I-valve yokwandisa iyingxenye ebalulekile yesistimu yokuqandisa, evame ukufakwa phakathi kwesilinda sokugcina uketshezi kanye ne-evaporator. I-valve yokwandisa yenza i-refrigerant yoketshezi ekushiseni okuphakathi kanye nomfutho ophezulu ibe umusi omanzi ekushiseni okuphansi kanye nomfutho ophansi ngokugoqa kwayo, bese i-refrigerant imunca ukushisa ku-evaporator ukuze kufezwe umphumela wokuqandisa. I-valve yokwandisa ilawula ukugeleza kwe-valve ngokushintsha kokushisa okukhulu ekugcineni kwe-evaporator ukuvimbela ukusetshenziswa okunganele kwendawo ye-evaporator kanye nesimo sokugoqa isilinda.
Kalula nje, i-valve yokwandisa yakhiwe ngomzimba, iphakheji yokuzwa izinga lokushisa kanye nepayipi lokulinganisela
Isimo esifanelekile sokusebenza sevalvu yokunweba kufanele kube ukushintsha ukuvulwa ngesikhathi sangempela nokulawula izinga lokugeleza ngokushintsha komthwalo we-evaporator. Kodwa eqinisweni, ngenxa yokuguquguquka kokudluliselwa kokushisa emvilophini yokuzwa izinga lokushisa, impendulo yevalvu yokunweba ihlala ihamba kancane kancane. Uma sidweba umdwebo wokugeleza kwesikhathi wevalvu yokunweba, sizothola ukuthi akuyona ijika elibushelelezi, kodwa umugqa ogobile. Ikhwalithi yevalvu yokunweba ibonakala ku-amplitude yegagasi. Uma i-amplitude inkulu, ukusabela kwevalvu kuhamba kancane futhi ikhwalithi iba mbi kakhulu.
