钢板经环氧聚脂粉末喷涂而成,大盖(或门体)的外壳有的为彩板或覆塑板.制冷系统:压缩机,冷凝器,蒸发器,干燥过滤器,毛细管,为增加制冷速度及效果,有的加有风机来强制冷却.⑴压缩机是冰柜的心脏,它使冰柜的制冷系统完成连续的循环.其功能是为制冷剂在管路中的循环提供动力,将从蒸发器中吸收热量而汽化的低温低压制冷剂气体压缩为高温高压气体,排至冷凝器中.其质量的好坏直接影响到冰柜的制冷性能.压机外部接有工艺管,回气管,排气管.压缩机电机是一种单相交流感应电动机,主要类型及特性如下:类型电阻分相起动型电容起动型电容运行型电容起动运行型特征起动转矩较小,起动电流较大,结构简单,运行可靠,适于小功率压缩机起动转矩大,起动电流小起动转矩很小,适于起动负载小的压缩机起动转矩较大,功率因数高,适于大功率压缩机压缩机的种类有很多种,冰柜常用的有往复式(包括连杆式和滑管式)和旋转式两种.连杆式压缩机,电机通过连杆带动活塞作往复运动,结构复杂,装配困难,对零件几何精度要求高,但活塞受力情况好,工作可靠.滑管式压缩机通过滑管把电机轴的旋转运动转变为活塞的往复运动,结构简单,对零件的要求低,制造简单,但活塞受力情况差.旋转式压缩机体积小,零件少,效率高,对材料及装配加工精度要求高,工艺复杂.压机附件包括:启动器保护器⑵冷凝器又称散热器,是冰柜制冷系统中主要的热交换设备之一,其作用是把从压缩机排出的高温高压制冷剂气体的热量传递到外部环境而使制冷剂变成高温高压液体.其主要种类有以下几种:结构形式钢丝盘管式内藏式翅片盘管式冷却方式自然对流冷却强制对流冷却特点传热性能良好,整体强度好,材料费用低,焊接工艺较复杂.结构紧凑,便于清理,不易损伤管,可有效防止凝露现象结构紧凑,散热效率高,冷却能力强,需配置风扇安装位置冰柜背面卧式的四周,立式的两侧卧式机压机室内(逐渐代替内藏式)⑶蒸发器的作用是使制冷剂从毛细管进入蒸发器后,因压力降低而迅速蒸发,吸取柜内食品的热量使柜内食品温度下降,达到冷冻和冷藏的目的.其主要种类有以下几种:结构形式内藏式丝管式吹涨式翅片式特点结构简单,传热性能好,便于除霜结构紧凑,传热效率高,制冷性能好传热性能好,为铝板吹涨而呈单路或多路管路结构较紧凑,传热性能好,效率高冷却方式自然对流强制对流安装位置卧式柜内壳四周立式柜冷冻室内内壳后面(多为冷藏箱)冷冻室上部(多用于风冷式冰箱)⑷干燥过滤器的作用是干燥制冷系统中的水分并过滤杂质,防止因管路堵塞而使制冷系统发生故障.它由外壳,干燥剂,端档,过滤铜网等组成.壳内装有约8-15克的干燥剂,在靠近毛细管一侧装有一定目数的铜网,分别用于吸收水分和过滤杂质.干燥剂是一种叫做分子筛的物质.分子筛是具有晶体骨架结构和吸附作用的多水复合硅铝酸盐,是性能优异的高效能选择性吸附剂,冰柜所用干燥剂是其加入一定量的粘合剂塑合而成的环型分子筛.⑸毛细管的作用是节流降压,在压缩机运行过程中,保持蒸发器与冷凝器有一定的压力差,从而使制冷剂在蒸发器中低压蒸发吸热,同时使冷凝器中的气态制冷剂在一定的高压下放热,冷凝成液态.另一方面控制制冷剂的流量,使蒸发器保持合理的热度.毛细管是一种由紫铜管冷拔加工而成的内径约为0.6-1.0毫米的铜管,系统内制冷剂的流量与其长度有关,在管径一定的情况下,与其长度成反比.电器控制系统:温控器,起动元件,过热保护器,速冻开关,指示灯,电磁阀,风扇电机.⑴温控器的作用是用来调节和控制柜内温度.当温度控制器的旋钮设在一定位置时,压缩机运行,达到规定的温度后,温控器触点断开,切断压缩机的电源;当柜内温度回升后,温度控制器的触点接通,压缩机运行,从而使柜内温度保持在旋钮指定位置规定的范围内.温控器旋钮的位置不同,其所控制的温度范围也不同.常用的温控器有压力式温控器和电子式温控器两大类.压力温控器中的普通型温控器是目前冰柜使用最多的种类.