Working Fluid

Steampowered - Steam Cycle
... this cycle a pump is used to pressurize the working fluid which is received from the condenser as a liquid not as a gas ... Pumping the working fluid in liquid form during the cycle requires a small fraction of the energy to transport it compared to the energy needed to compress the working fluid in gaseous form ... The working fluid in a Rankine cycle follows a closed loop and is reused constantly ...

Stirling Engine
... operating by cyclic compression and expansion of air or other gas, the working fluid, at different temperature levels such that there is a net conversion of heat energy to mechanical ... a closed-cycle regenerative heat engine with a permanently gaseous working fluid, where closed-cycle is defined as a thermodynamic system in which the working fluid is permanently contained within ...

Photovoltaic Thermal Hybrid Solar Collector - System Types - PV/T Liquid Collector
... In a standard chiller based system, a working fluid, typically water, glycol or mineral oil is then piped through these pipes or plate chillers ... from the PV cells are conducted through the metal and absorbed by the working fluid (presuming that the working fluid is cooler than the operating temperature of the cells) ... open-loop systems, this heat is used, or exhausted before the fluid returns to the PV cells ...

Steampowered - Efficiency
... The efficiency of a Rankine cycle is usually limited by the working fluid ... Without the pressure reaching super critical levels for the working fluid, the temperature range the cycle can operate over is quite small in steam turbines, turbine entry temperatures are typically 565°C (the creep ... work is required to drive the pump, the working fluid being in its liquid phase at this point ...
