1. Outlines of the model project (3/3)
Background :
To enhance textile quality in Indonesia, it is required to provide
suitable temperature and sufficient moisture. Centrifugal chiller is
the best solution for this requirement. Meanwhile the factory
needs considerable amount of energy, and the chillers consume
significant amount of electricity compared with the other
machines in the factory.
Accordingly, PT Primatexco Indonesia would like to consider
energy saving urgently, in term of sound factory management.
Objective :
The JCM project aims to improve energy saving for airconditioning and process cooling by renewal of high-efficiency
centrifugal chiller.

Table 1 : Terms and Definitions
Centrifugal chiller
Cooling capacity
Periodical check
A centrifugal chiller is a chiller applying a
centrifugal compressor. It is commonly used for airconditioning with huge cooling load, e.g., buildings,
shopping malls or factories etc.
Cooling capacity is the ability of individual chiller to
remove heat. In this methodology, “cooling
capacity” is used to represent a cooling capacity
per one chiller unit and not for a system with
multiple chiller units.
Periodical check is a periodical investigation of
chiller done by manufacturer or agent who is
authorized by the manufacturer, in order to
maintain chiller performance.

3. JCM Methodology (2/6) eligibility criteria
Criterion 1
Project chiller is a centrifugal chiller with a capacity of less
than 1,250 USRt. (1 USRt = 3.52 kW)
Criterion 2
COP for project chiller i calculated under the standardizing
temperature conditions* (COPPJ,tc,i) is more than 6.0.
COPPJ,tc,i is a recalculation of COP of project chiller i (COPPJ,i)
adjusting temperature conditions from the project specific condition
to the standardizing conditions. COPPJ,i is derived in specifications
prepared for the quotation or factory acceptance test data at the
time of shipment by manufacturer.
[Equation to calculate COPPJ,tc,i]
COPPJ,tc,i = COPPJ,I x [(Tcooling-out,i – Tchilled-out,i + TDchilled + Tdcooling) ÷ (37 – 7 + TDchilled + TDcooling)]

: COP of project chiller i calculated under the standardizing temperature conditions* [-]
: COP of project chiller i under the project specific conditions [-]
: Output cooling water temperature of project chiller i set under the project specific condition [degree Celsius]
: Output chilled water temperature of project chiller i set under the project specific condition [degree Celsius]
: Temperature difference between condensing temperature of refrigerant and output cooling water temperature
1.5 degree Celsius set as a default value [degree Celsius]
TDchilled
: Temperature difference between evaporating temperature of refrigerant and output chilled water temperature,
1.5 degree Celsius set as a default value [degree Celsius]
* The standardizing temperature conditions to calculate COPPJ,tc,i : chilled water: output 7 degree Celsius input 12

3. JCM Methodology (4/6) eligibility criteria
Criterion 3
Periodical check is planned more than four (4) times
annually.
Criterion 4
Ozone Depletion Potential (ODP) of the refrigerant used
for project chiller is zero. (See Table 2)
Criterion 5
Plan for not releasing refrigerant used for project chiller is
prepared. In the case of replacing the existing chiller with
the project chiller, refrigerant used for the existing chiller is
not released to the air.

3. JCM Methodology (5/6) reference/project emissions
Reference emissions are GHG emissions by power consumption of
chiller operation, in case of applying to reference chiller.
REp = ∑ { ECPJ,i,p x ( COPPJ,tc,i / COPRE,i ) x EFelec }
REp
: Reference emissions during the period p [tCO2/p]
ECPJ,i,p : Power consumption of project chiller i during the period p [MWh/p]
COPPJ : COP of project chiller [---]
COPRE,i : COP of reference chiller [---]
EFelec : CO2 emission factor for consumed electricity [tCO2/MWh]
Project emissions are GHG emissions by power consumption of chiller
operation, in case of applying to project chiller.
PEp = ∑ ( ECPJ,i,p x EFelec )
PEp
: Project emissions during the period p [tCO2/p]
ECPJ,i,p : Power consumption of project chiller [MWh/p]
EFelec
: CO2 emission factor for consumed electricity [tCO2/MWh]

3. JCM Methodology (6/6) GHG emission reductions
ERp = REp – PEp
ER : Emission reductions during the period p[tCO2/p]
RE : Reference emission reductions during the period p [tCO2/p]
PE : Project emissions during the period p [tCO2/p]