其工作原理如下:温控器感温毛细管内充有R12或氯甲烷,其末端部分固定在发泡层内感温管内(或冷藏室内),感受温度变化.当箱内温度降低时,感温管内的气体压力减小,波纹管凹陷使主臂左移,带动触点快速弹开,切短压缩机电路,停止制冷:当箱内温度升高时,感温管内气体压力升高,通过转换机构使触点闭合,接通压缩机电路,以自动控制柜内温度.⑵起动元件冰柜,冰箱的起动元件包括起动开关和起动电容.起动开关主要有起动继电器和PTC起动器.①起动继电器是一种电流继电器,其常开触点串联在起动绕组回路中,电流线圈与主绕组串联.电动机接通电源后,比额定电流大几倍的起动电流,流入继电器的电流线圈而产生足够大的电磁吸力,使触点闭合,接通起动绕组回路,电动机起动.随着转速升高,起动电流减小.当转速升高到同步转速的75-80%时,继电器线圈中流过的电流减小到所产生的电磁力不足以维持触头的闭合,此时,触点打开,切断起动绕组回路,电动机起动完毕.② PTC是一种正温度系数热敏电阻,接入起动绕组电路中,可用作电机的起动器.它的工作原理是在电机接通电源的一瞬间,PTC中流过电流的时间很短,产生热量很小,因而温度很低,电阻值很小相当于短路(触点接通),起动绕组处于导通状态,致使压缩机起动运转.当达到额定转速后,由于电流的热效应,PTC起动器温度不断升高,当温度升高到50～60℃时,电阻急剧增大,相当于断路状态,压缩机起动绕组断路,完成起动.在正常运行时,仅有一个很小的电流通过PTC,使它继续发热(产生焦耳热),保持高阻值,使起动绕组保持断开状态.PTC起动器的优点是:无触点,不会产生火花干扰;过压,欠压时也能正常工作;无磨损,寿命长,无噪声;互换性好等等几方面.起动电容接在压缩机的起动绕组电路中,当压缩机起动时,电流流过起动电容,可获得较大的起动力矩,较小的起动电流.它只在起动的瞬间工作,通电时间一般只是几秒钟,因此多采用体积小,容量大,价格低的电解电容.⑶过热保护器的作用是当冰柜发生故障使压缩机过热或通过的电流过大时,其触点断开,切断压缩机电路,使压缩机免受损失.过热保护器有外接式和内埋式两种.外接式过热保护器串联在电路中,并与压缩机外壳接触良好.澳柯玛冰柜,冰箱一般使用此种过热保护器.附件:包括门拉手,铰链,铰链盒,万向轮,压机室护板,电器盒,除霜铲,控制板等等.冰柜,冰箱制冷原理及电器控制原理制冷工作原理电源接通后,压缩机压缩制冷剂为高温高压气体,流向冷凝器,在冷凝器散热成为低温高压液体,经过干燥过滤器吸收水分,去除杂质,再由毛细管节流降压为低温低压液体,然后流经蒸发器,吸收热量降低箱内温度,成为低温低压气体,最后流回压缩机,重新压缩.如此循环多次,直至达到要求的温度. 整个制冷循环过程可分为四个阶段:绝热压缩:压缩机将蒸发后的低温低压制冷剂吸入,这时气体的理想状态是充分气化,无液滴,稍微过热.经压缩机活塞的急剧压缩,对气体所做的机械功转化为热,使之变成高温高压气体.此过程很短,被升温气体的热量几乎没有传至外部,故称为绝热压缩过程.等温压缩:压缩机将高温高压气态制冷剂送至冷凝器冷却到其完全液化,这段时间放出冷凝潜热(液化热).在此过程只有状态变化,没有温度变化,故称为等温压缩.绝热膨胀:液态制冷剂在毛细管中受到节流作用,使液体压力急剧降至蒸发压力.制冷剂在此过程中温度虽剧降,但因时间也极为短暂,未能吸收外界的热量,故称绝热膨胀.等温膨胀:进入蒸发器的制冷剂迅速蒸发,不断从冰柜内吸收热量(蒸发潜热),直到液体完全气化为止,在此过程中,制冷剂的温度恒定,故称为等温膨胀.制冷剂及常用种类制冷剂是一种化学物质,在制冷系统的管路中,当制冷剂流入蒸发器时,处于低压状态迅速气化,由液体变为气体,并吸收被冷却物质的热量,经压缩机压缩排入冷凝器中进行冷凝,在冷凝时将所带热量传给冷却介质,还原为液体,再经毛细管进入蒸发器,如此循环不停,不断作用.