Abstract: A clothing processing equipment includes a drum configured to accommodate laundry, a heat pump, and an air flow path defined between the heat pump and the drum, where the air flow path is configured to guide air circulating through the drum. The heat pump includes an evaporator, a compressor, a condenser, and an expansion valve and is configured to apply heat to air circulating through the drum. The condenser includes condensation refrigerant tubes configured to receive refrigerant and a condensation fin configured to conduct heat from the condensation refrigerant tubes. The evaporator includes evaporation refrigerant tubes configured to receive the refrigerant and an evaporation fin configured to conduct heat to the evaporation refrigerant tubes. The condensation refrigerant tubes define channels that are configured to carry the refrigerant. A cross-sectional area of each channel is less than a cross-sectional area of each evaporation refrigerant tube.
