随着国内货运市场对冷藏运输的需求越来越大，而且冷藏运输相对普通货运来说利润较大，许多从事普通货运的朋友也想涉及冷藏运输，那么冷藏车在使用时有什么需要注意的事项吗?今天新中昌冷藏车厂家就将冷藏车的秘密挖掘到底

　　● 装货之前 必须先要对车厢举行预冷或预热

　　在装货之前，必须先要对车厢举行预冷或预热1.5小时左右。因为车辆停放在露天，通常车厢温度就是外界环境的温度，一般来说所运送的货物温度不可能是环境温度，是的话就没必要冷藏车运输了。货物装进车厢，车厢里面的环境温度会波及运送货物的温度，从而导致运送货物的品质发生变化，所以装货前必须预冷车厢到所必要的温度。

　　● 关闭制冷机组装货卸货 冷藏箱温度流失更慢

　　在装货卸货时一定要关闭制冷机组，许多人在装卸货物时都是不关闭制冷机组，以为这样能让货物的温度上升更慢，其实这是一种非常错误的认识。

　　如果没有关闭制冷机组，当打开车厢门时，由于制冷机组蒸发器的风扇在工作，风扇将冷气从车厢上部吹出，而下部会将外面的热空气快速吸进来，从而导致车厢内的温度快速上升;如果关机后再装卸货物，由于风机处于停止状态，空气流动停止，车厢内外风压一致，外面热空气进入的速度更慢。

　　● 冷藏车不是冷库 冷冻机组主要是保温的

　　冷藏车不是冷库，在许多人的概念里冷藏车上的冷冻机组是可以随意将装入车厢内的货物冷冻或加热至其所必要的温度。其实冷冻机组是用来保持货物的温度，而不是用来降低货物温度的。有点类似过去卖冷饮时用的棉被，将货物包起来，当外界温度通过辐射、传导、对流进入冷藏车的厢体内，会被制冷机组吹出的冷气带走，隔绝热源进入货物。

　　As the domestic market of refrigerated cargo transport demand is bigger and bigger, and refrigerated transport relatively larger average freight profit, many engaged in ordinary freight friend also want to involved in refrigerated transport, refrigerated trucks in use from time to tome what items need to be aware of? Today a new secret mining chang will refrigerator car in the end

　　Low loading before must first on a carriage precooling or preheat

　　Before loading, must first on a carriage precooling or preheat 1.5 hours or so. Because vehicles parked in the open air, usually car compartment temperature is the temperature of the environment, in general the transport of goods can't be environment temperature, then no need for the refrigerator. The inside of the goods into the car, the car will environment temperature affected the temperature of the transport goods, resulting in delivery of the quality of the goods changes, so must be precooling carriage before loading to the necessary temperature.

　　Low closed refrigeration unit loading unloading cooler temperature loss more slowly

　　While loading unloading must close the refrigeration unit, a lot of people when loading and unloading of the goods is not closed refrigeration units, think this can let the cargo temperature rise more slowly, in fact this is a very wrong understanding.

　　If there is no closed refrigeration unit, when open the car door, because of the refrigeration unit evaporator fan is working, the fan will air conditioning blow out from above the cars, the lower will be the hot air outside quickly pulled in, leading to car temperature rising fast; If power off before loading the goods, because the fan is in stop state, the air flow stops, the car inside and outside air pressure, hot outside air into the speed is slower.

　　Low refrigerator car isn't a cold storage refrigeration unit is mainly thermal insulation

　　Refrigerator car isn't a cold storage, refrigerated trucks in many people's concept of refrigerating units are free to the goods will be loaded into the car frozen or heated to the necessary temperature. Actually refrigeration unit is used to keep the temperature of the goods, not used to reduce the temperature of the goods. Sold in the past similar to cold drinks in the quilt, wrapped up the goods, when the outside temperature by radiation, conduction, convection into refrigerator car compartments of the body, refrigeration unit will be blown away out of the air conditioning, isolation of heat into the goods.
