Abstract
The high energy consumption of air conditioning has led to the development of alternative cooling systems. The air conditioning by adsorption bed containing an adsorptive effect capable of producing a refrigerator through evaporative cooling is one alternative to replace the air conditioning vapor compression in specific applications. The possibility to use solar energy to supply the energy needed for regeneration of adsorbents makes this alternative is very feasible in tropical countries such as Brazil. However, the hot water cycle should be well sized to avoid unnecessary energy waste and mixtures in the heat storage tank. Thus, it is important to evaluate the return of hot water from the storage tank adsorbents. This paper aims to present the development of a computer program called SimAds, able to simulate the flow of water within an adsorptive bed and indicate the time required for regeneration of the same and the profile of the hot water that leaves the bed to return the thermal storage tank. The SimAds generated the hot water temperature data to study the air conditioning central heat storage adsorptive SLE - UFPB, still in the installation phase. The software results were compared with experimental results in flow bed adsorptive raised by SAHA et al. and showed average errors of 1.37 K at exit temperature, and 12.4% in the time for heating the bed.
