Refrigerators

Actually , He invented a refrigerator using an alternate method from the one we are used to.

It only uses a small heat source to provider refrigeration.

Normally, heat moves from a higher temperature to a lower temperature. Devices that use work to move heat are called heat movers. A refrigerator is an example of a heat mover because it takes the heat from inside of the refrigerator and moves it to the outside. The 2nd law of thermodynamics allows this to occur if work is done in the process. A refrigerator does work as it moves the heat from inside the refrigerator to the warmer room.

The pressure in a refrigeration system changes in the compressor, condenser, expansion valve, and evaporator. In the compressor, the pressure increases, while in the condenser, it remains high before decreasing in the expansion valve and evaporator.

James Harrison invented his refrigerator on the Barwon River at Rocky Point in Geelong, Victoria, Australia. His invention was called an ether vapor-compression refrigeration system.

If the refrigerator magnet can't hold a piece of paper against the refrigerator, it may be due to the forces of gravity overcoming the magnetic force produced by the magnet. The weight of the paper pulling it down is greater than the magnetic force trying to hold it up.

Oh, dude, a refrigerator is actually not an insulator. It's like the cool kid in school that keeps things cold by removing heat, not by insulating them. So, while it does help to keep your food fresh and your drinks cold, it's not technically an insulator. But hey, it's still doing its job, so no need to worry about the technicalities, right?

blue ice color can only be made by blue toilet cleaning soluions that have been frozen, food coloring will not freeze throughout the water and create solid blue ice like the toilet cleaner. The chemicals in toilet tank cleaners will. Other colors like rust or yellow ice comes from the same souce and spider ice are a conditions that occurs in a home when the ice maker will draw water for ice and the house water presure is low so the ice maker will draw from the toliet tank usally at night. the home has a toilet fill vlave conected to the cold water line and acts like a straw, the is because the homeowner does not have a code listed or mostly china knockoff fill valve in their toilet that are not anti siphon. The best way to not have an issues is to buy code listed valve, the most popular valve in home depot and lowes is the fluidmaster that also has this same issue when the valve is older than 5 years and the interior gaskets fails. if you are expericeing ice of a differnet color ask any plumber who can remidy with a toilet valve replacment

You should remove the melted ice water in order to keep the cooler colder. As the ice melts, the water will start to warm up and reduce the overall effectiveness of keeping things cold. Drain the water periodically and add more ice as needed to maintain the temperature inside the cooler.

Carl von Linde invented the first methyl ether refrigerator in 1874. In 1876, he developed an ammonia refrigerator. Linde was a German engineer who was born in 1842 and died in 1934.

Mould grows on food because the food is certainly gone bad. Letting the people know that's its gone bad it grows mould and also mould grows because that food may have been lying somewhere for a long time also mould grows when it lies in 1 place after a while there is no space left for the air so then the juice from that certain product goes all over the place in a certain time becoming ''mould''.

A commercial walk-in-box usually has a time-clock type device for the defrost cycle. It is never inside the box. It is usually mounted on top of the box, or near where the compressor is, which is sometimes on the floor level below.

Today's refrigerators use a cold air system to make the refrigerator section cold. In olden days there would be an evaporator in both the freezer section (which the whole freezer compartment actually was) and an evaporator in the refrigerator section. Today's units use one evaporator with a fan in front of it to blow cold air throughout the freezer and into an air vent leading to the refrigerator section. This blowing of cold, really near zero degree , air across the ice cube trays or ice maker bin the result of this is-- if you don't use ice the cubes keep getting smaller due to evaporation,. Usually this takes about 30 days in which the cubes become stale and begin to take on odors of the food that surrounds them. For a cube to be good use them or throw them out after a month because a guest may love onions but not the taste of them in her Johnny Red Rocks.

Probably not. If a refrigerator were in a room so cold that the outside temperature caused the refrigerator to be very cold inside, the thermostat in the refrigerator might not ever cause the device to actually use any energy. For most normal purposes, the refrigerator will be better off in a cooler room simply because the outside atmosphere will not be constantly warming up the fridge from the outside. Think about how much more you need the air conditioning on to keep a room at 70 degrees on a hot day than on a cold one.

