Refrigerators

In the yr 1876.reigerator was invented by carl paul gottfried von linde.bt there practicle use in homes starts from 1911.....

If you mean the part of the dishwasher other than the door, it's made of either plastic or stainless steel (whatever the inside is made of, that's the same as the outside). If you mean the door, either painted steel or stainless steel.

The condenser is the component of a refrigeration system that changes high-pressure vapor into high-pressure liquid by transferring heat to the surrounding environment. This process involves the conversion of refrigerant from a gas to a liquid state by releasing heat to the outside air or water.

Assuming they've all been in there long enough to equilibrate, and assuming you haven't put them in some "special" location that's colder or warmer than average (the shelves in the door, for example, are often slightly warmer than the main shelves), they will all be the same temperature.

William Cullen did not invent the refrigerator. The first practical refrigerator was invented by Oliver Evans in 1805. Refrigerators were developed to preserve food and extend its shelf life by keeping it cool.

A refrigerator is not on all the time. It is controlled by a thermostat that keeps it at a certain temperature. To answer this question the total number of hours the refrigerator was actually running would have to be recorded. Knowing this information and the voltage at which the refrigerator operates a calculation could be made.

thermal energy never disappears but, it can be moved from one place to another which what a refrigerator does. on the back of a refrigerator there are heat exchange tubes which get hot as they pump heat from the interior to the exterior of the refrigerator.

No.. otherwise water would turn to ice when in a fridge.. i don't think that happens too often ;) My fridge thermometer instruction sheet recommended 44 deg. F as the optimum temp for lower shelves.

Food does not go bad anymore, meaning food can be stored, meaning that more food could be made because more would be wasted, meaning agriculture benefited from the fridge, and so did companies that make the fridge. +1 point for capitalism.

Kilograms.

liters is mot a mass unit but a volume unit so that cannot come into discussion at all.

The only difference between milligrams, grams and kilograms is that 1000 milligrams makes 1 gram and 1000 grams makes 1 kilogram. so you can of course measure the weight of a refrigerator in milligrams but you would have a value in the tens of millions.

In basic theory yes it would get colder by installing a lower temp thermostat.

However the common household refrigerator was not designed for that application,..most household Units set at the lowest temp can cool down to about 35*F in the refrigerator section,and 20-28*F in the freezer section... putting in a lower temp thermostat may cause the unit to run constantly as it tries to achieve the lower temp settings and If your unit runs constantly your electric bill will skyrocket and I would estimate that within 3-7 days of constant running you would either burn out a thermal overload or the compressor unit...

Refrigerators are cold because they use a refrigeration system that removes heat from the interior to lower the temperature. The refrigeration system consists of a compressor, condenser, expansion valve, and evaporator working together to circulate refrigerant, absorbing heat and cooling down the interior of the refrigerator.

It is not recommended to place a refrigerator next to a hot water heater. The heat from the water heater can affect the refrigerator's cooling system, causing it to work harder and potentially reducing its efficiency. It is best to keep appliances like refrigerators away from sources of heat to ensure they operate effectively.

A whole house filter is normally a terrible waste of money as why filter water to be used for flushing toilets?

Ans 2 - The first answer does not have relevance to the question.

Your refrigerator has it's own inline filter. -It appears that it's time to change it. -This is generally quite simple and the filter can be bought at any appliance parts store. Be sure to have the make, model and ser # when buying this (or any appliance parts )

The outer surface of a fridge is typically white and shiny to reflect light and heat, which helps keep the fridge cooler by preventing heat absorption. The white color also helps to easily spot dirt or stains for cleaning.

well it depends on the magnet is it strong or not

Subcooling increases the efficiency of a vapor compression refrigeration system by ensuring that the refrigerant entering the expansion valve is in the liquid state and at a lower temperature than the saturation temperature, reducing the amount of flash gas that would otherwise form. This results in increased cooling capacity and improved COP (Coefficient of Performance) of the system.

Fruit left out of the refrigerator for a few days would undergo a physical change. This is because the fruit would start to rot, change color, and possibly develop mold, but the chemical composition of the fruit itself does not change. The changes are primarily due to environmental factors like exposure to air, moisture, and microorganisms.

In practical applications, vapor-compression refrigeration systems are the most commonly used refrigeration systems, and each system employs a compressor. In a basic vapor compression refrigeration cycle as shown in Figure 3.28, four major thermal processes take place as follows:

• evaporation,

• compression,

• condensation, and

• expansion.

A three-stage centrifugal compressor uses multiple sets of impellers to progressively increase the pressure of the gas being compressed. Each stage consists of a stationary diffuser and a rotating impeller that accelerates the gas outward, increasing its velocity and pressure. The gas passes through each stage sequentially, with the pressure rising after each impeller set, allowing for efficient compression of the gas.

This is difficult to answer, because it depends on many factors -- how often the door is opened, the ambient temperature, how much is in the refrigerator, and whether new items were recently added to the refrigerator and need to be cooled down.

Most frost-free refrigerators have a timer that runs them for 6 hours, then defrosts them for 30-35 minutes. This means, at the the upper limit a refrigerator might run 24 hours out of every 26 hours, or an equivalent of 22.1 hours per day. (The timer only runs when the compressor runs on energy saving models, so if the compressor motor doesn't run continuously, the intervals between defrost periods will be longer than 6 hours.)

Once the contents are cooled down, a modern refrigerator in good condition might be expected to run 27% to 37% of the time at an ambient temperature of 70°F, i.e., 6.5 to 8.9 hours per day, and 45% to 61% of the time at an ambient temperature of 90°°F, i.e., 10.8 to 14.6 hours per day.

The only practical way to determine how long a refrigerator runs each day is to connect a run-time counter to the compressor motor circuit and operate the refrigerator for one to two weeks, or longer, then read the total run time from the counter and calculate the average number of hours the refrigerator ran each day.

The ice compartment is typically placed at the upper portion of a refrigerator because cold air is denser and tends to sink, making it more efficient to maintain a consistent temperature for ice production. Placing it at the top allows the cold air to naturally circulate down to the rest of the refrigerator. Additionally, placing the ice compartment at the top makes it more accessible and easier to reach for users.

In a Frigidaire washer, bleach should be added to the bleach dispenser, typically located in the detergent drawer. Refer to your washer's manual for specific instructions on how to add bleach to your model.

Refrigerators typically contain a refrigerant gas like hydrofluorocarbons (HFCs) or chlorofluorocarbons (CFCs). These gases undergo a cycle of compression and expansion to remove heat from inside the fridge.

The energy for a refrigerator to transfer heat from inside to outside is provided by the compressor unit, which compresses and circulates the refrigerant throughout the system. As the refrigerant absorbs heat from the interior of the refrigerator, it is compressed and released outside, dissipating the heat into the surrounding environment. This process allows the refrigerator to maintain a cool temperature inside.
