The Radisson Blu Hotel Dubai Media City in the UAE has implemented a thermodynamic solar system for domestic hot water (DHW) production, according to a press release on Zawya.

This renewable energy option will fully substitute traditional electrical heaters in the hotel. The move aligns with Radisson Hotel Group’s aim to achieve net zero by 2050.

A thermodynamic solar system uses an air-source heat pump combined with solar blocks to produce hot water at 60°C.

The process involves compressing refrigerant fluid, causing it to boil in the solar blocks due to solar radiance and environmental temperature.

This transfers heat to the water in the heat exchanger.

The company further notes that on its first day of operation, the system reduced electrical consumption and carbon emissions of the hot water system by 65%.

Radisson Blu Dubai Media City and Park Inn Hotel Dubai Motor City cluster chief engineer Kathiravan Selvarasu said: “I am pleased to see the transformative impact of the thermodynamic solar system on hot water production in our hotel.

“The system can work without sun, in the shade, indoors or even during the night, producing hot water up to 60°C, 24 hours a day, unlike the traditional solar thermal systems that can only produce hot water with direct sunlight exposure.”

Radisson Blu Dubai Media City and Park Inn Hotel Dubai Motor City cluster general manager James Berry said: “The successful integration of the thermodynamic solar system is a clear step towards realising our sustainability goals.”

Radisson Blu Hotel, Dubai Media City is the fourth Radisson Blu hotel in the country to adopt this eco-friendly system.
