Refrigerators

A full freezer maintains lower temperatures more effectively than an empty one because the items inside act as thermal mass, helping to retain coldness. This reduces the workload on the compressor, leading to more efficient cooling and potentially lower energy consumption.

The shaking could be caused by the refrigerant flowing through the system, which creates vibrations when the compressor shuts off. It could also be due to unbalanced internal components or the evaporator fan motor. If the shaking is excessive or accompanied by unusual noises, it's best to have a technician inspect the refrigerator.

Refrigerant absorbs heat from the air inside a refrigerator or air conditioner, causing it to change from a liquid to a gas. As it releases the absorbed heat outside, it condenses back into a liquid, and the cycle continues. This continuous process of absorbing and releasing heat allows the refrigerant to cool the air inside the appliance.

Balancing a refrigeration system involves adjusting various components such as the expansion valve, evaporator, and condenser to ensure proper operation and efficiency. This process helps optimize the system's performance by ensuring that each component is working at its designed capacity and that the system is thermally balanced.

This is a matter of melting and freezing. When you touch the tray, the warmth from your finger quickly melts a bit of a ice and creates a thin layer of water between the tray and your finger. Since the tray is so cold, it quickly freezes that thing layer of water forming an icy bond between your finger and the tray.

Old fridges typically use chlorofluorocarbons (CFCs) as the refrigerant gas. These gases have been phased out due to their harmful effects on the ozone layer.

A refrigerator uses a refrigeration system to remove heat from the interior, keeping the inside cool. It does this by circulating a refrigerant through a series of coils where it absorbs heat from inside the fridge and releases it outside. The insulation in the walls of the refrigerator helps to maintain the cool temperature by trapping the cold air inside.

If it is in working order with everything pristine (chrome, paint etc).... restored like new.... depending on the model $500 to $2000 if the buyer can show it off...

If it is rusty or beat up... if the buyer has to pull it out of your basement and restore it himself.... $100 to $300

Obviously some are worth more than others.

Some Philcos are worth way more!

The three basic laws of refrigeration are: 1) The law of conservation of energy, which states that energy cannot be created or destroyed, only transferred or converted. 2) The first law of thermodynamics, which states that energy is conserved in a system and can be neither created nor destroyed. 3) The second law of thermodynamics, which states that heat will naturally flow from a high-temperature region to a low-temperature region.

Most refrigerators use a capillary tube as the refrigerant metering device. It is a simple and cost-effective way to regulate the flow of refrigerant into the evaporator coil.

When you close the fridge door, a mechanism called a door switch is activated, which is designed to turn off the light to save energy and prevent the temperature inside the fridge from rising. This helps to maintain the cool environment needed to keep the food fresh.

the cells in the celery lose water through evaporation, causing the celery to become dehydrated and limp. Celery has a high water content, so when it is exposed to air in the refrigerator, it can lose moisture quickly, leading to wilting.

Ice water will cool a soda faster than the fridge. This is because the ice water can transfer heat more quickly to the soda due to the direct contact and the greater temperature difference between the two. The fridge cools the soda more slowly as it relies on the surrounding air to cool down the drink.

In the 1930' non-toxic, non-flammable synthetic refrigerants such as Freon-12 were introduced. However, R-12 damaged the ozone layer, causing governments to issue a ban on its use in new refrigerators in 1994. The less harmful replacement, R-134a has been in common use since 1990.

The cooling unit in the refrigerator is typically located at the top. As a result, cold air is generated at the top and then circulates down to the bottom. This can lead to the bottom being warmer as the cool air sinks and the warm air rises. Regularly cleaning the coils at the back can help with air circulation and temperature regulation.

Refrigerants remove heat in a refrigerator by changing phases within the coils. They will absorb or release heat through evaporation or condensation. The compressor and expansion valve facilitate the pressure changes.

Cloudy white ice in a freezer is often caused by trapped air bubbles or impurities in the water that form as the ice freezes. These air bubbles and impurities don't have a chance to escape during the freezing process, resulting in a cloudy appearance. Using distilled water or allowing water to sit and degas before freezing can help produce clearer ice cubes.

Jacob Perkins did not invent the refrigerator, he is known for inventing a more efficient refrigeration system in 1834. The first mechanical refrigeration system was patented by Oliver Evans in 1805, but it was not widely adopted at the time.

When the door of a refrigerator is opened, the temperature inside the refrigerator typically increases. This is because warm air from the surrounding environment enters the refrigerator, causing the internal temperature to rise. The refrigerator's compressor then works to cool the air back down to the set temperature once the door is closed.

No, placing an open refrigerator in a closed system would not make it get colder. The cooling effect of a refrigerator is achieved by removing heat from the inside and releasing it outside. In a closed system, the removed heat would simply accumulate, leading to the refrigerator eventually reaching thermal equilibrium with its surroundings.

The newer refrigerant in use today is typically HFC (Hydrofluorocarbon) refrigerants such as R-410A or R-134a. These refrigerants have been introduced as alternatives to phased-out HCFCs and CFCs due to their lower impact on ozone depletion and global warming.

The pressure on the low pressure side of a system is determined by factors such as the volume of the system, the amount of gas present, and the temperature. A decrease in volume or an increase in temperature can lead to an increase in pressure. Conversely, an increase in volume or a decrease in temperature can lead to a decrease in pressure on the low pressure side.

freezers and fridges are based on evaporation of coolant liquid, in a cooling cycle. To evaporate heat is drawn from the environment. However if your environment is cold, evaporation will be harder, and the fridge/freezer won't work as well.

To increase the coefficient of performance (COP) of a Carnot refrigerator or heat pump, you can enhance the efficiency of the system by reducing the temperature difference between the heat source and sink, improving the insulation of the system to minimize heat losses, and utilizing more efficient components such as compressors or heat exchangers. Additionally, optimizing the working fluid and operating conditions can also help improve the overall performance of the system.

Because energy can't be taken away (except with fusion of atoms larger then iron, which is impractical for a refrigerator). This means the energy, the heat, has to be moved to another place for one place become lower in temperature.
