Kigali's amendment on Montreal Protocol has recognized the great impact of
hydrofluorocarbons (HFCs) on climate change. In the European Union, the Regulation (EU) …

This paper comprehensively reviews the recent studies on advanced vapor compression
cycle technologies. These technologies are categorized in three groups: subcooling cycles …

Because air conditioning and heat pump systems contribute greatly to greenhouse gas
emissions, equipment with both lower global warming potential (GWP) working fluids and a …

To provide alternative refrigerants for R410A in those applications where the GWP (global
warming potential) limit is extremely restrictive in the medium and long term. This work …

An important step during a project of a heat pump system is choosing a more suitable
refrigerant. This paper presents a comparative study among refrigerants for a small direct …

Refrigerant substitution is an important topic in develo** air-source heat pumps (ASHPs).
The new refrigerants were selected based on their environmental impact indices …

Abstract Life Cycle Climate Performance (LCCP) is a widely accepted metric to evaluate the
carbon footprint of air conditioning (AC) systems “from cradle to grave.” This paper:(1) …

This two-part article explores the dynamic behavior of a flash tank vapor injection heat pump
system from a numerical simulation perspective. Part I provides a first-principles model …

In the present paper, the refrigerant mixture R32/R290 (68%/32% by weight) is investigated
as the drop-in replacement for R410A in household air conditioners. The GWP of it is only …

This review synthesizes the possible lower GWP substitutes for the R-410A refrigerant, since
high GWP HFCs refrigerants are being controlled due to the growing worldwide concern …
