How Effective Chillers are in Air Conditioning
A chiller is used to cool temperatures, and is classified as an HVAC equipment. There are many kinds of chillers, the most common being the air chillers. It works by cooling down a liquid such as water. The device has several components, including a compressor, condenser, and the evaporator, as well as a thermal expansion valve. It is a common air conditioning application, as well as in industrial settings.
A chiller works through a certain process. It starts its cooling process at the compressor unit. The compressor forces a refrigerant into a hot compressed gas. The refrigerant gets pumped into the condenser, which then condenses the gas into a liquid when it is cooled off by a fan. The chiller tends to lose almost all of its heat at this stage. Once all the gas has turned into a cool liquid it moves into the thermal expansion valve. At this stage, the amount of refrigerant that goes into the evaporator can be monitored. The refrigerant then collects the heat in the evaporator, which manages to turn into gas. Water is then pumped into the evaporator, which gets heated by the refrigerant. After this, the refrigerant goes into the compressor again, where it is turned into the previous hot compressed gas from the earlier stages, and s then directed into the condenser. The steps are repeated all over again.
Chillers can be found in air conditioning systems. They function in the system as chilled water would, to cool off the air. This is a constantly repetitive process. In an air conditioning system, a chiller that would run the whole systems effectively can vary in size, from 15 to about 1500 tons. It can make water get to freezing temperatures.
Chillers can be used in industrial settings in a number of ways. Chillers are used to cool heat waste produced in a manufacturing process, which is then applied in the cooling off of the air. High intensity lasers also produce enough heat waste that only a chiller can handle. Chillers are needed when complex cutting processes in industries result in some hot pieces of materials that need to be cooled down, or when an MRI machine needs to have its working temperatures monitored and controlled.
There is enough examples of the usefulness of chillers in many areas. In your selection of a chiller, you need to consider several points. You need to look at the kind of material used in its construction. You also need to look at specific parts of the machine. You have to look into the kind of energy efficiency on offer. Choose a machine that is easy to operate. Repairing it, if need be, should not cause more stress or damage. Check also the kind of warranty the manufacturer offers.
