Definitions

Inverter type centrifugal chiller

An inverter type centrifugal chiller is a chiller which contains
inverter, an apparatus to control the speed of the compressor
motor in order to maintain the ambient temperature, andincludes a centrifugal compressor.

Non-inverter type centrifugal A non-inverter type centrifugal chiller is a chiller whichchiller

includes a centrifugal compressor but does not contain
inverter.

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.

Monitoring parameterPower consumption of project chiller

The amount of fuel consumed and the amount of electricity

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 which is less than or equals
to 1,500 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 the threshold COP values set in the tables
below. (“x” in the table represents cooling capacity per unit.)

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 equipment. 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 emissions
Reference 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 reference COP value varies by its cooling capacity.
2. The maximum values of COP in each cooling capacity range set for this methodology aredefined as COPRE,i as described in Section I.
F.2. Calculation of reference emissions: Reference emissions during the period p [tCO2/p]: Power consumption of project chiller i during the period p [MWh/p]: COP of project chiller i calculated under the standardizing temperature conditions[-]: COP of reference chiller i under the standardizing temperature conditions [-]: CO2 emission factor for consumed electricity [tCO2/MWh]

G. Calculation of project emissions: Project emissions during the period p [tCO2/p]: Power consumption of project chiller i during the period p [MWh/p]: CO2 emission factor for consumed electricity [tCO2/MWh]
