8月23日下午1：00-5：30，主题为"Natural Refrigerants Heat Pump System（自然制冷热泵系统）"在北京国际会议中心308会议室召开。

演讲内容摘要：

Metal hydride technology is extended to cooling applications with two coupled reactors filled with two different metal hydrides. Such a cooling module filled with two different metal hydrides LaNi4.7Al0.3 and MmNi4.15Fe0.85 is simulated based on heat and mass transfer aspects. Hydrogen is cycled from one reactor to another by supplying/removing heat to/from them. The effect of variation of heat source,heat rejection and refrigeration temperatures for various cycle times has been studied in the ranges of 160 to 200oC,30 to 50oC,10 to -10oC and 200 to 4000 seconds

respectively. Both COP as well as SCP is found to increase with increase in heat source temperature at low cycle time. The effect of heat rejection temperature is to decrease COP. The SCP is found to be more at a low heat rejection temperature. High COPs and SCPs are delivered by the cooling

module at higher refrigeration temperatures.

第22届国际制冷大会于2007年8月21日在北京国际会议中心隆重召开，会议为来自世界各地的科学家和工程师提供一个互相交流和分享各自成功经验的机会，以使制冷技术在今后几十年保持持续快速的发展。
