Abstract

Next generation of refrigerants require drastically lower global warming potential (GWP). The refrigerant mixtures, with a GWP 9.5 (heating seasonal COP of 2.78). The unit was tested in an extensive ambient condition, heating operation from 5ËšF to 62ËšF (-15ËšC to 16.7ËšC); cooling operation from 82ËšF to 95ËšF (27.8ËšC to 35ËšC). The paper will introduce the system configuration, heat exchanger dimensions and laboratory investigations.
