When the refrigerator is manufactured, the folding plate is punched first, and then the condenser is laid on the back plate of the refrigerator. After simple fixing, load the materials on the inner walls of the refrigerating room and freezing room, and install the evaporator at the same time. When this is done, start foaming with a hair dryer. Then plastic installation of other parts, such as doors, seals, partitions and so on. In the process of assembling the refrigerator, there is no step of installing the solenoid valve. Moreover, the pipes are made in advance and will be wrapped after foaming, so the pipes cannot be replaced.
The last step is to install the compressor on the production line. First, fix the compressor at the bottom of the refrigerator with bolts, and then wire it. Finally, connect the suction pipe and exhaust pipe of the compressor to the evaporator and condenser of the refrigerator respectively, and weld them with silver-plated covered electrode. The solenoid valve will not be used in this step.
