Developing condensing-frosting performance maps for a variable speed air source heat pump (ASHP) for frosting suppression
Liu, Shengnan; Xiaoxia, Bai; Long, Zhang; Yao, Lin; Shiming, Deng; Wei, Wang... more authors ... less authors ( Elsevier Ltd , 2022 , Article)For a space heating ASHP unit, frosting on its outdoor coil would adversely impact its normal operation, requiring frequent defrosting and resulting in low operating efficiency and poor indoor thermal comfort. It has been ... -
An experimental study on achieving even-frosting for an air source heat pump using a novel dual-fan outdoor coil
Bai, Xiaoxia; Liu, Shengnan; Deng, Shiming; Zhang, Long; Wei, Minchen ( Elsevier Ltd , 2022 , Article)Many related studies suggested that a fixed airflow direction usually led to that the most frost would only deposit on the windward side of finned tube heat exchangers (FTHXs) of the traditional single fan outdoor coils ...
