Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heating and cooling systems in buildings suffer from inefficiencies due to mismatched intake and discharge temperatures, leading to significant thermal energy loss and waste, especially in large facilities with multiple systems operating independently.
Innovation Solution
An elongate thermal gradient header system that progressively varies in temperature from hot to cold, allowing multiple heating and cooling systems to draw fluid at optimal intake temperatures and discharge back at optimal temperatures, thereby optimizing energy transfer and reducing waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple heating and cooling systems operate independently with individualized optimization, then each system achieves its own efficiency, but cumulative thermal energy loss increases significantly
Solution Approach 1:
The patent combines multiple independent heating and cooling systems into a unified thermal network sharing a common header. Systems are interconnected through the header, allowing thermal energy to be exchanged between systems rather than being wasted. This merging enables heat from one system to serve another system's needs, reducing cumulative energy loss while maintaining individual system performance.
Solution Approach 2:
The common header serves multiple functions simultaneously: it acts as a thermal energy source for heating systems, a heat sink for cooling systems, and a redistribution network for thermal energy. The header is designed to accommodate various temperature zones, enabling it to serve different system requirements from a single multi-functional structure.
2Device complexity
If heating and cooling systems use fixed temperature sources, then system design is simplified, but thermal energy waste increases due to temperature mismatch
Solution Approach 1:
The header is designed with spatially varying temperature zones along its length, creating different thermal characteristics at different locations. This local quality variation allows systems to draw thermal energy at their optimal temperatures without requiring complex individual temperature control for each system, as the header naturally provides the required temperature distribution.
Solution Approach 2:
The thermal characteristics of the header are made dynamic through continuous thermal gradients that can adapt to varying system demands. The header responds to changing thermal loads by naturally redistributing thermal energy, with temperature distribution adjusting based on real-time system requirements rather than maintaining fixed temperatures.

AI summary
An apparatus and method for increasing efficiency of heating/cooling systems in buildings and other facilities. An elongate pipe filled with water or other fluid medium forms a thermal gradient header having temperature zones that are progressively warmer towards one end and cooler towards the other. The heating/cooling systems are connected to the header so as to draw circulating fluid from zones that are closest in temperature to the optimal intake temperature of each system, and to discharge fluid back to the header at zones that are closest to the temperature to the optimal output temperature of each system. The heating/cooling systems may be, for example, air conditioning systems, water heating systems, ice making systems, and so on; the facility may be a single building or comprise multiple buildings. The pipe forming the thermal gradient header may be routed back and forth in the facility to define a series of legs at different temperatures, with the intake and output lines of each system being connected to that leg having the temperature closest to optimum. Additional lines and control valves may enable the systems to draw from/discharge to different legs under different operating conditions, such as at different seasons. The system maximizes efficiency by allowing each system to take advantage of the thermal output of other systems. A boiler or other source of makeup heat may be connected to the thermal gradient header if necessary, and any excess heat may be supplied from the header a thermal ground field for later use or may be rejected as necessary.
