Chiller plant design calculation: Detailed Cooling Profile Simulation

Less than three decades ago, full load kW/ton was still a widely used metric of chiller efficiency. It was only in the late 1980s that stakeholders in the industry realized that this indication was incomplete because full load conditions are rare in real life situations. That was the beginning of be[..]

Thermal Energy Storage

Tank heater accumulation of thermal energy as supply security systems

During the 1970s and early 1980s, the world witnessed the worst oil crises ever following an oil embargo imposed by producers from the Middle East. Due to power reliability problems that were triggered by these events, chilled water storage systems were born. District cooling itself is a very old te[..]
