Solution Overview
Problem
The existing systems for managing temperature in rooms with charge discharge devices struggle to efficiently regulate temperature, leading to excessive heat generation that can overload or malfunction air conditioners and reduce their performance.
Innovation Solution
A temperature management system that includes charge discharge devices with external air conditioning modules and a managing server, which adjusts room temperature by operating external air conditioning modules based on peripheral temperature and cooling idle capacity, minimizing the load on air conditioners and allowing for more efficient cooling by strategically operating multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a single air conditioner is used to cool the room with charge discharge devices, then the installation space is reduced, but the cooling capacity is insufficient when heat generation is high
Solution Approach 1:
The system divides the cooling function into multiple independent charge discharge devices, each equipped with its own air conditioning module. Instead of relying on a single centralized air conditioner, the cooling capacity is segmented across multiple devices that can operate independently or cooperatively based on thermal conditions and idle capacity availability.
2Temperature
If multiple air conditioning modules are operated simultaneously, then the cooling capacity is sufficient, but the energy consumption increases
Solution Approach 1:
The managing server continuously monitors the thermal conditions of each charge discharge device and the idle capacity of air conditioning modules. Based on this feedback information, the server dynamically determines which modules to operate and when, optimizing energy consumption by activating only the necessary cooling capacity required at any given moment.
Solution Approach 2:
The system operates air conditioning modules partially or selectively based on actual cooling needs. Instead of running all modules at full capacity continuously, the managing server activates only the portion of cooling capacity that is currently needed, allowing for energy-efficient operation while maintaining adequate temperature control.
3Temperature
If the air conditioner operates at high capacity, then the cooling effect is strong, but the air conditioner may overload or malfunction
Solution Approach 1:
By segmenting the cooling load across multiple charge discharge devices with individual air conditioning modules, no single device needs to operate at excessive capacity. This distribution prevents any one air conditioner from being overloaded, thereby maintaining reliability while achieving the required overall cooling effect.
4Power
If external air conditioning modules are added to charge discharge devices, then the cooling capacity is improved, but the device complexity increases
Solution Approach 1:
The air conditioning modules integrated into charge discharge devices serve dual purposes: they cool the battery chambers during charging/discharging operations and also contribute to overall room temperature control. This multi-functionality justifies the added complexity by providing versatile cooling capabilities without requiring entirely separate systems.

AI summary
A temperature management system for a room with a charge discharge device installed is provided, and the temperature management system includes one or more charge discharge devices installed in a room, performing charging or discharging of a battery, and including an external air conditioning module adjusting air temperature in the room, and a managing server controlling operation of the external air conditioning module of each of the charge discharge devices to adjust temperature in the room. When the temperature of the room with a charge discharge device installed increases due to heat generated by charging or discharging of the battery, the charge discharge devices may cool the air of the room, and a load to an air conditioner installed in a building can be reduced.
