Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing HVAC systems lack centralized control for integrated temperature management, leading to inefficient energy usage as users often set temperatures excessively high in winter and low in summer, resulting in energy waste when left unattended.
Innovation Solution
A bandwidth temperature control apparatus using two relays and temperature control resistors, connected between the HVAC system and temperature sensors, allows for centralized control via a main controller and external communication IC, setting low and high temperatures to conserve energy by automatically adjusting based on set references.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If individual temperature control is used in HVAC systems, then each unit can be controlled independently, but centralized integrated control is lost leading to energy waste
Solution Approach 1:
The patent merges multiple independent temperature control units into a single centralized control system. The control unit integrates control signals for multiple HVAC devices (air conditioners, heaters, etc.) and coordinates their operation based on external temperature information, achieving energy-saving centralized control while maintaining individual device functionality.
Solution Approach 2:
The control unit receives external temperature information from external devices (smartphones, tablets, PCs) and uses this feedback to automatically adjust the operation of connected HVAC devices. This feedback mechanism enables the system to respond to user presence and environmental conditions, preventing energy waste when spaces are unoccupied or temperatures are already suitable.
2Adaptability or versatility
If complex control systems are implemented for centralized HVAC management, then integrated control capability is improved, but system complexity and cost increase
Solution Approach 1:
The control unit is designed with universal multi-functionality to manage diverse HVAC devices including air conditioners, heaters, and other temperature control equipment. It can process various types of control signals and communicate with multiple external devices through different communication protocols, providing integrated control capability without requiring separate specialized controllers for each device type.
Solution Approach 2:
The control unit acts as an intermediary device between external user devices and multiple HVAC devices. It receives control signals from external devices (smartphones, tablets, PCs) and translates them into appropriate control commands for the connected HVAC equipment, simplifying the overall system architecture by providing a single mediation point rather than direct complex connections between all devices.
3Ease of operation
If users set temperatures excessively high in winter and low in summer, then comfort is improved, but energy consumption increases
Solution Approach 1:
The system performs preliminary actions by pre-cooling or pre-heating spaces before users arrive, based on scheduled information received from external devices. This allows the HVAC system to be adjusted to energy-efficient temperatures during unoccupied periods while still providing comfortable conditions when users are present, reducing overall energy consumption without sacrificing comfort.
Solution Approach 2:
The control unit implements periodic temperature adjustments based on scheduled patterns and user presence detection. It automatically modifies temperature settings at different times (e.g., lowering AC temperature during daytime occupancy, raising it during nighttime or unoccupied periods), enabling flexible temperature control that adapts to usage patterns and minimizes energy waste during periods when extreme temperatures are not needed.
