To provide an air conditioner capable of preventing lowering of coolant condensing efficiency of a condenser.
This air conditioner includes a compressor, the condenser, an inflation valve, an evaporator, an intermediate heat exchanger 10 performing heat exchange between high pressure coolant flowing out of the condenser and low pressure coolant flowing out of the evaporator, and a liquid reservoir part 20. The intermediate heat exchanger 10 includes an outer pipe 13 and an inner pipe 14 arranged with a space in the outer pipe 13. A clearance between the outer pipe 13 and the inner pipe 14 is made as a high temperature side coolant passage 11, while the inside of the inner pipe 14 is made as a low temperature side coolant passage 12. The high temperature side coolant passage 11 includes a coolant inlet 15 and a coolant outlet 16. The inside of the high temperature side coolant passage 11 is divided into a coolant inlet side portion 11A and a coolant outlet side portion 11B. The liquid reservoir part 20 includes a coolant inflow port 22 and a coolant outflow port 23. The coolant inlet side portion 11A and the coolant outflow port 22 in the high temperature side coolant passage 11 and the coolant outlet side portion 11B and the coolant outflow port 23 in the high temperature side coolant passage 11 are led, respectively.
