1 Urgent Requirements and Project Challenges

As a luxury 5-star beachfront resort and hotel, Radisson Blu Cam Ranh has a huge demand for a stable and continuous cooling source to ensure the highest level of customer experience. The biggest challenge is how to meet this high energy demand while cutting peak-hour electricity operating costs in the most efficient way.

The project's objective is to implement a large capacity cold storage system, perfectly integrated into the technical basement area, to bring double benefits: service stability and financial optimization .

2 Large Capacity TES Solution In Basement

ESS Vietnam has supplied and installed a concrete Cold Storage Tank (TES) solution with a large capacity of 14,700 kWh in the basement of the hotel's technical area .

1. Active Energy Saving: The system is designed to produce and store a huge cooling capacity of 14,700 kWh during off-peak hours (Off-peak, cheap electricity price).

2. 5 Star Operation Guarantee: This reserve cold is then used to supply the entire air conditioning system during peak hours, significantly reducing dependence on the main Chiller system, ensuring cold supply is always available at optimal cost.

3. Strategic Location: Utilize the basement space of the technical area to place a large concrete tank, optimizing the connection with the building's existing mechanical and electrical equipment.

3 Investment Efficiency and Professional Implementation Process

The Radisson Blu Cam Ranh project is proof that the TES solution is the top choice for high-end projects, where stability goes hand in hand with financial efficiency.

• Absolute Financial Efficiency: Although the investment capacity is large, the ability to save electricity costs is very high, leading to a payback period (ROI) of only 3 years . This is the key factor that helps investors make quick decisions.

• Completion Guarantee: The project was completed and installed by ESS Vietnam in September 2018 , ensuring the hotel's completion schedule.

3.1 Cold Storage Tank Installation Process in Basement

The construction process in the basement of the technical area is carried out through detailed and professional steps, ensuring the highest durability and efficiency:

1. Concrete Tank Construction: Start building the reinforced concrete rock storage tank structure in the basement, ensuring waterproofing standards and solid structure.

2. Waterproofing Membrane: Applying a specialized waterproofing membrane inside the tank is an extremely important step to prevent leaks and protect the concrete structure from temperature changes.

3. Heat Exchanger Installation: Carefully install the heat exchangers and main manifold inside the tank. These are the heart of the system, where the freezing/defrosting process (charging/defrosting) takes place. (Figure 3: Heat exchanger installed in the tank, Figure 4: Heat exchanger and main manifold in the tank).
