Innovation Solution
An air conditioning system that uses water as a refrigerant, eliminating the need for a condenser by employing a vacuum chamber, ultrasonic mist maker, and closed-circuit chilled water module with fan coil units, allowing for efficient cooling without external ductwork or chemical refrigerants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an outdoor condenser is used in conventional air conditioning systems, then cooling function is achieved, but aesthetic appearance deteriorates and noise and vibrations increase
Solution Approach 1:
The patent extracts and eliminates the outdoor condenser component from the air conditioning system. By using water as a refrigerant that evaporates at atmospheric pressure, the system removes the need for a separate condensing unit, thereby eliminating the source of noise and vibrations while improving aesthetic appearance.
Solution Approach 2:
The patent changes the physical parameters of the refrigerant from conventional chemicals to water, and changes the operating pressure from high pressure to atmospheric pressure. This allows the phase change to occur naturally without mechanical compression and condensation equipment, reducing noise and vibration.
2Productivity
If chemical refrigerants are used, then cooling efficiency is achieved, but environmental harm and safety issues increase
Solution Approach 1:
The patent uses water, an abundant and environmentally benign substance, as the refrigerant instead of expensive and harmful chemical refrigerants. Water is safely disposed of through evaporation, eliminating environmental contamination risks while maintaining cooling efficiency through phase change.
Solution Approach 2:
The patent creates a safe operating environment by using water as the refrigerant, which is non-toxic, non-flammable, and environmentally inert. This eliminates the harmful effects associated with chemical refrigerants while maintaining effective heat transfer properties.
3Ease of operation
If an outdoor condenser is installed, then cooling function is provided, but installation cost and space requirement increase
Solution Approach 1:
The patent merges the refrigerant storage, circulation, and phase change functions into a single integrated water-based system. The water reservoir serves multiple purposes: storing the refrigerant, allowing evaporation for cooling, and eliminating the need for separate condenser equipment, thereby reducing installation complexity and space requirements.
Solution Approach 2:
The water-based system performs multiple functions: it acts as the refrigerant, the heat transfer medium, and the working fluid for phase change cooling. This multi-functionality eliminates the need for dedicated condenser equipment and ductwork, simplifying installation and reducing space requirements.

AI summary
An air-conditioner system includes a vacuum chamber with a mist maker in communication with water to create mist within the vacuum chamber; a vacuum pump to maintain a vacuum within the vacuum chamber; a discharge outlet extending from the vacuum pump to discharge vapor; a nozzle attached to a water source; a circulating pump in fluid communication with the water within the vacuum chamber via an outlet; a cooling coil connected to the circulating pump to direct water from the circulating pump to the vacuum chamber; and an insulated chamber with a blower to blow cooled air to a building; the cooled air is cooled via the multi-row cooling coil positioned within the insulated chamber. Besides the cooling system, this invention integrates itself very well with the heating system as shown in schematics.
