Refrigerator refrigerant r600a refill?

1, quantitative filling method quantitative filling method is simple, is to use a dedicated quantitative liquid receiver, according to the refrigerator R600A filled volume of the refrigerator is provided in the nameplate of refrigerant charging R600A refrigerants. 2, observe the filling method of observation can be summarized as 'two the three touch', namely refrigerators work: in an hour 1) The pressure gauge. Summer low pressure control in commonly 0. 05 million mpa - 0. 07 million mpa, control at zero in the winter. 02 million mpa - 0. 04 million mpa, the pressure is too high is refrigerator R600A freon add much, low pressure means less R600A refrigerants, need filling. （ 2) The frosting condition. If inside the refrigerator all frost that refrigerator R600A refrigerants and get about the same, if only partially frost refrigerator R600A refrigerant less, need filling. （ 3) With the hand touch. A, touch the temperature of the condenser. If the fridge R600A freon add too much, the condenser will be hot, too little will not fever; B, touch the low-pressure muffler. If muffler has a cool feeling, the normal, if back to the trachea frost, refrigerator R600A freon is overmuch, if the muffler is not cool, explain the fridge R600A refrigerant is insufficient, will need to refill this time; C, touch the filter, and the temperature of the capillary. If filter drier temperature is too high, the refrigerator R600A refrigerant too much, if there is a thermal, normal, if not a fever, refrigerator R600A snow kind of shortage. 3, current measurement method of current measurement method is to use ammeter monitoring current, when the current reaches rated current of the refrigerator, the refrigerator R600A refrigerant charging quantity is normal, if too large, the refrigerator R600A snow too much, if the current is small, the refrigerator R600A snow kind of shortage. Extension information: refrigerator refrigerant filling techniques: the refrigerator power is small, the refrigeration system is closed, is not easily out of order, normally no refrigeration condition, most of the reasons is the lack of refrigerant, need to 'add fluoride'. In the whole process of refrigerator maintenance as an important is how to accurate filling refrigerant, it is the key step of affecting the service life of compressor. If insufficient or injection too much water after sealing discovered, and have to deal with it again. Add excessive fluoride machine over time, serious muffler is icy, also cause compressor wet stroke, easy to damage the valve. The refrigerator temperature drop down, or slow cooling, easy to cause the machine doesn't stop, and refrigeration result is bad. Note too little, can't back to high temperatures, and the compression airland temperature ( Note: the refrigerator freezer compressor is to use the gas refrigerant to cool the back) Compressor is hot, high temperature lubricating oil metamorphism, easy to cause the compressor cylinder, further will burn compressor. Thus it can be seen that both blunt note more or less, will be easy to repair. After the general approach is to take time to refill gas tank balance and close the valve after about start refrigerator, running after all the freezer to cool to below zero, downtime. About three minutes later, boot up again. For about 20 to 60 seconds, compressor muffler can appear a frosting process, the frosting process lasts for about a minute long, and then melt. And after that, no longer frost, for filling. If this period of time, not a frosted process, filling quantity is less, need to add refrigerant. If the frost had not charging too much, need to be put off part of the refrigerant.
