You will need
- - packing the valve;
- - oxygen-propane torch;
- tanks to the burner;
- and measuring devices;
- - a set of tools.
Free refrigerator - remove all food, remove shelves and drawers. Unplug the refrigeration unit from the electrical network and expand it in such a way to get free access to its rear side. It was there, in a niche on the metal traverse is the compressor.
Lift the compressor. Carefully bend the tube and slide the compressor forward to see 5-7 For steel pipe is not broken, if it should proceed with the greatest caution.
Will nantokite filling up and remove the freon from the cooling system. For this it is necessary to pinch the capillary tube and turn on the compressor of the fridge for 3 minutes. During this time the freonpresent in the unit, percacets in the condenser. Take a special piercing valve and hook it up to the filter-dryer. Connect a hose to otvaloobrazovanija tank followed by a filter-drier by connecting the selection valve. Open the cylinder valve for 30 seconds and collect the freon. Close the device.
Solder in place of the filling tube is copper. The length of the copper tube should be 6 cm, diameter - 6 mm. Soldering parts of the refrigerator can be done with a soldering iron, or air-propane torch.
Make the incision into the capillary tube. The incision should be placed at a distance of 3-5 cm from the filter-dehydrator. Break off the tube at the incision. Unsolder the filter drier from condenser and remove it.
Desolder the compressor from the suction and discharge tubes. Clean the old solder tube of the refrigerator and install a plug.
Remove the plugs from the new compressor. Wire connections of the compressor with the tubing of the refrigeration unit. Install filter drier to condenser, and insert a capillary tube. Solder the compressor. Carefully inspect the soldering joints on all sides with a mirror. Make sure that soldering is produced evenly and not left neproblem.
Advice 2: How to connect a refrigerator compressor
If you need a compressor, you can take this device out of an old refrigerator and adapted to the case. In this case it is important to connect to provide such a compressorhave a long and stable work.
Remove the compressor from the fridge. For this you may need to break the attachment. Then cut the tube (must be two of them) and the cable that connects to the temperature sensor. In this tester, measure the resistance of the cable and note the closed contacts, otherwise then it will be difficult to assemble a circuit. Removing the device, try to preserve the existing oil.
Turn on the compressorto make sure it is working. Check how it heats up and define the input and output. Further input will be possible to put a filter for cleaning air, and the output required install oil filter. For these purposes, you can take a simple car filter for fine purification of gasoline, which costs about 20 rubles.
Find regular serviceable relay. If you know the brand of the refrigerator, it is best to take relay from this device. Refer (if you got documentation on the fridge, the scheme can be viewed here: http://masterskie.info/elektroshema.htm) and connect it the same way as it was located on the fridge. In that case, if the winding in the engine is faulty, the relay will constantly disconnect the compressor and let it immediately burn.
Equip unit with a receiver. It can be easy to purchase, and you can do it yourself as follows: take an ordinary plastic bottle, twist the lid two holes and put in two pipes for input and output. Knead up some epoxy and pour it in a bottle. Close the bottle and flip it over. The resin is drained and permanently attach the cap with tubing to the bottle.
To connect the compressorand with the desired device, use the hoses for a washer that can be purchased in the shop.
Follow the oil level in the housing of the compressorand prevent it from overheating. Work time should not be more than 45 minutes.
Observe safety precautions when working with electrical appliances. Remember, all wires should be insulated, and all work can be done only with dry hands. No one can guarantee that a homemade compressor will run long and reliably, so it's easier to buy a device than to do it myself.
