Solution Overview
Problem
Conventional heat exchange devices utilizing earth thermal as a heat source face inefficiencies due to temperature differences between the heat transfer medium liquid and the earth thermal, leading to wasteful discharge of thermal energy and reduced heat exchange efficiency.
Innovation Solution
A method of controlling a heat exchange device that involves circulating a fixed amount of first heat transfer medium liquid in a circulation flow channel with a first heat exchange unit, and supplementing with a second heat transfer medium liquid from a heat source with a temperature difference, ensuring the detected temperature of the first heat transfer medium liquid maintains a required set temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a fixed amount of heat transfer medium liquid circulates in the heat exchange device, then the system operation is simple, but the heat exchange efficiency decreases when thermal energy is wasted
Solution Approach 1:
The patent implements a feedback control mechanism where a temperature detector continuously monitors the temperature of the heat transfer medium liquid, and a controller adjusts the supply amount of second heat transfer medium liquid based on the detected temperature to maintain the required set temperature, preventing thermal energy waste
Solution Approach 2:
The patent dynamically changes the supply amount parameter of the second heat transfer medium liquid based on temperature conditions, adjusting it to be supplied when the detected temperature is lower than the set temperature and stopping supply when the temperature requirement is met, thereby optimizing heat exchange efficiency
2Productivity
If the temperature difference between heat transfer medium liquid and earth thermal is large, then heat exchange efficiency is enhanced, but thermal energy is wasted due to unnecessary temperature difference
Solution Approach 1:
The patent makes the supply amount of second heat transfer medium liquid dynamic rather than fixed, adjusting it in real-time based on temperature detection to maintain an optimal temperature difference that enhances heat exchange efficiency while preventing thermal energy waste
Solution Approach 2:
The temperature detection and control mechanism provides continuous feedback to adjust the supply amount of second heat transfer medium liquid, ensuring the temperature difference between the heat transfer medium liquid and earth thermal is optimized for efficient heat exchange without excessive thermal energy loss

AI summary
A heat transfer medium liquid circulation flow channel having a first heat exchange unit exchanging heat to a second heat exchange unit is provided, and a fixed amount of first heat transfer medium liquid circulates therein. A feed pipe couples heat source holding second heat transfer medium liquid having temperature difference from the first medium liquid to the heat transfer medium liquid circulation flow channel. The feed pipe is coupled to an inlet end side of the first heat exchange unit and a discharge pipe is coupled to an outlet end side thereof. A necessary amount of second medium liquid is supplied to the inlet end side via the feed pipe so that a detected temperature of the first medium liquid in the outlet end maintains required set temperature. The same amount of the first medium liquid as the supplied second medium liquid is discharged out of the discharge pipe.
