Imbangela eyinhloko yokuvinjelwa yiqhwa ngaphambi kwe-expansion valve

Ukuvinjelwa yiqhwa ngaphambi kwe-valve yokunweba kungenye yezinkinga ezivame kakhulu nezibucayi zokunganele kokuhlinzekwa ngoketshezi ezinhlelweni zokupholisa umoya. Uma kuvela ukuvinjelwa yiqhwa, i-refrigerant ngeke ihlinzekwe, i-evaporator izoba "engondliwe", nomphumela wokupholisa uzobuthakathaka ngokushesha. Kunezizathu ezintathu eziyinhloko zokwakheka kokuvinjelwa yiqhwa:

(1) Umswakama omningi ku-refrigerant: Uma okuqukethwe umswakama ku-refrigerant kudlula izinga elijwayelekile, ngesikhathi i-expansion valve ihlehlisa futhi iphola, umswakama uzokwakha amakristalu eqhwa futhi uvimbe imbobo ye-valve.

(2) Izinga lokushisa eliphansi kakhulu lokubilisa: Uma ingcindezi ephansi yesistimu iphansi kakhulu, i-refrigerant izobila futhi iphole kusengaphambili ngaphambi kwe-expansion valve, iqhwa umswakama ube yiqhwa.

(3) Isihlungi esivinjelwe: Isihlungi esivinjelwe sizokwehlisa ingcindezi yoketshezi olungena, okubuye kubangele ukuthi i-refrigerant ibile futhi iqhwa kusengaphambili.

Ngenkathi okuqukethwe kokunisela kwe-refrigerant kulawulwa, ingcindezi yesistimu igcinwa ijwayelekile, futhi ifilitha ihlanzwa njalo, ukuvinjwa kweqhwa kungagwenywa kahle, kuqinisekisa ukusebenza okuhle kwesistimu.
