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 air conditioner(A/C) system which consists of factory-assembled A/C unit.
It is used for the cooling capacity in between 20 and 140 kW
per unit.

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

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 referenceequipments (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 tool andSNI 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 theI-3
