3. Air conditioners, except single ducts and double ducts

This section describes for cooling and heating the method for calculating the seasonal energy performance and annual electricity consumption of air conditioners, except single and double duct air conditioners.

3.1. SEER

The SEER is the seasonal energy efficiency ratio for cooling and is calculated as:

EERbin(Tj) is the bin-specific energy efficiency ratio that applies to bin j, calculated according to the equations below for either fixed, staged or variable capacity units, where:

3.1.1. For fixed capacity units

Calculate the anchor points EERbin(Tj) for the bin temperatures specified below to be used in inter- and extrapolations for EERbin(Tj) values at other bins.

Calculate for Tj=35 °C:

EERbin(Tj) = EERd(Tj ) Equation 7

for Tj=30, 25, 20°C:

EERbin(Tj) = EERd(Tj)*[1 – Cdc*(1 – Pc(Tj)/Pdc(Tj))] Equation 8

where:

Cdc= (1 – EERcyc/EERd(Tj))/(1 – Pcycc/Pdc(Tj)) Equation 9

where:

— for bins j with an outdoor temperature Tj higher than 35 °C EERbin(Tj) values shall have the same value as EERbin(Tj=35 °C).

The manufacturer shall declare for each test condition the cooling capacity (Pdc(Tj)) and efficiency (EERd(Tj)) of the equipment at both settings, to be indicated with "_ hi " for the setting resulting in the highest capacity and "_ lo " for the setting that results in the lower capacity. The anchor points EERbin(Tj) are calculated from Pdchi, Pdclo and EERd hi, EERdlo values for capacity and efficiency as follows:

For Tj = 35 °C:

EERbin(Tj) = EERd(Tj) hi Equation 10

for Tj = 30, 25, 20 °C:

if Pdesignc*pl(Tj)*(1 – tolerance) ≤ Pdc(Tj)lo ≤ Pdesignc*pl(Tj)*(1 + tolerance), then:

EERbin(Tj) = EERd(Tj)lo Equation 11

where:

tolerance = 10 % Equation 12

if Pdesignc*pl(Tj)*(1 – tolerance) ≤ Pdc(Tj) hi ≤ Pdesignc*pl(Tj)*(1 + tolerance), then:

EERbin(Tj) = EERd(Tj)hi Equation 13

where tolerance is as defined above.

if Pc(Tj) > Pdc(Tj)lo then:

Equation 14

else:

EERbin(Tj)= EERdlo · [1 – Cdc · (1 – Pc(Tj) / Pdc(Tj)lo) ] Equation 15

where:

where:

EERcyc and Pcycc are as defined above;

EERbin(Tj) values for bins j with outdoor temperatures Tj other than Tj = 35, 30, 25 and 20 °C are calculated according to the same rules applicable to fixed capacity units.

3.1.3. For variable capacity units

Calculate the anchor points EERbin(Tj) for the bin temperatures specified below to be used in inter- and extrapolations for EERbin(Tj) values at other bins.

If the capacity control of the unit allows it to operate with a capacity Pdc(Tj) corresponding to the required part load Pdesignc * (pl(Tj) ± tolerance ), the EERbin(Tj) for bin j shall be assumed to be equal to EERd(Tj).

Calculate for Tj = 35, 30, 25 and 20 °C:

if Pdesign*pl(Tj)*(1 – tolerance) <Pdc(Tj) < Pdesign*pl(Tj)*(1 + tolerance) then:

EERbin(Tj) = EERd(Tj) Equation 17

where:

tolerance, Pdc(Tj), Pdesignc, pl(Tj), EERbin(Tj) and EERd(Tj) are as defined above;

else: follow the calculation procedure for staged capacity units.

3.2. SCOP

The SCOP is the seasonal coefficient of performance for heating. The calculation of the SCOP shall be specific for a designated heating season (average/warmer/colder), since the bins that apply, the reference design temperature and the design load are specific for a heating season. The calculations below show the generic approach which will have to be repeated for each designated heating season.

