Working flow chart for air conditioners and refrigerators?
A typical flow chart for air conditioners and refrigerators would include the following main steps: Compressor compresses the refrigerant gas. Refrigerant gas flows through the condenser coils, releasing heat and condensing into a high-pressure liquid. The high-pressure liquid passes through the expansion valve, where it expands and cools down. The cooled liquid flows through the evaporator coils, absorbing heat from the surrounding air. The refrigerant returns to the compressor to start the cycle again.
Why is freon used in refrigerators?
Freon is used in refrigerators because it is an effective refrigerant that can easily absorb and release heat, allowing the refrigerator to cool the air inside and keep food fresh.
What is the role of refrigerant in refrigerators and how does it contribute to the cooling process?
Refrigerant in refrigerators absorbs heat from the inside of the fridge and releases it outside, causing the inside to cool down. It evaporates at low temperatures, absorbing heat in the process, and then condenses back into a liquid to release the heat outside the fridge. This cycle of evaporation and condensation helps maintain a cool temperature inside the refrigerator.
How do refrigerators utilize freon in their cooling process?
Refrigerators use freon as a refrigerant to absorb heat from inside the fridge and release it outside. The freon circulates through a closed system of coils, changing from a gas to a liquid and back again, which helps to keep the inside of the fridge cool.
What is a reaction that gives out a lot of heat?
An example of a reaction that gives out a lot of heat is the combustion of gasoline in engines. This reaction releases a large amount of energy in the form of heat and light.
How Refrigerators and air conditioners are examples of?
heat movers
What are the 2 appliances in the home which operate by using heat transfer?
Two appliances in the home that operate using heat transfer are refrigerators and air conditioners. Refrigerators transfer heat from inside the unit to the outside to keep food cold, while air conditioners transfer heat from inside a room to the outside to cool the air.
What are the appliances that have radiation?
Refrigerators, stoves, and air conditioners transfer heat by radiation. Electric blankets is another example. Toasters would also transfer heat by radiation.
What are some examples of loads?
Examples of loads include household appliances (such as refrigerators, air conditioners), electronic devices (such as computers, TVs), electrical equipment (such as motors, lights), and power tools (such as drills, saws).
How do heat engines use thermal energy and how do refrigerators keep things cold?
Heat engines use thermal energy to generate mechanical work by transferring heat from a high-temperature reservoir to a low-temperature reservoir. Refrigerators keep things cold by using a refrigerant to absorb heat from the inside of the unit and release it outside, thereby maintaining a lower temperature inside.
What are some appliances that operate using heat transfer?
Some appliances that operate using heat transfer include refrigerators (removing heat from inside to cool the contents), ovens (transferring heat to cook food), and air conditioners (removing heat from inside to cool the air).
What are examples of heat engines?
internal and external combustion engine
What has the author J S Arwikar written?
J. S. Arwikar has written: 'Heat engines through theory and examples' -- subject(s): Heat-engines, Problems, exercises
What appliances make use of latent heat of vaporization?
Some common appliances that make use of latent heat of vaporization include air conditioners, refrigerators, and dehumidifiers. These appliances utilize refrigerants that undergo a phase change from liquid to gas, absorbing heat from the surroundings in the process.
What mean thermodinamics?
Thermodynamics is a branch of physics that deals with the relationships between heat, work, and energy. It studies how energy is exchanged and transformed in physical systems. It is fundamental in understanding processes like heat engines, refrigerators, and chemical reactions.

Is whirlpool ac is best?
The performance of refrigerators and air conditioners in the United States is often expressed in terms of the energy efficiency rating (EER), which is the amount of heat removed from the cooled space in Btu's for 1 Wh (watthour) of electricity consumed.
