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…)
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…)
Liquid to Vapor Propane Evaporators
These evaporators serve a large complex where natural gas is unavailable. The complex needed fuel for boilers for heating and domestic hot water so these evaporators were installed too along with two very large LP tanks to handle the heating needs of the complex. As liquid propane (LP) has a specific weight of .504 (where water is 1) and propane vapor has a specific gravity of 1.5 (where the air is 1) making propane vapor 1.5 times heavier than air. (more…)
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…)
