Le banc CRD500 permet l\u2019\u00e9tude d\u2019un cycle frigorifique.<\/p>\n
Le banc est compos\u00e9 des \u00e9l\u00e9ments standards d\u2019un circuit frigorifique.\u00a0 Le compresseur va tout d\u2019abord \u00e9lev\u00e9 la pression et la temp\u00e9rature du gaz (R134a). le condenseur \u00e0 eau va ensuite transformer ce gaz haute pression en liquide haute pression. Les \u00e9l\u00e8ves visualisent la transformation car le fluide frigorig\u00e8ne se condense entre la calandre en verre et le serpentin de refroidissement.<\/p>\n
Le liquide haute pression va ensuite \u00eatre stock\u00e9 dans une bouteille puis \u00eatre envoy\u00e9 vers les d\u00e9tendeurs. Celui-ci va changer l\u2019\u00e9tat du fluide, il va passer d\u2019un liquide haute pression \u00e0 un liquide basse pression. Ce liquide basse pression est maintenant dans l\u2019\u00e9vaporateur et il va puiser son \u00e9nergie sur le serpentin \u00e0 eau (et donc le refroidir) ou sur l\u2019air suivant l\u2019\u00e9vaporateur s\u00e9lectionn\u00e9. Les \u00e9l\u00e8ves visualisent la transformation (pour l\u2019\u00e9vaporateur \u00e0 eau) car le fluide frigorig\u00e8ne s\u2019\u00e9vapore entre la calandre en verre et le serpentin de refroidissement. A la sortie de l\u2019\u00e9vaporateur, le fluide est sous forme vapeur \u00e0 basse pression, il va traverser une bouteille anti coup de liquide et \u00eatre comprim\u00e9 de nouveau par le compresseur.<\/p>\n
La conception robuste de cet \u00e9quipement le rend parfaitement adapt\u00e9 pour une utilisation en milieu scolaire.<\/p>\n
Sa structure en aluminium anodis\u00e9e sur roues lui conf\u00e8re une tr\u00e8s grande robustesse ainsi qu\u2019une grande souplesse d\u2019int\u00e9gration dans vos locaux. La fabrication de cet \u00e9quipement r\u00e9pond \u00e0 la directive machine\u00a0 europ\u00e9enne<\/p>\n","protected":false},"excerpt":{"rendered":"
