Computer Room Air Conditioner Units | Commercial HVAC
Computer Room Air Conditioner Units - also referred to as CRAC units are essential inside data centers where cooling is necessary for all the computer and electrical equipment most data centers utilize. It is important to keep the equipment cool to prevent overheating...
Chilled Water Storage Tank | Critical Facilities
Chilled Water Storage Tank | Critical Facilities - Data centers use redundant systems for back-ups in case of an emergency. An HVAC chilled water storage tank adds an extra layer of redundancy to the process so if the chilled water plants crash the chilled water...
DX CRAC Unit Condensers | Critical Facility HVAC
DX CRAC Unit Condensers | Critical Facility HVAC - Most data centers do not utilize HVAC DX (Direct Expansion) CRAC units or air conditioning but instead use chilled water systems to provide cooling for the data center. In smaller buildings such as remote telecom...
How Cooling Towers Work | Commercial HVAC
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...
Chilled Water System Efficiency | HVAC Cooling
Chilled Water System Efficiency - Chilled water systems in HVAC are common in large commercial applications utilizing chillers to chill the water, a pumping system to pump the water (water and glycol systems are common), and chilled water coils inside air handlers or...
Chilled Water System Basics | HVAC Cooling
Chilled Water System Basics - Chilled water systems work much the same way as direct expansion systems work. The exception is they use water in the coil rather than refrigerant. Technically speaking, water can be classified as a refrigerant. Chilled Water systems can...
Building Commissioning Benefits | MEP Quality Control
Building Commissioning Benefits - The Building Commissioning Guide defines commissioning as a systemic process of assuring verification and documentation, from the design phase to a minimum of one year after construction that all facility systems perform interactively...
