What is the working principle of AC?

What is the working principle of AC?

The basic principle of an air conditioner is a vapor compression cycle to minimize the air temperature with the help of a condenser, compressor, expansion valve, and evaporator. The complete cooling process is a heat transfer between the room air and refrigerant gas.

How AC works step by step?

  1. Step 1: Heat is absorbed by the evaporator coil. The warm air inside your house is drawn in through a vent and blows over the cold evaporator coil.
  2. Step 2: Compressor raises the refrigerant temperature.
  3. Step 3: Heat is transferred outside.
  4. Step 4: Refrigerant gets cold; process repeats.

Which cycle is used in AC?

For this reason, all air conditioners use the same cycle of compression, condensation, expansion, and evaporation in a closed circuit. The same refrigerant is used to move the heat from one area, to cool this area, and to expel this heat in another area.

What is AC cycle?

An air conditioner works using a thermodynamic cycle called the refrigeration cycle. It does this by changing the pressure and state of the refrigerant to absorb or release heat. The refrigerant (aka coolant) absorbs heat from inside of your home and then pumps it outside.

What is Freon formula?

The chemical formula for Freon 12 is – CCI₂F₂. 5.

Why CFC is used in AC?

Chlorofluorocarbon (CFC) is a synthetic substance used in the refrigeration cycle of air conditioning and refrigeration equipment. Chlorofluorocarbons are classified as CFC-11 gases with high global warming potential and the capability of living in our atmosphere for an average of 52 years.

What is a superheat in air conditioning?

Superheat is measured as the difference between the actual temperature of refrigerant vapor at a certain point and the saturation temperature of the refrigerant.

What is evaporator in AC?

The evaporator coil is the component in your AC system that absorbs the heat from the air inside your home. It is often either attached to your furnace or located on the inside of your air handler. It works with a condenser coil to complete the heat exchange process that produces cool air.

What is chiller unit?

A chiller (cooling water circulation device) is a general term for a device that controls the temperature by circulating a liquid such as water or heat medium as a cooling liquid whose temperature was adjusted by the refrigerant cycle.
