Air conditioner and method for controlling air conditioner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users experience discomfort due to a mismatch between perceived and set temperatures in air conditioners, particularly when the wind volume mode affects the distribution of cooled air, leading to inconsistent sensory temperature experiences.
Innovation Solution
An air conditioner system that includes a processor to adjust the set temperature based on different correction values for various wind volume modes, ensuring the compressor turns off when the sensed temperature matches the corrected set temperature, thereby maintaining consistent cooling or heating across different wind modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the air conditioner stops discharging cooled air when the sensed temperature matches the set temperature, then energy consumption is reduced, but user comfort deteriorates due to temperature mismatch in low wind modes
Solution Approach 1:
The patent applies parameter changes by adjusting the set temperature based on the wind volume mode. Different correction values are added to the set temperature depending on whether the air conditioner is operating in strong wind, medium wind, or low wind mode. This dynamic parameter adjustment ensures that the compressor operates appropriately across different wind conditions, resolving the contradiction between energy savings and user comfort.
2Device complexity
If the air conditioner uses a single set temperature for all wind volume modes, then control simplicity is maintained, but temperature distribution uniformity deteriorates across different wind modes
Solution Approach 1:
The patent implements local quality by applying different correction values to the set temperature based on the specific wind volume mode. Instead of using a uniform control approach, the system tailors the temperature correction to each operating condition (strong wind, medium wind, low wind mode), ensuring optimal temperature distribution uniformity for each local operating scenario while maintaining relatively simple control logic.
3Use of energy by moving object
If the compressor turns off frequently in low wind mode, then energy efficiency is improved, but cooling effectiveness deteriorates due to insufficient air circulation
Solution Approach 1:
The patent applies preliminary anti-action by proactively adjusting the set temperature upward in low wind mode before the compressor would normally shut off. This preemptive temperature correction prevents the compressor from turning off too early, thereby maintaining cooling effectiveness and preventing temperature rise in areas with poor air circulation, while still allowing for energy-efficient operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system ensures user comfort by adjusting the set temperature according to wind volume modes, reducing the frequency of compressor shutdowns in low wind modes and prolonging cooling in strong wind modes, thus minimizing temperature discrepancies and user dissatisfaction.
Implementation Method 1
cool air by turning on the compressor
Implementation Method 2
discharge the cooled air to outside of the air conditioner by driving an indoor fan

AI summary
Disclosed are an air conditioner and a method for controlling the air conditioner. The air conditioner according to the present disclosure comprises: a fan; a compressor; a temperature sensor; and at least one processor, comprising processing circuitry, individually and/or collectively, configured to control the air conditioner to: turn on the compressor to cool air, discharge the cooled air to the outside of the air conditioner by driving an indoor fan based on an airflow mode among a plurality of airflow modes, correct a set temperature of the air conditioner based on a correction value corresponding to the airflow mode, and based on the temperature sensed by the temperature sensor matching the corrected set temperature, turn off the compressor in a state in which the driving of the indoor fan is maintained.
