Well, i'm just a market man who brings you up to date every day
Almost all households have refrigerators, and during their daily use, many find a phenomenon: when the refrigerator works, both sides of the shell feel warm, and even in the summer high temperatures, it becomes apparent. Many people are panicking about the situation, fearing that the refrigerator will fail, fear that excessive temperatures will cause short circuits, fires and even explosions, and that electricity will be removed frequently and not used properly。
In fact, the refrigerator is hot on both sides, and the vast majority of cases are normal physical phenomena, not machine damage, and less explosive security incidents. Many people, who do not understand the workings of refrigerators, treat normal heat dispersion as a malfunction, as a source of anxiety, and some who ignore abnormal heating signals and overload over a long period of time, do pose safety risks. Today, together with the principles of running household electricity, national standard safety norms and daily use scenes, the causes of burning on both sides of the refrigerator, the criteria for distinguishing between normal and unusual conditions, whether there are security risks, and the solutions that ordinary people can operate on their own, so that they can avoid the error zone。
First, understand the core principle: the fridge is hot on both sides, and it's just normal. Hot
Many people have a cognitive error with refrigerators, which they feel are “cooling” devices, which are cold inside and should not heat up. The working logic of the actual refrigerator is that of a heat handling machine, which does not produce low temperatures in a vacuum, but is continuously shifting internal refrigerator food, air heat, through compressors, refrigerant cycles, to the outdoor environment。
When compressors for the core parts of refrigerators operate, refrigerants are compressed into high-temperature, high-pressure gases that flow into the condenser pipelines placed inside the boxes on both sides of the refrigerators, heat is released into the air through metal casings, heat cooling is done, then refrigerants are recycled back to internal heating. The heat on both sides we touch is the visual expression of the heat released out by the condenser, which is the same thing as the heat blowing out of the air conditioning room。
In accordance with the performance criteria of the gb/t 8059 refrigerators, in normal working conditions, the temperature of both sides of the refrigerators falls within a reasonable range at 40°c-50°c, which rises to 50-60°c in the summer when the temperature is high, the refrigerator is just opened and a large amount of food is put in at once, and as long as the cooling effect is normal, it is a work permit and is not a malfunction at all. The old refrigerator condensers are mostly designed on the back, and the new home refrigerators, in order to save space, mostly embed the condensers in both sides of the box, so that the heating on both sides is more visible than on the back, which is the normal difference in the machine design。
In short, the temperature and even mild fever on both sides of the refrigerator suggests that the cooling system is working properly, that the heat can be discharged smoothly and that the machine is operating steadily. The risk of failure needs to be monitored only when there is an abnormally high temperature associated with the failure of cooling, non-stop, etc。
Ii. Explosion and fire? Distinguishing normal heat and dangerous heat
The most important concern is whether burning on both sides could trigger an explosion or a fire. From the point of view of household electricity security, there is no explosive risk at all because of the simple normal dissipation of heat and heat; only a combination of chronic dissipation, ageing parts and faults of circuits can increase the safety risk, and the refrigerators normally used are extremely low for extreme accidents。
On a daily basis, a rapid distinction can be drawn between normal heat and dangerous abnormal heat:
First, temperature. Normal heat is warm and hands can be placed on the outer shell for long periods of time, except when they feel hot; abnormally hot hands are burned and the skin is touched for seconds, and the temperature exceeds 60°c, which cannot be cooled for long periods。
Second, compressor is operational. The normal refrigerator compression opportunities are intermittent, working for 10 minutes to 20 minutes and resting for about half an hour; when the heat is abnormal, the compressor continues to operate for long periods of time without stopping for several hours, and the noise is greater than usual, with a heavy buzz or noise。
Third, refrigeration effects. Normal heating refrigerators, with cooling room temperatures stable at 0-4°c, can stabilize to 18°c in the freeze room, and food products can have normal cooling effects; when heat is abnormal, the internal cooling of the refrigerators slows down, the food in the freezer is susceptible to deterioration, the cold room freezes poorly and the cooling gas is significantly inadequate。
Fourthly, there's no smell and no wiring. If there is a smell of coke or plastic around the refrigerator, the power lines are hot, the plugs are dark, and even if the heat is not particularly severe, the power will be cut off immediately, which is a dangerous signal of the ageing of the circuit and overheating of the metaware。
Only if the above-mentioned aberrations are superimposed and overloaded over a long period of time will it accelerate the aging of the electrical insulation, the damage to the compressor and, in extreme cases, the risk of a fire, which is normal on both sides of the equation, without excessive panic。
Iii. What makes the fridge hot on both sides? Four common causes
In many cases, high temperatures on both sides of the refrigerator, not the machine itself, but the daily usage habits and setting environment, have increased the excretion burden of the refrigerator, resulting in irregular discharges of heat and constant temperature rises, mainly for these common reasons:
1. Over-closed space and insufficient heat-dispersion space
This is the most common problem in the family. In order to clean the kitchen, a number of people shoved the fridge into the closet gap, attached the cabinet on both sides, with a wall around their backs and piled up with miscellaneous items and boxes. Ordinary refrigerators are not embedded in machines, without bottom dispersing designs, and when their surroundings are covered with heat that cannot be distributed in a narrow space, they lead to a sharp rise in the temperature of the shell, which compressors are forced to continue to work at high loads, and when electricity consumption increases, the problem of heat is growing。
