<p>An evaporating device having a simplified outside-air intrusion prevention mechanism, capable of efficiently exchanging heat, and capable of suppressing energy consumption during its operation. A bypass line (Lc) in which a flow control valve (bypass valve (21)) is installed is branched (B3) from a vapor line for interconnecting the discharge side of a vapor compressor (2) and a vapor condenser (3). The bypass line (Lc) converges (B1) with a vapor line for interconnecting a dry container (1) and the suction side of the vapor compressor (2). The pressure in the dry container (1) (for example, a differential pressure between the pressure in the dry container (1) and the atmospheric pressure) is approximately the same as the atmospheric pressure.</p> |
