Analysis the characteristics of R1234yf, R1234ze, R134a on reefer container
IOP Conference Series: Earth and Environmental Science, 2020 Abstract In this work, the characteristics of R1234yf, R1234ze, R134a on reefer container were studied. According to pressure enthalpy (p-h) diagram, a computer code developed by Matlab was used to calculate power consumption, coefficient of performance (COP), compression ratio, discharge temperature, etc.

Gallate and Indate Salts with Unsaturated Electron Withdrawing Groups
European Journal of Inorganic Chemistry, Volume 27, Issue 5, February 12, 2024.A host of perfluorinated unsaturated electron withdrawing groups are introduced to gallium and indium in the form of novel gallate and indate salts. These gallates and indates constitute an important first step for future investigations into the respective strong Lewis acids.

Performance of Heat Pump Air Conditioning with R1234ze (HFO) as a Refrigerant
Journal of Optimization, Volume 2024, Issue 1, 2024.The study shows that refrigerants R1234ze (E) and R1234ze (Z), known for their low global warming potential, are likely to become primary choices in heat pump air conditioning for residential and commercial use. The research evaluates the thermodynamic properties of R1234ze (Z) using experimental, thermodynamic, and numerical analyses.
