The appearance of coins in the refrigerator often causes confusion among those who encounter this phenomenon for the first time. It seems that small metal items are completely out of place there, because this is not a food warehouse or a hiding place. However, behind this strange action there can be both deep esoteric beliefs and completely rational, albeit outdated, technical solutions.
In this article we will analyze in detail all aspects of this tradition. You will find out why our ancestors hid money in the freezer, how copper coins can affect the microclimate inside the chamber and whether there is at least some scientific sense in this. Separation of myths and reality It will help you understand whether this experience is worth repeating or whether it is better to leave the wallet alone.
Some owners of household appliances technicians still believe that such a ritual can protect a family from financial losses. Others argue that this is simply a way deodorization air through the oxidation of copper. Let's figure out which of this is true and which is just a relic of the past.
Folk signs and superstitions about money in the refrigerator
In Slavic culture, the refrigerator has long replaced the old wooden chest or underground, where the most valuable things were traditionally hidden. It is believed that cold preserves not only food, but also accumulation energy. A coin placed there becomes a kind of magnet that attracts new financial flows into the house.
There is a belief that if you put a coin in the freezer, the money in the family “will not run out,” since the cold “freezes” it and prevents it from being wasted. This method was considered especially effective if a coin was found or received as change without bargaining. Esotericists it is recommended to place bills or coins away from meat products so that the energy does not mix.
⚠️ Attention: Esoteric practices do not have scientific confirmation. The effectiveness of the ritual depends solely on your personal faith and psychological attitude. You should not expect miraculous enrichment just from the presence of metal in the freezer.
There is also an opinion that the clink of coins when opening the door scares away the evil spirits of poverty. If the coin lies quietly, it means there is financial stability in the house. If it constantly falls or makes sounds, expect unexpected expenses. Psychology The work here is simple: visualizing wealth, even in this form, sets a person up for a more careful attitude towards the budget.
Physical properties of copper and the fight against odors
If we put aside the mysticism, then there is a practical, albeit controversial, justification for placing coins in the refrigerator. Old coins were often made of copper or its alloys (bronze, brass). It is known that copper ions have bactericidal properties and are able to react with volatile compounds that cause unpleasant odors.
Inside the refrigerator, oxidation processes of products are constantly occurring. Volatile sulfur compounds, which give off the smell of rotten eggs or spoiled meat, can interact with the surface of a copper coin. A thin film of copper sulfide is formed, which is odorless. Thus, the coin works as a primitive odor absorber, similar to activated carbon, but due to a chemical reaction.
However, it is worth understanding that the surface area of one coin is negligible for effective air purification in a volume of 200-300 liters. For this method to work, you would need a handful of copper change spread out on all the shelves. Modern absorbents coal-based or special devices cope with this task much better.
- 🧊 Copper actually neutralizes some types of bacteria, but only with direct contact.
- 🍖 To combat the smell of fish or meat one coin absolutely not enough.
- ⏳ The process of oxidizing the surface of a coin takes time, there will be no immediate effect.
The influence of metal on the operation of the compressor and thermostat
There is a persistent but erroneous myth that coins can somehow stabilize the operation of the compressor or influence the thermostat readings. Some “masters” advise placing a coin on the relay or next to the temperature sensor, supposedly to improve thermal conductivity or electromagnetic background.
In fact, getting a metal object into the operating area of electrical components strictly prohibited. The vibration that inevitably occurs when the compressor operates can dislodge the coin. If it gets on the contacts of the starting relay or thermostat, a short circuit or false operation of the protection may occur.
The thermostat measures the temperature of the air or the surface of the evaporator. Metal has high thermal conductivity, so a coin lying next to the sensitive element can distort the readings, causing the unit to operate in the wrong mode. This will lead either to undercooling products or to the formation of excessive ice.
| Type of impact | Expected effect (myth) | Real result |
|---|---|---|
| To the compressor | Mitigation of work | Risk of short circuit |
| To the thermostat | Accuracy of readings | Distortion of temperature data |
| For microclimate | Preserving freshness | No effect (no chemical reaction) |
⚠️ Attention: Never place coins, foil or other conductive objects near electrical contacts, fans or defrost heaters. This can lead to damage to the electronics and a fire.
Coins as an indicator of defrosting and shutdown
One of the most rational ways to use a coin in a refrigerator is to create a simple defrosting indicator. This life hack is especially relevant for freezers where large stocks of meat, fish or semi-finished products are stored in case of long winter periods.
