By　using　micro　electromechanical　system　(MEMS)　technology,　a　miniature　vapor　compression　heat　pump　prototype　is　developed　based　on　the　optimized　design　of　micro　Wankel　compressor　without　air　outlet　valve.　The　matching　of　compressor　and　power　system　is　considered,　further　more,　the　matching　of　micro　condenser,　micro　evaporator　and　capillary　length　has　been　studied　experimentally.　The　heat　pump　weighs　approximately　4　kg,　have　dimensions　of　260　mm　×　250　mm　×　120　mm,　can　provide　300　W　cooling,　and　the　CCOP　is　above　2.0.　The　system　can　run　for　90　min　driven　by　high　performance　lithium　battery.
