|Title of Study||JCM Project Planning Study|
|Energy Saving by High-efficiency Centrifugal Chiller|
|Main Implementing Entity||Nippon Koei Co., Ltd., and |
Ebara Refrigeration Equipment and Systems Co. Ltd.
|Study Partners||PT. Ebara Indonesia,|
PT. Primatexco Indonesia, and
PT. Argo Pantes
|Location of Project/Activity||Banteng province, and West and Central Java provinces, Indonesia|
|Category of Project/Activity||Energy efficiency|
Note: JCM proposed methodology, and calculation sheet are the result of the study. They have neither been officially approved, nor are guaranteed to be officially approved under the JCM.
|Description of Project/Activity||The proposed JCM projects through this study aim to improve energy saving by introducing high-efficiency chiller in the factory of spinning industry in Indonesia. |
The project covers a spinning factory in Batang in Central Java province, Tangerang in Banteng province, and Bekasi in West Java province in Indonesia. Existing chillers will be replaced to high-efficiency chillers in these factories.
|JCM Methodology||Eligibility Criteria||Following 5 eligibility criteria are set.|
[Criterion 1] Project chiller is a centrifugal water chiller using centrifugal compressor.
[Criterion 2] COP for project chiller is more than 6.0.
[Criterion 3] Regular check is done by manufacturer or agent who is authorized by the manufacturer on regular maintenance or equivalent activities. Frequency of the check is more than four (4) times annually.
[Criterion 4] Ozone Depletion Potential (ODP) of the refrigerant used for project chiller is zero.
[Criterion 5] The plan for recovery and destruction of refrigerant used for project chiller is prepared.
|Default Values||Following 3 default values are set.|
a) Grid emission factor (EF) [tCO2/MWh]: official information from the government of Indonesia
b) COP (reference chiller) (COPRE_PJ) [-]: calculated based in the default values set ex ante
c) COP (project chiller) (COPPJ) [-]: specifications of project chiller prepared for the quotation or factory check by manufacturers
|Calculation of Reference Emissions||Reference emissions are calculated from the monitoring result of project chiller.|
RE = ECPJ * (COPRE_PJ /COPPJ) * EF
RE : Reference Emissions [tCO2/y]
ECPJ : Power consumption by project chiller [MWh]
COPRE_PJ : COP of reference chiller (project condition) [---]
COPPJ : COP of project chiller [---]
EF : Grid emission factor [tCO2/MWh]
|Monitoring Method||Monitoring point is the motor input of project chiller.|
Reading and recording based on the digital power consumption meter. The method and frequency is based in the current monitoring systems of factories (ref: in Primatexco, three times / day, recorded manually on the monitoring form)
|GHG Emission Reductions||Following formula is employed for calculation of GHG emission reductions.
ER = RE – PE
ER : Emission reductions [tCO2]
RE : Reference emissions [tCO2]
PE : Project emissions[tCO2]
The annual GHG emission reductions of PT Primatexco Indonesia and PT Argo Pantes are 156 [tCO2/y] and 205 [tCO2]/y], respectively.
|Environmental Impacts||The proposed JCM projects in this study are the renewal of existing chillers with high efficiency chillers. Thus, no additional environmental impacts are incurred by the projects. Local engineers confirmed that such renewal of chiller does not require any environmental impact assessment or applications to authorities. |
|Project and its Financial Plan||The proposed JCM projects in this study are the renewal of chillers in private spinning factories. The proposed JCM projects are already applied to Ministry of the Environment, Government of Japan as JCM model projects twice with concrete financial plan of the project. |
|Promotion of Japanese Technologies||In this JCM project, Japanese technologies to be promoted are high-efficiency centrifugal chiller. Chillers manufactured by Japanese companies have COP over 6.0, which can achieve energy saving. |
|Sustainable Development in Host Country||Indonesia is the land of perpetual summer and air-conditioning in factories and buildings are inevitable. |
The high efficiency chiller made by Japan contributes to not only saving energy but also improvement of working environment. Also, the Japanese manufacturer can provide after-sales service in order to maintain its performance properly.
