... capacity of the heat pump. In order to improve the problem of uneven frost along the airflow direction in the evaporator, an experimental study is conducted on the frosting and heat transfer performance of three rows of variable pitch (VP) finned coils in different fin pitch combinations under low ambient...

...; published online September 11, 2013. Assoc. Editor: Roy E. Hogan. 08 07 2012 14 03 2013 Loop heat pipes (LHP) are heat transfer devices which use evaporation and condensation of working fluid to transfer heat and use capillary forces to provide fluid circulation in a closed loop. One...

... recently developed [ 5 ], the harshest possible transient change scenarios have been simulated. The rise time of the condenser and evaporator pressures were found to be around 2–3 s. By considering ten samples within the rise time, the sampling frequency is at least 5 Hz. The AST4000-AV-0250-P4E-1000...

...Ling-Xiao Zhao; Liang Yang; Chun-Lu Zhang A new neural network modeling approach to the evaporator performance under dry and wet conditions has been developed. Not only the total cooling capacity but also the sensible heat ratio and pressure drops on both air and refrigerant sides are modeled...
