| Abstract: | A steady-state model of air-cooled heat pump chiller is established.The experimental validation is made in cooling and heating models. The results of simulation are in good agreement with that of the experiment. The experimental results show that the refrigerant flow at the condenser outlet can be super cooled in super cooled sect heat exchanger with reasonable design and the super cooled sect heat exchanger can also thaw the ice at the bottom of wavy finned tube heat exchanger in cooling model. |
