Parametric analysis on the performance of a revolutionary rotary Ericsson heat pump/engine

A revolutionary mechanical heat pump/engine system utilizing the Ericsson thermodynamic cycle has been proposed to provide efficient and environmentally friendly cooling. Computer simulation models have been developed to simulate the rotor positions. Further modeling has been conducted to predict the torque and power of the rotary Ericsson heat pump (REHP). Parametric and optimization study has been conducted to evaluate the factors affecting the mechanical and thermal performance of the conceptually designed REHP. It has been found that the rotor size, compression ratio and base pressure are the factors determining the maximum torque and power of the Motor-Generator (MG).
