Definitions

Heat recovery electric heat

A heat recovery electric heat pump is a heat pump systempump (HP)

where hot and chilled water is simultaneously generated
through reutilizing waste heat.

Natural refrigerant

Natural refrigerant refers to naturally occurring substanceswith refrigeration capacity and with zero ozone depletion
potential (ODP) (e.g., CO2 and NH3).

Compressor

In this methodology, a compressor signifies positive
displacement refrigeration compressors (e.g. screw andreciprocating types) for industrial applications andexcludes compressors used in a chiller.

Coefficient of Performance

For the purpose of this methodology, COP is defined as a(COP)

ratio of rated cooling capacity to the rated electricity
consumption by a compressor, and it is calculated using
following formula
COP=Q/W
Where:
Q: Rated cooling capacity of a compressor
W: Rated electricity consumption by a compressor
The temperature conditions at which COPs are calculated
in this methodology are shown below:
Condensing temperature: 38 degree CelsiusEvaporating temperature: -5 degree Celsius

Summary

GHG emission reduction

This methodology applies to the project that aims at saving

measuresenergy by introducing (a) heat recovery electric HP(s) in a food
manufacturing process.

Calculation of reference

Reference emissions are GHG emissions from using reference

emissionsequipment for the generation of hot and chilled water. They arecalculated by the ratio of efficiency between reference
equipment and project HPs and CO2 emission factors ofelectricity and fossil fuel consumed.

Calculation of project

Project emissions are GHG emissions from using the projectemissionsHPs and their auxiliary electric equipment, and they arecalculated with their electricity consumption and the CO2emission factor of electricity consumed.

Monitoring parametersElectricity consumption of the project HPs

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

A project newly introduces (a) high efficiency HP(s) using natural refrigerants
to a food manufacturing plant and it does not replace (an) existing HP(s). In
case of HPs supplying chilled water, the water is fed into a refrigeration
system of the plant which uses either screw or reciprocating compressors.

Criterion 2

The cooling capacity of a HP unit is more than or equal to 50kW and less than
1600kW.

F. Establishment and calculation of reference emissions
F.1. Establishment of reference emissions
This methodology only applies to a food manufacturing plant which uses hot and chilled water
for the industrial process.
Reference emissions are calculated by multiplying electricity consumption of the project by theratio of efficiency between a reference equipment and project HPs, and emission factors ofelectricity and fossil fuel consumed.
The reference equipment is identified as a boiler for the hot water generation and acompressor (*1) for the chilled water generation as their loads are partially replaced by theproject HPs. The methodology ensures a net emission reduction by conservatively setting
default efficiency values for both reference boiler and compressor respectively as specified
below:<Boiler>This methodology applies a conservative default value of the reference boiler efficiency as 89[%], which is the highest value among the products sold in Thailand, so as to ensure net
emission reductions.
<Compressor>
This methodology doubly ensures the conservativeness of the default efficiency values ofcompressors, expressed in COPs, in the following manner:1)

The highest design efficiencies of screw- and reciprocating-type models—two main
displacement compressor types used in the food manufacturing industries—areselected from dominant compressor manufacturers' lineups available in Thailand; and2)

The methodology applies COPs for the compressors instead of the one for the whole
refrigeration system whose efficiency is lower than that of the compressors due tosome heat loss in the system.

The default COP value for the calculation of the reference emission can be selected based on the4

JCM_TH_F_PM_ver01.0

rated cooling capacity of the existing compressor at the time of validation.
(*1) The water is fed into a refrigeration system of the plant, which consists of individualcomponents of compressors, evaporators, condensers and other relevant parts mounted together
to form a custom-made system to meet specific needs of the operation. By using the HPs tolower the inlet water temperature of the refrigeration system, the electricity consumption of thecompressor is reduced.
