Abstract

Systemes ameliores de transfert de chaleur a deux phases permettant d'absorber la chaleur de l'energie solaire radiante, et de transferer cette chaleur vers une substance a chauffer. Le fluide de circulation est appele refrigerant. Les systemes de l'invention possedent la propriete decisive d'autoregulation. Le terme autoregulation est utilise pour decrire la capacite d'un systeme de transfert de chaleur a deux phases d'assurer automatiquement qu'au moins les quatres conditions de fonctionnement interne citees ci-apres soient remplies pour toutes les conditions exterieures pour lesquelles ce systeme est concu: 1) le refrigerant (2) entrant dans l'absorbeur collecteur (1) existe exclusivement dans sa phase liquide et possede un debit suffisamment important pour maintenir la quantite de chaleur de la portion evaporee du refrigerant (3) sortant de l'absorbeur collecteur (1) en-deca d'une limite superieure positive predeterminee; 2) la vapeur du refrigerant (9) entrant dans le condenseur (8) est maintenue a l'etat sec; 3) la quantite de refrigerant liquide d'appoint dans le condenseur (8) est suffisamment petite pour maintenir la surface de condensation effective du condenseur au-dessus d'une limite superieure positive predeterminee; et 4) la valeur absolue de la difference entre la temperature de la vapeur saturee (3) sortant de l'absorbeur collecteur (1) et la temperature de la vapeur saturee (9) du refrigerant entrant dans le condenseur (8) est maintenue en-deca d'une limite superieure predeterminee.
