摘要： A sanitizer has substrates which are coated with an optically-activated nanomaterial TiO2 coating for cleaning air which comes into contact with the surfaces of the coating. UV LED light sources are arranged to emit light to be incident on the surfaces to activate the coatings. There is a large surface for impingement of air on the coatings due to a grille arrangement of the substrates, and the LED-emitted UV light being incident at acute angles on the grille honeycomb structure.

摘要： A refrigerated merchandiser including a case that defines a product display area and an access opening. The case has an air inlet and an air outlet, and a passageway fluidly connects the air inlet with the air outlet to direct a refrigerated airflow across the customer access opening in the form of an air curtain. The merchandiser also includes shelves that are coupled to the case. Each shelf includes an inlet, an outlet, a fan unit disposed in the shelf, and a heat exchanger. The fan unit is in communication with the passageway to draw air through the inlet to direct a portion of the airflow through the shelf toward the outlet. The heat exchanger is disposed in the shelf to cool the airflow in the shelf to provide independent zone cooling to a predetermined region of the product display area.

摘要： A refrigerated merchandiser includes a case defining a product display area and having a base, a lower flue, a first air passageway, and a second air passageway. The first air passageway and second air passageway are in fluid communication with the lower flue and with the product display area. The refrigerated merchandiser also includes an evaporator positioned in the first air passageway and a fan assembly positioned in the base in fluid communication with the lower flue to generate an airflow. A fan plenum into which the fan assembly is disposed includes an airflow divider to direct a first portion of the airflow to the first air passageway and to direct a second portion of the airflow to the second air passageway. The proportion of air between the first portion and the second portion is a function of the position and geometry of the airflow divider.

摘要： A cooling unit including a base group, a rear wall group and an upper group, defining a cooling chamber from below, the back and above, and are provided at least in part with components of a cooling device and which have a multi-layered structure with a flow channel arrangement embodied therein. In the base group as well as the rear wall group and the upper group intermediate spaces are formed between respective layers as parts of the flow channel arrangement and the lower intermediate space formed in the base group is, on the rear side, in fluidic connection for the circulating air with a lower section of the vertical intermediate space formed in the rear wall group and the upper intermediate space formed in the upper group is, on the rear side thereof, in fluidic connection for the circulating air with an upper section of the vertical intermediate space formed in the rear wall group and an evaporator or another heat exchanger of the cooling device is arranged in the vertical intermediate chamber for generating cooling air. At least one ventilator, designed in particular as a radial ventilator, is arranged at least in the vertical intermediate spaces in order to guide the airflow through the intermediate spaces which are the measures allowing an advantageous cooling function.
