Condensing device and heat pump system comprising same

Abstract

This application discloses a condensing device and a heat pump system including the same. The condensing device includes: a shell; and at least two sets of heat exchange tube bundles, where each set of heat exchange tube bundles includes a condensing tube bundle and a subcooling tube bundle, and the subcooling tube bundle is arranged below the corresponding condensing tube bundle, where the at least two sets of heat exchange tube bundles are configured to circulate the cooling medium independently, to enable the cooling medium in each set of heat exchange tube bundles to perform heat exchange with the refrigerant in the heat exchange accommodating cavity independently. Two subcoolers are arranged in a same shell of the condensing device of this application, where one subcooler may be used in an independent refrigeration mode, and the other subcooler may be used in a water heating mode. In the independent refrigeration mode, the subcooler can improve the refrigeration performance of the heat pump system. In the water heating mode, in addition to improving the performance of the heat pump system, the subcooler can further reduce the size of an economizer in the heat pump system, and finally reduce the occupied area of the unit.
