Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual testing of HVAC systems is time-consuming and inefficient, requiring significant time to perform hot and cold tests on multiple units, which can take several hours when done properly, and lacks automation for scheduling and highlighting issues across multiple sites.
Innovation Solution
The development of automated systems and methods for testing HVAC systems, allowing for simultaneous or individual testing of heating and cooling functionalities, including user-input driven setpoint changes and data storage, to streamline testing and identify errors, thereby reducing testing time and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual testing of HVAC systems is performed, then testing can be completed with basic equipment, but the testing process is time-consuming and inefficient
Solution Approach 1:
The HVAC system performs self-testing through automated control sequences that independently monitor heating and cooling functionalities, eliminating the need for manual intervention and significantly reducing testing time while maintaining comprehensive validation
Solution Approach 2:
The system pre-configures test sequences and setpoint adjustments before actual testing begins, allowing automated execution of standardized heating and cooling tests that can be rapidly deployed across multiple sites without manual setup
2Productivity
If automated testing is implemented, then testing time is reduced and efficiency is improved, but system complexity increases
Solution Approach 1:
The automated testing system uses a universal control interface that can test multiple HVAC units with different configurations through standardized procedures, reducing the need for site-specific customization while maintaining comprehensive testing capabilities across diverse equipment
Solution Approach 2:
The system automatically adjusts test parameters such as setpoints and timing based on the specific HVAC unit being tested, allowing a single automated testing framework to adapt to various equipment types and installations without requiring complex custom programming for each site
3Loss of time
If simultaneous testing of multiple HVAC systems is performed, then overall testing time is reduced, but error detection and analysis becomes more challenging
Solution Approach 1:
The automated testing system divides simultaneous tests into discrete, independently trackable sequences for each HVAC unit, with individual error logging and reporting that allows operators to identify and analyze issues in one unit without interference from other concurrent tests
Solution Approach 2:
The system implements real-time feedback mechanisms that monitor test results from multiple HVAC units simultaneously, automatically flagging errors and inconsistencies as they occur and providing immediate notifications to operators, thereby maintaining easy error detection even during parallel testing operations

AI summary
Systems, methods, and mediums perform automated functionality testing for a heating ventilation and air conditioning (HVAC) system. A method includes receiving a user input to test one of a heating or cooling functionality of the HVAC system. The method also includes identifying an amount to change a setpoint for a zone controller for the HVAC system based on the user input. The method further includes changing the setpoint for the zone controller to force the HVAC system into one of a heating mode and a cooling mode in accordance with the user input. Additionally, the method includes storing data from the HVAC system operating in the one of the heating mode and the cooling mode.
