Abstract:
1. An apparatus comprising: a cylinder in selective fluid communication with a compressed gas storage unit through valving; an element configured to effect gas-liquid heat exchange with gas expanding within the cylinder in an absence of combustion; a piston moveable within the cylinder to transmit power of expanding gas, out of the cylinder via a mechanical linkage, wherein the mechanical linkage comprises a shaft in selective communication with an energy source comprising a source of shaft torque to drive the piston to compress gas within the cylinder; a gas-liquid separator configured to receive a gas-liquid mixture from the cylinder; and a liquid conduit between the gas-liquid separator and a heating, ventilation, and air-conditioning (HVAC) system.
