A 1-MW combined cooling, heat and power (CCHP) system is to provide cost savings and increased energy efficiency for a resort hotel in the US state of Hawaii.

The system will use a C1000 dual-mode propane high-humidity microturbine from microturbine energy systems manufacturer Capstone Turbine Corporation. The C1000 was made by Hawaiian design-build mechanical contractor Critchfield Pacific, which specialises in installing heating, ventilation and air conditioning systems with an emphasis on energy efficiency.

The CCHP configuration will allow the hotel to use exhaust heat from the microturbine to provide domestic hot water and pool heating via a heat exchanger, while also meeting the facility’s cooling needs through an absorption chiller.

In addition to boosting the site’s energy efficiency and reducing costs, the microturbine’s dual mode will enable the resort to function uninterrupted in the event of a power outage. Hawaii’s utility grid is expensive and can be unreliable, Capstone said.
