Two areas of application: 1) bedrooms, 2) public areas & meeting rooms.

Mostmodern hotels have air conditioning fitted to client bedrooms. The client requirements for room temperature can vary enormously, especially if they have just arrived from overseas. Traffic noise and security issues mean that bedroom windows are kept shut, so air conditioning is essential to provide a comfortable environment for guests.

A small number of rooms can be air conditioned at low cost using SRK type wall split systems. These will have individual control, and can provide simple cooling and heating operations.

Larger hotels will require VRF systems, where one outdoor unit can be connected to 40 (max.) indoor units. So that a 200 bedroom hotel would have approximately 5 outdoor units. All of these can be individually controlled, and can be turned off if the room is unoccupied. VRF systems have variable speed compressors (the primary drive of the heating/cooling system) which allow energy saving at part load conditions. The variable speed is controlled by an INVERTER in the outdoor unit, dependent on the combined demand of the connected indoor units.

3D design staff can assist with the selection and layout of systems for hotel bedrooms, the routing of connecting pipework, drainage of condensate water from internal units, and control schemes to suit the client’s requirements.

PC Windows based control systems can be linked, in order to ensure energy is not wasted in unoccupied rooms, and set-back and group control can be changed easily. Key card switches can be integrated into the room unit control function, in order to save energy.

	FDQM Ducted – small concealed units mounted in ceiling bulkhead next to bathroom
	FDTQ Cassette – small cassette units also mounted in bulkhead
	FDK Wall mounted – high level wall mounted units
	FDFL Floor standing units – with cabinet
	FDFU Concealed floor standing units, built in to enclosure out of sight.

Full details of all of these units can be found in the Products section of this web site.

This is a regular source of revenue for hotels, and a growing requirement for developing businesses to have meetings away from their office premises.

We would never book a meeting room if it were not air conditioned. We have had bad experiences of noise disturbance from traffic, aeroplanes, lawnmowers, building contractors, etc. If we are shut up in a meeting room for 7 hours, air conditioning is essential.

Small rooms (< 8 people) can be air conditioned with a small wall mounted system, or ducted system, or floor mounted unit. Larger rooms would require FDTA Cassette or FDUMA Ducted systems, depending on their size, and the type of construction.

Bars, restaurants, reception area, fitness centre, lounge, all require heating, and are especially welcoming in a hot humid summer if they are fitted with air conditioning.

Heat pump systems are ideal for these locations; FDTA Cassette, and FDUMA Ducted systems are the most suitable for these open plan areas. Larger areas may require VRF systems, if there is a very mixed requirement for hating and cooling in different zones. 3D technical staff will be able to advise on this.