The essence of the method is as follows: you freeze a glass of water, put a coin on it and leave it in the freezer. If the power goes out for a long time, the ice will melt and the coin will sink to the bottom of the glass. Even if the light turns on again and the water freezes, the coin will remain below. Visual signal will immediately inform you that the food may have defrosted and spoiled.
This is especially important for those who go on long business trips or vacations. When you return, you will immediately see whether the temperature regime has been violated. If the coin lies on the surface of the ice, everything is in order, the equipment worked normally. If it drowns, the contents of the chamber require a thorough check for smell and texture.
☑️ Checking defrosting
What to do if the coin has sunk?
If you find that the coin is at the bottom of the glass, do not rush to throw away all the food. Check the meat: if it becomes flabby, changes color or has a sour smell, discard it. After repeated freezing, vegetables and fruits often lose their structure and become unsuitable for food, even if there is no smell.
Why modern models do not require “improvers”
The tradition of putting coins, coal or special bags of silica gel goes back to the times when refrigerators were simple insulated boxes with manual controls. Modern class units No Frost or Total No Frost equipped with complex air circulation systems.
In such models, the fan constantly drives air through the evaporator, where it is not only cooled, but also dried. Condensation and odors are effectively removed through the drainage system and, in some premium models, through special plasma filters or ion generators. The presence of a copper coin in such an air flow does not provide any additional effect.
Moreover, in refrigerators with a system Multi-Air Flow foreign light objects can be drawn into the air ducts, causing noise or blocking the dampers. Heavy coins are less dangerous, but also useless. Engineers have already provided all the necessary parameters for maintaining the freshness of products without the help of folk remedies.
- ❄️ No Frost systems regulate humidity themselves, eliminating the need for absorbents.
- 🔇 Foreign objects can disrupt the aerodynamics of air flows inside the chamber.
- 🛡️ Modern antibacterial coatings on shelves are more effective than any copper coin.
When a coin can harm equipment
Despite the harmlessness of a small piece of metal, in certain situations it becomes a source of problems. The main danger lies in mechanical damage to glass shelves or plastic containers. When loading heavy products, a coin can act as a fulcrum, creating excess pressure on the plastic, which will lead to a crack.
Another risk is that a coin gets into the condensate drain hole. In drip-type refrigerators, water flows down the back wall into a groove. If a small coin (for example, 1 or 5 kopecks) gets there, it can clog the channel. This will cause water to begin to accumulate at the bottom of the refrigerator or under the vegetable drawers, causing mold. corrosion and the appearance of mold.
It is also worth considering the chemical reaction. If the coin is dirty, oxidized, or has traces of glue, in conditions of high humidity and cold it may begin to actively deteriorate, staining food or the inner surface of the chamber. Rust from bimetallic coins can leave hard-to-remove marks on the white plastic.
⚠️ Attention: If you are using the refrigerator to store medications (for example, insulin), it is strictly forbidden to put foreign objects, including coins, there. This violates sanitary standards and can lead to contamination of medications.
Frequently asked questions (FAQ)
Is it true that a silver coin is better than a copper one for a refrigerator?
From a chemical point of view, silver has more pronounced bactericidal properties than copper. However, as with copper, the surface area of a single coin is too small to have a noticeable effect on the microflora inside the large volume of the refrigerator. The effect will be practically zero, and the risk of losing valuable metal will be real.
Is it possible to put coins in a new refrigerator to “start”?
No, this superstition has no technical basis. A new refrigerator does not need to be “activated” with metal. On the contrary, the operating instructions for most brands (Samsung, LG, Bosch) only require that you let the equipment sit after transportation and wash the internal chambers with water and a mild detergent before turning it on for the first time.
What to do if a coin fell behind the refrigerator?
If a coin fell into the gap between the refrigerator and the wall or under it, try to get it out so that it did not interfere with compressor ventilation. If it fell inside the case through the ventilation holes at the back, it is better to call a technician, since removing the back cover yourself may violate the warranty.
Does a coin affect power consumption?
It does not affect it at all. The coin is neither a heat insulator nor a conductor capable of changing heat transfer throughout the entire cabinet. Electricity consumption depends on the serviceability of the seals, the frequency of door opening and the set temperature, but not on the presence of metal objects on the shelves.
Is there an alternative to coins for eliminating odors?
Yes, there are much more effective and safe methods. Use activated carbon (can be in tablets, wrapped in gauze), special odor-absorbing balls, an open pack of soda, or even dry crusts of black bread. These products work on the principle of adsorption and actually clean the air without causing risks to equipment.
