Working Fluids for High-Temperature Heat Pumps

Optimize Waste Heat Recovery with High-Performance Working Fluids

High-temperature heat pumps (HTHP) can be used to recover waste heat and provide heating for industrial processes like drying, sterilization, paper making, and food preparation. These HTHPs work differently from air conditioners by recovering waste heat energy and converting it to reach the same or higher temperature as conventional gas boilers. The recovered heat can then be efficiently repurposed for several applications, including:

  • District heating
  • Secondary fluids heating
  • Steam generation
  • Evaporation and distillation

Selecting the best working fluid for HTHPs is important. Because HTHPs typically provide heat at temperatures between 100 and 160 °C (212 to 320 °F), some working fluids appropriate for low- and medium-temperature heat pumps are less effective. HTHP working fluids also need thermal stability, heating performance, pressure, enthalpy, and vapor characteristics appropriate for their intended application and use.

Energy Efficiency and Environmental Sustainability

Opteon™ MZ working fluid is a zero ozone depletion potential (ODP), low global warming potential (GWP) fluid that provides the best balance of properties and performance for HTHPs. It enables HTHP operators to improve overall energy efficiency in industrial operations by recovering waste heat that would normally be released into the atmosphere.
