PROBLEM TO BE SOLVED: To provide a refrigeration cycle device capable of surely completing defrosting by detecting abnormality when switching abnormality occurs to a three-way valve.SOLUTION: A refrigeration cycle device includes three-way valve temperature detection means 50 for detecting a temperature in a path between a three-way valve (a switching device) 42 and a heat storage heat exchanger (an auxiliary heat exchanger) 34. During a defrosting/heating operation, when difference between a temperature detected by outdoor heat exchanger temperature detection means and a temperature detected by the three-way valve temperature detection means 50 is below a predetermined temperature, the three-way valve is determined to be abnormal, and the defrosting/heating operation is stopped. |
