A. Project description
A.1. Title of the JCM project
Installation of Energy Saving Equipment in Lens Factory
A.2. General description of project and applied technologies and/or measures
Energy saving equipment, namely inverter type centrifugal chiller and heat recovery electricheat pump (hereinafter referred to as HREHP), are installed at the lens factory of HOYA LENSVIETNAM LTD (hereinafter referred to as HOLV) located in Thu Dau Mot City, Binh Duong
Province, Viet Nam.
Installation of centrifugal chiller improves energy efficiency of chiller, which leads to GHG
emission reductions. One centrifugal chiller manufactured by Mitsubishi Heavy Industries(product model type “ETI­50”) is installed for this project.
Installation of HREHP leads to reduction of energy consumption by electric heater for heatingenergy generation and air­cooled chiller for cooling energy generation, which leads to GHG
emission reductions. One HREHP manufactured by Toshiba Carrier Corporation (product modeltype “HWC­WH6702V”) is installed for this project.
