IoT brings comfort to guests at Cultural Heritage Resorts

Cultural Heritage Resorts, a part of a reputed Sri Lankan hotel chain, recently partnered with Thermax to adopt an energy-efficient and sustainable approach for providing air conditioning. The resort is using Thermax’s double effect steam-driven vapour absorption chiller of 300 TR capacity, helping them save 4,92,000 units of electricity and reduce carbon emissions by 318 tons annually; equal to planting 31,885 trees or taking 63 cars off the road. The chiller utilises steam generated from biomass boiler to provide comfort cooling to hotel rooms through AHU/FCU units. Understanding the criticality of comfort in the hospitality industry, Thermax is also supporting the chiller with its IoT based service, ‘ROSS’ (Remote Online Support Service), which monitors and controls performance of absorption chillers across the globe. An abnormality was observed in the chiller installed at the Cultural Heritage Resorts due to operational issues. It was detected that vacuum was not within the required limit, resulting in the VAM outlet temperature not being maintained at the set point. Our smart service ‘ROSS’ proactively captured data, detected the root cause and avoided breakdown in air conditioning which would have caused discomfort to guests. Thermax’s experienced service engineer highlighted the issue to the customer and resolved it online by assisting the team to perform blowdown in the vacuum. This has resulted in significant cost savings to the hotel with no downtime.
