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 as nzs 3823.1.5 2015 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 at the request of industry .as nzs 3823.1.1 2012 performance of electrical appliances - airconditioners and heat pumps - part 1.1 non-ducted airconditioners and heat pumps - testing and rating for performance iso 5151 2010 mod as nzs 3823.1.2 2012 performance of electrical appliances - airconditioners and heat pumps - test methods - ducted airconditioners and air-to-air heat pumps - testing and rating for performance iso 13253 2011 mod as nzs 3823.1.4 2012 performance of electrical appliances - airconditioners and heat pumps - part 1.4 multiple split-system airconditioners and air-to-air heat pumps - testing and rating for performance iso 15042 2011 mod these standards will also replace the following test standard that currently applies under new zealand and australian regulation as nzs 3823.3 2002 performance of electrical appliances - airconditioners and heat pumps - part 3 calculation of performance for minimum energy performance standard meps requirements two adopt a zoned energy rating label to replace the existing energy rating label and for products not required to display a label report seasonal energy efficiency ratings on the energy rating website. products u to 30kw capacity products currently requiredto display a label i.e. single-phase non-ducted units 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 on the energy rating website products 30kw capacitywill not need to display a label but it will be mandatory to report seer ratings for these products for cooling only 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 ducted units introduce meps also at a level of 2.5 based on the eer and cop. residential air conditioners align new zealand and australian cooling meps levels for residential products i.e. products with a rated cooling capacity of u to 65kw . note new zealands cooling meps are set below australias due to historic concerns that raising cooling levels meps would restrict availability of products used only for heating in the new zealand market. however these concerns are no longer valid. commercial industrial air conditioners introduce meps for air conditioners with a capacity of 65 kw at a level of 2.9 based on their annual energy efficiency ratio aeer and annual coefficient of performance acop . note these meps for these products will be new to new zealand but theycurrently apply at lower levels in australia under the national construction code ncc . australia will remove these meps from the ncc in australia and include them at the higher level shown above under the greenhouse energy minimum standards gems act 2012. fourminor 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 h2 meps level 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. noise rating test points measured at the operating points t1 35c for the rated capacity cooling test or h1 7c 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 2c -7c tests for all air conditioners. use of default seer values fixed speed products will be able to use the default values for the 29c 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 ahri certification and regional adoptions of 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.
