We well know that micro channel heat exchanger is more effective for a performance enhancement than Fin & Tube heat exchanger in Chiller applications and it helps to reduce refrigerant quantities in the systems. In Heat Pump applications, on the other hand, the outdoor unit is normally subjected to the frost / defrost issue when the ambient temperature approaches the 0 °C and this aspect challenges the MCHE usage.

This presentation shows the results of a study where we tested a new MPE tube for Micro Channel Heat Exchanger installed on Air-cooled Heat Pump, a typically modular version of commercial size. Aim of the study was to reach a frosting time o ...
