Definitions

Inverter-controlled separate type Inverter-controlled separate type fridge showcase is a typefridge showcaseof fridge showcase of which condensing unit and showcase
unit are separated, and the condensing unit equipped withinverter to control the speed of the compressor motor inorder to maintain the temperature is located outside thestore.
The system includes the following:

Reach-in type fridge showcase (a structure to interrupt
display room from outside air by glass type door)

Open type fridge showcase (a structure to interrupt
display room from outside air by air curtain)

Walk in type fridge showcase (a structure which people
can go in and fill groceries from behind the display
shelves)

Coefficient of Performance

Coefficient of Performance (COP) is the cooling capacity(COP)per rated power consumption of the fridge showcase.

Part Load Ratio

Ratio of the actual cooling capacity and rated cooling
capacity.

Degradation coefficient

Measure of efficiency loss due to compressor switching
on/off control by constant speed compressor.

Eligibility criteria

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

Separate-type inverter-controlled fridge showcase is newly installed or installed
to replace existing fridge showcase at convenience store(s).

Criterion 2

COP of project inverter-controlled separate type fridge showcase i under thestandard temperature conditions* is more than the threshold COP values set inthe table below. (“x” in the table represents cooling capacity per unit.)
Cooling capacity [kW]Reference COP

3.0 ≤ x ≤ 15.0

2.20

15.0 < x ≤ 25.0

1.83

*The standard temperature condition are as follows:
Ambient temperature: 32 degrees Celsius
Evaporative temperature: -10 degrees Celsius
Criterion 3

Ozone Depletion Potential (ODP) of the refrigerant used for project fridge showcase is zero.

JCM_TH_F_PM_ver01.0

Criterion 4

A plan for prevention of releasing refrigerant used for project separate-type
fridge showcase is prepared. In the case of replacing the existing showcase withthe project showcase, a plan for prevention of releasing refrigerant used in theexisting showcase to the air (e.g. re-use of the equipment) is prepared.
Execution of this plan is checked at the time 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.

CO2Establishment and calculation of reference emissions

F.1. Establishment of reference emissions
Reference emissions are calculated by multiplying electricity consumption of project invertercontrolled separate type showcase, ratio of energy efficiency (COPs) of project/reference
showcase, part load ratio of the showcase, Degradation coefficient (CD), and CO2 emission
factor for consumed electricity.
In this methodology, energy saving effects through the inverter are conservatively calculated
to ensure the net emission reductions.
The value of CD is conservatively set as a default value according to the survey on thestandard of air conditioner.

The effects of the improvement of efficiency in operation by inverter control in part loadconditions are not taken into account.

F.2. Calculation of reference emissions
For calculation of reference emissions, either Option 1 or Option 2 is selected.
If operating time of project fridge showcase can be measured, Option 2 may be selected.
