| Abstract: | Based on finite time thermodynamics theory,the performance analysis of an irreversible air heat pump was carried out by taking the heating load density as the optimization objective.The analytical formulae about the relations among heating load density,pressure ratio and the effectivenesses of the heat exchangers were derived.The influences of heat reservoir temperature ratio,heat exchanger inventory and the compressor and expansion efficiencies on the optimum distribution of heat conductance and the maximu... |
