Solution Overview

Problem

Current air cooling systems for large premises, such as those on ships and offshore platforms, face challenges in maintaining uniform temperature distribution due to airflow obstruction by stored foodstuffs, occupy excessive space, and are cumbersome for maintenance, especially when installed in corners.

Innovation Solution

A compact cooling system design where air is sucked in from the lower part, passes vertically through a mid-located cooling battery, and is expelled horizontally under the ceiling, utilizing a thinner middle and lower section to allow closer storage and improved airflow, with optional inclined planes for weight distribution and deflector elements for directed air flow, and defrost resistors in tubes for efficient maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of repair

If air coolers are placed in the middle of a wall for maintenance access, then ease of repair is improved, but the footprint and space occupancy increase

Engineering Contradiction:
Improvemaintenance accessVSAvoidfootprint
Core Design Contradiction:
Ease of repairVSArea of stationary object

Solution Approach 1:

The air cooler is repositioned from a wall-mounted configuration to a corner installation configuration, utilizing the third dimension (corner space) rather than occupying wall area. This allows maintenance access from the front while installing in corners where traditional wall-mounted units cannot be placed, thus resolving the contradiction between maintenance accessibility and space occupancy.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The air cooler adopts an asymmetric design with different thicknesses for different parts: the upper part (containing the fan) is thicker, while the middle and lower parts are thinner. This asymmetric configuration optimizes both maintenance access and space utilization, allowing the unit to be installed in corners while maintaining adequate access for service.

Inventive Principle:
Principle #4Asymmetry

2Reliability

If fans are placed at the same height as the refrigeration battery, then the cooling function is improved, but the thickness and volume of the air cooler increase

Engineering Contradiction:
Improvecooling functionVSAvoidair cooler volume
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The air cooler employs an asymmetric vertical configuration where the fan is positioned in the upper part at a different height than the refrigeration battery in the middle part. This asymmetric arrangement maintains effective cooling function while reducing the overall thickness and volume of the unit compared to conventional symmetric designs where fan and battery are at the same height.

Inventive Principle:
Principle #4Asymmetry

3Area of stationary object

If air coolers are installed in corners for space optimization, then space occupancy is reduced, but maintenance access becomes difficult

Engineering Contradiction:
Improvespace occupancyVSAvoidmaintenance access
Core Design Contradiction:
Area of stationary objectVSEase of repair

Solution Approach 1:

The air cooler is specifically designed for corner installation, utilizing the corner space (a three-dimensional configuration) rather than requiring wall-mounted placement. The unit's asymmetric design with thinner middle and lower parts allows it to fit in corners while the front face remains accessible for maintenance, thus resolving the contradiction between space optimization and maintenance accessibility.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Power

If traditional air coolers are used with horizontal airflow, then the cooling capacity is maintained, but temperature uniformity in the room deteriorates when foodstuffs are stored to maximum height

Engineering Contradiction:
Improvecooling capacityVSAvoidtemperature uniformity
Core Design Contradiction:
PowerVSTemperature

Solution Approach 1:

The air cooler inverts the traditional horizontal airflow configuration by expelling cold air upward from the upper part. This inverted vertical airflow pattern allows the cold air to descend along the walls and distribute more uniformly throughout the room, especially when foodstuffs are stored to maximum height, thus improving temperature uniformity while maintaining cooling capacity.

Inventive Principle:
Principle #13The other way round (Inversion)

AI summary

The invention concerns an air cooling system comprising a cooling battery traversed by a vertical air stream and at least one fan disposed above the cooling battery. The fan discharges the cooled laminar air stream in the top part of the system, and said air stream is drawn in in the bottom part. The thicknesses of the middle parts comprising the cooling battery and of the bottom part comprising a suction grille are less than that of the top part containing the at least one fan. In this way, the middle and bottom parts are thinner than the top part, thus allowing goods to be stored closer to the cooling system.
