Study of Water-cooled Auto-cascade Refrigeration Cycle with a Low Temperature of﹣60 ℃

open access: yesZhileng xuebao, 2015
A new water-cooled auto-cascade refrigeration cycle(WACR) using a binary refrigerant mixture is presented, which adopts a condenser-phase separator instead of a condenser and an evaporative separator in traditional auto-cascade refrigeration cycle.

A calibration method for SWMM to mitigate the impact of the structure defect without considering runoff on building walls

open access: yesFrontiers in Ecology and Evolution, 2023
In this study, we propose a hypothesis that an automatic calibration framework can address modeling uncertainties in the Storm Water Management Model (SWMM) due to structural defects that result in the inability of the model to account for runoff ...