在制冷系统中只有上述性质的物质,称为制冷剂或制冷工质.制冷剂在系统中的状态变化是物理变化,只起吸收和排放热量的作用,本身性质并不改变,如果系统没有泄露,制冷剂可长期循环使用.常用制冷剂的特性表R12R22R134a分子式CClF2CF2Cl2C2H2F4分子量120.986.48102.04沸腾温度(℃)-29.8-40.8-26.5凝固温度(℃)-158.2-160-101对润滑油的溶解性极易溶能溶不相溶可燃可爆性无无毒性等级65a使用温度(℃)10～-4010～-50臭氧破坏潜能1.00.0温室效应潜能2.8～3.40.24～0.29电器控制原理电路原理图工作原理:电源接通,绿色指示灯亮.当箱内温度高于设定温度时,温控器触点闭合接通压缩机,使压缩机工作,红色指示灯亮;当箱内温度达到设定温度时,温控器触点断开,压缩机停机,红灯灭.当按下速冻开关时,红黄指示灯同时亮,压缩机工作不停机.现在公司的产品,指示灯因系列,型号等的不同而不同,有的只有运行灯,有的有电源指示灯,速冻开关一般是标有(I,O)的开关(按下"I"速冻开关作用),三种指示灯都有的已不多见,具体情况请参照产品或最新产品说明等.第二部分冰柜的故障检测及维修检查冰柜故障的基本步骤冰柜维修前的准备工作首先检查冰柜是否按说明书要求,实行了可靠的接地措施,以保证维修及使用的安全.检查冰柜的电气接线各部分是否有脱落,断线及短路现象,如果有此类情况,应依次进行排除.检查冰柜整机的绝缘情况,维修中检查绝缘电阻应大于2兆欧,否则应进一步检查整机的阻值情况,将万用表调至R×1欧姆档,两只表笔分别接到冰柜电源插头的L,N两端,观察万用表指示情况,正常时应为数欧姆至几十欧姆之间.若阻值为零,说明冰柜电气接线处有短路现象或压缩机,风机等可能被烧毁,造成短路,应查明原因并排除.若阻值很大,甚至电路不通,说明有断路,也应进一步检查排除. 冰柜维修的基本步骤冰柜发生故障时,其症状总会以各种情况向外部反映.因此,对于有故障的冰柜,不要急于修复,应先对其进行仔细,彻底,全面的检查,然后再进行修理.一般可分为以下几个步骤:"一听,二看,三摸,四分析,五动手".·听①听取用户对使用过程中出现的各种情况的反映和诉述.②听压机运转的声音是否正常.在接通电源后,压缩机正常的运转声音是平稳和较小的,而有些故障会直接通过不同的声音表现出来.因此可据此进行判断,如:"嗡……"为压缩机电机未能正常启动;"嗒……"为压缩机内高压引管断裂或气流声;"当……"可能为压缩机内吊簧折断,压缩机倾斜运转;"镗……"或"哐……"是气缸的液击声;"贴嗒,贴嗒……"为压缩机内启动继电器没有吸合,出现以上情况应及时停止运行,更换压缩机.③听蒸发器管道内有无气流声或流水声,正常情况下在蒸发器管道进口处(即毛细管与蒸发器连接处),有清晰的"咝……"或"哗……"的制冷剂气流声或流水声,并且均匀,连续,打开柜门时应能听到这种声音.如听不到此声音或忽大忽小甚至断断续续,忽有忽无,则属不正常.说明制冷剂泄漏或不足.·看①看蒸发器(立式)或内胆(卧式)表面结霜程度.冰柜在正常工作状态下,内胆(或蒸发器)表面结霜的厚度应均匀,基本一致,如部分结霜,结霜不均匀,甚至完全不结霜,或结一种半透明的冰霜或凝结水,则为不正常,说明制冷剂不足或泄漏.②查看管路系统,特别是各焊接处是否有油渍.制冷剂有很强的渗透性,并且制冷剂内有少量冷冻机油,正常情况下应无任何渗油痕迹,如有渗漏则渗漏处会有油迹出现,则此处即为制冷剂泄漏部位. ·摸①摸冷凝器表面的温度,冰柜连续正常工作的情况下,其上部最热,甚至发烫(此温度与环境及季节性有关);下部温度接近或稍高于环境温度,且自上而下逐渐降温.如整个冷凝器不热,或上部仅有微热,或虽较热但上下相邻二根冷凝器管道有明显温度差异,则属不正常.