Glycol is like antifreeze and is used in chilled water piping loops to prevent freezing. Everyone knows when the pipes freeze they also break and start leaking. Having antifreeze in a chilled water loop is important to prevent freezing. (more…)
Critical Facilities and Make-up Water. Data Centers a categorized by tier levels and everything in the data centers infrastructure is checked and classified so that any particular data center can achieve a certain tier level based on the infrastructure in the data center. (more…)
About Chilled Water Systems HVAC Hydronics - Chilled water systems are mainly used in large commercial HVAC air conditioning systems and industrial cooling applications although there are some residential and light commercial HVAC chilled water systems in use. Chilled water systems are popular because they use water as a refrigerant. Water is far less expensive than refrigerants. This makes them cost-effective, especially in commercial HVAC air conditioning applications. (more…)
This is an HVAC chilled water system cooling tower fan for a large chilled water system. Four large cooling towers for two chiller plants in a data center. Data center cooling systems generally are redundant not only for emergency situations but also for maintenance. The cooling tower fan typically has vibration switches installed in the fan assembly to shut the fan off in the event of too much vibration. (more…)
Cooling Tower Evaporation Cools Water | HVAC Technical - Cooling towers use the process of evaporation to cool or removes heat from the condenser water that was transferred to the water in the chiller condenser barrel. The heat is absorbed in the load in this case in a data center on a data center floor. The servers and electrical equipment produce a massive amount of sensible heat.
The heat is absorbed by computer room air conditioners or computer room air handlers. These systems, computer room air handlers, and air conditioners have chilled water coils. The chilled water originates at the chiller into the primary loop. The water circulates through the primary loop and makes its way into the secondary loops. (more…)
Air Source Chillers provide cool water for a hydronic piping system
How Hydronics Works | HVAC Technical for Consumers - Hydronics refers to using water and chilled water, steam boilers and hot water boilers, and other methods of transferring heat using water.
A boiler or chiller is used to heat or cool the water and then the water is transferred through the hydronic piping loops to heat exchangers such as coils or baseboards where heat is transferred from the water to the air for heating and from the air to the water for cooling to provide comfort for people or a process.
Hydronics is very popular in commercial and industrial HVAC applications for heating and cooling occupants in large buildings and providing heating and cooling for equipment and machines including computers and servers. Basically in a nutshell Hydronics uses water to move heat from one place to another.
How Cooling Towers Work - Cooling towers use evaporation cooling to cool condenser water from a chiller. Water is pumped to the top of the cooling tower, where the water flows down some flow plates to the cooling tower basin. As the water is flowing down the flow plates air is pulled through the plates and over the water where it releases heat through evaporation. (more…)
Plate Heat Exchanger and Free Cooling - This plate heat exchanger is used in a data center for a chilled water system and is a chilled water economizer. Heat exchangers are used in marine applications, industrial processes including chemical processing systems, food processing, and many HVAC applications including chilled water applications, hot water applications, and economizer applications.
