How it Works
Cool Energy’s novel low-temperature ThermoHeart Stirling Engines were designed for heat-to-electricity applications. We tap into a liquid or gas heat stream and convert it into mechanical energy to produce electricity. The ThermoHeart Engine differs from other Stirling engines because it can operate at lower input heat temperatures(150°C to 400°C). These engines are a new approach to the well-known Stirling cycle, employing a breakthrough engine configuration, low-cost materials, non-combustion, self-lubricating components, a nitrogen working gas, and very long service intervals. A Stirling cycle engine is a heat engine that operates by expansion and compression of air or other gas (called the working fluid), a temperature differential yields a net conversion of heat energy to mechanical work. The resulting mechanical work drives a generator built inside the ThermoHeart engine that creates electrical power (currently 3kW and 25kW output models).
