Diagnosing method for clothes treating apparatus and clothes treating apparatus with refrigerant leakage detecting means

摘要

Disclosed are a method for diagnosing a clothes treating apparatus, and a clothes treating apparatus having a refrigerant leakage detecting means. In 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, and a compressor and an expander configured to constitute a heat pump together with the condenser and the evaporator, the method includes a temperature detection step of detecting a temperature change of air passing through the condenser or the air suction means, and a determination step of determining that refrigerant leakage has occurred when a temperature decrease amount measured in the temperature detection step is more than a predetermined level.
