电冰箱ABC ①
                                                               
                                                                                 
电冰箱主要是由箱体、制冷系统、                                                      
电控系统及附件组成。                                                                
    1、箱体箱体由外壳、内胆及门                                                     
体等组成，用来隔热保持低温、存                                                      
放物品。一般箱体分隔成两部分，                                                      
即冷冻室和冷藏室。冷冻室的温度                                                      
很低，用于存放速冻食品及需长时                                                      
间储存的食品；而冷藏室温度为0℃                                                     
～5℃，用于存放鸡蛋、蔬菜等存放                                                     
时间短的食品。                                                                      
    2、制冷系统制冷系统由压缩机                                                     
、散热片、蒸发皿等部分组成。它                                                      
是利用制冷剂的循环，进行热交换                                                      
以达到制冷的目的。                                                                  
    3、电控系统由温度控制器和启                                                     
动继电器等电子器件组成。它的作                                                      
用是将电冰箱的箱内温度控制在一                                                      
定的范围内，以保证冷冻和冷藏的                                                      
要求。                                                                              
    4、附件附件包括制冰用的冰盒                                                     
、物品存放架、果菜盒等部件。其                                               
作用是方便食品的存放。                                                              

                                                                               
电冰箱ABC②
                                                                
                                                                                 
    一般情况下，电冰箱可分作直冷式                                                  
、风冷式和风直冷冰箱三大类。                                                        
    直冷冰箱是直接冷却式电冰箱                                                      
的简称。这类冰箱结构简单、降温                                                      
较快，耗能少，但冷冻室易结霜，                                                      
故又称有霜冰箱。                                                                    
    风冷冰箱为间接制冷式冰箱。                                                      
它是利用风扇强制冰箱内空气循环                                                      
流动，达到降温的目的。这类冰箱                                                      
的特点是冰箱内的温度较均匀，冰                                                      
箱内不结霜，但是耗电较大，冷藏                                                      
食品易风干。因其冰箱不结霜故又                                                      
称无霜冰箱。                                                                        
    风直冷冰箱的冷冻室采用风冷                                                      
方式，冷藏室采用直冷方式，这种                                                      
冰箱与风冷冰箱比较起来，其储存                                                      
的食品不易风干，是比较先进的无                                                      
霜冰箱。