2. Condenser ash is heavy and the heat channel is blocked
In the bottom and back of the refrigerator, the condenser distillation grid, with its long-term use, accumulates large amounts of dust, wool and oil pollution, which are like a layer of cotton, wrapped in a radiator road, and the heat cannot be dispersed. Many families do not clean up once in a few years, and the thicker the dust, the lower the heat-dispersion efficiency, the fever in the case, the increased consumption of electricity and the deterioration of the cooling, a series of problems will follow。
3. Inadequate usage, excessive refrigerator load
Freshly boiled meals are placed directly in the refrigerator, with large amounts of hot air pouring into the interior, and compressors need constant operation and cooling; refrigerators are filled with all sorts of stuff, and there is no gap between the food, and the air is not revolving; frequent turn-off of refrigerator doors and the hot air continues to enter will allow compressors to work long hours, heat to increase and heat to become more visible on both sides. The temperature control slot has also been moved to the highest cold slot, and the compressor has been running at full capacity, further exacerbating the heat problem。
4. Age and coldness of door seals and continuous loss of air conditioning
Sealed glue from the refrigerator door is ageing, deformed, cracking, the cooling gas leaks from the door, the temperature within the refrigerator cannot drop, the compressor can only keep working to supplement the cooling, the heat is increasing, and the temperature on both sides of the shell rises. The door can be sewn with an a4 sheet of paper, and if the paper can be easily extracted after closing the door, the seal of the door is no longer valid。
Iv. Solutions that can be operated at home
The refrigerator was found to be hot on both sides of the fridge, without first contacting the maintenance staff, and adjusted to the next steps, the vast majority of heat problems were significantly improved, as well as reduced electricity costs and extended refrigerator life。
First step, standard setting, leaving enough heat space
Ordinary stand-alone refrigerators, with a strict standard for leaving blanks: a minimum of 10 cm from the back of the wall, a 5 - 10 cm gap on each side of the right and the right, and a minimum of 5 - 10 cm gap on each side, and no pile of miscellaneous items on the top to ensure normal circulation of air. Only the manufacturer will be able to embedding in the cupboard if it has a special embedding bottom dispersor, and the ordinary refrigerator will never seal the package. At the same time, refrigerators are to stay away from heat sources such as stoves, ovens, heaters and so forth, and do not put them by the window of the sun, the lower the temperature in the surrounding environment and the lower the heat pressure. The tilt angle should not exceed 45 degrees while moving the refrigerator, avoiding compressor lubricant entering the pipeline and moving to static for 10 minutes to reconnect。
Step two, power outage cleans the dissipated part of the dust
The refrigerator power is removed first, the bottom of the fridge is cleaned with a moustache and dry rags, the dust and furry of the flask on the back, the accumulated dust in the cracks can be cleaned with a vacuum cleaner, direct water is prohibited to wash electrical parts and short circuits are avoided. It is proposed to clean up every three to six months, with more frequent use during the summer, and a marked decrease in the temperature of the shell after the heat spreads。
Step three, correct the wrong usage habits and reduce the burden of running refrigerators
Hot meals must be placed at room temperature before being placed in the refrigerator; refrigerators should not have more than eight cents of their contents, leaving a gap between them to facilitate the cooling cycle; reduced number of openings, with single opening hours being kept as limited as 30 seconds as possible; mechanical temperature control slots, which can be moved to 3-4 in the spring and autumn, do not need to reach the highest cold slot to avoid continuing overloading of compressors。
Step four, check and fix the door seals and solve the cold
The door seals are slightly deformed and can be softened in the shapes of the transformer by electric blowers, press the presses on the box, and cooling will restore the sealing effect; if the glue bars have been hardened, fractured and lost magneticity, the same-style door seals are replaced directly, and the cooling leaks are addressed, the compressor does not have to work continuously and the heat is naturally reduced。
V. Small day maintenance techniques to avoid abnormally hot refrigerators and to extend their useful life
In addition to the above screening methods, simple maintenance on a daily basis can reduce the problem of abnormal fever on both sides from the root causes. First, no heavy refrigerators on either side of the refrigerator should be covered with a heavy decorative sheet to cover the bulk of the case; secondly, when long absences take place, the inside of the refrigerator can be emptied, power shut-downs can be cut off to avoid long run-off; thirdly, regular checks of refrigerator power lines, plugs, ageing, loose and timely replacement of electrical circuits can be carried out to avoid security hazards; fourthly, the first three months of wearout of the new machine, the breakout of the compressor is more frequent, the heater is slightly apparent and normal, and the wearover period tends to stabilize。
Many consider the fevering of both sides of the refrigerator to be a serious failure, either to pay blindly for repairs or to be overly concerned about safety, in fact, it is best to control the temperature of the box by separating normal heat dispersions and abnormal breakdowns and adjusting them to their placement, cleaning and usage habits. Refrigerators are household appliances that operate on an ongoing basis, with reasonable use and maintenance, which not only reduces heat problems, but also reduces electricity consumption and allows machines to use longer periods of time。
The comfort of the use of household electricity often stems from an understanding of the underlying principles, without the need to be anxious by the appearance of heat, or to ignore abnormal failure signals, rational treatment and scientific conservation, in order to better serve daily life。