The Seasonal coefficient of performance for heating is calculated as:

SCOP= QH / QHE Equation 18

where:

QH is the reference annual heating demand [kWh/a], calculated as;

QH = Pdesignh * HHE Equation 19

where:

Pdesignh is the design load for heating [kW] which is calculated from the declared bivalent point Tbiv (Tbiv provides pl(Tj) for Tj=Tbiv) and the declared capacity Pdh(Tj) at Tj=Tbiv. As such Pdesignh, as declared in Table 1, represents the heat load at Tj=Tdesignh operation condition, where pl(Tj) = 1.00;

HHE is the equivalent active mode hours for heating [hrs], as provided in Table 8

QHE is the seasonal electricity consumption for heating [kWh/a], calculated as:

QHE = (QH / SCOPon) + HTO · PTO + HCK · PCK + HOFF · POFF + HSB · PSB Equation 20

where:

QH is as above;

HTO , HCK , HOFF , HSB are the number of seasonal operating hours (hrs/a) for heating in respectively thermostat-off, crankcase heater operation, off-mode and stand-by mode, given in Table 8;

PTO , PCK , POFF , PSB is the electric power input [kW] in respectively thermostat-off, crankcase heater operation, off- and stand-by mode;

SCOPon is the average seasonal coefficient of performance, constructed from bin-specific coefficients of performance, and weighted by the seasonal hours the bin condition occurs, and including back up power consumption for bins where Pdh(Tj) < Ph(Tj):

Equation 21

where:

Tj, j, n, and hj are as defined before;

Ph(Tj) is the heating load at bin j, calculated as:

Ph(Tj) = Pdesignh*pl(Tj) Equation 22

where:

pl(Tj) = (Tj– 16) / (Tdesignh – 16) Equation 23

Tdesignh is the heating season reference design temperature in °C, from Table 5, which is determined by the designated heating season;

elbu(Tj) is the capacity of a back up heater [kW] for bin j, needed to meet the heating part load if the declared capacity does not suffice, calculated as:

if Pdh(Tj) < Ph(Tj): elbu(Tj) = Ph(Tj) – Pdh(Tj) Equation 24 if Pdh(Tj) ≥ Ph(Tj): elbu(Tj) = 0 Equation 25

Pdh(Tj) is the declared heating capacity applicable to bin j, to be calculated using the declared values of Pdh(Tj) at testing points Tj = – 15, – 7, 2, 7, 12 °C and/or Tbiv, the availability of which depends on which heating season is designated (see table 6 for required declaration points per heating season). Pdh(Tj) for other bins than specified shall be calculated through linear interpolation of declared capacities Pdh(Tj) at the nearest outdoor temperatures. Only in case of the average heating season and the colder heating season not being one of the designated seasons (i.e. COP(– 15) is not available) an exception to this rule can be made whereby the COPbin(Tj) values for outdoor temperatures – 8, – 9 and – 10 °C can be linearly extrapolated from the COPd(Tj) of the anchor points at – 7 °C and 7 °C for fixed capacity units. For variable capacity units, these values shall be extrapolated from COPd(– 7) and COPd(Tbiv). In case Tbiv = – 7 °C, COP(– 8), COP(– 9), and COP(– 10) shall be assumed to equal to COP(– 7); If the designated heating season is ‧colder‧, and the lowest Pdh is at – 15 °C, the capacities for Pdh with Tj < – 15 °C shall be based on extrapolations from values at Tj = – 15 °C and – 7 °C.

COPbin(Tj) is the bin-specific coefficient of performance that applies to bin j, calculated according to the equations below for either fixed, staged or variable capacity, where:

3.2.1. For fixed capacity units

Calculate the anchor points COPbin(Tj) for the bin temperatures specified below to be used in inter- and extrapolations for COPbin(Tj) values at other bins.

Calculate for Tj = 12, 7, 2, – 7, – 15 °C (9), (10)), Tbiv:

if Pdh(Tj) ≥ Ph(Tj) (in this condition the fixed capacity unit will cycle)

COPbin(Tj))= COPd(Tj)* [1 – Cdh * (1 – Ph(Tj)/Pdh(Tj))] Equation 26

else if Pdh(Tj) < Ph(Tj) (this corresponds to a situation where backup heating is required to meet the heating load):

COPbin(Tj) = COPd(Tj) Equation 27

where:

COPd(Tj) is the coefficient of performance at the specified outdoor temperature Tj, as declared by the manufacturer in Table 1;

Pdh(Tj) is the heating capacity at the specified outdoor temperature Tj, as declared by the manufacturer in Table 1;

Ph(Tj) is the part load in kW at the specified outdoor temperature Tj, as defined in equation 5.

