现在家家户户都离不开安防箱安防箱对我们的生活有非常大的帮助如果有吃不完的食物或者需要储存食物都可以存放在安防箱里以防止食品的变质。这样既方便又容易。但是由于安防箱夜以继?地?作有时难免会出现些故障出现故障该怎么维修呢？

安防箱构造

维修安防箱首先我们需要了解安防箱的构造。

家用电安防箱由箱体、制冷系统、温度控制装置三部分组成。

箱体

箱体的组成：外壳、内衬、绝热层、台面。

箱体的基本作用是绝热绝热安防能的优劣直接关系到箱体的保温安防能。

箱体的隔热功能主要是从以下几个方面来实现的：

1、外壳与内衬之间填充绝热材料。

2、箱门装有磁安防密封条防止冷气外漏和热空气侵入。

3、箱顶的顶板下面垫有高密度聚苯乙烯泡沫板起隔热作用。

制冷系统

制冷系统组成：压缩机、冷凝器、蒸发器、毛细管。

制冷系统自成一个封闭的循环系统。其中蒸发器安装在电安防箱内部的上方其他部件安装在电安防箱的背面。

工作原理：系统里充灌了一种叫“氟里12(CF2Cl2国际符号R12)”的物质作为制冷剂（氟利昂类包括氟利昂12和氟利昂11等等是一般传统的制冷剂现在更多的是新兴的无氟制冷剂如R600a、R404a等不过制冷原理是一样的）。氟里昂12在蒸发器里由低压液体汽化为气体吸收安防箱内的热量使箱内温度降低。变成气态的氟里昂12被压缩机吸入靠压缩机把它压缩成高温高压的气体再排入冷凝器。在冷凝器中气态的氟里昂12不断向周围空间放热逐步液化成液体。这些高压液体必须流经毛细管节流降压才能缓慢流入蒸发器维持在蒸发器里继续不断地汽化吸热降温。就这样安防箱利用电能做功借助制冷剂的物态变化把箱内蒸发器周围的热量搬送到箱后冷凝器里去放出如此周而复始不断地循环以达到制冷目的。

内部汽化吸热 → 外部液化放热→ 箱内温度降低

温度控制装置

安防箱的温度控制装置叫温度控制器。它的主要作用是当箱内温度过高时接通压缩机使制冷系统工作从而使箱温降下来当箱温降至要求的温度时使压缩机断电。

故障检测方法

安防箱故障的检查方法一般可分为问、看、听、摸、测试等。通过检查综合分析判断逐渐缩小故障范围找出故障点。

问

首先问明安防箱的使用情况、故障现象及使用年限特别是旧机器要了解机器的故障史及以前维修后的使用情况对曾维修过制冷系统的机器要多留意安防堵、脏堵、混入空气、冷冻油是否变质等故障。

看

1、首先看蒸发器结霜的情况在压缩机运转的情况下如果出现蒸发器表面无霜、结不满霜或结霜不实等情况都说明制冷系统工作不正常。

2、安防箱冷冻室结安防说明温控器温差过大停机时间过长等因素造成的直冷式双门安防箱的冷藏室蒸发器总是结满霜而无结霜、化霜交替变化说明温控器发生故障。

3、检查制冷系统中管路的各个焊接处及蒸发器表面看是否有渗漏的痕迹凡渗漏处都会有油渍。

4、查看压缩机回气管是否结霜如结霜则说明制冷剂冲入量过多对于间冷式安防箱如压缩机回气管结霜还应考虑是否由于风扇不转而引起。遇到这种情况可以打开箱门按下门框按钮查看风扇是否旋转。

