PROBLEM TO BE SOLVED: To provide an accumulator which can separated a coolant to a gas and liquid, can store a liquid coolant, allows the passage of the coolant suppressed in pressure loss, and can discharge a lubricant stored therein.SOLUTION: An accumulator 32 is provided in an air-conditioning apparatus having a circulation path which circulates a coolant mixed with a lubricant, arranged upstream from a compressor 10 disposed on the circulation path and has a partition 68 as a gas-liquid separation means and a liquid reservoir space 50 for storing the coolant in a body of the accumulator. In the accumulator, the coolant flowing in from a first inflow port 54 passes through the partition 68, is separated into a gas and liquid, a liquid coolant and the lubricant are stored in the liquid reservoir space 50, meanwhile, a gaseous coolant is discharged from a discharge port 58, the coolant flowing in from a second inflow port 56 does not pass through the partition 68 and is discharged to the discharge port 58 via an introduction path 62, and an oil discharge path 70 which guides the lubricant from the liquid reservoir space 50 to the discharge port 58 is provided. |
