High Efficiency Refrigerants for Heat Pumps

Detailed overview of innovation with sample startups and prominent university research


What it is

High-efficiency refrigerants are fluids used in heat pumps and refrigeration systems that offer improved thermodynamic properties and lower environmental impact compared to traditional refrigerants. These refrigerants are designed to enhance energy efficiency, reduce greenhouse gas emissions, and minimize ozone depletion potential.

Impact on climate action

High-Efficiency Refrigerants within Heat Pumps advance climate action by reducing greenhouse gas emissions and enhancing energy efficiency. By replacing potent greenhouse gases with low-global warming potential alternatives, these innovations mitigate climate change impacts, improve indoor air quality, and promote the adoption of eco-friendly heating and cooling technologies.

Underlying
Technology

  • Thermodynamic Properties: High-efficiency refrigerants possess superior thermodynamic properties, such as high heat transfer coefficients and low pressure drops, which improve the efficiency of heat pumps and refrigeration systems.
  • Environmental Impact: Traditional refrigerants, such as chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), have been phased out due to their ozone depletion potential and high global warming potential (GWP). High-efficiency refrigerants are designed to have low or zero ozone depletion potential and significantly lower GWP.
  • Safety Considerations: Refrigerants must be non-toxic, non-flammable, and chemically stable to ensure safe operation in heat pumps and refrigeration systems.