Cdh is the degradation factor for heating, either taken as default value 0,25 or equal to Cdc (for cooling) or determined by tests and calculated for Tj = 12 °C as:

Cdc= (1 – COPcyc/COPd(Tj))/(1 – Pcych/Pdh(Tj)) Equation 28

where:

COPcyc is is the average coefficient of performance over the cycling test interval (active + off mode) calculated as the integrated heating capacity over the interval [kWh] divided by the integrated electric power input over that same interval [kWh];

Pcych is the (time-weighted) average heating capacity output [kW] over the cycling test interval (active + off mode);

Values for COPbin(Tj) at other bins shall be calcutaled as follows: — for bins j with outdoor temperatures Tj between 12, 7, 2, – 7, – 15 °C (see footnote 6, 7) and Tbiv, COPbin(Tj) is calculated from linear inter- and extrapolation from the nearest two known anchor points; — Only in case of the average heating season and the colder heating season not being one of the designated seasons (i.e. COP(– 15) is not available) an exception to this rule can be made whereby the COPbin(Tj) values for outdoor temperatures – 8, – 9 and – 10 °C can be linearly extrapolated from the COP of the anchor points at – 7 °C and 7 °C; — for bins j with an outdoor temperature Tj higher than 12 °C, COPbin(Tj) is calculated through linear extrapolation with the outdoor temperature starting from anchor points COPbin(Tj) with Tj = 7 and Tj = 12; — for bins j with an outdoor temperature Tj lower than Tol, COPbin(Tj) is equal to ‧1‧ in order to avoid a division by zero, but effectively the value is irrelevant because [Ph(Tj)-elbu(Tj)] in the equation for SCOPon (eq. 20) is equal to zero.

3.2.2. For staged capacity units

Calculate the anchor points COPbin(Tj) for the bin temperatures specified below to be used in inter- and extrapolations for COPbin(Tj) values at other bins.

The manufacturer shall declare for each required test condition (with outdoor temperatures Tj = 12, 7, 2, – 7, – 15 °C (see footnote 6, 7) and Tbiv, depending on the designated heating season) the heating capacity (Pdh(Tj)) and coefficient of performance (COPd(Tj)) of the equipment at both possible settings, to be indicated with "_ hi " for the setting resulting in the highest capacity and "_ lo " for the setting that results in the lower capacity. The anchor points COPbin(Tj) are calculated from Pdhhi, Pdhlo and/or COPdhi, COPdlo values for capacity and efficiency as follows:

Calculate for Tj = 12, 7, 2, – 7, – 15 °C (see footnote 6, 7), Tbiv:

if Pdesignh*pl(Tj)*(1 – tolerance) ≤ Pdhlo ≤ Pdesignh*pl(Tj)*(1 + tolerance), then

COPbin(Tj) = COPdlo Equation 29

where tolerance is as defined before.

if Pdesignh*pl(Tj)*(1 – tolerance) ≤ Pdhhi ≤ Pdesignh*pl(Tj)*(1 + tolerance), then

COPbin(Tj) = COPdhi Equation 30

where tolerance is as defined before.

else if Ph(Tj) > Pdh(Tj)lo and Ph(Tj) < Pdh(Tj) hi then

Equation 31

else:

COPbin(Tj) = COP(Tj)lo · [1 – Cdhlo · (1 – Ph(Tj) / Pdh(Tj)lo) ] Equation 32

where:

COPd(Tj) hi and COPd(Tj)lo are declared coefficient of performance values in Table 1;

Pdh(Tj) hi and Pdh(Tj)lo are declared values in Table 1;

Ph(Tj) is the heat load for bin j with Tj is 7, 2, – 7, – 15 °C (see footnote 6, 7);

Cdhlo is the degradation factor for heating, which is either the default value 0,25, or equal to Cdc (for cooling) or determined by tests and calculated for Tj = 12 °C as:

Cdc = (1 – COPcyc/COPd(Tj)lo)/(1 – Pcych/Pdh(Tj)lo) Equation 33

where:

COPcyc and Pcych are as defined before;

COPbin(Tj) values for bins j with outdoor temperatures Tj other than Tj = 7, 2, – 7, – 15 °C (see footnote 6, 7) are calculated according to the same rules as those applying to fixed capacity units.

3.2.3. For variable capacity units

Calculate the anchor points COPbin(Tj) for the bin temperatures specified below to be used in inter- and extrapolations for COPbin(Tj) values at other bins.

