Abstract

UNA UNIDAD DE CALENTAMIENTO (10) COMPRENDE UNA SUPERFICIE (12) CALENTABLE, QUE TIENE POR LO MENOS UNA REGION (30) DELA SUPERFICIE CALENTABLE REVESTIDA O SINO PROVISTA DE UNA CAPA (33) QUE TIENE UN MATERIAL TERMOCROMICO EN CANTIDAD SUFICIENTE PARA AFECTAR AL COLOR DE LA CAPA PERCIBIDO. EL MATERIAL TERMOCROMICO PRESENTA UN LONGITUD DE ONDA LIMITE DE ABSORCION, QUE CAMBIA REVERSIBLEMENTE CON LA TEMPERATURA EN EL INTERVALO DE 20-400 (GRADOS) C POR LO MENOS. LA LONGITUD DE ONDA LIMITE DE ABSORCION ES POR LO MENOS 540 NM A 20 (GRADOS) C Y AUMENTA PROGRESIVAMENTE HASTA 700 NM A 400 (GRADOS) C. TAL UNIDAD DE CALENTAMIENTO PUEDE PROPORCIONAR UNA INDICACION VISUAL DE SI LA SUPERFICIE CALENTABLE ESTA O NO ESTA TODAVIA CALIENTE UNA VEZ QUE SE HA DESCONECTADO LA CORRIENTE. MATERIALES TERMOCROMICOS UTILES SON CD(S1-XSEX) Y (ZN1-YMNY)O.
