Abstract: A decentralized system for providing an optimized environment in a room, the decentralized system includes a balanced ventilation system and a fluid system both arranged in a housing. The decentralized system includes a compressor which is suspended by three or more springs attached to the compressor at a horizontal plane at the compressor's center of gravity or less than 20% of the compressor's length above or below the compressor's center of gravity.

Abstract: The present invention relates to a decentralized hybrid ventilation. The ventilation system comprises a housing having an inlet channel and an outlet channel. A first fan is arranged in the inlet channel for providing an airflow into the room and a second fan is arranged in the outlet channel for providing an airflow out of the room. A heat exchanger and filters are arranged in said channels for exchanging heat between and for filtrating air flowing into the room and air flowing out of the room. Furthermore, the ventilation system comprises a first and a second service door each providing, when open, an opening between the room and one of said channels to diverge the airflow from primarily flowing through the air filters and/or heat exchanger. The ventilation system also comprises a control system configured for switching between different modes of operations.

Abstract: An airtight enclosure comprising a pair of enclosure shells each having a pair of first edges and a pair of second edges extending transversely to the first direction. The first edges are spaced apart by a distance corresponding to the length of the second edges, the second edges are spaced apart by a distance corresponding to the length of the first edges, and the first edges have complementary assemblages for assembling first edges of the enclosure shells, and at least one of the second edges has a groove for accommodating a resilient sealing member in sealing contact with a second edge of the other one of the enclosure shells so that mating edges of each pair of second edge portions allow being assembled within a range of relative positions transverse to their longitudinal direction with the resilient seal or gasket in sealing contact with the mating edges.
