greenhouse and energy minimum standards air conditioners and heat pumps determination 2017 proposed changes to the energy efficiency regulations for air conditioners are set out in items one to four below. one adopt a seasonal energy efficiency ratio seer methodology for rating air conditioner energy efficiency by incorporating the following australia new zealand standards into regulation as nzs 3823.4.1 2014performance of electrical appliances - air conditioners and heat pumps - part 4.1 air-cooled air conditioners and air-to-air heat pumps - testing and calculating methods for seasonal performance factors - cooling seasonal performance factor iso 16358-1 2013 mod - including amendment 1 2017. as nzs 3823.4.2 2014 performance of electrical appliances - air conditioners and heat pumps - part 4.2 air-cooled air conditioners and air-to-air heat pumps - testing and calculating methods for seasonal performance factors - heating seasonal performance factor iso 16358-2 2013 mod - including amendment 1 2017. performance of electrical appliances - air conditioners and heat pumps - part 1.5 non-ducted portable air-cooled air conditioners and air-to-air heat pumps having a single exhaust duct - testing and rating for performance. note the standards as nzs 3823.4.1 2014 and as nzs 3823.4.2 2014 listed above are based on parts 1 and 2 of iso 16358 2013 air-cooled air conditioners and air-to-air heat pumps -- testing and calculating methods for seasonal performance factors but they make use of local climate data. amendments to these standards were published in may 2017 to include more realistic operational hours.the three standardslisted above will supplement the following test standards that apply under australian regulation as nzs 3823.1.1 2012 performance of electrical appliances air conditioners and heat pumps - part 1.1 non-ducted air conditioners and heat pumps - testing and rating for performance iso 5151 2010 mod . as nzs 3823.1.2 2012 performance of electrical appliances air conditioners and heat pumps - test methods - ducted air conditioners and air-to-air heat pumps - testing and rating for performance iso 13253 2011 mod . as nzs 3823.1.3 2005 performance of electrical appliances air conditioners and heat pumps part 1.3 water-source heat pumps water-to-air and brine-to air heat pumps - testing and rating of performance iso 13253 2011 mod . as nzs 3823.1.4 2012 performance of electrical appliances air conditioners and heat pumps - part 1.4 multiple split-system air conditioners and air-to-air heat pumps - testing and rating for performance iso 13256-1 ed.01 1998 mod . these standards will also replace the following test standard that as nzs 3823.3 2002 performance of electrical appliances air conditioners and heat pumps - part 3 calculation of performance for minimum energy performance standard meps requirements as nzs 3823.2 2013 performance of electrical appliances air conditioners and heat pumps - part 2 energy labelling and minimum energy performance standards meps requirements. two adopt a zoned energy rating label to replace the existing energy rating label and report seasonal energy efficiency ratings. products u to 30kw capacity products currently requiredto display a label i.e. single-phase non-ducted units including double duct portable air conditioners will need to display a zoned energy rating label in place of the existing energy rating label. productscurrently not requiredto display a label mainly single-phase ducted and three-phrase units will not need to display a label but it will be mandatory to report seer ratings for these products with the ratings to be made available on the energy rating website. products 30kw capacitywill not need to display a label but it will be mandatory to report seer ratings for cooling only for these products with the ratings to be made available on the energy rating website seer ratings for heating based on a physical test report can be provided voluntarily . performance of electrical appliances - air conditioners and heat pumps - part 1.5 non-ducted portable air-cooled air conditioners and air-to-air heat pumps having a single exhaust duct - testing and rating for performance. three changes to meps requirements portable air conditioners performance of electrical appliances - air conditioners and heat pumps - part 2 energy labelling and minimum energy performance standards meps requirementsfor the current requirements. single duct units introduce meps also at a level of 2.5 based on the eer and cop. commercial industrial air conditioners introduce a meps of 2.9 for air conditioners with a capacity of 65 kw based on their annual energy efficiency ratio aeer and annual coefficient of performance acop . note meps for these products currently apply at levels between 2.6 and 2.8 under the national construction code ncc . australia will include these meps at the higher level of 2.9 shown above under the greenhouse energy minimum standards gems act 2012. four minor changes resolve some minor technical issues with air conditioner regulations. these will not have significant impacts on the requirements of regulation. remove h2 meps meeting a separate meps level at the h2 test point will no longer be required. multi-split registration systems comprising of multiple already registered outdoor units will no longer be required to register the combined systems. supply of outdoor units only meps requirements will apply to the supply of outdoor units that are not sold as a system. noise test standard for products 30 kw en 12102 2013 air conditioners liquid chilling packages heat pumps and dehumidifiers with electrically driven compressors for space heating and cooling. measurement of airborne noise. determination of the sound power level will be used. noise rating test points measured at the operating points t1 35 c for the rated capacity cooling test or h1 7 c for heating only units. noise test requirements non-ducted split systems indoor and outdoor noise levels. ducted units both split and unitary units outdoor noise levels only. non-ducted unitary units e.g. window wall units indoor and outdoor noise levels. single and double duct portable unitary units that sit wholly within the conditioned space indoor noise levels only. multi-split systems outdoor noise level of single outdoor units based on the representative combination used for registration. changing the seer degradation coefficient the degradation coefficient from as nzs 3823.4 will be fixed at the default value of 0.25. measurement of non-operative power non-operative power e.g. standby for the meps metric will change to the weighted average power consumption pia of as nzs 3823.4. h2 and h3 testing air enthalpy tests or a shorter calorimeter room test will be accepted for h2 h3 2 c -7 c tests for all air conditioners. use of default seer values fixed speed products will be allowed to use the default values for the 29 c cooling test and variable speed products will be allowed to use the fixed speed test points. certifying test results for 30 kw products eurovent and air conditioning heating and refrigeration institute ahri certification and regional adoptions of international standards organisation iso test standards will be able to be used. simulation testing of 30 kw products simulation software that can be demonstrated to yield equivalent results to a physical test will be able to be used. maximum cooling test will no longer be a requirement for labelled products. rating commercial products products may be rated on either a commercial or domestic operating basis.
