziqandisi, ama-chiller ahlukaniswa ngezinhlobo ezipholile emoyeni nezipholile ngamanzi. Ngokusekelwe ku-compressor, aphinde ahlukaniswe abe isikulufu, ukuskrola, nama-centrifugal chiller. Ngokuphathelene nokulawulwa kwezinga lokushisa, ahlukaniswa ngokwezinga lokushisa eliphansi lezimboni kanye nezibandisi ezinezinga lokushisa elivamile. Izibandisi ezibandisa izinga lokushisa elijwayelekile ngokuvamile zilawulwa phakathi kwebanga elingu-0°C kuya ku-35°C, kuyilapho okubandayo okunezinga lokushisa eliphansi ngokuvamile kulawulwa phakathi kwebanga elingu-0°C kuya ku-100°C.

Ama-chiller ngokuvamile ahlukaniswa ngendlela yokupholisa njengamanzi apholile noma apholile emoyeni. Ngobuchwepheshe, ukupholisa amanzi kunikeza amandla aphezulu angama-300 kuya ku-500 kcal/h kunokupholisa komoya.

Ama-Chillers Apholile emoyeni
Izici
1. Awukho umbhoshongo wokupholisa odingekayo, ukufakwa kalula kanye nokuthuthwa kwenye indawo, olungele izinhlelo lapho amanzi eyindlala khona.
2. Injini yefeni enomsindo ophansi, ukusebenza okuhle kakhulu kokupholisa nokusebenza okujiyayo, umshini wokudonsa umoya ozinzile, nokuvikela ukugqwala okuhle kakhulu.

Ama-Chiller Apholile Amanzi
Izici
1. Iphaneli eklanywe nge-ergonomically, isilawuli esizenzakalelayo ngokugcwele, nesilawuli sokushisa sikagesi esinembayo siqinisekisa ukusebenza okuzinzile kwesikhathi eside.
2. Izishintshisi zokushisa ezisebenza kahle kakhulu zinciphisa ukulahleka kokupholisa, zenza kube lula ukubuya kukawoyela, futhi zivimbele amashubhu okudlulisa ukushisa ukuthi angaqandi futhi aqhekeke.

I-chiller epholiswe ngamanzi isebenzisa igobolondo nesishuphuki seshubhu ukushintshanisa ukushisa phakathi kwamanzi nesiqandisi. Ngemva kokuba uhlelo lwesiqandisi lumunca umthwalo wokushisa emanzini futhi lupholise amanzi ukuze lukhiqize amanzi abandayo, i-compressor iletha ukushisa kugobolondo kanye ne-tube condenser. Isiqandisi kanye nokushisa kokushintshana kwamanzi ukuze amanzi amunce ukushisa abese ekhipha ukushisa embhoshongweni wokupholisa wangaphandle ngamapayipi amanzi ukuze akuchithe (ukupholisa amanzi). Ekuqaleni, i-compressor idonsa izinga lokushisa eliphansi, igesi epholile ephansi yokucindezela ngemva kokuhwamuka nokupholisa, bese icindezela ibe yi-high-temperature, igesi ephezulu yokucindezela futhi iyithumele ku-condenser; i-high-pressure, i-high-temperature gas ipholiswa yi-condenser futhi ihlanganiswe ibe uketshezi olujwayelekile lokushisa, olunomfutho ophezulu; lapho izinga lokushisa elivamile, uketshezi olunomfutho ophezulu lugeleza ku-valve yokwandisa ukushisa, luphonswa ku-steam olumanzi olunokushisa okuphansi, ukucindezela okuphansi futhi lugeleze kugobolondo kanye ne-tube evaporator, lubambe ukushisa kwamanzi abandayo ku-evaporator ukuze kwehlise izinga lokushisa lamanzi; isiqandisi esihwamukile sibe sesimuncwa emuva ku-compressor, bese umjikelezo wesiqandisi olandelayo uyaphindwa.

I-Air-Cooled Screw Chiller
Izici
1. I-condenser epholile emoyeni iyi-fin-type, i-double-oil corrugated hydrophilic aluminium platinum. Ikhiqizwe kusetshenziswa imishini yokucubungula isishintshi sokushisa esezingeni eliphezulu, inesakhiwo esihlangene, usayizi omncane, isisindo esilula, kanye nokusebenza kahle kokushintshana kokushisa okuphezulu. Ifakwe i-axial flow fan enesivinini esiphansi, ene-blade enkulu, enciphisa ngempumelelo umsindo wokusebenza nomthelela wemvelo.
2. Uhlelo lokulawula iyunithi lusebenzisa isilawuli esihlelekayo se-PLC esingenisiwe esinesibonisi esikhulu sesikrini sokuthinta ukuze kube nesixhumi esibonakalayo esilula nesinembile.
3. Iyunithi ifakwe izinto ezinokwethenjelwa zokuvikela ukuphepha, okuhlanganisa izivikeli zamandla kagesi aphezulu naphansi, izivikeli ze-exhaust overheat, izivikeli ze-compressor motor overheat, izivikeli zamanje ezigcwala kakhulu, izivikeli ezivimbela ukushisa, izivikeli zokugeleza kwamanzi, izitophu zokumisa izimo eziphuthumayo, amapulagi e-fusible azwela ukushisa, namavalvu okuphepha. I-Screw Chiller Epholile Ngamanzi

Izici
1. Isakhiwo esilula, ukushintshanisa ukushisa okuzinzile, ukusebenza kahle okuhlala isikhathi eside, nokugcinwa kalula.
2. Isistimu yokulawula yeyunithi isebenzisa isilawuli esihlelekayo se-PLC esingenisiwe, futhi isixhumi esibonakalayo somshini womuntu sibonisa isikrini sokuthinta esikhulu, esinikeza isixhumi esibonakalayo esilula nesinembile nokusebenza okulula.
