A temperature-control and fire-suppression system is provided for a system space, which optionally houses IT equipment. The system space has a ventilation system for providing controlled temperature air, for example to the IT equipment. A store of a fire-suppressing gas in liquid form is coupled to a supply means for supplying the fire-suppressing gas in liquid form to the system space, such that evaporation of the fire-suppressing gas in liquid form cools, or absorbs energy, from, the air in the system space. A temperature sensor is provided for sensing a temperature in the system space and a controller is responsive to the sensed temperature for controlling the supply means, to supply the fire-suppressing gas in liquid form while maintaining the sensed temperature above a predetermined lower temperature. |
