B. Terms and definitions
Terms

Definitions

Separate type fridge-freezer

Refrigeration or freezer system with natural refrigerant of

showcase

which condensing unit and showcase unit are separated andthe condensing unit is located outside the store. The system
includes the following:

Reach-in type fridge showcase or freezer showcase (astructure to interrupt display room from outside air byglass type door)

Open type fridge showcase (a structure to interrupt
display room from outside air by air curtain)

Walk in type fridge showcase (a structure which people
can go in and fill groceries from behind the display
shelves)Natural refrigerant

Natural refrigerant refers to naturally occurring substanceswith refrigeration capacity and with zero ozone depletion
potential (ODP) (e.g., CO2 and NH3).

Built-in type showcase

Refrigeration or freezer system of which condensing unit andshowcase unit are built in one unit.

Coefficient of Performance

Coefficient of Performance (COP) is the cooling capacity per(COP)

rated power consumption of the air conditioning system. The
values of cooling capacity and rated power consumption are
defined under specific temperature stated in ISO 5151:2010.

Energy efficiency

For the purpose of this methodology, energy efficiency of thefridge-freezer showcase is defined as the rated volume (L)I-1

JCM_ID_AM008_ver021.0
Sectoral scope: 03
divided by the rated electricity consumption (W) or the rated
cooling capacity (W) divided by the rated electricity
consumption (W).

C. Summary of the methodology
Items

Summary

GHG emission reduction

This methodology applies to the project that aims for saving total

measuresenergy of in-store showcase and air conditioning system byintroducing a separate type natural refrigerant fridge-freezer
showcase for grocery store in Indonesia, which leads to GHG
emission reductions, through the reduction of air conditioning
electricity load demand by not releasing waste heat inside thestore.

Calculation of reference

Reference emissions are GHG emissions from both the reference

emissionsbuilt-in type fridge-freezer showcase and the reference air
conditioning system.
[Built-in type fridge-freezer showcase]
Reference emissions from the reference fridge-freezer showcase
are calculated with:Electricity consumption of the project fridge-freezer
showcase;Energy efficiency of the project fridge-freezer showcase;Energy efficiency of the reference fridge-freezer
showcase; andCO2 emission factor for consumed electricity.

[Air conditioning system]
Reference emissions from the reference air conditioning system
due to waste heat from the reference fridge-freezer showcase arecalculated with:Electricity consumption of the project fridge-freezer
showcase;Energy efficiency of the project fridge-freezer showcase
in terms of the cooling capacity;Energy efficiency of the project fridge-freezer showcase
in terms of the volume;

Calculation of project[Separate type natural refrigerant fridge-freezer showcase]emissions

Project emissions are calculated with power consumption of
installed separate type natural refrigerant fridge-freezer showcase
and CO2 emission factor for consumed electricity.

Monitoring parametersElectricity consumption of the project fridge showcase

Electricity consumption of the project freezer showcase

D. Eligibility criteria
This methodology is applicable to projects that satisfy all of the following criteria.
Criterion 1

The project is to install a separate type fridge-freezer showcase by using naturalrefrigerant or replacing the existing at a grocery store which is equipped with wall
mounted type and/or ceiling cassette type air conditioning system and whose
selling area is less than 400 (four hundred) m2.

Criterion 2

In the case of replacing the existing fridge-freezer showcase with the project
fridge-freezer showcase, the existing one is a built-in type showcase.

Criterion 3

A plan for not releasing refrigerant used for project fridge-freezer showcase isprepared. In the case of replacing the existing fridge-freezer showcase with the
project fridge-freezer showcase, a plan is prepared in which to prevent release ofrefrigerants used in into the atmosphere is prepared for the existing fridge-freezer
showcase is not released to the air e.g. re-use of the refrigerantreplaced by the
project. Execution of the prevention plan is checked at the time of verification, inorder to confirm that refrigerant used for the existing one replaced by the project is
not released to the air.

F. Establishment and calculation of reference emissions
F.1. Establishment of reference emissions
Reference emissions are GHG emissions from electricity consumption by both the reference
built-in type fridge-freezer showcase and the reference air conditioning system used for coolingthe exhaust heat from the reference fridge showcase.
Net emission reductions in this methodology are achieved by setting default values of “COP of
the reference air conditioning system” in a conservative manner, and also achieved by notincluding “leakage of HFCs from the reference fridge-freezer showcase” when calculating
emission reductions.
[COP of the reference air conditioning system]
The default values of COP of the reference air conditioning system are set in line with theapproved JCM methodology ID_AM004 Ver1.0.
If the air conditioning system equipped in the project store has higher COP values compared tothe table below within the respective cooling capacity range, the COP value of the air
conditioning system installed at the project store is used.
If multiple types of air conditioning system with different cooling capacity rage shown in thetable below are found in the project site, the highest value of COP is selected and applied to
calculate reference emissions in a conservative manner.

Cooling Capacity [kW]2.5 ＜ x ≦ 4.1
4.1 ＜ x ≦ 5.3
5.3 ＜ x ≦ 7.1
7.1 ＜ x ≦ 14.2

Reference COP

3.59

The default COP values may be revised as to the revision of the approved JCM methodology
ID_AM004 to maintain conservativeness.
