TRANSIENT MODELING OF TWO-STAGE AND VARIABLE REFRIGERANT FLOW VAPOR COMPRESSION SYSTEMS WITH FROSTING AND DEFROSTING
… framework contains a wide range of components and its modular nature enables an arbitrary cycle configuration to be analyzed. One of the highlights of this framework is the first-principles heat exchanger models with many salient simulation capabilities. Specifically, a high-order discretized …

Impact of heat exchanger surface wettability on condensation, frosting, and defrosting performance under practical testing conditions
Condensation and frost accumulation on aluminum heat exchangers present major challenges for heating, ventilation, air conditioning, and refrigeration (HVAC&R) systems. Both phenomena increase thermal resistance and airflow restriction, which diminish heat transfer, lower system capacity, and drive …

Liquid-infused slippery surfaces for air-conditioning and refrigeration applications
… surfaces to minimize the water retention and enhance thermal-hydraulic performance for air-conditioning and refrigeration (AC&R) applications. The results demonstrate that the LISs has a sliding angle smaller than 5˚ and reduces the water retention ratio after defrosting by more than 75% …

Wetting and frosting/defrosting study on microgrooved surfaces
… drainage. There is increasing interest in understanding and manipulating the effects of surface wettability on the condensation and frosting processes, to minimize condensate retention and frosting penalties, and to promote effective defrosting. In the present study, the effects of microgrooved …
