kilograms of copper.
A refrigeration equipment that maintains a constant low temperature, and is also a civilian product that keeps food or other items at a constant low temperature. There is a compressor and an ice machine in the box.
Cabinets or bins for freezing, storage bins with refrigeration units. The volume of a household refrigerator is usually 20 500 liters.
In 1910, the world's first compression-type refrigerated household refrigerator was introduced in the United States. In 1925, the Swedish Lido company developed the household absorption refrigerator. 1927 General Electric Company of the United States.
A fully enclosed refrigerator was developed. In 1930, air-cooled continuous diffusion absorption refrigerators with different heating methods were put on the market. In 1931, a new type of refrigerant was successfully developed.
In the second half of the freon years, the production of household thermoelectric refrigerators began, and in China from the 50s, refrigerators began to be produced.
Internal cooling classification.
Forced circulation of air conditioner: also known as intercooled (air-cooled) or frost-free refrigerator. There is a small fan inside the refrigerator that forces the air flow in the box, so the temperature in the box is uniform, the cooling speed is fast, and it is easy to use. However, due to the defrosting system, the power consumption is slightly larger, and the manufacturing is relatively complicated.
Natural convection type of air conditioning: also known as direct cooling or frosted refrigerator. Its freezer chamber is made directly by the evaporator.
Enclose, or there is an evaporator in the freezer, and an evaporator is arranged in the upper part of the refrigerator, and the evaporator directly absorbs heat and cools down. This type of refrigerator has a relatively simple structure and low power consumption, but the temperature ineffectiveness is slightly worse, and it is relatively inconvenient to use.
Combined use of forced circulation of air conditioning and natural convection: This type of refrigerator is more commonly used in new products, mainly taking into account the advantages of air and direct cooling refrigerators at the same time.

The compressor has the most copper! Decompose and pull with three catties at least! Do you want to do it? Oh! If you sell it, the copper will be at least thirty pounds! Don't let it! People are pulling.

<> there is very little copper, most of it is the evaporator aluminum tube and the condenser iron tube connected head and tail, and the copper tube can be seen from the outside, about 50cm
Copper wire. The compressor has about 1 kg of piping.

Nowadays, there is almost no copper in refrigerators, and most of them are made of aluminum or iron.

Hello dear! The copper of an old refrigerator is about 2 or 3 catties of copper that can be removed: 1. Compressor process pipe; 2. a liquid storage bag; 3. Tubes on the heat exchanger of the tube sheet of the cold room; 4. a freezer plate heat exchanger; Now the refrigeration pipes of refrigerators are made of aluminum tubes or bondi tubes (bondi tubes are also galvanized steel tubes), so there is basically not much copper in the refrigerator now, I wish you a happy life.
-
It depends on what kind of refrigerator, generally up to three catties. Nowadays, the cheaper refrigerators are all aluminum tubes, basically no copper, and the compressor motor coil is a little copper, and the old compressor can be worth a little money when selling scrap, depending on the size of the compressor.
1. Introduction to refrigerator compressors.
At present, the compressors of household refrigerators and air conditioners are all volumetric type, which can be divided into reciprocating type and rotary type. The rotary type uses a rotating shaft crankshaft mechanism. According to the application range, it can be divided into low back pressure type, medium back pressure type and high back pressure type.
Low back pressure type ( evaporation temperature -35 15 is generally used in household refrigerators, food freezers, etc. Medium back pressure type ( evaporation temperature -20 0 is generally used in cold drink cabinets, milk refrigerators, etc. High back pressure type ( Evaporation temperature -5 15 It is generally used in room air conditioners, dehumidifiers, heat pumps, etc.
Reciprocating compressors use pistons, cranks, and connecting rod mechanisms or pistons, cranks, and slide pipe mechanisms.
Second, the working principle of refrigerator compressor.
1. Refrigerator compressor composition.
The refrigerator air conditioner is composed of four major parts: compressor, condenser, expansion valve and evaporator, according to the control or use of the need to choose to install pressure controller, temperature controller, filter drier and other auxiliary devices, but the four major pieces are a lot.
2. Liquid refrigeration.
When working, the gaseous refrigerant is compressed into a high-temperature and high-pressure gas through the compressor, and then enters the condenser, which is equivalent to a heat exchange equipment, which converts the high-temperature and high-pressure gaseous refrigerant into a low-temperature and high-pressure liquid refrigerant.
3. a throttling device.
The liquid refrigerant then passes through the expansion valve, the so-called expansion valve is a throttling device, because the refrigerant flowing out of the expansion valve is contained, so the refrigerant pressure decreases after it comes out, and the temperature continues to drop.
4. Heat exchange and gasification.
Then enter the evaporator, and the refrigerant at this time is reheated and gasified in the evaporator to become a gaseous refrigerant with high temperature and low pressure and return to the compressor to continue circulation.

