Provided are a heat pump-based vaporization-condensation integrated machine and condensation method. The heat pump-based vaporization-condensation integrated machine comprises a first container (6), a third container (9), a fourth container (10), a separator (3), an air pump (4) and a heat pump system. As the heat pump-based vaporization-condensation integrated machine only needs to employ a heat exchange interface once to separate a condensed liquid, and utilizes the heat pump system to recycle a solvent, it requires no water consumption and features a simple structure, high processing efficiency and low power consumption. Performing separation twice at initial and final stages of condensation ensures that the condensed liquid is fully separated, and that the recycled solvent has a high purity. The use of mature heat pump technology ensures stability of a condensation facility. The heat pump-based vaporization-condensation integrated machine and condensation method can be widely applied in the technical fiel
