A technical look at how zeotropic refrigerant blends affect a water-to-water heat pump’s performance.
The report investigates how different refrigerant mixtures perform in a specialized heat pump setup. It explains how glide matching between the heat transfer fluid and the refrigerant influences cooling and heating COP values, and it describes an experimental apparatus designed to measure these effects under controlled conditions. This edition emphasizes practical results and comparative data for both cooling and heating modes.
- How zeotropic mixtures compare to conventional refrigerants in cooling COP and heating COP
- What glide matching means and how it affects heat exchanger performance
- Details of the test setup, including the heat transfer fluid loops and instrumentation
- Observations on how propane (R290) and R32/290 blends perform across capacity ranges
Ideal for engineers, HVAC professionals, and researchers interested in refrigerant blends, system efficiency, and open-loop testing outcomes.
