C_CSEwhere  L_CST                is the cooling seasonal total load (CSTL) to be calculated in accordance with ISO 16358-1 (Unit: Wh) using the defined cooling load and the outdoor temperature bin distribution specified in Table 7.3 and Table 7.4 of the Code respectively. 

 C_CSE        is the cooling seasonal energy consumption (CSEC) to be calculated in accordance with ISO 16358-1 (Unit: Wh) using the defined cooling load and the outdoor temperature bin distribution specified in Table 7.3 and Table 7.4 of the Code respectively. 

The cooling seasonal performance factor shall be calculated based on the measurement results and default values as specified in Table 7.2. Data from other sources are not allowed for use in the calculation. 

7.6.2. Cooling Load 

The defined cooling load is assumed linearly changing depending on the change in outdoor temperature as shown in Table 7.3. 

Table 7.3 – Defined cooling load 

where  ϕ_ful(t100)   is the cooling capacity at t₁₀₀at full load operation condition. 

 t₁₀₀ is the outdoor temperature at 100 % load and t₀is the outdoor temperature at 0 % load. 

7.6.3.  Outdoor Temperature Bin Distribution for Cooling 

The cooling seasonal performance factor (CSPF) shall be calculated at outdoor temperature bin distribution shown in Table 7.4. 

Table 7.4 – Outdoor temperature bin distribution         

7.6.4.  Energy Efficiency Grading 

The energy efficiency grade of the room air conditioner shall be determined as shown in Table 7.5, with Grade 1 having the best performance and Grade 5 having the worst performance. 

Table 7.5 – Derivation of energy efficiency grades 

Note:

In order to obtain Grade 1 to 4, the room air conditioner concerned shall also pass the maximum cooling performance test.  Only Grade 5 will be accorded if the room air conditioner does not pass the maximum cooling performance test; or the F_CSP< 2.40 for single package type room air conditioner or the F_CSP< 2.80 for split type room air conditioner. 

Example illustrating the method on how to determine the energy efficiency grade of room air conditioner is shown in Appendix 1A.

Note:

IEC 62552 “Copyright © 2007 IEC Geneva, Switzerland.www.iec.ch”

8.3.2Overall Classification 

All refrigerating appliances shall be classified in accordance with Table 8.3, which also incorporates the various parameters involved in the classification

Table 8.3 – Overall classification 

8.4.        Tests Required to be Carried Out

The tests specified in this clause are required to be carried out, in accordance with IEC 62552, or other equivalent international standards approved by the Director, in order to find out the energy efficiency and performance characteristics of a refrigerating appliance.  A test report required to be submitted to the Director under section 6 of the Ordinance shall contain the results of these tests: 

(a)       Measurement of storage temperatures of compartments. 

(b)      Measurement of storage volumes of compartments. 

(c)       Energy consumption test. 

(d)      Freezing test (for only food freezer or refrigerating appliance having food freezer compartment). 

The refrigerating appliance shall be tested at a voltage and frequency of mains electricity in Hong Kong with tolerances as specified in the relevant standard. 

8.5.        Test Methodology and Energy Efficiency Grading

8.5.1.Measurement of Energy Consumption 

The methodology for measuring energy consumption (kWh/24h) shall be based on: 

(a)          IEC 62552; or 

(b)          other equivalent international standards approved by the Director. 

The specified international standard shall be referred to for actual performance requirements and procedural descriptions.  The importer or manufacturer shall clearly indicate which test standard(s) they follow in testing their refrigerating appliances. 

8.5.2.Calculation of Adjusted Volume 

The refrigerating appliance storage volumes of the different compartments in litres shall be measured in accordance with the standard specified in clause 8.5.1 of the Code. The respective adjusted volume of the refrigerating appliance shall then be the sum of the measured storage volumes of the different compartments weighted by the difference in temperatures between the interior of the compartments and the ambient temperature. The adjusted volume V_adjis calculated as follows

V_adj= V_ix ………………………………………………………….. (eq. 1) 

                   where        V_i= the measured storage volume of an individual compartment 

= the weighting factor given by the following equation: 

Ta-Ti

                  =             …………………………………………………………….. (eq. 2) 

Ta-Tr where   T_a= test room ambient temperature which is taken as 25 °C 

T_i= the rated temperature in the individual compartment concerned 

T_r = the rated temperature in the fresh food compartment which is taken as 5°C 

A summary of eight simple equations for calculating the adjusted volume of each refrigerating appliance category is shown in Table 8.4. 

