Definitions

Centrifugal chiller

A centrifugal chiller is a chiller equipped with a centrifugal compressor.
It is commonly used for air-conditioning with huge cooling load, e.g.,buildings, shopping malls or factories etc.

Cooling capacity

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

Periodical check is a periodical investigation of chiller done by
manufacturer or agent who is authorized by the manufacturer, in order tomaintain chiller performance.

IPLV (IntegratedIPLV is a performance indicator of chillers described as a weighted

Part Load Value)

average of the energy efficiency ratio (EER [kW/kW]) under four
different part loads and it is defined in the standard “AHRI Standard
550/590(I-P)” or “AHRI Standard 551/591(SI)” by the Air-Conditioning,Heating, and Refrigeration Institute (AHRI) of the United States.

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

Project chiller is an inverter type centrifugal chiller with a capacity greater thanor equal to 165USRt but less than 3500USRt.
Note : 1 USRt = 3.52 kW

Criterion 2

IPLV for project chiller i certified by AHRI is more than the threshold IPLV
values set in the table below. (“x” in the table represents cooling capacity perunit.)

Criterion 3

Periodical check is planned more than one (1) time annually.

Criterion 4

Ozone Depletion Potential (ODP) of the refrigerant used for project chiller iszero.

Criterion 5

A plan for prevention of releasing refrigerant used for project chiller is prepared.
In the case of replacing the existing 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 thetime of verification, in order to confirm that refrigerant used for the existing one
replaced by the project is prevented from being released to the air.

F.1. Establishment of reference emissions
Reference emissions are calculated by multiplying power consumption of project chiller, ratioof IPLVs for reference/project chillers, and CO2 emission factor for electricity consumed.
The IPLV of reference chiller is conservatively set as a default value in the following manner toensure the net emission reductions.
1. The reference IPLV value varies by its cooling capacity.
2. The maximum values of IPLV in each cooling capacity range set for this methodology aredefined as IPLVRE,i as described in Section I.

CO2 emission factor for consumed electricity.
When project chiller consumes only grid electricity or
captive electricity, the project participant applies theCO2 emission factor respectively.
When project chiller may consume both grid electricity
and captive electricity, the project participant applies
the CO2 emission factor for grid and captive electricity
