Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If air/water aerothermal heat pumps are used for heating, then energy performance coefficient (COP) is improved compared to standard heating systems, but efficiency deteriorates at night or in winter due to weather conditions
Solution Approach 1:
The patent introduces a thermal energy storage tank as an intermediary between the heat pump and the heating system. The heat pump charges the thermal storage tank during periods of high efficiency, and the stored thermal energy is then used during periods when the heat pump efficiency would be low (night or winter), thereby maintaining reliable heating performance while preserving the high COP benefits.
2Reliability
If geothermal heat pumps are used to capture calories from water, then efficiency is improved with greater temperature consistency, but installation cost increases due to aquifer water extraction or surface network creation
Solution Approach 1:
The patent utilizes the swimming pool water as a self-service thermal energy source. The pool water, which naturally maintains relatively consistent temperatures due to its large thermal mass, directly serves as the heat exchange medium for the heat pump, eliminating the need for expensive aquifer extraction systems or surface network installations while providing reliable temperature consistency.
3Loss of energy
If thermal energy management systems are implemented for heating and cooling, then energy efficiency is improved, but device complexity increases due to multiple circuits and equipment
Solution Approach 1:
The patent designs a multi-functional thermal management system where a single heat pump unit serves multiple purposes: heating the swimming pool, heating the thermal storage tank, and providing space heating or cooling for the dwelling. The thermal storage tank also serves dual functions as both a heat source and a heat sink. This universality reduces the need for separate dedicated systems for each function, thereby managing complexity while improving overall energy efficiency.
