Abstract
When the first pressure reducing device is fixed to the accumulator tank and the internal heat exchanger is housed in the accumulator tank , the accumulator, the first pressure reducing device and the internal heat exchanger are integrated into one body. Due to the foregoing, it is possible to eliminate parts for piping to connect the first pressure reducing device with the internal heat exchanger . The mass of the vibration system of the first pressure reducing device including the accumulator tank and the internal heat exchanger is increased. Therefore, even if the valve body in the first pressure reducing device is vibrated, it becomes difficult for other portions to vibrate. Accordingly, it is possible to reduce noise (vibration) generated when refrigerant is decompressed by the first pressure reducing device
