Double-bundle modular electric

A double-bundle water-to-water type modular heat pump is aheat pump (modular HP)

modular heat pump system where heating/cooling energy issimultaneously generated. The modular HP is composed ofone or multiple module units, which can operate individually,by having different combinations of modules, or altogether
by a master control. Run by electricity, the modular HPs in
this methodology are also equipped with power optimization
devices (e.g. inverters) to minimize the electricity
consumption of motors.

Packaged air conditioner

Packaged air conditioner is one of the types of A/C system
which consists of factory-assembled A/C unit. It is used forthe cooling capacity in between 20 and 140 kW per unit.

emissionmeasures

Summaryreduction The project contributes to GHG emission reductions at a newbuilding, by reducing electricity and oil consumption with (an)efficient modular HP(s).

Calculation
emissionsofreference Reference emissions are GHG emissions from electricity and oil
consumption by the reference equipment for the generation of
hot and chilled water. They are calculated by the amount of hotand chilled water utilized by the project building, efficiencies of
the reference equipment and CO2 emission factor of fuel andelectricity which would have been consumed by the reference
equipment. Default values are used for the efficiencies.

Calculationofproject Project emissions are calculated based on the monitored

emissionselectricity consumption by the modular HP(s), other chilledwater generating equipment, oil-fired hot water generating
equipment, and the auxiliary equipment.

Monitoring parameters

・ Quantity of heating energy utilized by the project building
・ Quantity of cooling energy utilized by the project building
・ Oil consumed by the project・ Electricity consumed by the modular HP
・ Electricity consumed by auxiliary electric equipment of themodular HP
・ Electricity consumed by other chilled water generating
equipment
・ Electricity consumed by auxiliary electric equipment of theother chilled water generating equipment

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

A project introduces (a) modular HP(s) to a new building. The total cooling
capacity of the modular HP(s) is altogether less than 176 kW or 600,000 BTU/hr.

Criterion 2

The modular HP(s) introduced under the project has its technical capability toproduce outgoing hot water higher than or equal to 70 degrees Celsius. The value
can be checked against specifications from an equipment supplier.

Criterion 3

In addition to the modular HP(s) installed for project, oil-fired hot water
generating equipment(s) and/or electric-run chilled water generating
equipment(s) may be installed and operated to supply hot and/or chilled water tothe project building. In such cases, the capacity of these additional equipment togenerate hot and/or chilled water is less than or equal to half of the heating
capacity and/or the cooling capacity of the modular HP(s), respectively.

Criterion 4

A plan for not releasing refrigerant used for the modular HP(s) is prepared, if therefrigerant contains CFCs, HFCs, or HCFCs.

F. Establishment and calculation of reference emissions
F.1. Establishment of reference emissions
This methodology applies only to a new building which uses both hot and chilled water.
If the modular HPs are not introduced in the project, an oil-fired boiler and packaged A/C areused. Therefore, reference emissions are calculated from the monitored quantity of heating andcooling energy utilized by the project building during the project multiplied by the efficienciesof the reference equipment (oil-fired boiler and packaged A/C) and the individual emission
factors for electricity and oil which would have been consumed by the reference equipment. For
the efficiencies, default values are used.
This methodology ensures a net emission reduction by following reasons:(i) The reference emission uses conservatively-set default efficiencies for the oil-fired boiler(90%) and the packaged A/C (COP 3.70). They are derived from CDM's methodological tooland Indonesia’s national standard (SNI) respectively; and(ii) The hot and chilled water generated by modular HP(s) is to be utilized within the projectbuilding. It can also be utilized in other buildings nearby. The methodology takes into accountonly the project emissions related to the amount of water supplied to other buildings and not thereference emissions.

F.2. Calculation of reference emissions

The reference emissions are calculated using one of the approaches shown below, depending on
the measurement instruments installed in the project:
