为提高扩散吸收制冷机（DAR）的电流循环性能，进行了研究。设计变化的热力学基础是重新利用整流器的余热来加热吸收器的弱吸收剂。设计并制造了一种新型的热交换器发生器。将GWHX雷达的测试结果与基线测试结果进行了比较。与基线测试相比，新设计的发电机在冷却能力不变的情况下，冷却效率显著提高了50%。
An effort was undertaken to improve the current cycle performance of the diffusion-absorption refrigerator (DAR). The thermodynamic basis for the design changes is to reuse waste heat from the rectifier to heat the weak absorbent from the absorber. A new generator with heat exchanger (GWHX) was designed and fabricated. The test results of the DAR with GWHX are compared with baseline tests. The new generator design demonstrated a significant improvement in the cooling COP of as much as 50% compared to the baseline tests while the cooling capacity was unchanged.
