How is refrigerator an example of a heat mover

Heat movers do not produce any heat but just move from one location to another. The principle of operation of a refrigerator is similar to an air conditioner. It moves the heat energy from inside to outside. There are four basic components in a refrigerator and their functions are as follows:. Compressed liquid refrigerant passes through an expansion valve that reduces the pressure and in turn, the temperature.

The now cold liquid travels through a series of evaporator coils. As it travels through the coils, the liquid evaporates, drawing the heat energy needed for evaporation from the food in the fridge. This process leaves the food cold as the heat has been moved to the refrigerant. No, a refrigerator is a type of heat pump, it takes heat out of the inside and rejects it to a heat exchanger on the back. I don't see how it could be called an insulator. Thermal energy never disappears, but it can be moved from one place to another, which is what a refrigerator does.

If you examine your refrigerator you will be able to observe that there are heat exchange tubes usually on the back which get hot as they pump heat from the interior to the exterior of the refrigerator. That is called "heat energy". Yes, heat exchangers are used.

A refrigerator is a heat pump - it will pump heat from a colder area to a hotter area. I guess this is in the category "thermal energy". Because a refrigerator works by taking heat from the gas inside its tubings and dispersing that heat into the surrounding area, through the grille at the back.

A refrigerator really doesn't make things cold. A refrigerator absorbs heat. The condenser is releasing the accumulated heat into the room.

A refrigerator is designed to pump heat from the inside of the refrigerator to the outside of the refrigerator. Since the refrigerator is inside a room usually a kitchen the heat does not escape from the house that it is in.

If you examine your refrigerator you will find that there is a heat exchange unit, usually in the back although it can be on the sides which gets hot. So if you leave the door open, any cool air that escapes into the room is more than balanced by the heat coming from the heat exchange unit in the back. An air conditioner, in comparison, is designed to pump heat from the inside of a house to the outside of a house.

If, however, you were able to mount your refrigerator inside a window frame which would be extremely difficult and make a reasonably air tight seal, you could then leave the refrigerator door open, and use the refrigerator as an air conditioner. It would be a lot easier to just get an actual air conditioner, however. A heat mover is designed specifically for power plants, aluminum smelters and industrial complexes where low silhouette natural ventilation is the logical choice.

The new heat ventilator is particularly suited for lighter weight where wind and dead loading factors are an important consideration in the overall building design. No, a chick can not go in the refrigerator for 30 minutes because they will die. They need the heat from their mommy or some other heat source, for example an incubator or heat lamp.

The refrigerator takes heat from one place and puts it somewhere else - it is in effect a "heat pump". What you propose can be done, if the heat the refrigerator takes out is taken outside the house. This is exactly what an air conditioner does. It is, in effect, a "refrigerator" especially adapted to cool rooms. Log in. Study now. See Answer. Best Answer. Study guides. Chemistry 20 cards.
