Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing HVAC monitoring and control systems lack remote automatic monitoring capabilities, leading to delayed detection and manual offline processes for malfunctioning units, which can cause additional stress on operational units and compromise temperature control.
Innovation Solution
A system and method for remotely monitoring HVAC units through a communication network, receiving and analyzing temperature, humidity, and CO2 data to generate control signals that can disable malfunctioning units, thereby preventing further stress and maintaining optimal temperature control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If remote automatic monitoring is implemented, then detection speed and response time improve, but system complexity and cost increase
Solution Approach 1:
The system continuously monitors HVAC parameters (temperature, humidity, runtime) and feeds this data back to a remote processor that automatically compares readings against thresholds and triggers alerts or control actions, eliminating manual monitoring while maintaining simple local hardware
Solution Approach 2:
A remote processor acts as an intermediary between simple local sensors and the HVAC system, performing the complex analysis and decision-making functions remotely while keeping local device complexity low
2Reliability
If manual monitoring processes are used, then system complexity remains low, but response time to malfunctions increases causing additional stress on operational units
Solution Approach 1:
The system establishes predetermined thresholds for HVAC parameters before operation begins, enabling automatic comparison and immediate detection of abnormal conditions without waiting for manual inspection or complex real-time analysis
3Measurement precision
If continuous monitoring of multiple parameters is performed, then malfunction detection accuracy improves, but energy consumption and processing requirements increase
Solution Approach 1:
Different monitoring functions are distributed: simple sensors locally capture temperature, humidity and runtime data, while complex analysis and threshold comparison are performed remotely, allowing high detection accuracy without requiring high processing power at the HVAC unit itself

AI summary
Systems, methods, and medium remotely monitor and control heating, ventilation and air-conditioning (HVAC) units. The method includes receiving by a processor via a communication network supply temperature data indicating a supply air temperature in a duct coupled to an HVAC unit. The method includes receiving by the processor via the communication network zone temperature data of a space being maintained by the HVAC unit. The method includes receiving by the processor via the communication network thermostat data from a thermostat in the space and analyzing by the processor at least one of the supply temperature data, the zone temperature data and thermostat data. The method includes generating by the processor a control signal responsive to the analysis and transmitting via the communication network the control signal to an HVAC controller, wherein the control signal causes the HVAC controller to control the HVAC unit.
