A. Project description
A.1. Title of the JCM project
Installation of High Efficiency Air Conditioning System and Chillers in Semiconductor Factory
A.2. General description of project and applied technologies and/or measures
This project newly installs high efficiency Centrifugal Chillers and Swirling Induction type airconditioning system for a newly constructed clean room (6,250m2) to reduce CO2 emissions
from electricity consumption in the refurbishment of LSI (Large Scale Integration) and image
sensor manufacturing plant at Bangkadi Industrial Park. The project air-conditioning systemdoes not mix the air in the room and cools only the room’s lower layer air, so less cooling
capacity are required compare to the reference system. Air flow rate can also be set lower thanthat of the reference system, reducing power consumption of fan motor. In addition, the projectchiller is equipped with an inverter which contributes to energy-saving by controlling therotation speed of the compressor motor so as to continuously regulate the cooling capacity
against the load to provide air conditioning system with chilled water.

A.6. Contribution from Japan
The proposed project was partially supported by the Ministry of the Environment, Japan(MOEJ) through the Financing Programme for JCM Model projects, which provided financial
support of less than half of the initial investment for the projects in order to acquire JCM credits.

criteria

Criterion 1

Project chiller is a centrifugal chiller with a capacity
which is less than or equal to 1,500 USRt.
* 1 USRt = 3.52 kW

COP for project chiller i calculated under thestandardizing temperature conditions* (COPPJ,tc,i) is
more than the threshold COP values set in the tablebelow. (“x” in the table represents cooling capacity perunit.)

COPPJ,tc,i is calculated by altering the temperature
conditions of COP of project chiller i (COPPJ,i) from the
project specific conditions to the standardizing
conditions. COPPJ,i is derived from specifications
prepared for the quotation or factory acceptance test
data by manufacturer.
2The three installed
chillers are the model“ETI-50”
made by
Mitsubishi
Heavy
Industries, Ltd. The
project chillers are acentrifugal type with thecapacity of 500 USRt
each.
The COP of chiller 1,2&3 (COP PJ, tc, i) was
calculated under thestandardizing
temperature conditionsin the chiller inspection
records provided by themanufacturer. It is 6.15
(chiller 1), 6.59 (chiller2&3) and is more than
5.69 in the table on theleft.

Criterion 3

Periodical check is planned more than one (1) timeannually.

Criterion 4Ozone Depletion Potential (ODP) of the refrigerant
used for project chiller is zero.

Criterion 5

A plan for prevention of releasing refrigerant used for
project chiller is prepared. In the case of replacing theexisting chiller with the project chiller, a plan forprevention of releasing refrigerant used in the existing
chiller to the air (e.g. re-use of the equipment) is
prepared. Execution of this plan is checked at the time3

An annual inspection,
including washing of thetubes, is carried out by
the manufacturer and amaintenance report isprovided.
The refrigerant type of
the project chiller is“ASAHIKLIN AK-134a(HFC-134)” by AGC
Chemicals, whose ODPis zero.
