摘要：

Vapor　compression　heat　pump　has　a　good　prospect　of　application　in　high　temperature　environments　and　high-power　spacecraft　thermal　control　system.　Aerospace　vapor　compression　heat　pump　operates　in　the　microgravity　environment.　Microgravity　vapor　compression　heat　pump　adaptability　is　the　key　to　a　vapor　compression　heat　pump　technology　aerospace　research　and　development.　The　evaporator　is　a　key　component　of　the　vapor　compression　heat　pump.　By　calculating　vapor　compression　heat　pump　evaporator　to　explore　its　gravity-independent　conditions　and　get　gravity-independent　critical　velocity　and　critical　diameter　at　different　evaporation　temperatures　and　under　different　flow　rates.　The　results　showed　that　the　minimum　critical　velocity　in　the　evaporator　gravity-independent　region　in　1.45-1.5　m·s-1.　The　maximum　critical　diameter　increases　with　cooling　capacity,　and　cooling　capacity　from　50　W　to　300　W,　the　critical　diameter　from　0.42　mm　to　1.02　mm.　©　All　Rights　Reserved.
