An　MIL-101(Cr)　powder　material　was　successfully　prepared　using　the　hydrothermal　synthesis　method,　and　then　the　original　MIL-101(Cr)　was　combined　with　different　mass　fractions　of　CaCl(2)using　the　immersion　method　to　obtain　a　MIL-101(Cr)/CaCl(2)composite　material.　The　physical　properties　of　the　adsorbent　were　determined　by　X-ray　powder　diffraction　(XRD),　an　N2　adsorption　desorption　isotherm　test,　and　thermogravimetric　analysis　(TG).　The　water　vapor　adsorption　performance　of　the　metal-organic　frameworks　MOFs　was　tested　with　a　gravimetric　water　vapor　adsorption　instrument　to　analyze　its　water　vapor　adsorption　mechanism.　Based　on　the　SIMULINK　platform　in　the　MATLAB　software,　a　simulation　model　of　the　coefficient　of　performance　(COP)　and　cooling　capacity　of　the　adsorption　refrigeration　system　was　established,　and　the　variation　trends　of　the　COP　and　cooling　capacity　of　the　adsorption　refrigeration　system　under　different　evaporation/condensation/adsorption/desorption　temperatures　was　theoretically　studied.　MIL101-(Cr)/CaCl2-20%　was　selected　as　the　adsorption　material　in　the　adsorption　refrigeration　system　through　the　physical　characterization　of　composite　materials　with　different　CaCl(2)concentrations　by　means　of　adsorption　water　vapor　test　experiments.　A　closed　adsorption　system　performance　test　device　was　built　based　on　the　liquid　level　method.　The　cooling　power　per　unit　and　adsorbent　mass　(COP　and　SCP)　of　the　system　were　tested　at　different　evaporation　temperatures　(288　K/293　K/298　K);　the　adsorption　temperature　was　298　K,　the　condensation　temperature　was　308　K,　and　the　desorption　temperature　was　353　K.　The　experimental　results　showed　that　COP　and　SCP　increased　with　the　increase　in　the　evaporation　temperature.　When　the　evaporation　temperature　was　298　K,　the　level　of　COP　was　0.172,　and　the　level　of　SCP　was　136.9　W/kg.　The　COP　and　SCP　of　the　system　were　tested　at　different　adsorption　temperatures　(293　K/298　K/303　K);　the　evaporation　temperature　was　288　K,　the　condensation　temperature　was　308　K,　and　the　desorption　temperature　was　353　K.　The　experimental　results　showed　that　the　levels　of　COP　and　SCP　decreased　with　the　increase　in　the　adsorption　temperature.　When　the　adsorption　temperature　was　293　K,　the　level　of　COP　was　0.18,　and　the　level　of　SCP　was　142.4　W/kg.
