Difference Between Refrigeration and Air Conditioning

In refrigeration, there is a transfer of thermal energy from a place at a cold temperature to a place at a higher temperature. In AC, thermal energy is taken away to keep the air at a cool temperature. ... The key difference between refrigeration and air conditioning lies in the supply point.

What is refrigeration and air conditioning?

Refrigeration is the process of lowering the temperature of a substance below that of its surroundings and includes production of chilled water for air conditioning or process applications.

Can we use refrigerator as AC?

Use an Air Conditioner

This is because refrigeration is not a perfectly efficient process. More heat enters the room through the exhaust vent than is extracted from the inside of the refrigerator. ... Alternatively, you can use a refrigerator to cool a room if the heat vents for the fridge are in a different room.

What is meant by refrigerating effect?

Refrigeration effect is the amount of heat that each pound of refrigerant retains from the refrigerated space to deliver helpful cooling. In the gas cycle, the refrigeration effect is equivalent to the result of the particular warmth of the gas and the ascent in temperature of the gas in the low temperature side.

What is the importance of refrigeration and air conditioning?

The refrigeration process removes heat from an enclosed space to reduce and maintain the temperature for the contents of that space. While air conditioning regulates the air in a large building, refrigeration solely cools and is generally used in a smaller space.

Which gas in AC is best?

The most common HFC used in air conditioners is R-410A. This refrigerant is better than R-22 in terms of “Ozone Depletion” potential and energy efficiency, but it still causes global warming. A few more HFCs that are commonly used are: R-32 in Air Conditioners and R-134A in refrigerators.

Can we make air conditioner at home?

You just need a fan and two plastic soda bottles to make this air conditioner. Modify the bottles by cutting off the end and punching holes in the sides. Then strap them to the back of the fan and fill the bottles with ice. Voila!

What is the basic principle of refrigeration?

The absorption of the amount of heat necessary for the change of state from a liquid to a vapor by evaporation, and the release of that amount of heat necessary for the change of state from a vapor back to the liquid by condensation are the main principles of the refrigeration process, or cycle.

What are the four stages of refrigeration?

The refrigeration cycle contains four major components: the compressor, condenser, expansion device, and evaporator. Refrigerant remains piped between these four components and is contained in the refrigerant loop.

What is unit of refrigeration?

The standard unit of refrigeration is ton refrigeration or simply ton denoted by TR. It is. equivalent to the rate of heat transfer needed to produce 1 ton (2000 lbs) of ice at 32 0F. from water at 32 0F in one day, i.e., 24 hours.
