Title (EN) REFRIGERATION METHOD AND APPARATUS USING HEAT
(FR) PROCEDE ET DISPOSITIF DE REFRIGERATION UTILISANT LA CHALEUR
Abstract: front page image
(EN)Working fluid from an evaporator (110) of a vapor-compression mechanical refrigeration system is heated (114) prior to compression (120) and condensation (102). Such heating reduces the total work that must be performed on the fluid to increase its pressure prior to introduction to the high pressure side of the refrigeration system. Heating means (114) disclosed by the present invention include solar collectors (400), industrial waste heat exchanges and flue gas heat exchanges (Figs. 5-7). These heating means may also provide the mechanical or electric power required to accomplish any mechanical compression used in the present invention.
(FR)Le fluide de travail en provenance d"un evaporateur (110) d"un systeme de refrigeration mecanique par compression de vapeur est chauffe (114) avant la compression (120) et la condensation (102). Un tel chauffage reduit le travail total devant etre execute sur le fluide pour augmenter sa pression avant son introduction dans le cote haute pression du systeme de refrigeration. Des moyens de chauffage (114) decrits dans la presente invention comprennent des collecteurs solaires (400), des echangeurs de chaleur des dechets industriels et des echangeurs de chaleur des gaz de fumee (fig. 5-7). Ces moyens de chauffage peuvent aussi fournir l"energie mecanique ou electrique requise pour executer toute compression mecanique utilisee dans la presente invention.
