According to the climatic features of the Yangtze River Basin and the area south of it develops a complex heat pump unit. Its condenser is composed of finned tubes and smooth tubes in series, characterising both air cooling and evaporative cooling modes. Presents configuration and operating principles of the unit, analyses its technical and economical characters and compares its energy efficiency with that of air cooled only heat pump units. Considers that the former possesses a greater market potential. A sample unit has operated through summer and winter seasons showing good energy saving.
