Existing heating systems, such as heat pumps and oil/gas heating systems, face challenges in generating flow temperatures suitable for radiant heating elements, requiring extensive renovations and high costs for retrofitting, while standalone systems lack compatibility with existing systems and are inefficient in energy use.
Innovation Solution
A high-pressure pump driven by an electric motor generates heat through a hydraulic orifice with back pressure, utilizing friction and kinetic energy to increase fluid temperature, integrated with a pressure-relief chamber and optional expansion chamber, and optionally assisted by a hydraulic motor, to achieve temperatures comparable to conventional systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If heat pumps are used for heating buildings, then energy efficiency is improved, but flow temperature is reduced making them incompatible with conventional radiant heating systems
Solution Approach 1:
The patent combines a heat pump system with a hydraulic heating system in a hybrid configuration. The heat pump provides efficient heating at lower temperatures while the hydraulic system with friction heating elements supplements the heat output to achieve higher flow temperatures compatible with radiant heating elements like underfloor heating.
Solution Approach 2:
The patent introduces a hydraulic circuit with friction heating elements as an intermediary between the heat pump and the heating circuit. This intermediary component converts mechanical energy from the pump into thermal energy through friction, raising the fluid temperature to levels suitable for radiant heating systems.
2Use of energy by moving object
If existing buildings are converted to heat pumps, then energy efficiency is improved, but extensive renovations and system modifications are required increasing costs
Solution Approach 1:
The hydraulic heating system is designed to be compatible with both conventional radiant heating systems and heat pump systems. The same hydraulic circuit with friction heating elements can supplement either system, making it a universal solution that works across different building types and heating system configurations without requiring extensive renovations.
3Temperature
If standalone hydraulic heating systems are used, then high flow temperatures are achieved, but compatibility with existing heating systems is lost
Solution Approach 1:
The patent merges the standalone hydraulic heating system with existing heating systems through a hybrid configuration. The hydraulic circuit with friction heating elements is integrated alongside conventional heat exchangers, allowing the system to achieve high flow temperatures while maintaining compatibility with existing radiant heating elements and distribution systems.
