<p>The present invention relates to a coolant circulation system of a heat pump and, more specifically, to a coolant circulation system of a heat pump which produces water at a preferred temperature without generating frost on a evaporator of the heat pump. The present invention comprises a first heat exchanger; a second heat exchanger; solenoid valves; expansion valves; a sensor for the temperature of discharged gas; a sensor for the temperature of compressed gas; and a controller. The first heat exchanger exchanges the heat of coolant gas, which was generated in a compressor by high temperature and high pressure and transferred through a pipeline, with water being circulated through a pipeline by a circulation pump, and provides the hot water which has completed the heat transfer to a hot water tank.</p> |
