Local factors include energysource availability (presen

38、t and projected) and price; climate;socioeconomic circumstances; and availability of installation andmaintenance skills. Application factors include housing type, con-struction characteristics, and building codes. As a result, many dif-ferent systems are selected to provide combinations of heating,c

39、ooling, humidification, dehumidification, ventilation, and air filter-ing. This chapter emphasizes the more common systems for spaceconditioning of both single-family (i.e., traditional site-built andmodular or manufactured homes) and multifamily residences. Low-rise multifamily buildings generally

40、follow single-family practicebecause constraints favor compact designs; HVAC systems in high-rise apartment, condominium, and dormitory buildings are often ofcommercial types similar to those used in hotels. Retrofit and remod-eling construction also adopt the same systems as those for new con-struc

41、tion, but site-specific circumstances may call for uniquedesigns.SYSTEMSCommon residential systems are listed in Table 1. Three gener-ally recognized groups are central forced air, central hydronic, andzoned systems. System selection and design involve such key deci-sions as (1) source(s) of energy,

42、 (2) means of distribution and deliv-ery, and (3) terminal device(s).Climate determines the services needed. Heating and coolingare generally required. Air cleaning, by filtration or electrostaticdevices, is present in most systems. Humidification, which is com-monly added to all but the most basic

43、systems, is provided in heat-ing systems for thermal comfort (as defined in ASHRAE Standard55), health, and reduction of static electricity discharges. Coolingsystems usually dehumidify air as well as lowering its temperature.Typical forced-air residential installations are shown in Figures 1and 2.F

44、igure 1 shows a gas furnace, split-system air conditioner,humidifier, and air filter. Air from the space enters the equipmentthrough a return air duct. It passes initially through the air filter. Thecirculating blower is an integral part of the furnace, which suppliesheat during winter. An optional

45、humidifier adds moisture to theheated air, which is distributed throughout the home via the supplyduct. When cooling is required, heat and moisture are removed fromthe circulating air as it passes across the evaporator coil. Refrigerantlines connect the evaporator coil to a remote condensing unit lo

Condensate from the evaporator is removed through adrainline with a trap.Figure 2 shows a split-system heat pump, supplemental electricresistance heaters, humidifier, and air filter. The system functions asfollows: Air from the space enters the equipment through the returnair duct, an

The circulating blower is anintegral part of the indoor air-handling portion of the heat pump sys-tem, which supplies heat through the indoor coil during the heatingseason. Optional electric heaters supplement heat from the heatpump during periods of low outdoor temperatur
