PROBLEM TO BE SOLVED: To provide an air-conditioner capable of being mounted without washing existing pipes even under the conditions that foreign matters including a great amount of compressor wear debris, oil degraded materials and strong acid reside in internal and external connection pipes of the air-conditioner. SOLUTION: A refrigerating cycle has a plurality of strainers arranged in a refrigerant circuit and a compressor, a four-way valve, a condenser, a first electronic expansion valve, a liquid storage mechanism, a second electronic expansion valve, a liquid pipe, an evaporator, a gas pipe, and a four-way valve arranged therein in sequence. A dryer filter is provided between the second electronic expansion valve and the liquid pipe for trapping the foreign matters including compressor wear debris and oil degraded materials remained in the existing pipes.
