Solution Overview

Problem

Conventional cooling systems do not optimize power consumption across all components, leading to inefficiencies in refrigerant cooling and overall system energy usage.

Innovation Solution

A cooling system with a first cooling apparatus and multiple second cooling apparatuses, where a setting section dynamically adjusts the first set temperature based on individual second set temperatures of the second cooling apparatuses, enabling variable power management through heat exchange and free cooling mechanisms to minimize total power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If the first set temperature is lowered, then thermal energy is more readily available for heat exchange in second cooling apparatuses, but the efficiency of the first cooling apparatus decreases

Engineering Contradiction:

Improvethermal energy availability for heat exchangeVSAvoidpower consumption of first cooling apparatus

Core Design Contradiction:

Loss of energyVSUse of energy by moving object

Solution Approach 1:

The patent applies parameter change by adjusting the first set temperature based on the thermal energy requirements of the second cooling apparatuses. Rather than maintaining a constantly low first set temperature, the system dynamically modifies this parameter to match the actual thermal energy needs, thereby improving the efficiency of the first cooling apparatus while still providing sufficient thermal energy for heat exchange operations.

AI summary

A cooling system includes: a first cooling apparatus electrically driven to supply a first heat transfer medium cooled to a first set temperature or lower; a plurality of second cooling apparatuses each of which includes a heat exchanger that exchanges heat between the first heat transfer medium supplied from the first cooling apparatus and a second heat transfer medium, and is electrically driven to supply a third heat transfer medium cooled to a second set temperature or lower, the second set temperature being changed individually with lapse of time; and a processor that obtains second set temperatures of the second cooling apparatuses and sets the first set temperature based on the obtained second set temperatures.
