<p>Disclosed are a clothes treating apparatus with a heat pump and an operating method thereof. For a clothes treating apparatus comprising a drum configured to accommodate therein an object to be dried, an air suction means configured to form a flow path of air introduced into the drum, an air exhaustion means configured to form a flow path of air exhausted from the drum, a condenser disposed to heat air sucked into the drum through the air suction means, an evaporator disposed to cool air exhausted from the drum through the air exhaustion means, a compressor configured to compress a refrigerant introduced from the evaporator, and a variable expander configured to expand a refrigerant introduced from the condenser, and having a variable open degree, the operation method includes measuring a temperature (Tei) of a refrigerant introduced into the evaporator, and a temperature (Tci) of a refrigerant introduced into the compressor, and decreasing an open degree of the variable expander when a temperature difference (Tci-Tei) between the two measured temperatures is less than a predetermined first value, wherein in the step of decreasing the open degree of the variable expander, an open degree decrease width when the open degree is small is set to be narrower than that when the open degree is large.</p> |
