Vertical-Mount RV Air Conditioner to Eliminate Roof Leak Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing HVAC systems mounted on the roof of recreational vehicles (RVs) are prone to water leakage due to seal degradation, which can lead to interior moisture issues and reduced air conditioning performance.
Innovation Solution
The HVAC system is mounted on a vertical surface of the RV, utilizing a frame mount and brackets to pivot into position, with a base pan and air shroud housing the mechanical components, ensuring drainage and easy access while minimizing noise and corrosion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the HVAC system is mounted on the roof of the RV, then the air conditioning performance is maintained, but water leakage occurs due to seal degradation
Solution Approach 1:
The patent transitions the mounting location from the horizontal roof surface to the vertical sidewall of the RV. This dimensional change eliminates water accumulation issues inherent in flat roof surfaces and removes the HVAC system from the leakage-prone roof aperture area, while maintaining air conditioning functionality through proper ducting configuration
2Ease of manufacture
If the HVAC system is mounted on the roof, then installation is straightforward, but leakage paths are created through mounting holes
Solution Approach 1:
The patent extracts the HVAC system from the roof mounting location and relocates it to the vertical sidewall. This separation removes the source of leakage (mounting holes in the roof) from the system configuration, eliminating the leakage path while preserving the essential air conditioning function through alternative air intake and exhaust arrangements
3Object-affected harmful factors
If the HVAC system is positioned to eliminate leakage paths, then water leakage is reduced, but noise from the system increases
Solution Approach 1:
The patent introduces vibration isolation elements and acoustic insulation materials as intermediary components between the HVAC system and the RV structure. These intermediaries absorb and dampen vibrations and noise generated by the compressor and fan, preventing their transmission to the vehicle body while allowing the system to operate in the optimized vertical sidewall position

Function Achieved in This Case
This configuration reduces water leakage paths, maintains air conditioning performance, and provides easy installation and serviceability, while controlling condensation and exhaust air movement.
Implementation Method 1
the frame having at least one curved edge, the at least one curved edge engaging a corresponding edge of a frame mount and allowing pivoting motion of the frame relative to the frame mount
Implementation Method 2
By positioning the HVAC on a vertical surface, gravity works to move water downward and away from the HVAC system rather than allowing it to stagnate
Data Source
AI summary
The present embodiments relate to an HVAC system which is externally mounted on a vertical surface of an RV, truck or bus. The desire is to eliminate, or at least substantially reduce, a potential leakage path wherein water may sit on an upper surface of a vehicle and due to seal degradation over long periods of time, may find a pathway in through the roof of the vehicle and to an interior thereof. By positioning the HVAC on a vertical surface, gravity works to move water downward and away from the HVAC system rather than allowing it to stagnate in an area around potential apertures through the outer skin or outer surface of the vehicle.
