Chillers and HVAC Systems
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 in the market, but none more popular than an air chiller. It works by cooling down a liquid such as water. It has certain parts, like a compressor, condenser, and an 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 off at the device compressor point. 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 gets cooled down considerably while in there. After all the gas has been converted into a cool liquid, it flows into the thermal expansion valve. At this stage, the amount of refrigerant that goes into the evaporator can be monitored. When the refrigerant goes through the evaporator, it takes most of the heat, which causes it to boil off and thereby converting into a vapor. Water is then pumped into the evaporator, which gets heated by the refrigerant. This is usually followed by the refrigerant being channeled into the compressor once again, where it becomes a hot compressed gas from the initial stages. The process repeats.
Air conditioning systems have chillers in them. They can cool off the air as water would have. The steps of how a chiller works are always ongoing. The chiller that is ideal for an air conditioning system can be anywhere from 15 to 1500 tons. It can make water get to freezing temperatures.
Chillers have a number of industrial applications. Chillers have long been implemented in the cooling off of industrial heat waste, a process that can also be used to cool off the surrounding air. 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.
It is clear that chillers have application in diverse fields. 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 the nature of certain components of the chiller. It is important to think of hoe energy efficient it is. Inspect also the ease of its operation. It should also be easy to do maintenance duties on it. The device has to come with a reasonable warranty for what the manufacturer is charging for it.
