What Is a Seawater Heat Exchanger and How Does It Work in Data Centers?

What Is a Seawater Heat Exchanger and How Does It Work in Data Centers? As data centers continue to grow in size and power density, cooling has become one of the most critical—and costly—operational challenges. Traditional air-cooled and freshwater-based systems are increasingly strained by energy demands, water scarcity, and sustainability goals. This has led many […]

Isotherm Ultra Low Charge “SX” Evaporator Installed at a Rink Facility

Isotherm Ultra Low Charge “SX” Evaporator was installed at a rink facility in British Columbia in 2019 to replace a conventional flooded evaporator. After installation, it was confirmed that the new “SX” Chiller required only 50 lbs. of ammonia, while the 15-year-old flooded chiller that was removed held approximately 1500 lbs. of ammonia.  The “SX” […]

Does Annular Flow Boiling Inside a Tube improve Heat Exchanger Performance?

Does Annular Flow Boiling Inside a Tube improve Heat Exchanger Performance? Vast literature is available about two-phase flow boiling in horizontal round tubes in heat exchangers. Several studies on flow pattern and mapping are also available. However, limited literature is available about two-phase flow in small cylindrical annular passages. A detailed experimental study was conducted […]

Why does Carbon Dioxide (CO2) stand out in a DX Heat Exchanger in low temperature systems?

Why does Carbon Dioxide (CO2) stand out in a DX Heat Exchanger in low temperature systems? Since the Kigali Amendment of Montreal Protocol in 2016, the world refrigeration community has been looking more into the natural refrigerant route. The Kigali Amendment calls for the phase out of Hydrofluorocarbons (HFC) as follows: Developed countries: 10% reduction […]