There is not much copper, and some pipes are bondi pipes, that is, iron pipes are copper-plated and dismantled by themselves, so it is better to collect scrap. Of course, if you are not afraid of trouble, the compressor can be sold separately. But that's also an opportunity to sell.
-
Many of today's refrigerators are pipes made of aluminum. If it is a copper pipeline, it is about 1 kilogram.

Summary. Hello, dear. An old refrigerator has about kilograms of copper in it. Most of the refrigerators are evaporators, aluminum tubes and condenser iron pipes connected head to end, and copper pipes can be seen from the outside, about 50cm copper wires. The compressor has about 1 kg of piping.
Hello and get out, dear. An old refrigerator has about kilograms of copper left in it. Most of the refrigerators are evaporators, aluminum tubes and condenser iron pipes connected head to end, and copper pipes can be seen from the outside, about 50cm copper wires. The compressor has about 1kg of piping.
The refrigerator is a kind of refrigeration equipment that keeps a constant low temperature, and it is also a civilian product that keeps food or other items at a constant low temperature. The ridge of the box has a compressor, an ice machine for freezing cabinets or boxes, and a storage box with a refrigeration device. The volume of household lifts and refrigerators is usually 20 500 litres.

Summary. The amount of copper removed depends on the model and size of the old refrigerator. Generally speaking, an old refrigerator contains a certain amount of copper wires and tubes.
According to some estimates, the average old refrigerator may contain about 5-20 kg of copper. However, the specifics may vary, so it is best to have a professional or ** center for evaluation and dismantling operations. At the same time, local environmental regulations and policies should also be followed when it comes to ** metals.

Excuse me, but please go into more detail?
In general, an old refrigerator contains a relatively limited amount of copper. Typically, the main part of the refrigerator is made up of metal and plastic. Although there are some copper parts in the refrigerator, such as wires and pipes, the proportion of them is very small overall.
The copper in refrigerators is mainly used to make wires and condenser tubes. Wires are an important part of connecting power and control circuits in refrigerators, while condenser tubes are used in refrigeration circulation systems. The copper in these components is typically a high-quality condensed copper tube that is conductive and corrosion-resistant.
The amount of copper contained in each refrigerator will vary because different models and manufacturers of refrigerators use different materials and designs. But in general, the amount of copper removed from an old refrigerator is usually around a few kilograms. It is important to note that disassembling the refrigerator should be done safely and preferably by a professional.
During the disassembly process, the inside of the refrigerator should be properly treated, such as emptying the refrigerant and other harmful substances, to ensure environmental safety. In summary, although the refrigerator contains a small number of copper parts, the proportion of copper is small relative to the weight of the refrigerator as a whole. So the amount of copper contained in an old refrigerator is usually limited.
Hello! The refrigerant is sucked in by the compressor in the form of gaseous, compressed into a high-temperature and high-pressure vapor into the condenser through the exhaust pipe, and the refrigerant dissipates heat into the outside air, condenses into a high-pressure liquid, enters the capillary through the filter, and is intercepted and depressurized into the evaporator for vaporization. The refrigerant liquid absorbs external heat and vaporizes into dry saturated steam to cool down the refrigerator, and the refrigerant becomes low-pressure superheated vapor and is sucked back by the compressor, and so on.
Bananas, mangoes. This fruit is kept in the fridge and when you take them out, they will turn black. There is also bread, I have tried, the same bread placed outside and in the refrigerator, the outside is still very soft, the bread in the refrigerator is a little hard, and the taste is not as good as the bread outside.
1. The refrigerator should not be empty.
The refrigerator is closely related to the family's diet, and the food in the refrigerator is sufficient, which means that there is no need to worry about food and clothing; An empty refrigerator, on the other hand, has the undesirable inducement of poor economic conditions. So be sure to keep your fridge well stocked at all times. >>>More
