AS/NZS 3823.4.3:2014 pdf – Performance of electrical appliances- Air conditioners and heat pumps Part 4.3: Air-cooled air conditioners and air-to-air heat pumps- Testing and calculating methods for seasonal performance factors- Annual performance factor.
3.1
cooling seasonal total load
CSTL
total annual amount of heat that is removed from the indoor air when the equipment is operated for cooling in active mode
3.2
cooling seasonal energy consumption
CSEC
total annual amount of energy consumed by the equipment when it is operated for cooling inactive mode
3.3
cooling seasonal performance factor
CSPF
ratio of the total annual amount of heat that the equipment can remove from the indoor air when operated for cooling In active mode to the total annual amount of energy consumed by the equipment during the same period
3.4
heating seasonal total load
HSTL
total annual amount olheat, Including make’up heat, which Is added to the rndooralr when theequiprnent is operated for heating in active mode
3.5
heating seasonal energy consumption
HSF.C
total annual amount of energy cunsumed by the equipment. including make.up heat, when It Is operated for heating in active mode
3.6
annual performance factor
APF
ratio of the total annual amount of heat that the equipment can remove from and add to the indoor air when operated for cooling and heating, respectively, Inactive mode to the total annual amount of energy consumed by the equipment during the same period
3.7
total annual performance factor
TAPF
ratio of the total annual amount of heat that the equipment can remove from and add to the indoor air to the total annual amount of energy consumed by the equipment, including the active, inactive and disconnected modes
3.8
active mode
mode corresponding to the hours with coaling and heating demand of the building and whereby the cooling or heating function of the unit is switched on
Inactive mode
mode corresponding to the hours when the unit is not operating to meet cooling or heating demand Note ito entry: This mode may Include the operation of a crankcase heater.
3.10
disconnected mode
mode corresponding to the hours when the unit is electrically disconnected from the main power supply
Note 1 to entry: Power consumption is zero.
Calculation of LcsT and CcsE is according to IS0 16358-1, and calculation of LHST and CHSE is according to ISO 16358-2.
For the cooling-only equipment, the annual performance factor (APF) shall be equal to the cooling seasonal performance factor (CSPF).
In case of calculating the total annual performance factor (TAPF], refer to Annex A.
6 Test report
The test report for this part of Iso 16358 shall include the calculation of APF (and TAPF if applicable) and test reports from IS0 16358-1 for cooling and ISO 16358-2 for heating.
