What is the difference between an air conditioner and a chiller?

Answer 1

AC is ----- which can convert air to hot as well as cold or we can say which maintains the temp. i.e. if it is hot it can cool the room n if it is cold outside u can warm the room.

A Chiller is a machine that produces chilled water (usually mixed with ~20% glycol and corrosion inhibitors) which is used to cool and dehumidify air in commercial and industrial facilities .t]

Use in air conditioning

In air conditioning systems, chilled water is distributed to air handling units as a refrigerant. These air handling units provide air conditioning to the building by running the incomming warm air through the coil of chilled water, transferring the heat from the air to the chilled water, thus, cooling the air.

A typical chiller for air conditioning applications is rated between 15 to 1000 tons (180,000 to 12,000,000 BTU/h or 53 to 3,500 kW) in cooling power.


Use in industry

In their industrial application, cooled refrigerant from the chiller is pumped through process or laboratory equipment.

Industrial chillers are used for controlled cooling of products, mechanisms and factory machinery in a wide range of industries. They are often used in injection and blow molding, metal working cutting oils, welding equipment, die-casting and machine tooling, chemical processing, pharmaceutical formulation, food and beverage processing, vacuum systems, X-ray diffraction, power supplies and power generation stations, analytical equipment, semiconductors, compressed air and gas cooling. They are also used to cool high-heat specialized items such as MRI machines and lasers.


Technology

There are basically four different types of chillers: Reciprocating, centrifugal, or screw-driven chillers are mechanical machines that can be powered by electric motors, steam, or gas turbines. Absorption chillers are powered by a heat source (such as steam or hot water). They have very low electrical power requirements - very rarely above 15 kW combined consumption for both the solution pump and the refrigerant pump.

Chillers can be air-cooled or water-cooled. Water-cooled chillers incorporate the use of cooling towers which improve heat rejection more efficiently at the condenser than air-cooled chillers.

Answer 3

A chiller is the bit of the air-conditioner that actually does the chilling. The other bits of the air conditioner are concerned with moving air around and maybe heating the air.

Answer 4

An air conditioner circulates the air in a room and cools it by removing the heat from the air (using a compressor and some type of gas such as Freon).

A chiller is basically a fan blowing across something wet such as a mist of water, a trickle of water from tubes, water running through a closed system, etc. to cool the air by evaporation. It only really works well in areas of low relative humidity.

Answer 5

Inside the tube of ac evaporator, the refirigerant temperature can reached below zero degree Celcius.
inside Chiller air handling unit (AHU) there is chilled water, which temperature never reached zero degree otherwise the water will be iced.
Therefore ac absorbed heat more than chiller for the same size of area, or ac cooling capacity per square area is higher than chiller.

Answer 6

What do you mean by chiller? Like a refrigerator? The concept is exactly the same, just on a different scale.

ac is usually for a smaller area and a chiller is for a large building like a hospital
