Category of Project/ActivityEnergy Efficiency Improvement
Study Report

Note: JCM proposed methodology, and calculation sheet are the result of the study. They have neither been officially approved, nor are guaranteed to be officially approved under the JCM.
Description of Project/ActivityThe proposed project is an energy efficiency project mainly in the food & beverage sector in Thailand.

In manufacturing industries, a combination of cooling by chiller and heating by boilers is the most common form of energy generation as shown in the Fig. 1 of the conventional system
JCM MethodologyEligibility Criteria
  1. The project introduces (a) heat recovery heat pump(s) (HPs) that use(s) only electricity to produce heating/cooling energy. It is applicable for a greenfield, expansion, replacement, or partial substitution of project.
  2. Coefficient of Performance (COP) of HPs introduced in the project is capable of being higher or equal under the following 3 conditions: (i) outgoing temperature for heating is higher than or equal to 60 Celsius degree; (ii) temperature difference between incoming and outgoing water or air is higher than or equal to 5 Celsius degree; and (iii) incoming temperature for cooling is lower than or equal to 30 Celsius degree. These values can be checked against, inter alia, specifications from an equipment supplier.
  3. Electricity in the reference and project scenarios is supplied by a connected grid.
  4. The HPs introduced in the project have no ozone depleting potential (ODP) or HFCs.
  5. If the project replaces existing equipment which contains fluorinated gases (e.g. chillers using HFCs as refrigerants), the project proponent needs to collect the fluorinated gases for the future treatment as per the host country government’s national guidelines. If validation is conducted prior to the removal of the existing equipment, confirming that some form of action (e.g. a quotation related to recover of gases) has been taken for recovery of the fluorinated gases is considered fulfilling this requirement. In this case, actual recovery of the gases will be confirmed during verification.
Default Values
  • Efficiencies of the BaU equipment.
  • Value based on material evidence and hearings
  • Thailand energy performance standards and energy-saving standards, T-VER, etc.
Calculation of Reference Emissions
  • Reference emission is calculated on the basis of CO2 emission derived from electricity and fuel consumption of heating/cooling energy generating equipment (“BaU equipment”). The reference emission is determined by the amount of heating/cooling energy generated by the HPs and efficiencies of the BaU equipment.
  • The conservativeness factor is applied, in order to keep the reference emissions always lower than the measured BaU emissions.
  • The reference emission is determined by BaU emissions, which is calculated by using either 1) a measured efficiency of the BaU equipment, 2) an efficiency of the BaU equipment from its specification book, or 3) a default efficiency. Option 2) and 3) are using conservative figures and the reference emissions using those two options are less than the measured BaU emissions.
Monitoring MethodWe made a field study for the efficient method of using HPs referring to the data collected in advance
For calibration of measuring instruments, we think adopting Thai-regulation is appropriate. However, in some cases without such regulation, we applied calibration according to a manual of the supplier.
GHG Emission ReductionsWe calculated reference emission quantity from comparison of efficiency (as mentioned above).
Project emission quantity is calculated from electricity usage of HPs and its supporting devices.
GHG emission quantity are;
    1. Thai-Otsuka: 170 tCO2/year
    2. CPF: 1,170 tCO2/year
Environmental ImpactsThis technology does not cause negative effect as air pollution and/or global warming because our technology does not use fossil fuel directly (not as conventional boiler) or reduce consumption of them.
Since our product uses natural refrigerant, it is more environment conscious than standard systems.
Since refrigerant disposing system is not established in Thailand, at the renewal time for equipment which uses Freon gas, we can recover it by applying Japanese recovery technology instead of discharging out to the atmosphere.
Project PlanSince efficiency of HPs technology has been proved from this research, Implementation probability of this project is very high once the Japan-Thai treaty is agreed.
Promotion of Japanese TechnologiesEven according to COP3, the energy-saving standard which recommended by Thai government, The HPs could be distinguished from other products as A) it uses natural refrigerant and B) produces hot water over 60 degree .
Sustainable Development in Host CountryThai government focus on energy saving in industry Sector.
Introducing advanced Japanese technology (of HPs) will A) reduce CO2 emission and
B)mitigate dependence on imported fossil fuel and will balance foreign currency reserve of Thailand.
Also, this project will support Thailand to develop in energy saving technology, Non Freon technology and other advanced technology areas.
