Solution Overview
Problem
Existing liquid applying apparatuses face high energy consumption due to inefficient control of exhaust and air conditioning systems, which are operated at constant rates regardless of the steam generation from the drying process, leading to excessive energy use.
Innovation Solution
A control system that includes a controller to manage an exhaust device and air conditioner based on the state of the liquid applying apparatus, adjusting exhaust and air supply amounts according to factors like operation state, steam generation, and environmental conditions to optimize energy use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the exhaust device and air conditioner are operated at constant rates, then the air environment inside the space is continuously maintained, but energy consumption increases due to excessive operation regardless of steam generation conditions
Solution Approach 1:
The exhaust device and air conditioner operate at variable rates based on real-time steam generation conditions detected by the controller. The system dynamically adjusts the operation level of these devices according to the liquid applying apparatus state, transitioning from constant-rate operation to condition-based variable-rate operation, thereby reducing energy consumption while maintaining adequate air environment control
Solution Approach 2:
The controller receives state information from the liquid applying apparatus and uses this feedback to adjust the operation of the exhaust device and air conditioner. This closed-loop control system monitors steam generation conditions and modulates the exhaust and air conditioning rates accordingly, ensuring energy-efficient operation while maintaining air environment quality
2Object-generated harmful factors
If the exhaust device operates at high rate, then steam is effectively removed from the space, but energy consumption increases and air environment stability deteriorates
Solution Approach 1:
The system changes the operational parameters of the exhaust device based on steam generation conditions. The controller adjusts the exhaust rate parameter dynamically, matching it to the actual steam production level from the liquid applying apparatus, thereby removing harmful steam effectively while avoiding energy waste from excessive exhaust operation
3Reliability
If the air conditioner operates continuously, then air environment is constantly adjusted, but energy consumption increases unnecessarily during low steam generation periods
Solution Approach 1:
The air conditioner operates periodically or at variable intervals based on steam generation conditions rather than continuous operation. The controller modulates the air conditioning operation according to the liquid applying apparatus state, enabling the system to maintain air environment quality during high steam generation while reducing or suspending operation during low steam generation periods, thereby significantly reducing air conditioning energy use
