Solution Overview

Problem

Conventional HVAC temperature control systems often fail to enhance user comfort and result in excessive energy consumption due to their reliance on a deviation relationship between indoor and set temperatures, neglecting the influence of outdoor conditions.

Innovation Solution

A temperature control method and system that adjusts the HVAC system's operation based on the difference between indoor and outdoor temperatures, using a target adjustment speed and energy-saving levels to determine optimal temperature adjustment levels and durations, thereby improving comfort and reducing energy usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If the HVAC system controls temperature based on deviation between indoor temperature and set temperature, then the temperature control function is achieved, but user comfort is insufficient and energy consumption is high

Engineering Contradiction:
Improveenergy consumptionVSAvoiduser comfort
Core Design Contradiction:
Loss of energyVSEase of operation

Solution Approach 1:

The system introduces outdoor temperature as an additional feedback parameter alongside indoor temperature. The controller dynamically adjusts the target temperature based on the temperature difference between indoor and outdoor environments, creating a multi-parameter feedback mechanism that optimizes both comfort and energy consumption.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system changes the control parameter from a fixed set temperature to a dynamic target temperature that varies based on outdoor conditions. By adjusting the target temperature parameter according to the temperature difference between indoor and outdoor environments, the system achieves adaptive control that reduces energy consumption while maintaining comfort.

Inventive Principle:
Principle #35Parameter changes

2Speed

If the HVAC system adjusts temperature quickly to reach set temperature, then response speed is improved, but energy consumption increases

Engineering Contradiction:
Improvetemperature adjustment speedVSAvoidenergy consumption
Core Design Contradiction:
SpeedVSUse of energy by moving object

Solution Approach 1:

The system implements dynamic temperature adjustment by continuously modifying the target temperature based on outdoor conditions and current indoor temperature. Rather than maintaining a fixed set point, the target temperature dynamically adapts to environmental changes, allowing the system to optimize adjustment speed and energy consumption in real-time.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system performs preliminary temperature adjustment by proactively modifying the target temperature before the temperature deviation becomes significant. By calculating the temperature difference between indoor and outdoor environments in advance, the system can prepare appropriate target temperatures that prevent excessive energy consumption while maintaining comfortable conditions.

Inventive Principle:
Principle #10Preliminary action

3Stability of the object's composition

If the HVAC system operates continuously to maintain set temperature, then temperature stability is achieved, but energy consumption increases

Engineering Contradiction:
Improvetemperature stabilityVSAvoidenergy consumption
Core Design Contradiction:
Stability of the object's compositionVSLoss of energy

Solution Approach 1:

The system implements periodic temperature adjustment by cycling between different target temperatures based on outdoor conditions and indoor temperature deviations. Rather than continuous operation at a fixed set point, the HVAC system periodically adjusts its target temperature, allowing for rest periods that reduce energy consumption while maintaining overall temperature stability.

Inventive Principle:
Principle #19Periodic action
