title: Molecular Dynamics Simulations of Ubiquitin K11 Mutants

description: This dataset contains trajectory data of the protein ubiquitin with different amino acid mutations at position 11. The variants present in this dataset are wt, K11R, K11Q, K11C, and K11Ac (where the epsilon amino acid of lysine is acetylated). For each variant there are 3 replicate simulations with 200 ns simulated time and time steps of 50 ps. Simulations were performed using the GROMACS simulation package version 2018 and version 2020 and the GROMOS 54a7 force field.

description: This study evaluates a transcritical CO₂ vapor-compression refrigeration cycle of R744 with an internal heat exchanger (IHX) using Simscape and Simulink, under conditions closely representing real-world environments. The analysis considers three key thermal boundary parameters: ambient temperature, refrigerant superheat, and initial IHX pressures. Three simulation scenarios were conducted using outdoor temperature data from Seoul, superheat variation from 3 °C to 15 °C at a constant 35 °C ambient condition, and systematic changes to high- and low-side IHX pressures. Results show that rising ambient temperature increases refrigerant flow and cooling capacity but significantly reduces COP from 9.8 to 2 due to higher compressor power. While elevated superheat prevents liquid carryover, it leads to reduced efficiency. An optimal high-side pressure range of 10–12 MPa is identified. Unlike prior studies focused on steady-state conditions, this work emphasizes dynamic performance using real climate data. The findings offer practical insights into efficient system operation in warm climates and contribute to the development of climate-resilient refrigeration strategies, supporting future research in experimental validation and AI-driven control.
