II. commercial refrigeration condenser disassembly, diagnosis and maintenance
The condenser is a commercial refrigeration high-pressure pipeline with a relatively low failure rate. The exposed and shielded cooling costs; the shielded condenser can be disassembled and repaired: the built-in condenser cannot be disassembled or repaired if it is damaged, and the exposed condenser can only be installed on the back of the commercial refrigeration body.
1. The disassembly and assembly of the condenser is a schematic diagram of the disassembly of the exposed condenser. The refrigeration system is vented, and the two pipe ports of the condenser->-remove the fixing screws->-take off the condenser. Installation is the reverse process of disassembly. For shielded condensers, unscrew the fixing screws on the back panel of the commercial refrigeration to see the condenser.
2. Condenser diagnostic leak is the only form of damage to the condenser tube, and most of the leaks are at the welds and nozzles. 95% leakage at oily spots. commercial refrigeration is poor, and the refrigerant is discharged less when venting, but it suppresses the refrigeration system and maintains the pressure for 24 hours without leakage. Generally, the condenser has leaks. The condenser can be pressured by 1.2 MPa, and soapy water is applied to the suspected leaks. If there are bubbles, it means that there is leakage: if the pressure gauge value drops below 1.1 MPa after the pressure is maintained for 24 hours, it is necessary to judge whether the condenser is present Leak point. Of course, you can also use water immersion method to check for leaks.
3. Maintenance of exposed and shielded condensers. Leaks in exposed and shielded condensers can be repaired without the need to replace the condenser. Weld leaks and small weld leaks should be polished clean with emery cloth and repaired with brass electrodes. If a section of the weld is leaking, use a saw blade to remove the section of metal pipe, and weld a section of copper pipe with a diameter of 6 mm. [Note] If the commercial refrigeration condenser is replaced, the heat exchange area should be equal to or slightly larger than the prototype condenser.
4. The built-in type is changed to the exposed type. After confirming the leakage of the built-in condenser by the pressure method, select a condenser slightly smaller than the area of the back plate of the commercial refrigeration, and fix the condenser on the commercial with 4mm~6mm self-tapping screws On the back of refrigeration, the fixed position is usually the condenser fixed eye.
