Vapor compression heat pumps with pure Low-GWP refrigerants

Renewable and Sustainable Energy Reviews, 2021
Abstract Global warming is a major environmental concern, which significantly impacts ecological systems and the safety of coastal cities. To address global warming, effective methods must be adopted to reduce greenhouse gas emissions and the consumption of fossil fuels. Vapor compression heat pumps offer an effective way to recover energy from waste

Thermodynamic Properties of Refrigerants with Low GWP

2017
Since the discovery in the 1970s of the stratospheric ozone depletion and the role of chlorinated compounds in this harmful event, the world of refrigeration has undertaken a change process still under way. After the progressive substitution of chlorofluorocarbons and hydrochlorofluorocarbons with nonchlorinated hydrofluorocarbons and natural fluids ...

Boiling Heat Transfer of Low GWP Refrigerants: A Review

Journal of Mechanical Engineering: Prakash, 2022
The boiling heat transfer of low GWP (global warming potential) refrigerants, which are more environmentally benign, is studied in this work. Low GWP applications allow for greater freedom in the choice of suitable working fluids based on application and necessity.

Nonflammable Low GWP Working Fluid for Organic Rankine Cycles

Volume 3B: Oil and Gas Applications; Organic Rankine Cycle Power Systems; Supercritical CO2 Power Cycles; Wind Energy, 2014
Regulatory pressure has been increasing globally to address the issue of climate change. In particular, there are plans to reduce the use of hydrofluorocarbon (HFC) based working fluids across many applications, as HFCs are forecast to be significant contributors to global warming in the future.
