▎ 摘  要

NOVELTY - The machine comprises an evaporator (4). An evaporator fin surface is coated with the graphene dispersion liquid to form a layer of graphene film having strong hydrophobicity for delaying the frosting time of the evaporator fin surface, and reducing frosting quantity to inhibit the effect of frosting. USE - Defrosting type heat pump outdoor machine. ADVANTAGE - Since graphene has strong hydrophobicity, the heat pump is in heating operation, the evaporator fin condensation is not easy to spread on the surface, the thermal conduction velocity can be effectively reduced and the frosting time can be greatly prolonged. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for preparing graphene dispersion liquid; and (2) a coating machine for defrosting type heat pump outdoor machine. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the defrosting type heat pump outdoor machine. Compressor (1) Condenser (2) Capillary tube (3) Evaporator (4) Spray gun (5)
