• From the turn of the 19th century to 1991, Subic grew from a Spanish naval facility to the largest U.S. military naval base in Asia.
• In 1991, after the volcanic eruption of Mt. Pinatubo, Subic was returned to the Philippine government and then developed into the Subic Bay Freeport Zone (SBFZ).
• In 1993, Royal Duty Free Shops opened its doors to customers hungry for imported products and for premium imported goods previously unavailable to the average Filipino.

CCI-Hub Technical Training Workshop | October 7, 2020
• Why renovate ROYAL 1?• It’s a 26 year old store, inside a 50 year old building,
with 11-15 year old Refrigeration system• Cold rooms are over 40 years and were
used by the Americans
• Status of present refrigeration• All Store refrigeration are Stand alone producing
heat inside the store.• Frequent breakdown of units due to high pressure
as a result of the heat emitted.• Inefficient air-conditioning system• High maintenance vost

Installation ProcessCharging of R290 refrigerant
Proper Handling of Refrigerant
• Ensure good room ventilation at floor level. • Use only grounded apparatus.• Take measures against electrostatic charge.• Keep vessels away from electric devices, sparks, heat sources, and open light. • Safety shoes, antistatic and non-combustible clothes, protective gloves and eye
goggles are to be provided for every person concerned with maintenance, repair and recovery
• Do not add anything to the Refrigeration System except Flushing Agent, Nitrogen, R290 and Refrigerant Oil.

Installation ProcessMaintenance Of R290 refrigerant system
The System uses a completely Hermetic Compressor with 150 grams of R290 Refrigerant charge per system.
No change oil needed for every Preventive Maintenance Schedule (PMS), which makes it more cost efficient on the client’s end.
There will be monthly spring-cleaning, which is essential in every Refrigeration cabinet and is required for sanitation purposes – regardless of the refrigerant used.

Installation ProcessMaintenance Of R290 refrigerant system
Electrical Re-Torque is required to prevent loose connections that may cause fire. The system is R290, which is a propane based refrigerant and is flammable.
Flameless reparation is recommended for the system using the Crimping Tools and Copper Tube.
R290 Refrigerant System and Conventional Refrigerant System have similar maintenance standards. However, the preparation and maintenance of the R290 Refrigerant System requires competitive knowledge of the system to successfully
undergo procedures and prevent incidents that may lead to system failure of equipment.

CO2 Transcritical vs Subcritical
CCI-Hub Technical Training Workshop | October 7, 2020
What is the difference?
• Subcritical• Operate below critical point
• Transcritical• Operate above critical point
• TC system will operate in SC manner most of the time• Depend on ambient
![Page 92: Technical Training Workshop | Advanced Technologies for](https://reader034.vdocument.in/reader034/viewer/2022051813/6282be284c45d24f680da706/html5/thumbnails/92.jpg)
CO2 Transcritical Operation
• No Pressure-Temperature Correlation• Do not condense, no phase change• Gradual temperature loss• Closer approach to air
• SC: 5 to 8’C• TC: 2’C
• Improved heat rejection
Any benefits?

CO2 Transcritical System
• High Pressure Control• High pressure valve to control discharge
pressure• Control according to ambient • Optimum efficiency
• Flash Gas Control• Flash gas valve to control receiver
pressure• The higher the pressure the more FG• FG focus of most efficiency improvement
