A waste heat recovery system () is provided. At least one heat exchanger () is fluidically coupled to a waste heat source () and is configured for selectively recovering heat from the waste heat source () to heat a working fluid (). An energy conversion device () is fluidically coupled to the at least one heat exchanger () and is configured to receive the working fluid () and to generate an energy for performing work or transferring the energy to another device using the heat recovered from the waste heat source (). A condenser () is fluidically coupled to the energy conversion device () and configured to receive the working fluid () from the energy conversion device () and to condense the working fluid () into a liquid phase.
