摘要

This paper presents an experimental and theoretical analysis of a 6-row horizontal microfin Heat Pipe Finned Heat Exchanger (HPFHE) used for energy recovery purposes inside an air conditioning unit. The experimental campaign investigated both the summer and the winter conditions for European countries by varying the operating conditions at the inlet of the HPFHE. New experimental tests are presented for the identification of low - global warming potential refrigerants, environmental friendly substitutes of the more traditional HFC134a.The results showed the interesting heat transfer capabilities of HFC152a as an alternative HPFHE working fluid. A simulation model previously developed by present authors was validated against the new experimental data collected and then used to simulate the thermal performance of the HPFHE under different operating test conditions, in order to assess the potentiality of seasonal energy savings with HFC152a.
