Inverter-type air conditioning

Inverter-type air conditioning system is a type of airsystem

conditioning system which contains inverter, an apparatus
to control the speed of the compressor motor in order tomaintain the ambient temperature. While the compressor
in a non-inverter-type air conditioning system can only
either operates in maximum capacity or stops entirely, thecompressor in an inverter-type air conditioning system
operates at adjustable speeds.

Coefficient of Performance

Coefficient of Performance (COP) is the cooling capacity(COP)

per rated power consumption of the air conditioningsystem. The values of cooling capacity and rated power
consumption are defined under specific temperature statedin ISO 5151:2010.

Cooling capacity

Cooling capacity is the ability of air conditioning system
to remove heat, calculated with amount of heat removed
per unit time at specific temperature.

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

Single split inverter-type air conditioning system1 is newly installed or
installed to replace existing air conditioning system for grocery store whose
selling area is less than 400 (four hundred) m2.

Criterion 2

The installed air conditioning system is wall mounted type and/or ceiling
cassette type, and has a COP value higher than that of the value indicated in thetable below.

Cooling Capacity [kW]2.5 ＜ x ≦ 4.1

Ozone Depletion Potential (ODP) of the refrigerant used for the installed air
conditioning system is 0 (zero).

Criterion 4A Pplan for not releasing refrigerant used for project air conditioning system isprepared. In the case of replacing the existing air conditioning system with theproject air conditioning system, a plan is prepared in which refrigerant used forthe existing air conditioning system is not released to the air e.g. re-use of therefrigerant. 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 with power consumption of project air conditioning system,
ratio of COPs of project/reference air conditioning system, and CO2 emission factor forelectricity consumed.
The COP of reference air conditioning system is conservatively set ex ante in the following
manner to ensure the net emission reductions.
1. The COP value tends to decrease as the cooling capacity increases.
2. The reference COP, at a certain cooling capacity, is set at a maximum value in therespective cooling capacity range.
3. The maximum values of COP in the respective cooling capacity ranges are defined asCOPRE.
F.2. Calculation of reference emissions
