Solution Overview
Problem
Conventional air conditioners and warm air heaters struggle to maintain indoor temperatures accurately, often causing the temperature to deviate from set levels after operation stops, leading to inefficient heating and cooling.
Innovation Solution
A temperature management device that estimates the indoor set temperature by comparing the current temperature with the set temperature and adjusts the heat exchanger's operation, including varying the heat amount and wind volume for heaters, and refrigerant compression capacity and wind volume for air conditioners, to maintain the desired temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a general air conditioner maintains indoor temperature at set level, then cooling function is provided, but indoor temperature becomes lower than set temperature when operation stops
Solution Approach 1:
The controller estimates the indoor set temperature in advance and uses this estimated value to determine when to stop the cooling operation. By predicting the temperature trend and stopping before the actual temperature reaches the set point, the system prevents over-cooling and the subsequent temperature rebound that would require additional energy to correct.
Solution Approach 2:
The system continuously monitors the indoor temperature and uses this feedback to adjust the cooling operation. The controller compares the actual temperature with the estimated set temperature and dynamically controls the cooling capacity, ensuring the temperature is maintained within an acceptable range while avoiding excessive energy consumption.
2Reliability
If a general warm air heater supplies air at maximum heat amount and maximum wind speed, then heating function is provided, but indoor temperature rises continuously above set temperature when operation stops
Solution Approach 1:
The controller estimates the indoor set temperature and uses this information to determine the appropriate heating capacity and wind speed. By predicting when the temperature will reach the desired level, the system stops heating before the temperature exceeds the set point, preventing the continuous temperature rise and subsequent energy-wasting cooling period.
Solution Approach 2:
The system dynamically adjusts the heating capacity and wind speed based on the estimated set temperature and actual temperature conditions. Rather than operating at fixed maximum levels, the controller modulates these parameters to match the heating demand, ensuring efficient temperature maintenance without excessive energy consumption.
3Reliability
If air conditioner or warm air heater operates to maintain set temperature, then temperature control function is provided, but temperature deviation occurs above or below set level
Solution Approach 1:
The system performs self-service by automatically estimating the indoor set temperature using readily available data (indoor temperature, outdoor temperature, and temperature difference). This estimated value is then used to control the heating or cooling operation, eliminating the need for complex control algorithms while achieving improved temperature control precision.
Solution Approach 2:
The controller changes the operational parameters (cooling capacity, heating capacity, wind speed) based on the estimated set temperature and actual temperature conditions. By dynamically adjusting these parameters, the system achieves precise temperature control without requiring complex control systems, as the parameter changes are driven by straightforward temperature comparisons.
