Refrigerated Display Layout for Bottom-Area Cooling and Shelf Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refrigerated sales furniture of the front access type has limited space for presenting goods due to inefficient cooling of the bottom area, where the fan and evaporator placement restricts the available space and cooling efficiency.
Innovation Solution
A refrigerated sales furniture design with an air suction channel, fan, and cold air channel configuration that directs cold air from the back to the bottom area, maximizing space usage and ensuring efficient cooling across the entire presentation space, including the bottom area, by positioning the fan behind the bottom area and using air guiding shelves to direct cold air downward.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the fan and evaporator are arranged underneath the lowest goods presentation shelf, then the cooling function is achieved, but the available space for presenting goods is reduced
Solution Approach 1:
The patent relocates the fan and evaporator from the horizontal plane (underneath the lowest shelf) to the vertical rear space (behind the bottom area), utilizing the depth dimension of the furniture. This allows the goods presentation space to extend fully to the rear wall, maximizing horizontal display area while maintaining cooling functionality through the rear air suction channel and cold air channel configuration.
2Device complexity
If the fan and evaporator are arranged underneath the lowest goods presentation shelf, then the cooling system is compact, but the bottom area cooling efficiency is insufficient
Solution Approach 1:
The patent implements a dedicated lower cold air channel portion that specifically targets the bottom area for cold air delivery, while separate air channels serve the upper portions. The rear air suction channel is positioned to draw air from the bottom front end portion, creating a localized cooling circuit optimized for the bottom area. This ensures reliable cooling of the bottom region without compromising the overall system compactness.
3Area of stationary object
If the fan is arranged behind the bottom area, then the goods presentation space is maximized, but the air channel configuration becomes more complex
Solution Approach 1:
The air channel system is divided into distinct segmented components: a rear air suction channel portion extending vertically behind the bottom area, a lower air pressure channel portion extending horizontally in front of the rear suction channel, and a lower cold air channel portion connecting these elements. This segmentation allows each channel to be optimized for its specific function while maintaining overall system manageability and maximizing goods presentation space.
