本发明吸附式废热回收板式制冷器中板式制冷片3的具体制冷过程：The specific refrigeration process of the plate refrigeration plate 3 in the adsorption waste heat recovery plate refrigerator of the present invention:
第一，脱附、冷凝过程：高温废气废热通过加热盘管6，从而加热吸附/脱附区内的吸附剂7，使制冷剂脱附出来，脱附出来的制冷剂蒸气，通过制冷剂通道管a5管壁上的通孔流入制冷剂通道管a5，流过制冷剂通道管b10，进入冷凝/蒸发区。与此同时，冷凝空气流过冷凝盘管12，使脱附出来的制冷剂蒸气，在冷凝盘管12周围冷凝液化，并存储在蒸发盘管15周围；First, the process of desorption and condensation: the waste heat of high-temperature exhaust gas passes through the heating coil 6, thereby heating the adsorbent 7 in the adsorption/desorption area, so that the refrigerant is desorbed, and the desorbed refrigerant vapor passes through the refrigerant channel The through hole on the tube wall of the tube a5 flows into the refrigerant channel tube a5, flows through the refrigerant channel tube b10, and enters the condensation/evaporation zone. At the same time, the condensed air flows through the condensing coil 12, so that the desorbed refrigerant vapor is condensed and liquefied around the condensing coil 12, and stored around the evaporating coil 15;
第二，蒸发、制冷过程：当脱附完毕，蒸发盘管15周围充满了液态制冷剂，停止向加热盘管6通入高温废气废热；让大气空气通过加热盘管6，使吸附床快速冷却下来；待吸附床冷却下来后，空调空气通入蒸发盘管15使蒸发盘管15周围的液态制冷剂汽化，带走大量的汽化潜热，使流过空调空气的温度降低，从而达到制冷的目的。Second, the process of evaporation and refrigeration: when the desorption is completed, the surroundings of the evaporation coil 15 are filled with liquid refrigerant, and the high-temperature waste gas and waste heat are stopped feeding into the heating coil 6; atmospheric air is allowed to pass through the heating coil 6 to rapidly cool the adsorption bed down; after the adsorption bed cools down, air-conditioning air flows into the evaporating coil 15 to vaporize the liquid refrigerant around the evaporating coil 15, taking away a large amount of latent heat of vaporization, reducing the temperature of the air flowing through the air-conditioning, so as to achieve the purpose of refrigeration .
结合图7，采用两个本发明吸附式废热回收板式制冷器，组成连续交替的循环制冷系统。整个过程只涉及外部热气流(包括加热/冷却气流和冷凝/蒸发气流)流向的切换，而不涉及内部工质流向的切换，系统的内部制冷工质的循环制冷全部在各自板式制冷片3独立同步完成。其工作过程是：一个板式制冷器进行脱附、冷凝，另一个板式制冷器进行蒸发、制冷，这样两个板式制冷器通过相应的阀切换而交替工作，可以连续的提供冷量。连续交替的循环制冷系统利用本发明吸附式废热回收板式制冷器，实现了系统结构简单，密封性好、可靠性高且拆卸组装及检修方便。Referring to Fig. 7, two adsorption waste heat recovery plate refrigerators of the present invention are used to form a continuous and alternating cycle refrigeration system. The whole process only involves the switching of the flow direction of the external hot air flow (including heating/cooling air flow and condensation/evaporation air flow), not the switching of the flow direction of the internal working medium. Synchronization complete. Its working process is: one plate cooler performs desorption and condensation, and the other plate cooler performs evaporation and refrigeration. In this way, the two plate coolers work alternately through corresponding valve switching, and can continuously provide cooling capacity. The continuous alternating cycle refrigeration system utilizes the adsorption waste heat recovery plate refrigerator of the present invention to realize a simple system structure, good sealing performance, high reliability, and convenient disassembly, assembly and maintenance.
