2008 ASHRAE Handbook - Heating, Ventilating, and by American Society of Heating

By American Society of Heating

The 2008 ASHRAE instruction manual - HVAC structures and gear discusses numerous platforms and the gear (components or assemblies) that include them, and describes positive factors and alterations. this data is helping approach designers and operators in opting for and utilizing gear. it truly is divided into seven sections:

  • Air-Conditioning and Heating structures
  • Air-Handling apparatus and parts
  • Heating gear and parts
  • Cooling gear and parts
  • General parts
  • Packaged, Unitary and Split-System apparatus
  • General
    This identify has been lately up-to-date with 221 Digitized Graphs and a pair of Interactive Tables masking potency, radiation warmth flux, functionality, warmth loss and lots of different necessary subject matters.

    Primary air or recirculated room air. Relatively small lowpressure systems place reheat coils in the ductwork at each zone. More complex designs include high-pressure primary distribution ducts to reduce their size and cost, and pressure reduction devices to maintain a constant volume for each reheat zone. The system uses conditioned air from a central unit, generally at a fixed cold-air temperature that is low enough to meet the maximum cooling load. Thus, all supply air is always cooled the maximum amount, regardless of the current load.

    This system (Figure 11), frequently used as a retrofit to an antiquated dual-duct, single-fan application during the 1980s and 1990s, uses a single supply fan sized for the peak cooling load or the coincident peak of the hot and cold decks. Fan control is from two static-pressure controllers, one located in the hot deck and the other in the cold deck. The duct requiring the highest pressure governs the airflow by signaling the supply fan VFD speed control. An alternative is to add discharge supply air duct damper control to both the cold and hot ducts to vary flow while the supply fan operates up and down its fan curve.

    Steam injection is a constant dry-bulb process (Figure 7). As the steam injected becomes superheated, the leaving dry-bulb temperature increases. If live steam is injected into the airstream, the boiler water treatment chemical must be nontoxic to occupants and nondamaging to building interior and furnishings. 6 Fig. 6 2008 ASHRAE Handbook—HVAC Systems and Equipment Direct Spray of Recirculated Water Fig. 6 Fig. 7 Direct Spray Humidification Fig. 8 Chemical Humidification Fig. 8 Chemical Dehumidification Steam Injection Humidification AIR-HANDLING UNIT COMPONENTS Fig.
