Ventilation routes for heatdissipationSouth Korea’s building energy code covers HVAC in two sections, construction designcriteria and machinery design criteria, with both mandatory and recommended provisions(Table 17).Table 17 The Main Focus of HVAC Requirements in South Korea’s Building Energy CodeMandatoryItemsRecommendedItemsConstruction DesignCriteriaDew condensation/preventionand sealingLayout/sealing/ventilationMachinery Design CriteriaDesign temperature of HVAC/minimumefficiency of pump/pipe insulation/Outside air conditions/heat supply andtransmission facilitiesIndoor temperature/heat supplyfacilities/air conditioning facilities /waterdistribution facilities/ventilation andcontrol facilitiesASHRAE 90.1-2007 (United States) provides comprehensive minimum efficiencyrequirements to a variety of air-conditioning equipment by a wide range of size categoryincluding 1) electronically operated unitary air conditioners and condensing units; 2)electronically operated unitary and applied heat pumps and water chilling packages; 3)electrically operated packaged terminal air conditioners, packaged terminal heat pumps,single-package vertical air conditioners, single-package vertical heat pumps, room airconditioners and room air-conditioner heat pumps; 4) warm air furnaces and combinationwarm air furnaces/air-conditioning units, warm air duct furnaces, and unit heaters; 5) gasand oil fired boilers; and 6) centrifugal chillers.MNECB (Canada) covers minimum energy performance of air-conditioning equipmentwith fewer categories compared to ASHRAE 90.1-2007. Since MNECB was issued in1997, most of its performance requirements have been less stringent than the samecategory in ASHRAE 90.1-2007 (Table 18).48
Table 18 Equipment Performance Standards for Air-cooled Unitary Air Conditioners – ElectricallyOperated (Except Packaged Terminal Air Conditioners and Room Air Conditioners)Class CAN (MNECB) USA (ASHRAE 90.1–2007)73-222.7 kW(250,000 – 760,000 Btu/h)> 222.7 kW(760,000 Btu/h)EER = 8.5IPLV = 7.5EER = 8.2IPLV = 7.5EER: 9.3 – 9.5 (before 1/1/2010); 9.8 –10.0 (as of 1/1/2010);IPLV: 9.5 – 9.7EER: 9.0 – 9.2 (before 1/1/2010); 9.5 –9.7 (as of 1/1/2010);IPLV: 9.2 – 9.4ECBC 2007 (India) refers to other Indian standards and ASHRAE 90.1-2004 for mostair-conditioning equipment. ECBC 2007 provides minimum energy performance of aircooledchiller, centrifugal water-cooled chiller, and rotary screw and scroll compressor.While the minimum energy performance of centrifugal chillers in ASHRAE 90.1-2007 iscategorized by both the exiting chilled water temperature and the condenser flow rate, therequirements of ECBC 2007 are much simpler (Table 19).Table 19 Minimum Efficiencies for Centrifugal ChillersClass IND (ECBC 2007) USA (ASHRAE 90.1-2007)< 530 kW (or < 150 tons)COP = 5.80 COPstd = 5.00, COP: 3.84 to 7.09IPLV = 6.09 IPLVstd = 5.25, NPLV = 4.52 to 8.35>= 530 kW and