Table 8.4 – Adjusted volume (V_adj) calculation for all categories of the 

refrigerating appliances 

where  V _r= Storage volume of fresh food compartment 

V _ffc= Storage volume of frozen food compartment 

Note: These equations are used for those refrigerating appliances with fresh food compartment and frozen food compartment only.  For refrigerating appliances with additional chill compartment and/or cellar compartment, additional terms obtained by calculating equation 2 shall be added to these equations.  For illustration, please refer to Appendix 2A. 

Explanatory note for sample calculation of adjusted volume:

To illustrate how Equation 6 isderived for a category 4 refrigerating appliance:

Category 4 is defined as a refrigerator comprising one fresh foodcompartment (V_r) and one 3-star frozen food compartment (V_ffc).

By equation 1:V_adj= V_ix . 

Total adjusted Volume = (Storage volume of fresh food compartment V_r)+ (Storage volume of weighted 3-star frozen food compartment V_ffc)

From equation 2: 

Vadj= Vrx (  TTaa--TTrr) + Vffcx ( TTaa--TTffcr) ………………………………………………(eq. 11)

Since temperature of a 3-Star compartment is T_i = T_ffc= –18 C, and temperature of a fresh food compartment is T_r= 5C, 

Hence V_adj= V_rx (  ) + V_ffcx (  ) 

                          V_adj= V_r+ 2.15 x V_ffc

8.5.3.Energy Efficiency Definition of Refrigerating Appliances 

(a)       The energy efficiency performance of a refrigerating appliance is defined as the maximum allowable energy consumed per unit storage volume for the storage of food stuff adjusted for the relative contribution to the total energy consumption according to the different temperatures of its compartments with the fresh food storage temperature 5 °C taken as the reference.  For a refrigerating appliance with more than just the fresh food compartment, the energy consumption is not only a function of the refrigerating appliance storage volumes but also the relative sizes of the fresh food and other compartment storage volumes. 

(b)      The energy consumption test measures the energy consumption of the refrigerating appliance in kWh/24h.  The annual energy consumption of the refrigerating appliance is obtained by multiplying the figure of the measured energy consumption (kWh/24h) by 365.

(c)       The energy efficiency of a refrigerating appliance is inversely related to the refrigerating appliance energy efficiency ratio which is expressed in the unit of kWh/year/litre. 

Refrigerating Appliance Energy Efficiency Ratio = 

Annual Energy Consumption

 kWh/yr/litre …………..……………………(eq. 12) 

Adjusted Volume

(i.e. the lower the ratio the better is the energy efficiency) 

8.5.4.Average Appliance Energy Consumption 

(a)       The Average Appliance Energy Consumption line equations developed from equation (12) represent the average annual energy consumption for refrigerating appliances in Hong Kong. 

(b)      The Average Annual Energy Consumption of a refrigerating appliance shall be determined in accordance with Table 8.5. 

Table 8.5 – Average appliance energy consumption 

Note: The figure 1.35 in these equations is the correction factor for no-frost models.

8.5.5.Energy Efficiency Grading 

              (a)    Energy Consumption Index (I_) 

The energy consumption index (I_) of a refrigerating appliance is defined as the ratio of the actual energy consumption of the refrigerating appliance to the Average Appliance Energy Consumption (as found from the associated average annual energy consumption equations in clause 8.5.4 of the Code).  The indices are expressed in percentages.  Thus, within a category, a refrigerating appliance with a lower energy consumption index (i.e. a lower percentage) consumes less energy than a refrigerating appliance with a higher energy consumption index (i.e. a higher percentage).  The energy consumption index is calculated as follows

E

Energy Consumption Index (I_)⁼ _Eavx 100% .....…………………..(eq. 23) 

where 

E = actual annual energy consumption of the refrigerating appliance measured in energy consumption test.

E_av= average annual energy consumption as determined from Table 8.5. 

              (b)   Refrigerating Appliance Energy Efficiency Grading 

The energy efficiency grading of a refrigerating appliance shall be determined as shown in Table 8.6, with Grade 1 having the best performance and Grade 5 having the worst performance.
