%X <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. The COP<sub>th</sub> can reach 0.46. </span><span style=\"font-family:Verdana;\">However, we can get a high performance if we
optimize temperature thresh</span><span style=\"font-family:Verdana;\">olds. </span><span style=\"font-family:Verdana;\">These
show that this type of cooling unit can help improve the habitat therm</span><span style=\"font-family:Verdana;\">al
comfort in a tropical and dry climate.</span></span></span></span>
