Title
(EN) THERMAL SENSING BULB CONTAINING A BALLAST MATERIAL FOR AN EXPANSION VALVE
(FR) AMPOULE DE DÉTECTION THERMIQUE CONTENANT UN MATÉRIAU DE BALLAST POUR UNE SOUPAPE D'EXPANSION
Abstract
(EN)
A thermal sensing bulb (102) for an expansion valve (104) in a refrigerant system, the bulb containing a ballast material (108), the ballast material including alumina. More particularly, the ballast material (108) includes alpha alumina, which may be in the form of a plurality of discrete particles having a desired surface area, particle size, and/or particle size distribution.
(FR)
L'invention porte sur une ampoule de détection thermique (102) pour une soupape d'expansion (104) dans un système réfrigérant, l'ampoule contenant un matériau de ballast (108), le matériau de ballast comprenant de l'alumine. Plus particulièrement, le matériau de ballast (108) peut comprendre de l'alumine alpha, qui peut se présenter sous la forme d'une pluralité de particules séparées ayant une surface de contact, une taille de particule et/ou une distribution granulométrique souhaitées.
