HVAC Dynamic Temperature Control for Load Deficit Event Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
HVAC systems face load deficit events where the required load capacity exceeds the system's capacity, leading to inadequate temperature control, as they are configured to operate within default settings, limiting their ability to resolve such events effectively.
Innovation Solution
A temperature control device dynamically switches between standard and boost modes based on detected load deficits, using setting values outside default ranges for short durations to compensate for temperature differences, thereby improving resource utilization and performance.

Engineering Contradiction Analysis
1Reliability
If HVAC system operates within default setting ranges to ensure component reliability, then component reliability is improved, but load capacity is limited and ability to resolve load deficit events is reduced
Solution Approach 1:
The system dynamically adjusts operating settings based on detected load conditions. The controller monitors temperature differences and load deficit events, then switches between default settings and extended boost mode settings, making the system adaptable to varying demand conditions while maintaining reliability through controlled transitions.
Solution Approach 2:
The system changes operational parameters by switching between default setting values and extended boost mode setting values. When a load deficit event is detected, the controller modifies temperature setpoints and component operating parameters beyond their normal ranges to increase load capacity temporarily.
2Productivity
If HVAC system uses boost mode settings exceeding default ranges to compensate for load deficit, then load capacity is improved, but component wear increases
Solution Approach 1:
The system uses periodic or temporary boost mode activation rather than continuous operation. The controller detects load deficit events and activates extended settings only for the duration needed to resolve the temperature differential, then returns to default settings, creating a periodic on-demand operation pattern.
Solution Approach 2:
The system applies excessive action temporarily by using setting values that exceed default ranges only when necessary to resolve load deficit events. The boost mode operates beyond normal parameters just enough to compensate for the temperature difference, then returns to standard operation, applying partial excessive action rather than continuous over-operation.
3Reliability
If HVAC system operates in standard mode only, then component wear is minimized, but ability to achieve desired setpoint temperature during extreme weather is insufficient
Solution Approach 1:
The system dynamically switches between standard mode and boost mode based on detected load deficit events. The controller monitors temperature differentials and activates extended settings when the standard mode cannot achieve the desired setpoint temperature, creating a dynamic response to temperature control demands.
Solution Approach 2:
The system provides self-service by automatically detecting when standard mode is insufficient and activating boost mode without external intervention. The controller monitors system performance and temperature conditions, then autonomously transitions to extended settings to achieve the desired temperature, then returns to standard operation automatically.

AI summary
A device is configured to operate a Heating, Ventilation, and Air Conditioning (HVAC) system. The device is further configured to receive a temperature value and determine a load demand value based on the temperature value. The device is further configured to determine the load demand value is greater than the load capacity value for the HVAC system and, in response, identify a first setting from among a first plurality of settings for the HVAC system. By default, access to the first plurality of setting for the HVAC system is restricted for a user. The device is further configured to receive a response approving permission to operate the HVAC system using the first setting to the user and send a trigger signal to an HVAC controller to operate the one or more components of the HVAC system using the first setting.
