City Multi Hybrid is match for city Hub hotel

UK: Mitsubishi Electric has provided Edinburgh’s Haymarket Hub hotel with a City Multi Hybrid VRF air conditioning system to deliver energy efficient, controllable comfort.

During a recent refurbishment of the hotel, All Seasons Group installed the two-piped air conditioning technology, which uses water to transfer heating and cooling around the 195-bedroom facility.

Eight dedicated outdoor condensing units deliver energy harvested from the outdoor air to special Hybrid Branch Controller (HBC) boxes strategically placed in laundry cupboards throughout the building.

From these control boxes, plastic water piping runs within the ceiling void to a dedicated indoor fan coil unit in every hotel room.

A centralised control system enables the hotel staff to monitor individual rooms, while allowing guests to have complete control of their own system. This delivers individual temperatures for each room, but ensures that empty rooms aren’t wasting energy and increasing bills for the hotel.

The design of the system also minimises any noise for guests, which is a major consideration in any hotel. The siting of the HBC boxes in the laundry room allows for easy access for maintenance and means individual rooms can be shut down without having to drain the whole system.
