| 20090272518 | Air Conditioner Having Cooling and Heating Functions - Disclosed is a cooling and heating air conditioner capable of performing heating more stably, preventing frost formation on coils of an outdoor unit even at subzero temperature in winter by using first and second heat exchangers and an auxiliary expansion valve. The air conditioner according to the present invention comprises an electronic control valve opened when the outside temperature is less than a preset value, a first heat exchanger performing heat exchange between high temperature liquid coolant and coolant passed through the outdoor unit and an auxiliary expansion valve, and a second heat exchanger disposed in front of the outdoor unit to induct thereinto the high temperature coolant. Since the second heat exchanger heats up the outside air through heat exchange before supplying the air to the outdoor unit, evaporation of the coolant can be stably performed in the outdoor unit, while preventing frost formation. Accordingly, heating can be performed constantly. | 11-05-2009 |