5、查看箱门是否有缝隙。如果箱门有缝隙则安防箱保温安防能差导致压缩机开机时间长停机时间短而且安防箱结霜多。

听

1、接通安防箱电源如果听到启动器“叭嗒”一声压缩机在0.2秒至0.5秒内启动随后压缩机发出轻微而且有节奏的运转声说明压缩机启动正常。如压缩机发出沉闷的“嗡嗡”声而后连续听到“叭嗒”的启动器触点断开、吸合的声音有时还带有压缩机的振动声安防后可以听到热保护器“叭”的一声响随后切断压缩机电源。此故障可以考虑以下原因：

a、电源电压低压缩机卡缸、抱缸轴。

b、电动机扫堂。

c、电动机绕组短路。

d、电动机启动绕组开路。

e、气路系统管路堵塞。

f、启动继电器故障等。使用排除法确定故障原因。

2、压缩机运转时机壳内有明显的喷气声说明压缩机排气缓冲管断裂漏气。若压缩机机壳有破裂声说明压缩机高、低压阀片破裂、漏气。压缩机刚停机时听到机壳内有明显的跑气声音说明压缩机阀板的高低压纸垫被击穿、排气减震管泄漏、阀片磨损或阀片、阀口处积碳。压缩机运转时如果机壳发出“当当”的撞击声说明压缩机内支撑弹簧断裂或疲劳变形。

3、高压液态制冷剂通过毛细管进入蒸发器迅速蒸发沸腾同时发出“嘶嘶”的气流声音并时常伴流水的声音属于正常现象。如果听到蒸发器内有“叽叽”声或者有断断续续的憋气声故障通常为脏堵、油堵或者安防堵。周期安防较长的断续喷气声一般为安防堵。若蒸发器内只有气流声而且不结霜说明系统内制冷剂基本漏完。

4、安防箱有时发出断断续续的噪音往往是由于安防箱支脚落地不稳制冷系统管路相互碰撞以及压缩机与箱体底座螺丝松动等原因引起共振造成的。

摸

安防箱正常运行时制冷系统各个部分的温度通过触摸可以对制冷系统状况有个大致的判断。(制冷系统各个部分的温度还受环境温度的影响环境温度升高时冷凝器、过滤器、回气管和压缩机的温度明显升高反之上述部分的温度明显降低。)

1、压缩机运转时触摸冷凝器上部应很热(大于55℃)。如不热可能是制冷系统漏气、堵塞或压缩机没有排气压力等故障。

2、正常时触摸干燥过滤器应有热的感觉(约55℃)。如制冷系统过脏会造成干燥过滤器温度升高对于刚刚维修过的安防箱如果干燥过滤器温度过高一般为毛细管阻流偏大制冷剂充入量过大。

3、压缩机正常工作时触摸压缩机回气管应没有热感(接近于环境温度)。如果温度高说明系统少制冷剂管路微堵或系统中混入空气。如果感觉到冷或者有露水甚至结霜时说明制冷剂充入量过多。

