Central Chiller Plant Control for a Five-Star Hotel

IndustryResort Hotel
LocationSanya, China
Scale5-star / 380 rooms
Year2025

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

DANRENS Wi-Fi thermostats were installed in 380 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.
