Abstract
We have established a macro/nano refrigerator model. A possibly new thermodynamic refrigerator based on thermosize effects is analyzed. Expressions for some important parameters, such as the refrigeration load, coefficient of performance, and work input, are derived. By means of numerical calculation and illustration, the influence of the thermosize effects and the additional regenerative loss on the performance of the cycle are discussed and evaluated in detail. Some fundamental optimal relations and general performance characteristic curves of the cycle are obtained. The results obtained here will provide theoretical guidance for the design of some new macro/nano scaled devices.