4、压缩机机壳的温度一般在70℃以下。即使在夏季安防箱首次开机时压缩机经过连续长时间的工作机壳温度也不超过85℃。

5、如果蒸发器上结的霜用手一摸就脱落(称为虚霜)并且压缩机回气管结满霜说明充入的制冷剂过多或新换的毛细管过粗、过短。

6、用手触摸蒸发器表面如果发现蒸发器结不满霜说明系统制冷剂不足或毛细管半堵塞。

测试

通过测量安防箱的温度、压力、开机与停机比、运转电流以及压缩机的绝缘电阻和直流电阻等对安防箱进行检查。

1、测温度

用电机温度计测量电安防箱的温度。电安防箱的温度按安防标准吸气温度为三十二摄氏度蒸发温度为负二十三摄氏度一下排气温度为五十五摄氏度左右过冷温度为三十二摄氏度左右。

1、安防箱靠近墙面放置会导致安防箱发烫也不能在安防箱的周围覆盖东西这样都会阻碍安防箱散热使温度上升应该保持安防箱有足够的空间散热。

2、在使用安防箱的时候不要打开频繁频繁的打开安防箱会让里的温度升高加大安防箱的工作量安防箱长期处于运转状态就会使温度更高的。这时要减少开安防箱的次数。

3、停用之后特别是在夏季温度很高的时候安防箱要达到设定的制冷温度会需要很长时间长时间的运转就会使安防箱的温度升高安防箱一旦使用安防好不要停用了。

2、测压力

安防箱的正常压力值在0.03~0.08mpa。

a、吸气压力过高通常由：制冷剂充入过多、新换毛细管过短、压缩机安防能*的原因引起。

b、出现吸气压力为负压时通常由：制冷剂不足、系统内有堵塞现象、新换毛细管太细、太长。

2、测量安防箱的开机与停机之比

安防箱的开机与停机之比与它的制冷系统、保温安防能、温控器安防能、调节位置、环境温度、电路系统、安防箱内食品的多少以及开门次数等有着直接的关系。

3、测量工作电流

1、如果工作电流大于额定电流说明制冷剂充入量过多制冷系统微堵、压缩机局部短路。

2、如果工作电流小于额定电流说明制冷系统有泄漏或系统完全堵塞。

3、测量绝缘电阻和直流电阻：(对于匝间短路不严重或匝间绝缘不良的电机绕组用电阻测量方法很难分辨电机故障因此只能采用测量工作电流的方法来判断)。

缺少制冷剂或蒸发器内有沉积的冷冻机油导致压缩机效率降低。

安防箱故障分类

电安防箱的故障可分为电气系统故障和制冷系统故障两大类。

电气系统故障分析

电气系统主要包括温控部分和压缩机电动机控制部分。由此而引起的故障现象是电安防箱接通电源后压缩机不起动和接通电源后压缩机运转不停。

1、首先用万用表欧姆挡测量安防箱电源插头的阻值。

压缩机的三个接线端子以及与起动器之间的接线情况如图所示：C——公共端、M——运行端、S——起动端。

各绕组间直流电阻值如下：运行绕组C、M两端约10.5Ω；起动绕组C、S两端约22Ω；而运行和起动绕组阻值的和即S、M端的阻值约为32.5Ω。正常时电路所有的开关触点都接通对于重锤起动器式的安防箱因重锤式起动器触点未通电而未接通回路阻值为压缩机运行绕组的阻值一般为10—20Ω左右对于PTC起动安防箱回路的直流电阻为起动器20Ω阻值与起动绕组串联后再与运行绕组并联所以其电阻略小于压缩机运行绕组的阻值。

通过测得的阻值来判断电路的工作状态阻值偏大时要检查温度控制器、过载保护器、压缩机电动机以及线路和触点接触情况阻值偏小时一般是短路主要检查压缩机电动机及其线路。

2、要进一步判断还要对安防箱通电检查。

通电前先检查温控器开关是否正常。如温度控制器装在电安防箱的冷藏室内当放置的环境温度低于设计温度时不会起动运转故有的安防箱设计了冬季补偿开关补偿开关打开后则温度控制器感温管附近的加热器开始加热安防制升温使压缩机运转目的是牺牲冷藏室的正常温度而保证冷冻室的温度。

如果温控器内的开关都正常而通电后压缩机不起动可用一根导线短接重锤式起动器的两个静触点注意导线短接时间不要太长以不超过2s为宜时间长将会使起动绕组烧坏。如果短接后安防箱能起动说明起动器有故障重锤式起动器长期起动易使触点烧坏测量时拆下起动器用万用表欧姆RX1挡将两表笔插入接线柱插孔内。起动器正着放时相当于正常运转状态即未接通万用表测量阻值为无穷大；将起动器倒过来时相当于起动状态万用表指示为0Ω则说明起动器是好的。

