Innovation Solution

A temperature controller and server system that adjusts set temperatures based on a green electricity index, optimizing energy usage by increasing or decreasing temperatures in response to changes in green electricity availability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If the set temperature is adjusted according to green electricity index to improve green electricity utilization, then carbon emissions are reduced, but temperature control stability deteriorates

Engineering Contradiction:
Improvecarbon emissionsVSAvoidtemperature control stability
Core Design Contradiction:
Loss of energyVSStability of the object's composition

Solution Approach 1:

The system performs preliminary actions by pre-cooling or pre-heating spaces when green electricity availability is high, storing thermal energy in the building structure (walls, floors, furniture). This allows the system to maintain comfortable temperatures during periods when thermal electricity is used, reducing carbon emissions while maintaining temperature stability through the thermal mass of the building components.

Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system implements a feedback mechanism where the temperature controller continuously monitors the green electricity index from the power grid and automatically adjusts the set temperature accordingly. When green electricity availability increases, the system adjusts temperatures to increase consumption; when it decreases, the system reduces consumption. This automated feedback loop improves green electricity utilization efficiency without requiring complex user intervention.

AI summary

The present application provides a temperature controller, a server, an air conditioning system and a temperature setting method. The temperature controller may be configured to operate in a carbon saving mode, and when operating in the carbon saving mode, the set temperature of the temperature controller is adjusted according to a green electricity index, and the green electricity index is the proportion of green electricity in a power grid to which the temperature controller is connected. When the proportion of the green electricity is high, i.e., the electric energy used is mainly from renewable energy sources, the set temperature is adjusted to produce more cold energy or heat energy for storage; and when the green electricity index decreases, the stored cold energy or heat energy can be used to meet the demand for cooling or heating, which ensures the comfort of a user and at the same time, decreases energy consumption, thereby reducing carbon emissions.
