Abstract: The invention relates to an arrangement for providing air to a room is provided. The arrangement comprises a first inlet for taking in air from the room, a first outlet for providing air to the room, a second inlet for taking in air from a space other than the room, the second inlet being connected to the first outlet and a second outlet for exhausting air to the space other than the room; the second outlet being connected to the first inlet. The arrangement further comprises a cooling duct connecting the first inlet and the first outlet, the cooling duct having a cooling module disposed therein for cooling air in the duct and a first flow control module for controlling a first airflow ratio between an exhaust airflow flowing from the first inlet to the second outlet and a cooling airflow from the first inlet to the first outlet.

Abstract: Methods for building a modular datacenter. At least two modular data center elements are built at a first location. The modular datacenter elements are transported separately from each other to a second location. A first modular datacenter element of the at least two modular datacenter elements is placed against a second modular datacenter element of the at least two modular datacenter elements, such that the front walls of the first and second modular datacenter elements are substantially parallel to one another and facing each other with the ledges, having substantially the same width, meeting each other to form a walkway.

Abstract: Modular datacenter element (100), comprising: a modular space defined by at least a bottom panel (120); and a front wall (110) having substantially the same length as the bottom panel, placed substantially vertically on the bottom panel; further comprising a plurality of racks for holding equipment, the racks being aligned in an opening in the front wall (110) along the length of the bottom panel (120); wherein a first side of the aligned plurality of racks is spaced away from a first edge along the length of the bottom panel at a distance substantially smaller than the width of the bottom panel, thus creating a ledge bottom part (126) between the first edge of the bottom panel and the plurality of racks. By creating a datacenter comprising multiple modular datacenter elements, a datacenter with efficient inspection possibilities and efficient air handling is created.
