演讲内容摘要：
It is well known,that the power consumption of refrigerators is reduced by about 2-3 %,when the evaporation temperature is increased by 1 K. It is proposed to obtain such an increase of the evaporation temperature by a combination of an internal heat exchanger in combination with a thermostatic expansion valve. With this combination it is possible to realize a slightly wet outlet of the low pressure stream out of the evaporator and to transfer the final evaporation and the superheating into the internal heat exchanger. To facilitate a stable control behaviour it is proposed to operate the internal heat exchanger in the co-current mode. The result of this arrangement is a power saving in the 5 to 10% range and a similar increase of the volumetric refrigeration rate. A further increase is possible,if the surface area of the evaporator is increased.
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。
