Definitions

Multi-stage oil-free air

A device with more than one compression stage withoutcompressor

using lubricating oil to compress air, nitrogen or inert gases
to make the pressure of gas higher than that of the inlet.

Specific conditions

The specific conditions for this methodology are defined as
below, following ISO 1217:2009.
Ambient temperature = 20 degrees Celsius,
Ambient pressure = 0 MPa (Gauge pressure),
Relative humidity = 0%,
Cooling water/air = 20 degrees Celsius,
Effective working pressure at discharge valve = 0.7 MPa(Gauge pressure).

Free air delivery (FAD)

The actual quantity of compressed air converted to the inlet
conditions of the compressor. The unit is m3/min.

Periodical check

A periodical investigation of air compressor conducted bymanufacturer or agent who is authorized by the manufacturer,
in order to maintain air compressor performance.

JCM_TH_AM002_ver021.0
Sectoral scope: 03

Reference emissions are calculated by multiplying power consumption of project air
compressor, specific power (SP) for reference/project air compressors, and CO2 emission factor
for electricity consumed.
SP of reference air compressor is conservatively set as a default value in the following manner
to ensure the net emission reductions.
1. The most efficient value is selected for each motor power of air compressors from thecollected SP values available in Thai market and determined as the reference SP.

2. The value of SP is defined as SPRE,sc,i described in Section I.
