A. Title of the methodology
Energy Saving by Introduction of High Efficiency Centrifugal Chiller, Version 1.0

B. Terms and definitions
Terms
Centrifugal chiller

Definitions
A centrifugal chiller is a chiller applying a centrifugal
compressor. It is commonly used for air-conditioning withhuge 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 torepresent a cooling capacity per one chiller unit and not for asystem with multiple chiller units.

Periodical check

Periodical check is a periodical investigation of chiller doneby manufacturer or agent who is authorized by themanufacturer, in order to maintain chiller performance.

reference Reference emissions are GHG emissions from using reference
chiller, calculated with power consumption of project chiller,
ratio of COPs (Coefficient Of Performance) of reference/projectchillers and CO2 emission factor for electricity consumed.

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

Project chiller is a centrifugal chiller with a capacity of less than 1,150 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 standardizingconditions. COPPJ,i is derived in specifications prepared for the quotation orfactory acceptance test data at the time of shipment by manufacturer.

Periodical check is conducted at least twice a year.

Criterion 4

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

Criterion 5

A plan for not releasing refrigerant used for project chiller is prepared. In thecase of replacing the existing chiller with the project chiller, a plan is prepared inwhich refrigerant used in the existing chiller is not released to the air e.g. re-useof the refrigerant. Execution of the prevention plan is checked at the time ofverification, in order 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 emissionsReference emissions are calculated by multiplying power consumption of project chiller, ratioof COPs for reference/project chillers, and CO2 emission factor for electricity consumed.
The COP of reference chiller is conservatively set as a default value in the following manner toensure the net emission reductions.
1. The COP value tends to increase as the cooling capacity becomes larger.
2. The reference COP, which has a certain cooling capacity, is set at a maximum value incorresponding cooling capacity range.
3. The maximum values of COP in each cooling capacity ranges are defined as COPRE,i asdescribed in Section I.
