IIR documentSummary
Gas-fired heating is more environmentally friendly than coal-fired heating, but it results in extensive exergy loss because the heating supply temperature is much lower than the combustion temperature. We proposed a new gas-fired heat-driven thermoacoustic heat pump system. The SAGE program was used to simulate and optimize the system. With heating supply temperature of 333K and surrounding temperature of 273K, the system achieved a COPh of 1.72, corresponding to a relative Carnot efficiency of 44.43%. In addition, the simulation results also showed that the heat pump performance is sensitive to the system parameters.
