近些年来,吸附式制冷受到了广泛的关注。本文针对再吸附制冷工质对MnCl_2/CaCl_2/NH_3进行了研究,针对不同的热源温度、冷凝温度、蒸发温度,测试了该再吸附工质对的循环吸附量,并且分析了COP,结果表明:当热源温度为130℃时,再吸附循环的理论COP为0.48~0.8,在测试工况下,当热源温度达到150℃,冷却温度为25℃以及蒸发温度5℃时,循环吸附量最大值可以达到0.502 kg/kg,对不同的热源温度、冷凝温度、蒸发温度条件下,MnCl_2/CaCl_2/NH_3的吸附量为0.184~0.502 kg/kg。
In recent years, adsorption refrigeration has received widespread attention. In this paper, MnCl_2 / CaCl_2 / NH_3 was studied for re-adsorbing refrigerants, and the cyclic adsorption capacity of the adsorbents was tested for different heat source temperatures, condensing temperatures and evaporating temperatures. The results showed that: When the temperature of the heat source is 130 ℃, the theoretical COP of the reabsorption cycle is 0.48 ~ 0.8. Under the test conditions, when the heat source temperature reaches 150 ℃, the cooling temperature is 25 ℃ and the evaporation temperature is 5 ℃, the maximum cyclic adsorption capacity can be Reached 0.502 kg / kg. The adsorption capacity of MnCl 2 / CaCl 2 / NH 3 was 0.184-0.502 kg / kg under different heat source temperature, condensing temperature and evaporation temperature.
