Concepts for a building integrated heating systems

Objectives: To development of new heating System optimised to be used in houses with low heating requirements. The new concept will be alternative to floor heating systems and demonstrate new methods based on low power miniature fan[otp3], which can accomplish the following interesting perspectives: 1) Use of the installed pipes as a control heat source for space heating. 2) Optimised operating condition in connection with light gas boilers. 3) Obtain high flexibility regarding building integration of the space heating system. 4) Obtain high design freedom of the heating system 5) Combined automatic demand control of heating system with integrated fresh air supply Program: The project has been divided into four phases, respectively: 1.) Heat distribution efficiency, which comprise the following task: - Heating system based on forced[otp4] convection. - Evaluation of control aspects and benefits. - Development of integrated demand controlled heating and fresh air systems. 2.) System efficiency, which comprise the following task: - Developments of strategies for automatic identification of the optimal combination of flow and supply temperature. - Establishment of simulation and full-scale experiment to verify the benefits of control strategies. - Evaluation of noise risk due to frequently thermal expansion of the pipe system. 3.) Demand control, whish comprise the following task: - Automatic recording of the heat load in individual rooms. - Methods for automatic estimation of the flow and supply temperature requirements. - On-line system benchmarking. 4.) Building integration, which comprise the following task: Proposals for integration of combined heating and fresh air system into the building construction. Proposals for integration in existing buildings. Status: Preliminary test regard heating systems base on forced convection from the pipe systems have been carried out by the company CONVEC Aps. The results up to now indicate that the heat performance form such arrangement is between 300 W to 600 W pr. meter. Expected results: Proposals and recommendations for high efficiency combined heating and fresh air concepts designed for integration into the building construction. It is the expectation that the project results can be utilized for development of new commercial heating concepts for houses