A fridge cools things by removing heat energy from the inside of the fridge. This makes it cold inside the fridge. The heat energy that is removed ends up at the back of the fridge. The back of the fridge is often painted black because that makes it a good emitter of heat energy. The fridge may also have a metal cooling grille, also painted black, to help it loose heat to the air. The radiators in our house could be black and it would help them to emit heat into our rooms. In practice people do not want black radiators so they are generally white. the shape of a radiator is designed to give up its heat to air rising up through it.

most likelly is your dischage hose touching whit the discharge pan so the motor makes the discharge pan vibrate and when the motor stops that vibration shakes the dicharge hose making it rattle. in the back botton of the frige look for a hose coming from the inside of your frige and look and see if it's touching the pan on top of the motor and if it is shim it away from the dicharge pan but making sure that the water coming out of the hose will drop inside the pan (this help cool the down the motor and keeps your floor dry) good luck

The volume decreases because the air molecules slow down and pack closer together.

It depends on the model. Some don't have a defrost heater at all, only a timer. On models with a heater, it's either mounted to the evaporator, or actually woven into the evaporator.

You'll need to gain access to the evaporator coils - they're typically at the back of the freezer covered by a panel of some sort. If it's mounted to the coils, then you may be able to replace it yourself.

Also, the heaters rarely go bad - check the defrost termination thermostat as well. If it's near freezing, it should be closed (allowing power to flow to the heater). If it's above freezing, it should be open (cutting power to the heater).

The back of a refrigerator is often painted black to help with heat absorption and dissipation. The black color helps the refrigerator's coils release heat more efficiently, aiding in the cooling process.

The square shape of a refrigerator is practical and space-efficient for storing food and beverages. It allows for more organized storage of items on shelves and in compartments, maximizing the use of the interior space. Additionally, the square shape simplifies the manufacturing process and reduces costs.

Very possible that the start winding of the compressor motor is partially shorted. A grounded winding would cause a breaker to trip, however, a shorted start winding would not produce enough torque to turn the compressor and the run winding would not kick in resulting in the buzzing to stop in about 5 - 10 seconds (start winding timing out). Change the compressor motor or get a new refrigerator, depending on cost factors. Call a professional for compressor replacement unless you want a huge headache. Gary Yingling - Avon Lake, Ohio

Unlikely. People tend to forget that close to the blast the sheer energy of the shockwave, and the heat of the explosion (reaching tens of millions of degrees) will utterly destroy everything in its path. If we look at the Indiana Jones film then it is more likely that he and the fridge he was hiding in would be smashed to bits or vapourised by the blast.

A smaller thickness of lead can be used than other, less dense, materials to absorb most of the of ionising radiation from the blast itself. However, the lead would offer little protection from the shockwave and thermal radiation given off by the blast.

Also, assuming that you did survive the initial blast you would not be able to leave the refrigerator as the environment outside would remain highly radioactive for a long period of time and would be contaminated with fallout material. If you tried to live in the refrigerator long enough for the radiation levels to drop low enough for you to get out of the refrigerator without suffering radiation poisoning, you would not have enough food, water, or air in order to survive that long.

Any fridge - or freezer - is designed to keep its contents cold. It does this by taking heat away from its food compartment and pumping it into a radiator panel fixed to its outside. The radiator - either fixed on to the back of the unit or built into its back panel - must get hot because it receives most of the heat taken from the inside and has to lose it into the surrounding air.

Refrigerator magnets are typically made of a magnetic material like iron or steel that aligns with the magnetic field around it. This alignment allows the magnet to attract to metal surfaces like a refrigerator without having distinct poles like a traditional bar magnet. The magnetism in these materials is more uniform, which is why they don't have clearly defined poles.

The overall average weight of a empty Refrigerator is 200lbs if it is a newer (past 10 years) unit. A side by side or freezer under as well as older units will probably weigh more up to 250 lbs. So it all depends on the size and type and age.

In a fridge, convection works by the movement of cold air sinking and displacing warm air as it rises. The cold air displaces the warm air from the interior of the fridge, absorbing heat in the process. This cycle helps maintain a consistent temperature inside the fridge for food preservation.
