A　new　type　of　photovoltaic　(PV)/thermal　(PV/T)　air　evaporator　based　on　micro　heat　pipe　arrays　(MHPAs)　and　a　PV/T　air　dual　heat　source　direct-expansion　heat　pump　system　that　can　achieve　heating,　refrigeration,　and　PV　power　generation　were　developed.　System　performance　was　experimentally　investigated.　Results　showed　that　the　MHPAs　exerted　a　significant　cooling　effect　on　the　PV　modules,　which　were　cooled　by　31.6　degrees　C　under　the　experimental　conditions,　with　a　low　longitudinal　temperature　difference　of　2.1　degrees　C.　The　increase　in　PV　efficiency　was　5.3%.　The　evaporator　can　receive　heat　from　solar　energy　and　air　energy　under　appropriate　ambient　temperature,　and　the　average　heat　collection　efficiency　was　106.1%.　The　average　heating　coefficients　of　performance　(COP)　of　the　heat　pump　in　solar　(5),　combined　solar　and　air　(SA),　and　air　(A)　modes　were　2.8,　2.1,　and　2,　respectively,　under　typical　heating　conditions　during　winter.　Average　PV　efficiency　values　in　5　and　SA　modes　were　13.3%　and　6.8%,　respectively.　The　average　cooling　COP　was　2.2　and　the　average　PV　efficiency　was　11.2%　under　typical　cooling　conditions　during　summer.　The　performance　difference　and　control　strategy　in　various　modes　and　seasons　were　summarized.　This　research　provides　data　to　support　the　practical　application　of　heat　pump　systems.
