Abstract: The invention relates to a cuboidal housing for components of a HVAC system. The housing has at least one air inlet, at least one air outlet and a frame. The frame consists of twelve segments which form edge lines. The segments span six open side surfaces in a sealing manner with the open side surface of an adjacent housing, and an insulating means is located between the inner wall and the outer wall. Each panel element has a plastic profile wherein the profile has two bearing limbs each having a bearing surface. In the fitted state, the bearing surface of one bearing limb is in contact with the outer side of the frame segment directly or via at least one further component. In the fitted state, the bearing surface of the other bearing limb faces that side of the frame segment which is facing in the direction of the interior.

Abstract: A room ventilating and air conditioning system has at least one flow duct for a medium flowing therein and at least two air-related components. One component has a receiver and one component has a transmitter and the two components are connected via a wire-free connection, in particular a radio connection. At least one of the transmitters should project, at least with a subregion, to such an extent into the interior of the flow duct that the waves emitted by this transmitter are conducted substantially through the flow duct and/or at least one of the receivers should project, at least with a subregion, to such an extent into the interior of the flow duct that it is able to receive the waves conducted substantially through the flow duct.
