A system with functions of a heat pump and a hot gas defroster capable of improving efficiency is disclosed. The system with functions of a heat pump and a hot gas defroster comprises: a compressor; an indoor unit; an outdoor unit; a liquid/gas heat exchanger; an auxiliary heat exchanger; a liquid receiver, a liquid preheater, and a 4-way valve. The compressor compresses a refrigeration gas. The indoor unit condenses the refrigeration gas to perform heating or evaporates a refrigeration liquid to perform cooling. The outdoor unit condenses or evaporates the refrigeration gas. The liquid-gas heat exchanger exchanges heat between the refrigeration liquid and the refrigeration gas. |
