Solution Overview
Problem
Current air conditioning systems for motor vehicles are prone to refrigerant leakage and are difficult to install, lacking effective measures to limit pressure drops and ensure secure refrigerant fluid circulation.
Innovation Solution
The system incorporates a one-piece support with integrated components such as a compressor, heat exchangers, and pumps, forming a monobloc assembly that includes a primary air conditioning loop and two secondary loops, with internal pipes for fluid communication, and attachment means to the vehicle chassis, reducing the risk of refrigerant leakage and simplifying installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple air conditioning components are distributed and installed separately in the vehicle, then the system allows flexibility in component placement and individual component access, but the risk of refrigerant leakage increases and installation becomes complicated
Solution Approach 1:
The patent combines multiple air conditioning components (compressor, condenser, evaporator, expansion device, distribution block) into a single integrated monobloc assembly. This merging of previously separate components into one unified structure eliminates the need for multiple connection points and refrigerant lines between components, thereby reducing refrigerant leakage risk while simplifying installation to a single unit mounting operation.
2Reliability
If multiple air conditioning components are connected through external pipes and connections, then the system allows modular assembly and component replacement, but pressure drops increase due to multiple connection points and pipe lengths
Solution Approach 1:
By integrating all air conditioning components into a single monobloc assembly with internal fluid passages, the invention eliminates external pipes and multiple connection points. This internal integration of refrigerant flow paths within the unified structure minimizes pressure drops by reducing flow path length and eliminating connection losses, while the components are manufactured as an integrated unit rather than assembled from separate parts.
