SINTEF researcher proposes replacing glycol circuit with water/ice cold thermal energy storage, combined with transcritical CO2 refrigeration.
The TRI-HP Project finds CO2-ice heat pump perfoms with higher COP at lower compressor speed.
Particle sensors require temperatures of -60C to -80C.
Italian researchers determine that R744 unit outperformed the R134a unit during the hottest months of the year .
The proposed system uses a multi-ejector, parallel compression and mechanical subcooling.
The algorithm is designed to deliver enhanced efficiency and performance
The system is designed to provide dehumidification in low-temperature environments without the risk of freezing
There are few ice slurry systems that utilize ammonia or CO2, says SINTEF scientist Widell.
Their efficiency comes from increased suction vapor density, which is a significant advantage in colder climates, says NTNU researcher
