本文介绍了热电和吸附循环的成功合并成一个组合的电吸附制冷机（EAC）。共生联盟产生的效率或COP（性能系数）超过三倍时，与他们的个人周期。在实验室规模的原型上进行的实验表明，它可以满足高冷却负载，通常为120 W，蒸发器占地面积为25 cm 2，即在22°C的加热表面温度下为5 W/cm 2，这远低于室温。EAC冷却器的COP在0.7至0.8之间变化，这与相同操作条件下约1.1的理论最大值相当。采用泡沫铜包覆蒸发器，在低温差下实现了高冷却速率。除了满足高冷却速率之外，EAC的独特之处在于（i）它几乎没有移动部件，因此具有静音操作，（ii）它是环境友好的，因为它使用无害的吸附剂（硅胶），以及（iii）水用作制冷剂。
The paper describes the successful amalgamation of the thermoelectric and the adsorption cycles into a combined electro-adsorption chiller (EAC). The symbiotic union produces an efficiency or COP (coefficient of performance) more than threefold when compared with their individual cycles. The experiments conducted on the bench-scale prototype show that it can meet high cooling loads, typically 120 W with an evaporator foot print of 25 cm 2 , that is 5 W/cm 2 at the heated surface temperature of 22°C, which is well below that of the room temperature. The COPs of the EAC chiller vary from 0.7 to 0.8, which is comparable to the theoretical maximum of about 1.1 at the same operating conditions. With a copper-foam cladded evaporator, the high cooling rates have been achieved with a low temperature difference. In addition to meeting high cooling rates, the EAC is unique as (i) it has almost no moving parts and hence has silent operation, (ii) it is environmentally friendly as it uses a nonharmful adsorbent (silica gel), and (iii) water is used as the refrigerant.
