Experimental and Numerical Study of the Radiant Induction-Unit and the Induction Radiant Air-Conditioning System

Abstract

Abstract:In this paper we proposed the novel air-conditioning system which combined induction ventilation and radiant air-conditioning. The indoor terminal device is the radiant induction-unit (RIDU). The RIDU is the induction unit combined with the pore radiant panel on which the copper pipes with rigid aluminum diffusion fins are installed. The two-stage evaporator chiller with the non-azeotropic mixture refrigerant is utilized in the system to reduce the initial investment in equipment. With the performance test and the steady state heat transfer model based on the theory of radiative heat transfer, the relationship between the induction ratio of the RIDU and the characteristic of the air supply was studied. Based on this, it is verified that the RIDU has a lower dew-point temperature and better anti-condensation performance than a traditional plate-type radiant panel. The characteristics of the radiation and convection heat transfer of the RIDU were studied. The total heat exchange of the RIDU can be 16.5% greater than that of the traditional plate-type radiant terminal.

Healthy Climate and Energy Savings: Using Thermal Ceramic Panels and Solar Thermal Panels in Mediterranean Housing Blocks

“…In addition, the extent of use of renewable energies in the TCP panel system was evaluated by incorporating thermal solar panels located on the common building roof into the system. To finish, we quantified the energy consumption of both systems for each component [37]: pumps, circulators, heat pumps, split ventilators, solar energy input from common roof panels, etc. Comparative tables were drawn up to show the energy saving results of TCP panel systems, especially when solar thermal panels were used in climatic areas with long periods of sunlight, both in summer and winter.…”
