An adsorption refrigeration device having an evaporator containing a refrigerant
liquid that evaporates under the effect of a depression and an adsorbent capable
of fixing the vapors (V) of the refrigerant liquid. The adsorbent is in contact
with a heat exchanger containing a cooling liquid that evaporates when the adsorbent
(205) is heated, and the heat exchanger includes at least one aperture to the outside
atmosphere constituted by at least one hole that limits the flow rate of the vapor
of the cooling liquid.
