I just wondered if anyone had any experience with aircon to a large hall.

I have been talking to a customer about installing 6 wall-mounted room units (10kW) to serve the hall which is 25x17x6m high. There is some existing vent ducting with gas heater, so this is just for the summer load.

With heating one would tend to go for a radiant heating system in this kind of scenario, and for cooling one might be thinking of a chilled beam (yes/no?). Has anyone had experience installing chilled beams in this kind of hall?
