Actuators for Chilled Water Valve | DDC Commercial Systems

Actuators for Chilled Water Valve – These chilled water actuators control the flow rate for a chilled water system in a data center. There are various sequence of operations for chilled water systems and the sequence of operation is usually always different from one chiller plant to another chiller plant. It depends on the components in […]

Air Management in Hydronic Piping Loops

Air Management in Hydronic Piping Loops This is a secondary chilled water pump in a large pump room designated for pumps and piping in a data center. After a few minor tweaks and corrections these pumps all operated flawlessly. There was very little issues with the secondary pump start-ups unlike the primary pumps where cavitation […]

Cooling Tower Fan | Commercial HVAC

This is a 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 […]

Large Condenser Pump for a Chilled Water System

Large Condenser Pump for a Chilled Water System This large HVAC condenser pump serves a new chiller located in a data center. This pump pumps condenser water through the condenser chiller barrel and to a cooling to reject the heat absorbed in the chillers evaporator barrel. The pump works to move the water from the […]

DX CRAC Unit Condensers | Critical Facility HVAC

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 buildings DX air […]

Chilled Water System Basics | HVAC Cooling

Chilled Water System Basics Chilled Water System Basics – Chilled water systems work much the same way as direct expansion systems work except they used chilled water in the coil rather than refrigerant (Technically speaking, water can be classified as a refrigerant). Chilled Water systems can be rather complex and many chilled water systems are […]

Trane Chilled Water Systems – Multi-Zone Air Conditioning Systems

This Trane HVAC chiller serves four different apartments. Chilled water systems offer a great way for multi-zone air conditioning. From small apartment buildings to large commercial buildings chilled water systems can serve multi-zone air conditioning systems. From one air conditioning zone to hundred the only limitation is the size of the chiller. If the air […]

Plate Heat Exchanger and Free Cooling

Plate Heat Exchanger and Free Cooling 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. Plate heat exchangers are used in marine applications, industrial processes including chemical processing systems, food processing, and many HVAC applications including […]
