S 1.27 Air conditioning

Initiation responsibility: Head of Site/Bldg Technical Service, Head of IT Section

Implementation responsibility: Site/Bldg Technical Service

In order to ensure the admissible range of the warmed up temperature of IT devices, the normal air exchange and heat transfer in a room sometimes does not suffice so that the installation of air conditioning is required. Its function is, through cooling, to keep the room temperature under the limit preset by the IT systems.

If, in addition, atmospheric humidity requirements exist, these can also be met by the air-conditioner through humidification and dehumidification. For this purpose, however, the air-conditioner will have to be connected to a water supply line. Account must be taken of S 1.24 Avoidance of Water Pipes.

In order to preserve the protective effect, provisions must be made for regular maintenance of the air-conditioning plant.

Additional controls:

• In which rooms used for IT purposes can increases in temperature occur?

• Are the air-conditioners in use being maintained on a regular basis?

• What are the maximum/minimum permissible temperature and humidity for the IT system?
