摘要
<span style="font-family:Verdana;">This work concerns a modeling of habitat equipped with an adsorption cooling unit powered by a geothermal heat pump in the context of the climate of the Comoros Islands. Cooling unit is a simple system consisting of an a</span><span style="font-family:Verdana;"><span style="font-family:Verdana;"><span style="font-family:Verdana;">d</span></span></span><span><span><span style="font-family:;" "=""><span style="font-family:Verdana;">sorber, </span><span style="font-family:Verdana;">condenser and evaporator. The modeling of the habitat-air conditioning system was based on a description of heat and mass transfers. The first</span><sup> </sup><span style="font-family:Verdana;">law of thermodynamics on the energy conservation using the analogies between heat and electrical transfers is used to establish the equations of the model. Zeolite-methanol pair and Dubinin-Astakhov adsorption model are used to describe the amount of adsorbed mass. The finite difference method applied to a point of the considered exchange surface is used to discretize equations and </span><span style="font-family:Verdana;">resolve them. The coupling of the system takes place through a convective tr</span><span style="font-family:Verdana;">ansfer betw</span><span style="font-family:Verdana;">een the air inside habitat and the evaporator</span><span style="font-family:Verdana;">’s surface. This article </span><span style="font-family:Verdana;">presents results for typical November days in Comoros. Different temperatu</span><span style="font-family:Verdana;">res </span><span style="font-family:Verdana;">of habitat with and without a cooling unit show that using the adsorption co</span><span style="font-family:Verdana;">oling unit can help lower internal temperatures. We observe a temperature difference of 2.14 K in particular at 2 p.m., if the air conditioning starts at 8 a.m. The influence of the input parameters on the air inside the habitat makes it possible to assess the impact on indoor comfort.
