<p>PURPOSE: An air conditioning apparatus using a heat pump system is provided to improve cooling and heating efficiency by forming an indoor air exhaust path inside the apparatus. CONSTITUTION: An air conditioning apparatus using a heat pump system comprises an indoor heat exchanger(60), an outdoor heat exchanger(30), an outdoor unit room(40), and an exhaust line(91). The indoor heat exchanger absorbs the heat of indoor air using refrigerants passing through an expansion valve in a cooling mode and discharges the heat of refrigerants passing through a compressor(10) to an indoor space in a heating mode. The outdoor heat exchanger discharges the heat of the refrigerants passing through the compressor to the outside in the cooling mode and absorbs the heat of external air using the refrigerants passing through the expansion valve in the heating mode. The outdoor unit room receives the outdoor heat exchanger therein. The exhaust line is connected between a ventilation system and the outdoor unit room.</p> |
