| Abstract [eng] |
The work deals with simple heat recovery system which is reliable in providing warm & fresh air to the small room with low cost and low maintenance. The purpose of this work is to design a compact waste heat recovery unit for small premises and investigate the airflow characteristics. A design of the unit is proposed and a prototype is manufactured, which was tested in both numerical simulation & experiments using a pressure chamber to obtain airflow- static pressure curves. The unit was designed using SolidWorks computer aided design software and the simulation was carried out using SolidWorks Flow Simulation computational fluid dynamics software. The experiments & simulation were carried out with a use of different fans to see the difference in airflow, static pressure. The numerical simulation results show a good agreement with the results of experimental investigation. Also, the numerical simulation shows that depending on the fan or its speed, the heat recovery efficiency of the device can be achieved up to 55 %. The research indicates that the device is suitable for use in a small residential building up to 45 m2. |
