    Fans

    Greenheck

    Understanding Fan System Effects

    The air moving industry uses a common term to describe certain inlet and outlet conditions that adversely affect fan performance. The term used is "system effect". Perhaps the term should be "fan installation effect", because system effect results from the difference in how the fan was tested, compared to how it is installed. To minimize system effects, air must enter or leave a fan uniformly.

    Filtration

    Vortisand

    On-Demand Webinar: Choosing the Right Water Filtration System Will Maximize Your Cooling Tower Efficiencies

    Water from cooling towers attracts and absorbs airborne contaminants on a continuous basis. Typically, 85% of suspended solids in cooling water and hot water loops are smaller than 5 microns. Scientific studies have shown that these fine particles (5 microns and less) are the adherent contaminants fouling the water loop and cooling system.

    Manufacturing facilities are routinely reviewing their system's water quality and treatment levels to prevent early and rapid corrosion, scale and biological growth; leading to unplanned facility maintenance and/or shutdown. Listen to our HVAC cooling expert as he shares his cooling tower knowledge and expertise with ASHRAE.

    Superheat and Subcooled Levels for Water Source Heat Pumps

    This paper evaluates and analyzes the superheat and subcooled levels for water source heat pumps. As per the non-ideal refrigeration cycle, each cycle has a certain amount of superheat in the suction line and a certain amount of subcooled liquid in the liquid line. By evaluating the level of measured superheat and subcooled levels for a known correctly charged system, we can document and publish the results for internal and external use. By connecting temperature gauges to the suction and liquid lines of a system, the superheat and subcooled levels of the system can be found relatively quickly. Charge can be declared to be correct if the values of the superheat and subcooled levels match those of the lab tested values.
