A　miniature　vapor　compression　refrigeration　equipment　prototype　was　developed　for　a　range　of　microclimate　control　applications,　including　man　portable　cooling　and　distributed　space　conditioning.　The　miniature　refrigeration　equipment　has　dimensions　of　260　mm　x　250　mm　x　120　mm,　and　weighs　approximately　2.85　kg.　The　optimal　motor　and　its　transmission　ratio,　the　optimal　dimension　of　capillary　tube　and　the　optimal　quantity　of　refrigerant　charge　were　obtained　by　matching　and　operating　performance　experimental　study.　Experimental　results　show　that　the　miniature　refrigeration　equipment　can　provide　300　W　cooling,　and　its　COPc　is　above　2.0.