②摸蒸发器(立式)或内胆(卧式)表面的温度,正常情况下应达到-18℃甚至更低,用手摸会有粘手的的感觉(注意动作要快,以防手被粘住),如手感觉不到冷或很微弱,则为不正常.③摸干燥器出口处毛细管部位的温度,正常情况下有微热感.(比环境温度高,与冷凝器末端管道温度基本相同),如感到比环境温度低或高的多,甚至冰凉或凝露,结霜则为不正常.④高压排气管的温度较高,用手摸时烫手或很热,低压吸气管的温度较低,夏天管壁有时结露,用手摸有冰凉的感觉,否则即为不正常.·分析根据看,听,摸过程得到的信息,经综合分析,正确判断是否有故障及故障的部位,性质,程度.·动手通过全面,正确的分析,确定维修的方法及具体步骤,对故障的部位进行拆,换,修复,并进行性能检验.常见故障的判断及维修冰柜不制冷冰柜不制冷可分为以下三种情况:⑴压机运转正常,不制冷.①制冷剂泄漏(外漏或内漏)判断:a.压机连续运转不停机b.蒸发器不冷,冷凝器不热,部分泄漏蒸发器部分结霜和冷凝器温热.c.蒸发器无气流声或流水声.d.压机外壳不热,长时间运行后比环境温度稍高,部分泄漏为温热.e.割开回,排气管无制冷剂排出或制冷剂排出少.维修:看管道各焊接处是否有油迹,有油迹处为外泄漏部位;充0.8MPa氮气,用仪器或肥皂水检查出外泄漏部位.对外漏处补焊,焊下过滤器以0.8MPa的氮气吹扫管路15秒钟,重新焊接工艺管,更换过虑器.充0.8MPa氮气用肥皂水检漏,抽真空,重新灌注R12.无外漏时,蒸发器充1.2MPa氮气稳定后保持24小时,回压超过0.15MPa(铝制蒸发器充不超过 0.8MPa氮气检),则判定为内漏.内漏冰柜处理需更换箱体(有经验维修人员也可把内漏点检出,如在冰柜C面靠近柜口处焊点漏可焊接好后重新把柜口安装好即可).详细维修步骤见维修工艺.②脏堵判断:a.压缩机连续运转不停b.制冷剂不能在系统中循环,使得蒸发器不冷,冷凝器不热,部分堵塞蒸发器有冰凉感觉,但无霜.c.蒸发器内无气流声.d.压机外壳不热,长时间运行后比环境温度稍高,微堵为温热.e.毛细管进口端(靠近干燥过滤器连接部位)或毛细管弯曲处有冰凉的感觉,冷的部位前端即为脏堵的部位,若为完全堵塞,附近有结霜现象.f.将过滤器出口端毛细管割开,一端或两端只微量气甚至不出气.且割开工艺管无制冷剂喷出,割开排气管有大量的制冷剂喷出.维修:焊下干燥过滤器,以0.8MPa氮气加10克R12吹扫蒸发器管路20秒,将其吹畅通.换过滤器,重新焊接,抽空,灌注R12.详细维修步骤见维修工艺.③油堵判断:a.压缩机连续运转不停b.制冷剂不能在系统中循环,使得蒸发器不冷,冷凝器不热,部分堵塞蒸发器有冰凉感觉,但无霜或少霜.c.蒸发器内无气流声.d.压机外壳不热,长时间运行后比环境温度稍高,微堵为温热.e.将过滤器出口端毛细管割开,管口有油随液气喷出;或过滤器侧连续出液气,毛细管端只微量出气甚至不出气.详细维修步骤见维修工艺.⑵压机运转不久,,过热保护器断开故障原因排除方法电源电压过高;过载保护器不良,跳脱过早;起动器触点粘接;压缩机内部有短路;压缩机内部机械故障;压缩机附近温度过高.安装稳压器,调至额定值;更换过载保护器;更换起动继电器;更换压缩机;更换压缩机;增大散热空间.各排除方法的详细维修步骤见相应维修工艺.⑶压机不运转.故障原因排除方法保险丝熔断;电源插头,插座,电源线接触不良内部断线;电源电压过低,低于187V;温度控制器旋钮在停点;温度控制器失灵;起动继电器或热保护器失灵或断路;电动机起动绕组或运转绕组断线;压机的电机烧毁或转子与定子卡死;压缩机高压阀片漏气或抱轴卡死.检查有无短路现象,有则排除,否则更换相应保险丝;检查并接牢,拧紧或更换;安装稳压器或待其升到额定值;将温控器旋到合适的位置;更换相应的温度控制器;更换起动器或过热保护器;更换压缩机;更换压缩机;更换压缩机;。
