A refrigerated case (20) has a housing containing an interior volume (36) for storing items. Along an air flow path (510) through the case, a refrigerant-to- air heat exchanger (60) has an evaporator section (112) and a reheat section (114). A preconditioning section (110) may be upstream of the evaporator section (112) and the evaporator section is upstream of the reheat section (114). Along a refrigerant flow path (520), the reheat section (114) is downstream of the preconditioning section (110) (if any) and upstream of the evaporator section (112) and an expansion device (62) is between the reheat (114) and evaporator (112) sections.
La présente invention concerne un carter réfrigéré (20) comprenant un boîtier contenant un volume intérieur (36) destiné à ranger des articles. Le long d~une voie (510) de circulation d~air traversant le boîtier, un échangeur thermique réfrigérant-air (60) comporte une section d~évaporation (112) et une section de réchauffage (114). Une section de préconditionnement (110) peut être disposée en amont de la section d~évaporation (112) et la section d~évaporation se trouve en amont de la section de réchauffage (114). Le long d~une voie (520) de circulation de réfrigérant, la section de réchauffage (114) se trouve en aval de la section de préconditionnement (110) (si elle existe) et en amont de la section d~évaporation (112) et un dispositif d~expansion (62) est placé entre les sections de réchauffage (114) et d~évaporation (112).
