【 Weak current College 】 refrigeration equipment-fridge library causes of ice barrier---Power By 【 China power house network 】

<br> <br> <br> Refrigeration equipment-fridge Library produces ice jam is a common phenomenon. ice blocking reasons are manifold: <br> <br> 1. refrigerant quality issues: due to years of leakage. cooling circulatory system, .the maintenance add refrigerant, the refrigerant is not pure, contains moisture. caused blockage. <br> <br> 2. refrigeration quality issues: refrigeration cycle, replaced refrigeration oil, lubricating oils do not contain pure, water. ice jam. <br .> <br> 3. compressor refrigeration cycle quality problem., in replacement of the compressor unit at compressor contains-water-ice barrier caused. <br> <br> 4. refrigeration cycle pipe leak caused problems: refrigerant ice barrier. refrigeration circulation .pipes due to trauma and oxidizing acid corrosion or thread connection loose or the formation of poor weld connection, short of refrigerant leakage, refrigeration equipment, refrigerating effect difference. making back to the steam pipe consistently negative pressure, air pressure is greater than the external environment .back to the steam tube pressure. wet air from leaking point leakage caused by inhalation of refrigeration cycle. ice jam. <br> <br> 5. maintenance measures: refrigeration cycle, in a long time to open when the maintenance is repair equipment, .pipeline not moistureproof processing. wet air enters the cooling cycle. caused blockage. <br> <br> Refrigeration equipment-fridge Gallery ice blocking solution <br> <br> Analysis of a refrigeration appliance-refrigerator Cabinet library causes of blockage, now a .one-to-one correspondence to: <br> <br> 1, refrigerant: refrigeration refrigeration cycle condition normal. refrigerating effect difference-high-pressure discharge pressure than normal value for the low, low-voltage back to the gas pressure is low .or normal value is negative. condenser when pressing than normal or tepid. supplementary refrigerant is in the process of opening and refrigerant cylinder connection pipe valve inline between a great cubic freezers with filters for the filtration of impurities in the refrigerant and residual moisture. may prevent .blockage of the filter as. 75 ¡ .æ ~ 100 ¡ .æ drying or replace the blue silicone can be reused. <br> <br> 2. replace the oil: refrigeration cycle, in the maintenance and replacement of refrigeration oil, first refrigeration oil heating with electric oven to 100 ℃ and maintain a constant temperature .for a period of time in the refrigeration oil not residual moisture to evaporate before replacing. can prevent blockage of the oil heating thermostat, prohibit the open fire and the workplace to a well-ventilated. takes note of the green. invalidity oil not carelessly dumping .. <br> <br> 3. replace the compressor unit: refrigeration cycle, in maintenance replacement compressor unit at compressor unit will be in the refrigeration oil down or evolve. step 2 on the refrigeration oil for dry processing-in refrigeration oil 75 ° .c plus. inhalation compressor unit shall be standard within. increase or decrease the amount of back-port-closed and mouth open send process porting. starting compressor running time-compressor heat generated from running under high temperature and pressure within the compressor was not completely .residual moisture evaporation from the rapid Assembly of finished then. <br> <br> 4. refrigeration cycle system piping problems: firstly to replace the damaged spot welding of pipe segments leaking and or tonic. Thread connection loose connection head redo and fastening. To .ensure that the pipeline pressure pressure detection without leakage. The refrigeration cycle pipeline pressure and low pressure stage four recorded rinse of carbon and nitrogen blow NET hold ready. There is also a method: is the leak spot repair leak-circulatory system piping via 75 ¡ .æ ~ 100 ¡ .æ vacuum drying and also to allow residual moisture evaporation emissions. compressor group must follow the steps 3 strict processing-replacement filters-and then blowing hold ready refrigeration cycle pipe breaks and quickly assemble complete compressor unit-then press step 1 for refrigerant quantitative filling. .wait five minutes (wait for the refrigeration cycle pipe of high pressure and low pressure area pressure static balance) power on the machine. <br> <br> 5. maintenance measures: refrigeration cycle in open maintenance work for a long time for non- .maintenance department is to seal or seal against moisture treatment maintenance department is to quick dismounting. and do not choose in rainy weather maintenance. <br> <br> 6. after the repair, minor blockage of refrigeration equipment: recyclable refrigerant, replacement filter, .and in high pressure exhaust-side in-line a great cubic freeze cabinet used filter. quantitative filling refrigerant. for freezer cabinets with 1000W tungsten iodine lamp baking (Note: the temperature is below 70 degrees centigrade). power on the machine of one hour .and then recycle refrigerants, remove and at high pressure exhaust-side in-line a great cubic freezers with filter, replace the new filters, new quantitative filling when recovering refrigerant. tanks refrigerant in tandem with a large cube frozen Cabinet filters to filter out impurities .in the refrigerant and residual moisture. to ensure the quality of the refrigerant. <br> <br> Refrigeration equipment maintenance: disable methanol! <br> <br> <br> <br>.
