Figure 5 Figure 10 reflects the COP,ralph lauren uk, with the pro-efficiency and cooling rate in the hot source temperature reactor and the quality of alloys and surface heat transfer coefficient than the case: in the hot source temperature will significantly reduce the COP, exergy efficiency and cooling rate,polo ralph lauren, so try to choose a lower temperature in the warm source; increase hydride mass ratio of the reactor can increase the COP and Gordon efficiency, but will reduce the cooling rate, so to select the appropriate reactor and the mass ratio of the alloy,tory burch uk, so Tianjin: Tianjin University , 2OO47 Zhou Mo Yan.

Engineering Thermophysics, 1994,15 (2): 123 128 to achieve the best dynamic performance of the system; increase the heat transfer coefficient will be significantly improved compared with COP, exergy efficiency and cooling rate, which may be through the development of new metal hydride reactor to address this issue. Besides changing the reactor heat capacity at constant pressure than on the COP, exergy efficiency and the rate of cooling is not obvious, so generally you can ignore the reactor than the heat capacity for the impact on system performance.
