Ductwork is used to convey air between the air systems and the terminal equipment and spaces which these air systems serve. Construction Common cross-sectional shapes for ductwork are rectangular, round, and flat oval. Rectangular ductwork is normally used for main ducts and runouts to air devices (air inlets and outlets) that have a rectangular neck. […]
For all cooling tower systems (open and closed-circuit), cooling water is pumped through the water-cooled equipment where it absorbs the heat rejected by the equipment. This water is then circulated to the cooling tower where it is cooled (directly or indirectly) mainly by the evaporation of a portion of the water that is in direct

Because cooling towers are frequently used to reject heat from water-cooled refrigeration equipment, the pipe conveying water from the cooling tower is often referred to as the condenser water supply pipe and the pipe conveying water to the cooling tower is often referred to as the condenser water return pipe. This is the naming convention

Cooling towers are common components of centralized cooling systems. Cooling towers are used either in conjunction with water-cooled chillers for chilled water systems or with plate and frame heat exchangers for water source heat pump systems. Cooling towers are used for HVAC applications in conjunction with water-cooled HVAC equipment to cool water by exposing it

Heat exchangers are commonly used in centralized heating systems and water-source heat pump systems. Heat exchangers are used in HVAC systems where it is necessary to transfer heat from one fluid stream to another without mixing the two fluid streams. Heat exchangers can be used to transfer heat from steam to water, water to water,

Strainers are used to remove any sediment that may be entrained in the fluid stream of the water, brine, or steam system. Strainers are commonly installed at the main system pumps in water or brine systems and also upstream of sensitive components, such as control valves and pressure regulating valves. Strainers used in commercial HVAC

Pressure gauges measure the difference in pressure between two points. It is common for one of these two points to be the atmosphere,22 in which case the measured pressure is based on the reference of atmospheric pressure. This is called gauge pressure. Pressure gauges in commercial HVAC systems are most commonly used to measure the
