Solution Overview
Problem
Existing central air conditioners face challenges in accurately determining the pre-cooling or pre-heating time, leading to energy wastage and discomfort due to variations in cooling consumption and weather conditions.
Innovation Solution
An air conditioner control method and apparatus that determines whether the time interval to the start of work is within a maximum early start duration, and based on the preparatory demand load and startup combination load, calculates the optimal start moment for the air conditioner to ensure accurate pre-cooling or pre-heating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the air conditioner starts early to ensure comfortable indoor environment, then the indoor temperature requirement is met, but energy consumption increases
Solution Approach 1:
The system dynamically adjusts the preparatory period based on real-time factors including outdoor temperature, indoor heat source conditions, and cooling consumption data from previous days. Instead of using a fixed half-hour or one-hour preparatory period, the control method calculates the optimal start time by evaluating current weather conditions and thermal load characteristics, enabling the air conditioner to adapt its operation schedule to actual environmental conditions and minimize energy consumption while ensuring comfort requirements are met.
2Ease of operation
If the air conditioner uses a fixed preparatory period of half an hour or one hour, then the system operation is simple, but the energy consumption increases due to unnecessary early operation
Solution Approach 1:
The control method implements a feedback mechanism that collects and analyzes cooling consumption data from previous days, outdoor temperature variations, and indoor heat source conditions. This feedback information is used to continuously optimize the preparatory period calculation, allowing the system to learn from historical performance and adjust future operation schedules accordingly. The feedback loop enables the system to identify patterns in thermal load and weather conditions, progressively improving energy efficiency while maintaining simple operation through automated decision-making.
3Loss of energy
If the air conditioner reduces the preparatory period to save energy, then energy consumption decreases, but the indoor temperature requirement is not met
Solution Approach 1:
The system performs preliminary calculations of the optimal preparatory period by evaluating outdoor temperature forecasts, indoor heat source schedules, and historical cooling consumption patterns before determining the actual start time. This preliminary assessment allows the system to identify the minimum necessary operation duration required to achieve the desired indoor temperature, avoiding both excessive early operation and insufficient preparation time. The preliminary action phase computes the precise thermal load requirements and determines the optimal window for air conditioner operation.
4Stability of the object's composition
If the air conditioner operation time is extended to maintain indoor temperature, then the temperature stability is improved, but the energy consumption increases
Solution Approach 1:
The control method dynamically changes key operational parameters including the preparatory period duration, operation timing, and load adjustment based on real-time environmental conditions. By varying these parameters according to outdoor temperature, indoor heat source activity, and historical performance data, the system optimizes the balance between temperature stability and energy consumption. The parameter changes enable the air conditioner to operate at optimal efficiency points while maintaining indoor comfort, avoiding continuous operation at fixed settings that would waste energy.
