Refrigeration maintenance masters, please advise, refrigeration unit maintenance basic operation

If the vaporizer.

It's not called a condenser.

There is defrosting at the bottom (please make sure it is defrosted or if the refrigerant is not frosty enough?) ), prove that the defrosting system is working, and the defrosting time may be too short, for the following reasons:

1. The defrosting timer should be replaced with the same model or the same motor power supply connection;

2. The temperature of the bimetal sheet should be selected correctly, generally minus 7 degrees, and the installation position should be close to the buffer at the capillary outlet.

Above; 3. The power of the defrosting tube is not enough, and the defrosting is slow;

4. The door is not tightly sealed, causing too much moisture and too thick frost;

5. The position of the defrosting pipe is too high, which causes the ice plug of the drainage outlet to be poorly drained.

There is defrosting at the lower part of the evaporator, and there is frost accumulation at the upper part, indicating that the defrosting time is short, and the frost has not yet been melted, so it enters the refrigeration operation, so that the accumulation is more and more, causing the evaporator to be blocked by frost after a period of time. Check the power and position of the defrosted heating wire, and check whether the installation position of the bimetal sheet is too close to the heating element. The defrosting timer is generally rarely broken, and the nameplate parameter of the refrigerator has the power of the defrosting heating wire!

Problems with the controller! You can't jump to the specified temperature controller and can't start the defroster You can find someone to change to a controller that can set the time by yourself! Set yourself how long the refrigeration will take and how long the defrosting will take.

The power of the defrost tube is too small, and the position of the bimetal sheet is not good.

Refrigeration repair refers to the repair and maintenance of refrigeration equipment. Refrigeration equipment includes air conditioners, refrigerators, freezers, cold storage, etc. The refrigeration maintenance work mainly includes the following aspects:

1.Troubleshooting: Diagnose and troubleshoot faults in refrigeration equipment.

2.Maintenance: Perform regular maintenance on the refrigeration equipment, including cleaning, refrigerant filling, replacement of parts, etc.

3.Installation and commissioning: Commissioning and installation of newly installed refrigeration equipment.

4.Technical support: to provide customers with technical support and consulting services for refrigeration equipment.

Refrigeration maintenance requires certain technology and professional knowledge, and needs to hold the knowledge of refrigeration principle, electrical knowledge, mechanical knowledge and other aspects in the car. At the same time, refrigeration maintenance work needs to have the qualities of patience, carefulness, and responsibility to ensure the normal operation of refrigeration equipment and customer satisfaction.

Hello, I am happy to answer your questions, The basic operation of refrigeration unit maintenance includes the following aspects:1Shutdown Check:

Before the refrigeration unit can be repaired, it is first necessary to stop the unit to ensure that the unit has stopped operating and that the power and air supply have been cut off. 2.Check for failures:

Before carrying out repairs, a full inspection of the refrigeration unit is required to determine the specifics and location of the fault. Faults can be determined by observing, listening, smelling, and other ways. 3.

Troubleshooting: Different troubleshooting measures are required for faults of different fiber rollers. For example, in the case of a refrigerant leak, the leakage needs to be identified and repaired by inspecting the pipes, valves, and other parts.

4.Replacement of parts: Some damaged parts may need to be replaced during the troubleshooting process.

Before replacing parts, it is necessary to understand the model and specifications of the parts, and pay attention to the correctness and safety of the operation. 5.Commissioning unit:

After the completion of the repair, the unit needs to be commissioned to ensure the normal operation of the unit and achieve the expected cooling effect.

What are you asking, can you write in more detail? There's nowhere to start!

That's too broad.

I know that there are enthusiastic netizens who can help you solve a certain problem, but I can't give you a lecture.

Dear landlord:

If the refrigerator is not refrigerated, it is recommended to troubleshoot the fault:

1.whether the refrigerant is leaking or the refrigerant is insufficient;

2.System pipeline blockage (compressors, solenoid valves, capillaries, filter driers, etc. should be investigated);

3.The thermostat setting is too low or the room temperature is too high;

4.Excessive and overloaded food in the room at one time, resulting in obstruction of air inlets and outlets or sensors, affecting the circulation of air-conditioning;

5.Is the door closed tightly, and is there any aging and cold leakage in the door seal?

6.Is there a 10 cm ventilation space around the refrigerator? Is it close to a heat source?

The above are all culprits that may cause the refrigerator to not refrigerate, and it does not cost money to eliminate it yourself; If you can't rule it out by yourself, you need to point to the local after-sales service, and you can only confirm it after identification. This ** includes spare parts, material costs and on-site service fees.

Hope it helps.