If the capacity control of the unit allows it to operate with a declared capacity Pdh(Tj) corresponding to the required part load Pdesignh*(pl(Tj) ± tolerance ) the COPbin(Tj) for bin j shall be assumed to be equal to COPd(Tj);

Calculate for Tj = 12, 7, 2, – 7, – 15°C (see footnote 6, 7):

if Pdesign*pl(Tj)*(1 – tolerance) ≤ Pdc(Tj) ≤ Pdesign*pl(Tj)*(1 + tolerance), then:

COPbin(Tj) = COPd(Tj) Equation 34

where:

tolerance, Pdh(Tj), Pdesignh, pl(Tj), COPbin(Tj) and COPd(Tj) are as defined before;

else: follow the calculation procedure for staged capacity units.

3.3. Determination of PTO, PSB, POFF and PCK

3.3.1. Determination of PTO

The power consumption during thermostat off mode is obtained during the cyclic tests required to determine the Cd and Cc values.

If no cyclic test is performed, after the test at 20 °C in cooling mode (for cooling only or reversible units), the thermostat set point is increased until the compressor stops. The standby power consumption is deducted from the measured total power consumption of the unit to determine the thermostat off power consumption on a time period not inferior to one hour.

3.3.2. Determination of PSB

At the condition of 35 °C ambient temperature in cooling mode, the unit is stopped with the control of the device. After 10 minutes, the residual power consumption is measured and assumed to be the standby mode power consumption.

For heating only units, the measurements are done in the same way, but at the condition of 12 °C ambient temperature.

3.3.3. Determination of POFF

Following the standby mode power test, the unit should be switched in off mode while remaining plugged. After 10 minutes, the residual power consumption is measured and assumed to be the off mode power consumption.

In case no off mode switch is available on the unit (e.g. on the indoor unit(s) for split units), the off mode power consumption is supposed equal to the standby mode power consumption.

3.3.4. Determination of PCK

The test is performed in heating mode, at 2 °C ambient temperature. The unit is stopped with the control of the device after at least 20 minutes of heating operation, and the energy consumption of the unit shall be measured for 8 hours. If unit does not have function for heating, it shall be operated with cooling mode. Average of 8 hour power input shall be calculated.

The standby power consumption is deducted from this measured power consumption to determine the crankcase heater operation power consumption.

4. Single ducts and double ducts

4.1. EER

The energy efficiency ratio EERd(Tj) for single ducts and double ducts is declared for Tin and Tj at standard rating conditions and calculated as:

EERd(Tj) = Pdc(Tj) / PEER Equation 35

Where:

Pdc(Tj) is the declared capacity for cooling in kW, at standard rating conditions as required in Table 4;

PEER is the total electric power input to the appliance in kW, at standard rating conditions as required in Table 4.

4.2. COP

The coefficient of performance COPd for single ducts and double ducts shall be declared for Tin and Tj at standard rating conditions and calculated as:

COPd(Tj) = Pdh(Tj) / PCOP Equation 36

where:

Pdh(Tj) is the declared capacity for heating in kW (of the vapour compression cycle only), at standard rating conditions as described in Table 4;

PCOP is the total electric power input to the appliance in kW, at standard rating conditions as described in Table 4.

4.3. Seasonal electricity consumption

The electricity consumption QDD in kWh/60 min. of double ducts is calculated for cooling or heating as:

for cooling QDD = HCE·PEER + HTO·PTO + HSB·PSB + HOFF·POFF + HCK·PCK Equation 37 for heating QDD = HHE·PCOP + HTO·PTO + HSB·PSB + HOFF·POFF + HCK·PCK Equation 38

where:

HCE, HHE, HTO, HSB, HOFF, HCK are the number of operating hours (h) for cooling respectively heating in respectively active mode, thermostat-off mode, stand-by mode, off-mode and crankcase heater operation mode, as described in Table 8;

PEER, PCOP, PTO, PSB, POFF, PCK are the average electric power consumption values for respectively rated power input for cooling (PEER ) or heating (PCOP ) in thermostat-off mode, stand-by mode, off-mode and crankcase heater operation mode, as declared by the manufacturer.

The electricity consumption of single ducts QSD in kWh/60 min will be expressed for the active mode only, using as equivalent active mode hours (HCE, HHE) a value of 1:

for cooling QSD = HCE·PEER Equation 39 for heating QSD = HHE·PCOP Equation 40

where:

PEER and PCOP are as defined above.

Annex A: The graph below shows (for heating) the relationship of the bivalent point Tbiv and the part load, including the design load for heating at Tdesignh (where part load equals 1). The area where part load exceeds the declared capacity is considered to be met by electric back up heating.
