HVAC Commissioning via Preconfigured Offline Configuration Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The commissioning of HVAC systems is often lengthy, error-prone, and challenging due to the need for manual data entry by technicians, especially in environments without internet connectivity, and lacks reliable pre-configured configuration files and installation manuals, leading to difficulties in ensuring accurate system validation.
Innovation Solution
A decentralized system comprising a computing device, central storage unit, and mobile device generates and transfers a pre-configured configuration file to the HVAC system, allowing for automated commissioning and validation, with the mobile device confirming the configuration and providing a customized installation manual, ensuring minimal human error and reliable operation even in non-internet connected environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual data entry is used for HVAC system commissioning, then the technician can configure the system on-site, but the process becomes lengthy and error-prone
Solution Approach 1:
The configuration file is prepared in advance at the manufacturing site with all necessary system parameters, building data, and component specifications. This preliminary configuration eliminates the need for lengthy on-site manual data entry, as the pre-configured file is simply transferred to the HVAC system during commissioning.
Solution Approach 2:
Instead of manually entering configuration data on-site, the invention uses a digital copy of the configuration file that is created at the manufacturing site and transferred electronically to the HVAC system. This copying approach replaces time-consuming manual entry with rapid digital transfer.
2Ease of operation
If manual data entry is used for HVAC system commissioning, then the technician can input configuration data, but errors increase due to manual entering
Solution Approach 1:
The configuration file is copied from the manufacturing site system to the on-site HVAC system without manual intervention. This digital copying process eliminates transcription errors and ensures configuration accuracy by maintaining data integrity throughout the transfer.
Solution Approach 2:
The HVAC system automatically receives and processes the configuration file through electronic transfer, eliminating the need for manual data entry by technicians. This self-service approach reduces human error while maintaining configuration capability.
3Adaptability or versatility
If the HVAC system is not connected to the internet, then system limitations are reduced, but access to configuration data becomes difficult
Solution Approach 1:
The configuration file serves as an intermediary that carries all necessary configuration data from the manufacturing site to the on-site HVAC system. This intermediary mechanism enables data transfer without requiring continuous internet connectivity, as the file is transferred offline and stored locally.
Solution Approach 2:
All configuration data is prepared and attached to the configuration file in advance at the manufacturing site, before the HVAC system is installed. This preliminary preparation ensures that complete configuration information is available offline, eliminating the need for internet access during on-site commissioning.
4Adaptability or versatility
If pre-configured files are not provided, then system flexibility is maintained, but commissioning efficiency decreases
Solution Approach 1:
The configuration file is created in advance at the manufacturing site with all system-specific parameters, building information, and component specifications. This preliminary configuration enables rapid on-site deployment while maintaining full system customization, as the file contains all necessary tailored settings.
Solution Approach 2:
The customized configuration file is copied from the manufacturing site to the on-site system, transferring the complete customized setup without manual reconfiguration. This copying process maintains system flexibility while dramatically improving commissioning efficiency.

AI summary
A method for configuring and commissioning an HVAC system, comprising generating, by a computing device, a configuration file for commissioning the HVAC system such that the HVAC system is brought into operation, wherein the configuration file is generated at a configuration site and the HVAC system is to be delivered to an operation site (S11); uploading, by the computing device, the generated configuration file to a central storage unit (S12); downloading, by a mobile device, the uploaded configuration file from the central storage unit (S13); transmitting, by the mobile device, the downloaded configuration file to an HVAC control unit comprised in the HVAC system located at the operation site (S14); and commissioning, by the HVAC control unit, the HVAC system located at the operation site with the transmitted configuration file (S15).
