How Effective Chillers are in Air Conditioning
A chiller is a type of HVAC equipment that is applied in the provision of cold temperatures, or for cooling purposes. There are many kinds of chillers, the most common being the air chillers. It commonly refers to the device that will cool down a liquid, such as water. It has certain parts, like a compressor, condenser, and an evaporator, as well as a thermal expansion valve. You will see some chillers being used to cool buildings.
A chiller works through a certain process. The system kicks off at the compressor unit. The compressor pumps a refrigerant inside, which started off the cooling process as 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. At this stage in the cycle, a lot of the heat is blown out of the chiller. After all the gas has been converted into a cool liquid, it flows into the thermal expansion valve. At this stage, there has to be a strict control on how much refrigerant can be allowed into the evaporator. As the refrigerant passes through the evaporator, it takes with it most of the heat, which makes it boil into a vapor. Water is introduced into the evaporator, which the refrigerant heats up. 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. The steps of how a chiller works are always ongoing. The size of an adequate chiller ranges from 15 all the way to 1500 tons. It can make water get to freezing temperatures.
There are a few places a chiller can be used in an industrial situation. when there is industrial heat waste produced, chillers can be used to cool it off, then make enough cold air for the environment. Chillers are effective to heat dissipators when it comes to high-intensity laser usage. They are also used when cooling workpieces that are being cut by machine tools, or to properly control temperatures inside an MRI machine.
There is enough examples of the usefulness of chillers in many areas. While out shopping for one, there are key areas that you must adequately cover. There is need to inspect the kind of material that was used in making it. You also need to look at the nature of certain components of the chiller. The level of energy efficiency of the system has to be considered. Choose a machine that is easy to operate. It should also be easy to do maintenance duties on it. Check also the kind of warranty the manufacturer offers.
