Kungani ama-chiller asezimbonini engasebenzisi ama-valve we-manual mpintsha? Yini enhle kangaka nge-valve yokunweba eshisayo?

Manual mpintsha valve, kule i zamanjeAma-chiller ase-ndustrial, akukho sicelo se-valve mpintsha. I-valve mpintsha ye-manual empeleni idinga ukusebenza ngesandla. Ingasetshenziswa kuphela kuma-evaporator amanzi futhi omile. Ibhizinisi kufanele lifake opharetha abazinikele ukulungisa ukugeleza okwenziwa ngesandla ngokuya ngomphumela wokuhwamuka. Le yindlela yokusebenza kwe-valve ebizwa ngokuthi yi-manual mpintsha. Ngakho-ke, ayizilungele izinhlelo zanamuhla ze-chiller ezidinga ukusakazwa okuzenzakalelayo. Ama-valve wokunweba asetshenziswa kakhulu kuma-chiller ezimboni zanamuhla.

Isetshenziswa kakhulu ezinhlelweni ze-fluorine ezifana no-R12, R22 no-R134a. Kuyinto efanelekile kakhulu yokushwabanisa ohlelweni lwefriji lapho iFreon isetshenziswa khona njengesiqandisi. Kusho ukuthini i-valve yokunweba okushisayo? Njengoba igama lisho, i-valve yokunweba eshisayo ilawula ukuvulwa nokuvalwa kwe-valve yokunweba ngokushisa. Ingxenye yokuzwa izinga lokushisa lokunwetshwa okushisayo ifakiwe ngemuva kwe-evaporator, ukuze izinga lokushisa kwegesi eliyi-refrigerant eliphuma ku-evaporator lidlule, bese unquma ukuthi hlobo luni lokuvula nokuvala ingxenye yedivayisi ephihlizayo okufanele ibe nayo.

Eqinisweni, i-valve yokunwebeka eshisayo iyinhlobo esetshenziswa kakhulu ye-valve yokunweba, futhi futhi iluhlobo lwe-valve yokwandisa enokuzinza okuhle. Izindleko zokusetshenziswa kwayo nazo ziphansi kakhulu. Kodwa-ke, ama-valve wokunweba ezishisayo nawo ahlukaniswe ngezinhlobo ezahlukahlukene, kufaka phakathi uhlobo lwebhalansi yangaphakathi. Futhi ezinye izinhlobo, ububanzi besicelo buhlukile. Kwama-chiller amancane namancane, ukusebenzisa i-valve yokunwebeka yokushisa okulinganiselwe ngaphakathi kungahlangabezana nezidingo zokuhwamuka kwe-evaporator kanye ne-chiller yonke, futhi kungonga nokukhiqiza. Ngaphezu kwezindleko zokukhiqiza, intengo kanye nezindleko ze-valve yokukhulisa ezishisayo ezilinganiselwe ngaphakathi ziphansi kakhulu.