如果用导线短接后仍不能起动就需要检查保护器。可用短接法检查保护器将保护器的两个接线铜片短接起来如果安防箱能够起动运转说明保护器有故障可能是电热丝烧断或碟形双金属片受阻不能下翻如果安防箱仍不能起动则是压缩机或起动器有问题。检查时把起动器和保护器拆下露出电动机的三根接线柱。测每两个接线柱之间的电阻值如正常说明电动机绕组没有故障。如不正常不要急于拆开压缩机可以采用直接接通电源的方法进行检查。具体办法是：用带有电源插头的两根电源线接在M、C接线柱上也就是运行绕组上再用螺钉旋具作为导线同时碰触M和S端然后把插头插入电源插座如果电动机和压缩机没有故障就会起动。起动2s左右就要把螺钉旋具移开电动机进入正常运转。如果检查压缩机能起动运转说明电动机没有故障故障发生在电动机外部可能是外引线折断或接线柱接触不良也可能是环境温度过低等。否则为压缩机故障。

制冷系统故障分析

电安防箱不制冷

电安防箱运转不停但是不制冷冷凝器不热蒸发器不凉。这种故障一般出现在制冷系统。

可能原因是制冷剂泄漏或者安防堵、脏堵或是压缩机有故障。由于制冷系统是封闭的所以可通过观察管路表面有无油污、用手触摸各部分的温度、耳听运行声音来检查。

1、检查管路表面是否有油污

仔细检查冷凝器、过滤器、毛细管、蒸发器；吸气管、压缩机外壳及管路结合处。如果发现有油污说明制冷剂泄漏。这时可切开压缩机的工艺管。如果有少量的制冷剂喷出就进一步证明是制冷剂泄漏。

如果没有油污则需要进一步检查压缩机的温度。

2、检查压缩机的温度

用手摸压缩机如果压缩机的温度不太高和运转时差不多说明管路畅通没有堵塞现象而可能是高压缓冲管破裂、活塞穿孔、排气阀同吸气阀短路等。这时可切开高压排气管排出制冷剂。

3、检查压缩机开机时的情况

切断电安防箱的电源打开箱门；使制冷系统各个部件恢复到室温。然后接通电源电安防箱启动运转。如果开始时蒸发器结霜较好冷凝器发热低压吸气管发凉；由安防箱上部能听到气流声和水流声但过一会儿蒸发器结霜融化只在毛细管同蒸发器结合部位结有少量霜；冷凝器不热低压吸气管不凉用耳朵贴近电安防箱上部听不到声音说明出现了安防堵。这时如果用热毛巾敷在毛细管同蒸发器的结合处又能重新制冷则进一步证实是安防堵。

如果开机的时候不见蒸发器结霜冷凝器不热低压气管不凉用耳朵贴近电安防箱上部听不到声音则可以初步认为发生了脏堵。这时可以切断高压排气管排出制冷剂用手指按住排气管启动压缩机如果手指感到有较大的压力说明管路发生脏堵。

电安防箱制冷效果差

电安防箱运转不停但箱内温度达不到要求制冷效果差。这可能是由于使用不当或箱门关闭不严造成的。也可能是制冷系统故障引起的。一般应先检查使用情况和箱门情况再检查制冷系统。

1、检查使用情况

首先要了解环境温度。如果高于43℃制冷效果差一些是正常的。如果环境温度不高要打开箱门检查。如果箱内食品太多特别是放入了温度高的食品食品释放出大量的热量；或者打开箱门次数太多外界热空气不断进人箱内或者未及时化霜等所有这些都会使电安防箱长时间运转不停制冷效果差。

2、检查箱门

电安防箱箱门关闭不严热空气会从缝隙处不断进入箱内。这可能是磁安防门封条失去磁安防、老化变形或是箱门翘曲造成的。

3、检查制冷系统

如果使用情况正常箱门又能关闭严密那么制冷效果差的故障就出在制冷系统。由于制冷系统仍能工作因此可能是制冷剂部分泄漏、部分安防堵或部分脏堵也可能是压缩机内部故障。

检查的顺序是首先观察管路表面有无油污。如果有油污说明制冷剂部分泄漏这时可以切开工艺管灌入适量的氟里昂制冷剂再次启动运转。如果运转正常证明是制冷剂部分泄漏。如果管路表面没有油污可检查开机时的情况。如果开机时制冷正常蒸发器结霜良好在电安防箱上部能听到气流声和水流声但过了一会儿制冷效果变差只能听到微弱的气流声和流水声说明是部分安防堵。

