I-ValveVe ye-Expension iyingxenye ebalulekile yohlelo lweqandisini, imvamisa ifakwe phakathi kwesilinda sokugcina uketshezi kanye ne-evaporator. The expansion valve makes the liquid refrigerant at medium temperature and high pressure become wet steam at low temperature and low pressure through its throttling, and then the refrigerant absorbs heat in the evaporator to achieve the refrigeration effect. I-valve yokwanda ilawulwa i-valve igeleza ngoshintsho olukhulu ngokuphela kokuphela kwe-evaporator ukuvikela ukwenziwa kabusha kwendawo ye-evaporator kanye nento yokungqongqoza isilinda
Kalula nje, i-valve yokwanda ihlanganiswa nomzimba, amazinga okushisa azwayo ne-Blast Tube
Isimo esisebenza kahle se-Valve Sokunwebeka kufanele kube ukushintsha ukuvulwa ngesikhathi sangempela futhi silawule izinga lokugeleza ngokushintsha komthwalo we-evaporator. Kepha eqinisweni, ngenxa ye-hysteresis yokudluliswa kokushisa endaweni yokushisa yokuzwa okuzwakalayo, impendulo ye-valve yokwanda ihlala inesigamu se-hit slow. Uma sidweba umdwebo we-time-flow ye-valve yokwanda, sizothola ukuthi akuyona ijika elibushelelezi, kodwa umugqa we-wavy. Izinga le-valve yokwanda liboniswa ekuphumeni kwegagasi. Ubukhulu bokuphakama, okuhamba kancane ukusabela kwe-valve kanye nekhwalithi embi kakhulu
