Hyperbaric Chamber Passive Cooling Using Pressure Relief Valves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hyperbaric chamber cooling systems are prone to condensation and mold issues, are high maintenance, and pose environmental and health hazards due to their reliance on chillers and chlorofluorocarbon-based coolers, while also being loud and unsanitary.
Innovation Solution
A passive cooling system that uses a series of pressure relief valves to reduce the pressure and temperature of compressed air before it reaches the hyperbaric chamber, eliminating the need for traditional cooling methods by utilizing a compressor, flexible hoses, and a cylindrical cooling unit made from biocompatible materials, which absorbs heat through expansion and does not require additional energy or hazardous substances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If traditional cooling systems (chillers or chlorofluorocarbon-based coolers) are used in hyperbaric chambers, then the temperature can be controlled, but the systems become high maintenance, loud, and potentially hazardous
Solution Approach 1:
The patent removes the traditional cooling system (chiller or chlorofluorocarbon-based cooler) from the hyperbaric chamber and replaces it with a passive cooling mechanism using pressure relief valves. This extraction eliminates the complex, high-maintenance, and potentially hazardous cooling components while retaining the essential temperature control function through a simpler system.
Solution Approach 2:
The cooling system operates passively using the natural pressure differential between the compressor and the chamber. The pressure relief valves automatically regulate the pressure and temperature without requiring external power, control systems, or maintenance, making the system self-regulating and eliminating the need for complex active cooling components.
2Temperature
If chillers are used for cooling, then temperature moderation is achieved, but condensation and mold issues occur
Solution Approach 1:
The patent removes the chiller from the system entirely and replaces it with pressure relief valves that cool the air passively through pressure reduction. This extraction eliminates the source of condensation and mold problems associated with traditional chiller-based cooling systems.
Solution Approach 2:
The patent replaces the mechanical chiller system with a passive pressure relief valve system that uses thermodynamic principles (pressure-temperature relationship) to achieve cooling without the mechanical components that cause condensation and mold.
3Temperature
If chlorofluorocarbon-based coolers are used, then cooling is provided, but environmental and health hazards are introduced
Solution Approach 1:
The patent removes the chlorofluorocarbon-based cooler from the system and replaces it with pressure relief valves that use only air and pressure differential for cooling. This extraction eliminates the harmful chlorofluorocarbon substances while maintaining the cooling function.
Solution Approach 2:
The patent uses a safe, inert atmosphere (compressed air) instead of hazardous chlorofluorocarbon gases. The pressure relief valves regulate the air pressure and temperature without introducing any harmful substances into the chamber environment.
4Temperature
If traditional cooling systems are installed, then temperature control is achieved, but noise levels increase
Solution Approach 1:
The patent removes the noisy mechanical cooling components (chiller motor, compressor, fans) and replaces them with silent pressure relief valves. The passive pressure-based cooling system operates without the mechanical noise generation associated with traditional active cooling systems.

AI summary
A system for cooling a hyperbaric chamber includes a compressor, a first hose, a cooling unit, a second hose, and a hyperbaric chamber. The first hose fluidly connects the compressor to the cooling unit, and the second hose fluidly connects the cooling units to the hyperbaric chamber. Compressed air from the compressor travels through a first pressure relief fitting and a second pressure relief fitting, where the compressed air is depressurized according to the system requirements. During the depressurization, the compressed air cools down because of the depressurization and creates a comfortable environment within the hyperbaric chamber.
