چکیده
A membrane-based enthalpy exchanger is a device used for heat and humidity recovery in ventilated buildings. The energy-saving potential of such dependent on the parameters responsible moisture recovery. trend toward composite membranes, which are custom produced, their can be adjusted given application; therefore, diffusion sorption characteristics membranes unknown. In order to obtain values water vapor diffusivity three investigated handmade serial resistance model using Field Laboratory Emission Cell (FLEC) proposed. Experiments were conducted identify each step transfer process extract membranes. calculated diffusivities 8.99 × 10?12 (m2/s) from cellulose acetate, 1.9 10?10 microporous PE/PUR 1.53 10?11 PET/PUR microfibrous obtained membrane then proposed effectiveness-NTU-based an with cross-flow arrangement predict performance under various operating conditions. results show that highest latent effectiveness was found core made lowest one core.

New Polymer Catalytic Membranes for Nitrite Reduction: Experimental Assessment
In this work we report the experimental assessment of the performance of a new catalytic hollow fiber reactor with supported Pd catalyst for nitrite removal from polluted waters. The reactor configuration facilitates working at low flowrate and hydrogen concentrations in order to improve the selectivity of the reduction reaction towards nitrogen, thus, inhibiting the formation of ammonia. Pd ca...
متن کاملDown-Hole Heat Exchangers: Modelling of a Low-Enthalpy Geothermal System for District Heating
In order to face the growing energy demands, renewable energy sources can provide an alternative to fossil fuels. Thus, low-enthalpy geothermal plants may play a fundamental role in those areas— such as the Province of Viterbo—where shallow groundwater basins occur and conventional geothermal plants cannot be developed. Thismay lead to being fuelled by locally available sources. The aim of the ...
