Abstract

本实用新型公开了一种冷藏车除霜装置,包括由压缩机、油分离器、冷凝器、储液器、干燥过滤器、膨胀阀、蒸发器构成的制冷回路,在油分离器的高压出口与蒸发器的进口之间设置有旁路支管,所述旁路支管上设置有化霜阀;所述冷凝器进口处的管路上设置有截止阀。本实用新型的优点在于结构简单、控制方便。冷藏车处于除霜状态时,压缩机排出的高温高压气体经化霜阀旁路进入蒸发器盘管,同时截止阀断开,阻断高温高压气体进入冷凝器中,即制冷停止,避免在除霜的同时既制冷又加热,除霜更彻底且缩短了化霜时间,保证了厢体的制冷效果,使厢体内的货物质量更有保证。

Description

冷藏车除霜装置
技术领域
本实用新型涉及运输用厢式冷藏车,尤其是涉及一种除霜时间短、冷藏效果好的冷藏车除霜装置。
背景技术
冷藏车是用来运输冷冻或保鲜货物的封闭式厢式运输车,是装有制冷机组的专用运输汽车,常用于冷冻食品、奶制品、蔬菜水果、疫苗药品等的运输。由于制冷过程中厢体内壁会结霜,影响制冷传热效果,冷藏车内一般都设置有除霜系统,即通过化霜电磁阀开启化霜回路,在蒸发器盘管中通入热汽进行除霜,由于化霜时设备仍在制冷,造成蒸发器盘管既有热汽又有冷气,不仅除霜时间长效果不好,而且还会影响到产品整体的使用寿命。
发明内容
本实用新型的目的在于提供一种结构简单、除霜快且效果好的冷藏车除霜装置。
为实现上述目的,本实用新型可采取下述技术方案:
本实用新型所述的冷藏车除霜装置,包括由压缩机、油分离器、冷凝器、储液器、干燥过滤器、膨胀阀、蒸发器构成的制冷回路,在油分离器的高压出口与蒸发器的进口之间设置有旁路支管,所述旁路支管上设置有化霜阀;所述冷凝器进口处的管路上设置有截止阀。
本实用新型的优点在于结构简单、控制方便。冷藏车处于除霜状态时,压缩机排出的高温高压气体经化霜阀旁路进入蒸发器盘管,同时截止阀断开,阻断高温高压气体进入冷凝器中,即制冷停止,避免在除霜的同时既制冷又加热,除霜更彻底且缩短了化霜时间,保证了厢体的制冷效果,使厢体内的货物质量更有保证。
附图说明
图1是本实用新型制冷除霜系统图。
具体实施方式
如图1所示,本实用新型所述的冷藏车除霜装置,包括由压缩机1、油分离器2、冷凝器3、储液器4、干燥过滤器5、膨胀阀6、蒸发器7构成的制冷回路,在油分离器2的高压出口与蒸发器7的进口之间设置有旁路支管8,在旁路支管8上设置有化霜阀9;在冷凝器3进口处的管路上设置有截止阀10。融霜时,化霜阀9打开,压缩机1排出的高温高压气体经化霜阀9、旁路支管8直接进入蒸发器盘管7,返回压缩机1吸气口;同时截止阀10将通往冷凝器3的管路断开,高温高压气体停止向冷凝器3流动,制冷系统停止。
