Procedure for housing at least one air conditioning unit, for example, a heating pump and/or a refrigeration device, in an acoustic housing, of which the acoustic housing is constructed of a lower part module and an upper part module, where the procedure consists of the following steps in chronological order: a) Providing a lower part module and an upper part module, where the lower part module and the upper part module assembled form the acoustic housing together, wherein the lower part module includes the following: - Housing walls, with a hollow body to incorporate at least one air condition unit and an insertion opening, through which insertion opening can at least one air conditioning unit be fit into the hollow body, and where the housing walls contain air intake openings for admitting air into the acoustic housing, and - a frame for the installation of at least one air conditioning unit and for the stability of the housing walls, whereas the housing walls are firmly connected with the frame, and where the frame is set up, the lower part module is in an upright condition on a foundation base, in which condition the insertion opening aligns with the foundation base at an oppositional angle to support; and where the upper part module includes the following: - Air outlet openings for releasing air from the acoustic housing, b) mounting of the lower part module onto a foundation base, in such a way as to position the insertion opening in the opposite direction to the foundation base; c) insertion of at least one air conditioning unit via the insertion opening into the hollow body of the lower part module in direction of an insertion direction, wherein the insertion direction is in essence orthogonal to the foundation base, d) placing at least one air conditioning unit onto the frame of the lower part module; e) attaching the upper part module to the lower part module, whereby the upper part module is positioned over the insertion opening and seals the insertion opening in such a way, that prevents the insertion of another air conditioning unit; f) affixing the upper part module with the lower part module to form the acoustic housing. a) Providing a lower part module and an upper part module, where the lower part module and the upper part module assembled form the acoustic housing together, wherein the lower part module includes the following: - Housing walls, with a hollow body to incorporate at least one air condition unit and an insertion opening, through which insertion opening can at least one air conditioning unit be fit into the hollow body, and where the housing walls contain air intake openings for admitting air into the acoustic housing, and - a frame for the installation of at least one air conditioning unit and for the stability of the housing walls, whereas the housing walls are firmly connected with the frame, and where the frame is set up, the lower part module is in an upright condition on a foundation base, in which condition the insertion opening aligns with the foundation base at an oppositional angle to support;
