Solution Overview
Problem
Existing thermotechnical systems require three wall openings for installation, increasing complexity and size, which hinders efficient use and retrofitting of heat pump systems with ventilation units.
Innovation Solution
Combining the air supply and discharge ducts of both the heat pump and ventilation devices into a single duct unit, using either the air supply or discharge duct of the heat pump as a common outlet, reducing the number of wall openings to two and allowing for seamless integration of a ventilation unit into existing heat pump systems without additional openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate wall openings are provided for air supply and air discharge ducts of both devices, then airflow paths are clearly defined, but the number of wall openings increases to three, increasing installation complexity and system size
Solution Approach 1:
The patent combines multiple ducts (air supply duct of first device, air supply and discharge ducts of second device) into a single common duct unit that opens through two wall openings instead of three separate openings. This merging reduces installation complexity while maintaining functional separation through internal duct arrangement and airflow direction control.
Solution Approach 2:
The common duct unit serves multiple functions simultaneously: it acts as both air supply and air discharge pathway for different devices, accommodates multiple ducts within a single structural opening, and provides a unified interface for wall penetration while maintaining separate airflow paths internally.
2Device complexity
If a common duct unit is used for air supply and discharge ducts, then the number of wall openings is reduced to two, simplifying installation, but the ducts are arranged close together which may cause pneumatic short circuits
Solution Approach 1:
The patent nests multiple ducts within the common duct unit, arranging the air supply duct and air discharge duct in a nested or closely integrated configuration. This allows space-efficient arrangement within the constrained wall opening while maintaining functional separation through proper duct positioning and sealing.
Solution Approach 2:
The patent applies different spatial arrangements to different sections of the ducts within the common duct unit. The air supply duct and air discharge duct are positioned at specific locations and orientations (e.g., opposite walls or at different heights) to ensure adequate separation and prevent pneumatic short circuits while maintaining the compact overall structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration simplifies installation, reduces system size, and enables efficient heat recovery and ventilation by using existing heat pump systems with minimal modifications, while maintaining airflow integrity and allowing for heat reuse during operation.
Implementation Method 1
the first device, in this case the heat pump, is used to raise heat from the air surrounding the building from a low temperature level to a higher temperature level for use in the building
Implementation Method 2
the second device, i.e. the ventilation device, is used on the other hand for forced ventilation of the building, with fresh ambient air being sucked in via the air supply duct and used air being discharged to the environment via the air discharge duct
Implementation Method 3
Air thus flows into the building, both into the air supply duct of the first device and into the air supply duct of the second device
