OUTDOOR HEAT EXCHANGER FOR HEAT PUMP AND HEAT PUMP USING THE SAME

摘要

PURPOSE: An outdoor unit coil of a heat pump and a heat pump using the same are provided to enhance the condensation performance by using an outdoor unit coil as a condenser while cooling and enhance the evaporation performance by using the outdoor unit coil as an evaporator while heating. CONSTITUTION: An outdoor unit coil of a heat pump performs a heat exchange of outdoor air and refrigerant. The outdoor unit coil comprises a first row coil(260-1) and second row coil(260-2). The first row coil is formed into a dual pipe shape firstly contacted with outdoor air. The second row coil is installed in a side of the first row coil side by side and contacted with the outdoor air relatively later than the first row coil.
