Abstract:
1. A method for assembling heat exchanger elements including a fibrous mat, wherein the fibrous mat has a thickness of at least 25 mm and includes fibers which are interconnected by a bonding agent, and at least one heat exchanging conduit for a heat exchanging medium, the heat exchanger elements being panel shaped and including at least two main surfaces averted from each other and a peripheral surface connecting the main surfaces, the method comprising: attaching at least two heat exchanger elements adjacent to each other, to a room delimiting surface, wherein uncoated main surfaces of the fibrous mats are glued to said room delimiting surface, and in a first step, a first row of heat exchanger elements are fastened with their first lateral surfaces situated side by side, in a second step, holding elements are mounted to join the second side surfaces, in a third step, a second row of heat exchanger elements are fastened so as to join said holding elements and their first side surfaces engaging each other, in a fourth step, the two branch necks of each heat exchanger element are connected to a heat exchanger circuit, in a fifth step, a cast mixture is applied over the heat exchanger elements and the at least two branch necks so that a substantially flat cast surface is obtained, wherein a thickness of the cast mixture is in a range of 2 to 8 mm and the at least one heat exchanging conduit is contained in the cast mixture, and wherein the cast mixture together with the at least one heat exchanging conduit, adheres to the fibrous mat.
