<p>A produce display counter (2) is provided with a lower inclined shelf (10) and further vertically separated inclined shelves (14,16) for the display of produce to customers in food outlets. A row of fans (20) is provided underneath the lowermost shelf to draw air from the front of the shelf towards its rear where an air cavity (24) in which is provided a heat exchanger (34) is located. The air is urged into the air cavity and through the heat exchanger which cools the air. The air cavity is provided with baffles (46) and outlet above the lowermost shelf such that cool air flows thereover, and in accordance with the invention, a pair of air conduits (52) is additionally provided in communication with said air cavity such that air that has passed through the heat exchanger is urged upwardly within said conduits which are connected together above one of the vertically separated shelves such that cool air can flow over the vertically separated shelves. A cool air circulation path may thus be set up within the counter, and furthermore the air flow rate over the various shelves within the counter can be adjusted by selecting the baffle size. Produce on shelves other than the lowermost shelf can now be chilled. <IMAGE></p> |
