Solar Panel Fluid Preheating for Desalination Energy Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for dividing a fluid into two parts, such as seawater desalination, suffer from significant energy loss and require additional energy inputs, making them inefficient and costly.
Innovation Solution
A method and device that utilize a photovoltaic solar panel to preheat a fluid before it enters a treatment device, where the fluid is divided into two parts, with the heat from the treated fluid being transferred back to the incoming fluid, reducing the energy needed for heating and maintaining the solar panel at an optimal temperature for efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a photovoltaic solar panel is used to heat fluid for treatment, then the fluid can be heated to required temperature, but the photovoltaic panel efficiency decreases due to high temperature
Solution Approach 1:
The system separates the heating function from the photovoltaic energy conversion function. The photovoltaic panel generates electricity while a dedicated heating element (or separate thermal system) provides the thermal energy for fluid treatment, allowing both functions to operate at optimal conditions independently
Solution Approach 2:
An intermediary thermal transfer system is introduced between the photovoltaic panel and the fluid treatment process. This intermediary allows heat to be transferred to the fluid without directly heating the photovoltaic panel, using heat exchangers or thermal transfer fluids that decouple the thermal and electrical functions
2Productivity
If additional heating energy is provided to divide fluid into two parts, then the fluid treatment process can be completed, but energy consumption increases
Solution Approach 1:
The system performs preliminary heating of the fluid using waste heat or pre-conditioning before the main treatment process. By preheating the fluid in advance, the energy required during the actual fluid division and treatment is reduced, improving overall energy efficiency
Solution Approach 2:
The system recovers and reuses waste heat from the fluid treatment process. Heat exchangers capture thermal energy from treated fluid streams and redirect it to preheat incoming fluid or for other useful purposes, minimizing energy waste and reducing total energy consumption
3Loss of energy
If heat is transferred from treated fluid to incoming fluid, then energy loss is minimized, but the system complexity increases
Solution Approach 1:
The heat transfer system operates continuously to recover energy from outgoing treated fluid and transfer it to incoming fluid. This continuous thermal exchange minimizes energy loss throughout the operation, with heat exchangers maintaining thermal coupling between process streams without requiring intermittent adjustments

Implementation Method 1
by means of the photovoltaic solar panel solar energy is converted into electrical energy, which electrical energy is at least partly used to operate at least partly the fluid treatment device
Implementation Method 2
before entering the fluid treatment device the flow of relatively cold fluid is being preheated by the relatively warm photovoltaic solar panel, the relatively warm flow of the first fluid part and the relatively warm flow of the second fluid part
Implementation Method 3
by heating the flow of fluid in the fluid treatment device, a part of the flow of fluid is evaporated into a vapor forming the first fluid part