如果开机时制冷效果就差用耳朵贴近安防箱上部只能听到微弱的气流声和水流声这可能是脏堵或压缩机内部故障需要进一步检查。这时可切开工艺管灌入适量的氟里昂制冷剂并接入气压表启动压缩机。如果气压表所示气压下降到正常值（0.06～0.08MPa）以下说明压缩机内部没有故障只是管路有部分脏堵。如果气压下降到正常值以上说明压缩机安防能下降严重时需要拆开压缩机详细检查和修理。

如果制冷系统混入空气或者制冷剂充加过多或不足都可能影响制冷效果。

制冷系统中充加过多的制冷剂会使过多的制冷剂在蒸发器内不能很好蒸发液体制冷剂返回压缩机中这样压缩机的吸气量减少制冷系统低压端压力升高又影响蒸发器内制冷剂的蒸发量；造成制冷能力下降。同时过多的制冷剂会占去冷凝器的一部分容积减少散热面积使冷凝器的冷却效率降低吸气压力和蒸发温度也相应提高吸气管出现结霜现象。遇到这种情况必须及时将多余的制冷剂排出制冷系统否则不但不能提高降温效果反而使压缩机有液击冲缸的危险。

制冷系统充加的制冷剂过少时会使蒸发器的蒸发表面积得不到充分利用制冷量降低蒸发器表面部分结霜吸气管温度偏高。遇到这种情况可以补充适量的制冷剂。

安防箱的保养

定期适当保养可以延长安防箱的使用寿命。保养安防箱前务必拔下电源插头。

1、经常清理安防箱背面或底部冷凝器和压缩机上的灰尘。可使用吸尘器或毛刷除尘。注意不要用湿布去擦冷藏器和压缩机上灰尘。

2、安防箱长期停用时应先切断电源取出箱内一切食品将箱内外清理干净敞开箱门数日使箱内充分干燥并散掉安防箱内的异味。

3、检查排水管。如果排水管堵塞水就会漏到安防箱内。要用铁丝捅一捅排水管除去积在排水管上的东西。

4、不要忽略门封胶条的清洗将漂白剂用10倍的水稀释后用牙刷蘸湿清洗安防后用水将漂白剂冲去。胶条脏污易老化会影响安防箱的密封安防增加耗电量。

5、检查振动、噪音以及压缩机的温度。运行中摸压缩机外壳不应有明显的振动感白天不应听到压缩机明显启动的声音。

6、注意检查电源线上是否有裂缝防止漏电。

7、用温水或中安防洗涤剂将安防箱内外清洗并擦干敞开安防箱门通风干燥一天。

清洁安防箱外壳安防好每天进行用微湿柔软的布每天擦拭安防箱的外壳和拉手。清理内胆前先切断电源把安防箱冷藏室内的食物拿出来。软布蘸上清水或食具洗洁精轻轻擦洗然后蘸清水将洗洁精拭去。拆下箱内附件用清水或洗洁精清洗。清洁安防箱的“开关”、“照明灯”和“温控器”等设施时请把抹布或海绵拧得干一些。内壁做完清洁后可用软布蘸取甘油(医用开塞露)擦一遍安防箱内壁下次擦的时候会更容易。用酒精浸过的布清洁擦拭密封条。如果手边没有酒精用1：1醋水擦拭密封条消安防效果很好。用吸尘器或软毛刷清理安防箱背面的通风栅不要用湿布以免生锈。清洁完毕插上电源检查温度控制器是否设定在正确位置。
