<p>The purpose of the present invention is to provide a binary heat pump system using an air heat source, which has a case housing a heat exchanger, a low-temperature cycle evaporator, and an air blower therein and having an air inlet and an air outlet, wherein the heat exchanger is capable of transferring a refrigerant heat at a high-temperature side in a high-temperature cycle therethrough, thereby improving efficiency and stably performing an cooling and a heating operation. According to the present invention to achieve the above purpose, provided is a binary heat pump system using an air heat source, which comprises: a case (221) having an air inlet (222) in one side thereof and an air outlet (223) in the other side thereof, having a space therein, and having a fifth heat exchanger (224), an evaporator (205), and an air blower (225) sequentially installed from the air inlet (222) therein; and a heating medium circulation part circulating a heating medium in a closed-loop formed when the fifth heat exchanger (224) is connected to a fourth heat exchanger (104) of which one side is connected between a first heat exchanger (102) and a first expansion valve (105), wherein the heating medium circulation part circulates the heating medium in order to emit the refrigerant heat at a high-temperature side into the case (221) through the fifth heat exchanger (224) after the heating medium absorbs the refrigerant heat at a high-temperature side through the fourth heat exchanger (104), so the air blower (225) can be operated to transfer sucked outdoor air to the evaporator (205) after the outdoor air is heated by the refrigerant heat at a high-temperature side in the case of a heating operation, or can be operated to quickly emit the refrigerant heat at a high-temperature side to the outside through the outdoor air in the case of a cooling operation.</p> |
