摘要（英）：

The invention discloses a direct-expansion solar heat pump-based seawater desalination device. The direct-expansion solar heat pump-based seawater desalination device comprises a direct-expansion solar heat pump system, a raw material water tank, a heat-storage water tank, a flash tank and a main controller. The direct-expansion solar heat pump system comprises a solar heat-collection evaporator. An outlet of the solar heat-collection evaporator is orderly connected to a second triple valve, a gas-liquid separator, a compressor, a condenser, a liquid storage device, a drying filter, a liquid sight glass, a throttling device, a first triple valve and an inlet of the solar heat-collection evaporator by pipes. The first triple valve is orderly connected to a first solenoid valve, a heat regeneration evaporator, a condensation evaporator, a second solenoid valve and the second triple valve by pipes. The invention also discloses a seawater desalination method adopting the direct-expansion solar heat pump-based seawater desalination device. The direct-expansion solar heat pump-based seawater desalination device can fully utilize solar energy and ambient air heat, and improve energy utilization efficiency to the maximum degree by recovery of steam condensation latent heat, condensed fresh water sensible heat and discharged strong brine sensible heat.
