Aiming at the deficiency of the existing defrosting method for air-source heat pumps, proposes a new solution defrosting method, and regenerates the dilute solution by frozen method. Explains the principle of solution defrosting and frozen regeneration, designs a solution defrosting and frozen regeneration system for air-source heat pump. Presents its operation process (cooling, heating defrosting, frozen regeneration and ice removing). Determines the defrosting solution type and applicable concentration range, and analyses the system performance.
