Spending the summer months without an air conditioning unit is hard to imagine. These machines are specially designed to cool the home and working environments. To suit different needs of individuals, different types of air chillers are available out there. Amongst different air conditioning devices, air-cooled ones are less energy efficient compared to the ones that operate on water. However, unlike water cooled units, the air-cooled chillers are easy to maintain and are less costly. Due to these advantages, most industries, offices, residential, malls, cinemas and businesses prefer using air-cooled chillers.
Operating Procedure of Air-Cooled Chillers
These chillers are specially designed to cool the surrounding air and are perfect for commercial or industrial applications. Termed as air-cooled chillers, it would be completely wrong to assume that they do not use water for cooling. While water is used by the integral system, it does not absorb the heat produced from the closed system of the unit.
The air-cooled chillers include an evaporator. They feature a particular liquid substance, which is used for refrigeration purpose. There are tubes that are filled with water, they surround the items that need to be chilled. While the pressure is increased by the compressor, the apparatus condenses the water vapour, which then connects back to the evaporator.
The cooling process begins in the evaporator - the liquid refrigerant spreads out the cold to tubes that are filled with water. Usually, these pipes surround the area that needs to be cooled. When chilled water is pumped through these pipes, heat is absorbed, thus causing the area to chill.
Applications of Chillers
Air-cooled chillers are most commonly used in laboratories to:
Cool the hot plastic that is stamped, injected or blown extruded in the plastic industry. These chillers are also used to cool down the machines that are mostly used in the manufacturing process.
Sophisticated chillers are also used in high powered electronics machined, such as PET and MRI, and also in new diagnostic tools.
Printing industry also makes good use of chillers. They are helpful in removing the heat that is generated by printing rollers. Chillers are also useful in cooling the paper that comes out from the ink drying ovens. They can also be used for cooling lasers and the power supply source used for powering them.
Irrespective of the type of air cooler you use, ensure that you perform timely servicing to maintain their efficiency.
