Systems, methods and devices for optimizing heat transfer within a device or system used to compress and/or expand a gas, such as air, are described herein. In some embodiments, a compressed air device and/or system can include an actuator such as a hydraulic actuator that can be used to compress a gas within a pressure vessel. An actuator can be actuated to move a liquid into a pressure vessel such that the liquid compresses gas within the pressure vessel. In such a compressor/expander device or system, during the compression and/or expansion process, heat can be transferred to the liquid used to compress the air. The compressor/expander device or system can include a liquid purge system that can be used to remove at least a portion of the liquid to which the heat energy has been transferred such that the liquid can be cooled and then recycled within the system.

The method of claim 11, wherein the portion of heated liquid transferred to the liquid purge system comprises a predetermined volume of liquid selected to remove a desired amount of heat energy from the compressor subassembly. 15. The method of claim 11, wherein the system further comprises a heat transfer element disposed within the working chamber of the pressure vessel, the method further comprising receiving, by the heat transfer element, heat energy from the gas being compressed. 16. The method of claim 15, further comprising transferring, by the heat transfer element, heat energy received from the compressed gas to the liquid in the working chamber of the pressure vessel. 17. The method of claim 11, wherein the compressor subassembly comprises a compressor/expander subassembly, the method further comprising: expanding gas in the working chamber of the pressure vessel to displace a second liquid from the working chamber to the hydraulic actuator and to transfer heat energy to the gas being expanded; andtransferring a portion of the second liquid from the compressor/expander subassembly to the liquid purge system. 18. The method of claim 17, further comprising transferring heated liquid to the compressor/expander subassembly to replace the portion of the second liquid transferred to the liquid purge system. 19. The method of claim 18, wherein the system further comprises a thermal management system fluidically coupled to the liquid purge system, the method further comprising heating, by the thermal management system, cooled liquid received from the liquid purge system. 20. The method of claim 11, wherein the system further comprises a second actuator coupled to the working piston and adapted to move the working piston in the first and second directions.
