This guide discusses a variety of structures and the apparatus (components or assemblies) they include, and describes gains and alterations. this knowledge is helping process designers and operators in making a choice on and utilizing apparatus. This variation features a new bankruptcy 18, Variable-Refrigerant-Flow platforms, which describes those structures, their parts, and appropriate criteria intimately, and features a procedure layout instance and critical counsel on charges, controls, and protection. This guide is a reference for engineers operating in HVAC&R and for execs in allied fields. ASHRAE, based in 1894, is a world association of a few 50,000 people. ASHRAE fulfills its undertaking of advancing heating, air flow, air-con, and refrigeration to serve humanity and advertise a sustainable global via examine, criteria writing, publishing, and carrying on with schooling.

Sample text

For single high-rise central plants, intermediate-floor locations that are closer to the load may allow pumping equipment to operate at a lower pressure. A life-cycle cost analysis (LCCA) should include differences in plant location to identify the most attractive plant sustainability options during the planning stage. The LCCA should consider equipment maintenance access, repair, and replacement during the life of the plant, as determined in the owner’s criteria. If not identified, an engineer should suggest to the owner or client that maintenance criteria be included as a component in developing the LCCA (see the section on Operations and Maintenance Considerations).

For example, a dual-duct system is more expensive because it requires essentially twice the amount of material for ducts as that of a comparable single-duct system. Systems requiring extensive use of terminal units are also comparatively expensive. The operating cost depends on the system selected, the designer’s skill in selecting and correctly sizing components, efficiency of the duct design, and effect of building design and type on the operation. Because an all-air system separates the air-handling equipment from occupied space, maintenance on major components in a central Fig.

Central fan rooms are more common in large buildings, where maintenance is isolated from the conditioned space. Reasons a design engineer may consider a central air-handling unit, or bank of central air-handling units, include the following: • Fewer total pieces of equipment to maintain. • Maintenance is concentrated at one location. • Filtration is easily enhanced. • Energy recovery opportunities may be more practical. • Vibration and noise control, seismic bracing, outdoor air intakes, economizers, filtration, humidification, and similar auxiliary factors may be handled more simply when equipment is centralized.
