Terms
Absorption chiller

Definitions
Refrigerating machine using heat source such as heatingenergy generated by fuel combustion and/or waste heat in
the form of hot water, steam or exhaust gas, refrigerant (eg.
water) and absorption solution (eg. Lithium bromide,ammonia) to generate chilled water or other chilled liquids
by absorption refrigeration cycle.

Cooling capacity

Capability of individual chiller to remove heat. In thismethodology, “cooling capacity” is used to represent a
cooling capacity per a single chiller unit and not for asystem with multiple chiller units.

Periodical check

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

C. Summary of the methodology
Items

emissionmeasures

Summary
reduction Absorption chiller is introduced to replace reference centrifugal
chiller(s), which leads to save energy and GHG emission
reductions.

Calculation
emissions

ofreference Reference emissions are GHG emissions from using reference
chiller(s) which is determined as centrifugal chiller in thismethodology. Reference emissions are calculated with coolingenergy of project chiller(s), COP (Coefficient Of Performance)of reference chiller, and CO2 emission factor for consumedelectricity.

pump and cooling tower are excluded from calculation sincethose pumps exist in both reference and project chiller system,and they can cancel each other out.
Calculationofproject Project emissions are GHG emissions from using projectemissionschiller(s), which are the sum of emissions from electricity
consumption and fossil fuel consumption. GHG emissions fromelectricity consumption are calculated with power consumptionof pumps for absorbing solution and refrigerant built in theproject chiller(s) and hot water pumps where applicable andCO2 emission factor for consumed electricity. GHG emissions
from fossil fuel consumption are calculated with fuelconsumption of project chiller(s) and CO2 emission factor forfuel consumed.

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

Project chiller is an absorption chiller with a cooling capacity which is lessthan or equals to 1,300 USRt.
* 1 USRt = 3.52 kW

Criterion 2

Periodical check is planned more than four (4) times annually.

Criterion 3

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.
In the case that the existing chiller is NOT replaced with the project chiller,
this criterion is not applied.

Criterion 4In the case that project absorption chiller uses fossil fuel for its heat source,
such fossil fuel is gas fuel.

F. Establishment and calculation of reference emissions
F.1. Establishment of reference emissions
Reference emissions are calculated with cooling energy of project chiller(s), COP of reference
chiller, and CO2 emission factor for consumed electricity.
GHG emissions from using chilled water pump, cooling water pump and cooling tower are
excluded from calculation since those pumps exist in both reference and project chiller system,and they can cancel each other out.
The COP of reference chiller, which is a centrifugal chiller, is conservatively set as a default
value in the following manner to ensure the net emission reductions.
1. The COP value tends to increase as the cooling capacity becomes larger.
2. The reference COP value varies by the cooling capacity of chillers.
3. The maximum values of COP in each cooling capacity range set for this methodology aredefined as COPRE,i as described in Section I.
