Abstract
A compartment ventilating apparatus prevents its indoor louver (22) from being subjected to the formation of dew, and, therefore can prevent the dew built up in its ventilation area in the form of ice, which enables the apparatus to keep a sufficient ventilation area in operation. In the apparatus, an opening portion (3 ) passes through a side wall (2) of a compartment (1). Mounted in the opening portion, (3) are an inner ventilation unit (4) and an outer ventilation unit (5) which is spaced apart from the inner ventilation unit (4).
