The invention discloses a refrigerating unit and a refrigerator car, the refrigerating unit comprises a condenser, a liquid storage device, a drying filter and a liquid viewing mirror, the condenser is provided with a refrigerant inlet and a refrigerant outlet, and a refrigerant flows in and out of the condenser through the refrigerant inlet and the refrigerant outlet; the liquid storage device is installed on the condenser and provided with a liquid storage cavity, a cavity inlet and a cavity outlet. The chamber inlet communicates with the condenser and the liquid storage chamber, so that a refrigerant for superheat exchange in the condenser is input into the liquid storage chamber through the chamber inlet; the cavity outlet communicates with the liquid storage cavity and the condenser, so that a refrigerant in the liquid storage cavity is input into the condenser through the cavity outlet; the drying filter is mounted in the liquid storage chamber to filter and dry at least part of the refrigerant flowing through the liquid storage chamber; the liquid viewing mirror is installed on the side wall of the liquid storage device and communicates with the liquid storage cavity. According to the application, pipeline connecting points are reduced, so that the risk of refrigerant leakage among the condenser, the liquid storage device, the drying filter and the liquid viewing mirror can be reduced.
本申请公开了一种制冷机组及冷藏车,制冷机组包括冷凝器、储液器、干燥过滤器和视液镜,冷凝器设有制冷剂入口和制冷剂出口,以供制冷剂流入及流出冷凝器;储液器安装于冷凝器,储液器设有储液腔室、腔室入口和腔室出口;腔室入口分别与冷凝器和储液腔室连通,以将冷凝器内进行过热交换的制冷剂通过腔室入口输入储液腔室;腔室出口分别与储液腔室和冷凝器连通,以将储液腔室内的制冷剂通过腔室出口输入冷凝器;干燥过滤器安装于储液腔室,以过滤和干燥至少部分流经储液腔室内的制冷剂;视液镜安装于储液器的侧壁,且视液镜与储液腔室连通。本申请减少了管路连接点,从而能够降低冷凝器、储液器、干燥过滤器和视液镜之间的制冷剂泄露风险。
