Device for air conditioning a room with an air conditioner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioning systems for renovated buildings are too complex and inefficient for low-energy houses, especially in multi-story buildings, due to high distribution line losses and the need for central heating and hot water concepts, which are not suitable for the marginal heating outputs required in modern, insulated structures.
Innovation Solution
A prefabricated unit combining a Peltier element, a countercurrent heat exchanger, and a control/regulating device, powered by a photovoltaic system, is integrated into a building's facade or window, allowing for efficient heating and cooling with minimal effort and energy self-sufficiency, using a Peltier element between room and outside air ducts to manage thermal energy distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a central heat pump with conventional distribution system is installed, then heating and cooling can be provided for multiple rooms, but distribution line losses are high and the system becomes too complex for low-energy houses
Solution Approach 1:
The patent divides the central heating system into individual decentralized air conditioning units for each room. Each unit contains its own Peltier element and heat exchanger, eliminating the need for complex distribution pipes and reducing energy losses in heat transfer. This segmentation allows each room to be independently controlled and heated/cooled without relying on a central system.
Solution Approach 2:
The patent replaces the conventional mechanical heat pump system with compression-based heat transfer with a Peltier element-based thermoelectric system. The Peltier element uses electrical current to directly transfer heat between indoor and outdoor air, eliminating the need for compressors, refrigerants, and complex mechanical distribution infrastructure.
2Device complexity
If a Peltier heat pump is used for room temperature control, then heating and cooling can be achieved with simple structure, but the heating output is limited to marginal values suitable only for low-energy houses
Solution Approach 1:
The patent combines the Peltier element with a heat exchanger that utilizes both indoor and outdoor air flows in a counterflow arrangement. This merging of components creates a system where the Peltier element's limited heating output is amplified by efficient heat exchange with the outdoor air, enabling the system to meet the heating demands of low-energy houses while maintaining structural simplicity.
3Adaptability or versatility
If a central heat pump system is installed in renovated buildings, then existing buildings can be upgraded, but the system becomes too complex and inefficient for modern low-energy house requirements
Solution Approach 1:
The patent implements decentralized air conditioning units that can be independently installed in each room of renovated buildings. This segmentation eliminates the need for extensive retrofitting of central distribution systems while providing efficient, localized climate control that adapts to the specific thermal requirements of low-energy house renovations.
