Title: METHOD AND DEVICE FOR COMPRESSING A FLUID
Abstract:
The invention relates to a method for compressing a fluid, having at least the following steps: - providing a first container (11) with a liquid working fluid, a second container (12), and a compressing device (3) with a movable separating element (33), said separating element (33) separating a first and second gas chamber (31, 32) of the compressing device (3) from each other in a fluid-tight manner; - introducing (302) the fluid into the first gas chamber (31); - expanding (301) the working fluid into the second gas chamber (32), whereby at least one part of the working fluid transitions from the liquid aggregate state into the gaseous aggregate state; - reducing the volume of the first gas chamber (31) by moving the separating element (33), said movement being caused by the expansion work of the gaseous part of the working fluid; - discharging (303) the compressed fluid out of the first gas chamber (31); and - discharging (304) the expanded working fluid out of the second gas chamber (32) into the second container (12). According to the invention, the working fluid transitions from the gaseous aggregate state into the liquid aggregate state within the second container (12). The invention further relates to a device (1) for carrying out the method according to the invention.
