A　novel　parallel　flow　aluminum　flat　tube　adsorption　bed　structure　was　designed　and　an　adsorption　type　refrigeration　experimental　bench　was　set　up.　The　performance　difference　of　the　adsorption　refrigeration　system　under　different　external　operation　strategies　was　experimentally　studied,　and　the　changes　of　the　COP　of　the　adsorption　refrigeration　system　under　different　heat　source　and　cold　source　temperature　and　heat　exchange　fluid　flow　were　compared.　The　results　show　that　when　the　cold　source　temperature　is　10,　the　heat　source　temperature　is　60　and　the　flow　rate　is　0.26　kg/s,　the　COP　of　the　new　adsorption　refrigeration　system　reaches　the　maximum　value　of　0.35　under　the　experimental　conditions.　When　the　cold　source　temperature　is　near　20,　increasing　the　heat　source　temperature　can　effectively　improve　the　COP　of　the　adsorption　refrigeration　system,　and　the　larger　the　heat　exchange　fluid　flow,　the　more　significant　the　increase;　when　the　heat　exchange　fluid　flow　is　0.13∼0.26　kg/s,　the　system　COP　decreases　sharply　with　the　increase　of　the　temperature　of　the　cold　source,　and　the　smaller　the　flow　rate　of　the　heat　exchange　fluid,　the　more　significant　the　downward　trend.　When　the　heat　source　temperature　is　55∼60,　the　COP　changes　with　heat　transfer.　The　increase　of　the　fluid　temperature　significantly　increases,　and　the　higher　the　temperature　of　the　cold　source,　the　more　obvious　the　tendency　of　COP　increase.　©　2020,　Science　Press.　All　right　reserved.
