摘要: The finite-time thermodynamic performance has been studied of an endoreversible air heat-pump with constant-temperature heat-reservoirs. heating load, the coefficient (COP), and heating-load density, i.e. ratio load to maximum specific volume in cycle, are optimization objectives. analytical formulae relating pressure-ratio, between COP as well density pressure-ratio derived assuming heat resistance losses occur hot- cold-side heat-exchangers. influences effectiveness heat-exchangers heat-reservoir temperature-ratio on analyzed. cycle optimizations performed by searching optimal distribution conductance for fixed total heat-exchanger inventory. some design parameters, including heat-capacity rate working fluid, inventory conductance, indicated numerical examples. different results obtained from shown. design, heat-loading optimization, leads smaller size equipment.
