Core Design Contradiction:

Use of energy by moving objectVSLoss of energy

Solution Approach 1:

The system changes the operating parameters by using two different refrigerants with distinct vapor pressure characteristics. The first refrigerant operates in the compressive section while the second refrigerant operates in the expansive section, allowing the system to utilize ambient temperature differences more effectively and reduce electrical energy dependency

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The invention replaces the conventional electrical compressor-driven system with a mechanically balanced system where the compressive and expansive forces are均衡ed through the use of two refrigerants with different properties, allowing the system to operate with minimal or no electrical input

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Loss of energy

If conventional air conditioning systems are used, then cooling is achieved, but heat recycling is not performed

Engineering Contradiction:

Improveheat energy wasteVSAvoidenergy efficiency

Core Design Contradiction:

Loss of energyVSProductivity

Solution Approach 1:

The system implements heat recycling by capturing waste heat from the compressive section and utilizing it in the expansive section. The heat expelled during compression is fed back into the system to assist in the expansion process, creating a closed-loop thermal feedback mechanism that improves overall energy efficiency

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The invention merges the cooling and heating functions into a single integrated system. The compressive section and expansive section are thermally coupled, allowing heat transfer between them, so that the waste heat from one section becomes a useful resource for the other section

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 1:

The system is segmented into two distinct sections: a compressive section using the first refrigerant and an expansive section using the second refrigerant. Each section is optimized for its specific function, and the segmentation allows for independent selection of refrigerant properties to achieve desired mechanical advantage ratios

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The mechanical advantage system acts as an intermediary mechanism that couples the compressive and expansive sections. This intermediary device translates the pressure differences generated by the two different refrigerants into useful mechanical work while maintaining system balance

AI summary

Heat is collected by tributary canals formed by the space bounded by the rafters of the roof and by a thermally insulated panel at the bottom and by the roof at the top. The tributary cannels collect and concentrate solar energy that has penetrated the roof. The heat is collected by a plurality of tributary canals, in which solar heat is absorbed. The tributary canals are positioned substantially parallel with a building roofs slope such that the higher ends of the tributary canals are in the proximity of the ridge board of the roof at which a mainstream duct collects hot air arriving through the higher ends of the tributary canals. At the end of the mainstream duct an evaporator box for housing an evaporator is placed with a fan that pulls the hot air from the tributary canals and into the mainstream duct and pushes it onto an evaporator.
