Central Chiller Plant Control for a Five-Star Hotel

Case Study

Central Chiller Plant Control for a Five-Star Hotel

Project Background

A beachfront resort in Sanya received frequent guest complaints about rooms that were too warm at check-in and too cold overnight.

Our Solution

DNARENS Wi-Fi thermostats were installed in 360 guest rooms with occupancy-based setback. The plant side used a chilled-water reset strategy driven by our controller.

Results

Guest comfort scores rose noticeably while plant energy stayed flat despite higher occupancy, thanks to demand-based room control.
