Most modern 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 16 (max.) indoor units. So that a 200 bedroom hotel would have approximately 14 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. The inverter and associated components are subject to Enhanced Capital Allowance, against company corporation tax.

Our 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.
