Abstract

The refrigerated sales display arrangement has air humidifier in the ventilating circuit. The air humidifier is readily regulated and ensures extremely fine dispersion of the water. The air humidifier (10) incorporates an ultrasonic vibrator (22) held within a water container (20). In the air circuit is fitted a fan upstream of the water container (20). Downstream of the water container is fitted a contracting rising channel which terminates at the top in the refrigerator display area (14).
