Double-bundle modular

A double-bundle water-to-water type modular heat pump iselectric heat pump (modulara modular heat pump system where heating/cooling energyHP)

is simultaneously generated. The modular HP is composedof one or multiple module units, which can operate
individually, by having different combinations of modules,
or altogether by a master control. Run by electricity, themodular HPs in this methodology are also equipped withpower optimization devices (e.g. inverters) to minimize theelectricity consumption of motors.

Packaged air conditioner

Packaged air conditioner is one of the types of air
conditioner (A/C) system which consists of factoryassembled A/C unit. It is used for the cooling capacity in
between 20 and 140 kW per unit.

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.
Reference emissions are calculated from the monitored quantity of heating and cooling energy
utilized by the project building during the project multiplied by the efficiencies of the reference
equipments (oil-fired boiler and packaged A/C) and the individual emission factors forelectricity and oil which are consumed by the reference equipment. For the efficiencies, default
values from CDM methodological tool and SNI are used.
This methodology ensures a net emission reduction by following reasons:(i) The reference emissions use conservatively-set default efficiencies for the oil-fired boiler(90%) and the packaged A/C (COP 3.70). They are derived from CDM methodological tooland SNI respectively; andI-3

JCM_ID_AM010_ver01.002.0
Sectoral scope: 03(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
the reference emissions.

F.2. Calculation of reference emissions
The reference emissions are calculated using one of the approaches shown below, dependingon the measurement instruments installed in the project:
Approach 1: Where heating and cooling energy is measured by a calorimeter and is expressedin terms of energy utilized by the equipments;
