Umshini wokuvimba iqhwa ubhekisela emshinini oklanyelwe ukukhiqiza amabhlogo amakhulu eqhwa.Imishini enjalo ivame ukusetshenziselwa izinjongo zezohwebo nezimboni, njengasembonini yokudoba, elungisa ukudla neziphuzo.Umshini we-block block ungakhiqiza amabhulokhi amakhulu eqhwa ukuze unikeze izinto zokuhamba ezibandayo, ukugcinwa kanye nezidingo zokupholisa.Le mishini ngokuvamile isebenzisa i-condenser ne-compressor ukuze ihlanganise futhi imise amanzi, yakhe iqhwa eliqinile.
Umshini weqhwa we-Shanghai Jingyao unohlelo lokusebenza oluhlakaniphile, olulula futhi olusebenziseka kalula.Ngokusebenzisa izinkinobho zokulawula kuphaneli yokusebenza, abasebenzisi bangakwazi ukusetha kalula imingcele efana nesikhathi sokwenza iqhwa, imodi yokwenza iqhwa, nosayizi we-ice cube.Imishini iphinde ifakwe uhlelo lokuvikela ukuphepha olungaqapha isimo sokusebenza sezinto zokusebenza futhi imise ngokuzenzakalelayo ukusebenza ukuze kuqinisekiswe ukusetshenziswa okuphephile.
