To provide a purge device that can prevent a decrease in non-condensable gas separation efficacy even when a separation membrane is exposed to a liquid refrigerant.SOLUTION: This purge device comprises: purge piping that is connected to a condenser and purges mixed gas, which includes refrigerant gas and non-condensable gas, from the condenser; a separation membrane that is provided on the purge piping and separates the non-condensable gas from the mixed gas purged in the purge piping by means of a pressure differential; and exhaust piping that guides gas including the non-condensable gas separated by the separation membrane to the outside, wherein the separation membrane is a carbon membrane.SELECTED DRAWING: Figure 1 【課題】分離膜に液状の冷媒が接触しても不凝縮ガスの分離性能の低下を抑制することが可能な抽気装置を提供する。【解決手段】抽気装置は、凝縮器に接続され、凝縮器から冷媒ガスと不凝縮ガスとを含む混合ガスを抽気する抽気配管と、抽気配管に設けられ、圧力差によって抽気配管で抽気された混合ガスから不凝縮ガスを分離する分離膜と、分離膜で分離された不凝縮ガスを含む気体を外部に導く排気配管と、を備え、分離膜は炭素膜である。【選択図】図１
