Run an app on a PC to configure and monitor the test.The compromises we jointly endorsed were: We made some suggestions that could satisfy their desires while also managing their time and cost budgets.įor example, by automatically populating the cells in an Excel template based on their original systems’ Excel spreadsheet, we provided streamlined report generation without having to rewrite all the calculation code embedded in their Excel file in another app. Viewpoint developed a monitoring and control durability test system that could exercise Zero Zone’s refrigerators through hundreds of operation cycles over multiple conditions to simulate actual usage in, for example, a grocery store.ĭuring initial conversations, we collaborated closely with Zero Zone to brainstorm on some potential approaches. Enable a way to find relevant data perhaps months or years after the test run.Simplify the manual configuration setup.Automate storage of measurements per a user-defined period to eliminate manual start/stop of data collection.Synchronize data collection and actuation.Minimize the chance of data loss during long test runs.Provide graphs and KPIs to enable faster analysis of the data during the test.Expand the measurements by adding more channels and channel types (e.g., 4-20 mA, ☑0 VDC and digital I/O).Zero Zone came to Viewpoint with the following high-level desires:

Furthermore, simplifying the data collection and analysis would make it easier to validate against ASHRAE standards. Plus, they had multiple models of their reach-in refrigerators that needed to be assessed.

Zero Zone was taking measurements with a datalogger with too few channels, and no synchronization, to other devices that feed into the system. You might think that refrigeration is a mundane product line, but that is just not true! So many innovations are occurring as manufacturers are redesigning their products to improve their environmental footprint through better energy efficiency, coolants, and durability.Īssessment requires an understanding of the performance of the refrigeration units under many conditions. Zero Zone wanted to improve the capabilities and durability of their new reach-in refrigeration products.
