Kutheni le nto chiller zeshishini zingasebenzisi iivevophu zokuhambisa ngokuthe ngqo? Yintoni elungileyo malunga nevalve yokwandisa ubushushu?

I-valve yokunyusa ngesandla, kwi-i yangokuI-chiller chillers, Akukho sicelo sevalveji sombane. Ivalve yentshukumo yokubamba ngokoqobo ifuna ukusebenza ngesandla. Ingasetyenziselwa kuphela kwi-evaporator ezimanzi nezomileyo. Ishishini kufuneka lifakele umsebenzisi azinikeleyo ukuze alungelelanise ukuhamba ngesandla ngokuhambelana nomphunga. Le yindlela yokusebenza kwento ebizwa ngokuba yivalve yokujija ngesandla. Ke ngoko, ayifanelekanga kwiinkqubo zangoku ze-chiller ezifuna ukujikeleza okuzenzekelayo. Izivalo zokwandiswa zihlala zisetyenziswa kwiifriji zangoku zeshishini.

Isetyenziswa ikakhulu kwiifluorine system ezinje ngeR12, R22 kunye neR134a. Esona sixhobo sokugqobhoza esifanelekileyo kwinkqubo yefriji apho iFreon isetyenziswa njengefriji. Ithetha ntoni ivalve yokwandisa ubushushu? Njengoko igama lisitsho, ivalve yokwandisa ubushushu ilawula ukuvulwa kunye nokuvalwa kwesivalo sokwandiswa kobushushu. Inxalenye yeqondo lobushushu lolwandiso lwe-thermal ifakiwe emva kwe-evaporator, ukuze ubushushu begesi yefriji ephuma ngumphunga ekhutshwe kwi-evaporator inokudlula, emva koko uthathe isigqibo sokuba loluphi uhlobo lokuvula nokuvala ubungakanani benxalenye yesixhobo sokurhwaphiliza.

Ngapha koko, i-valve yokunyusa i-thermal lolona hlobo lusetyenziswa kakhulu lwe-valve yokwandisa, kwaye ikwaluhlobo lwevalve yokwandisa ngozinzo olulungileyo. Iindleko zokusetyenziswa kwayo ziphantsi kakhulu. Nangona kunjalo, ii-valves zokwandisa i-thermal zahlulwe zaziindidi ezahlukeneyo, kubandakanya nohlobo lwangaphakathi lokulinganisa. Kwaye ezinye iintlobo, umda wesicelo wahlukile. Kwizikhenkcezisi ezincinci nezincinci, ukusebenzisa ivalve yokwandisa ubushushu ngaphakathi ngaphakathi inokuhlangabezana neemfuno zomphunga zomphunga kunye nayo yonke chiller, kwaye inokugcina imveliso. Ukongeza kwiindleko zokuvelisa, ixabiso kunye neendleko zangaphakathi zokulinganisa ukwanda kwe-thermal ziphantsi.
