Transient distribution of refrigerant and oil in a residential heat pump water heater system
In most vapor-compression refrigeration systems, oil is added into the compressor for lubrication. However, it is inevitable that a portion of oil escapes from the compressor and circulates throughout the system due to the mutual solubility between the refrigerant and oil. The presence of …

Investigation of oil retention and pressure drop in suction lines using R1234yf, R134a and R410A with POE ISO 100
Compressors of typical vapor compression refrigeration systems require the presence of oil, primarily for the purpose of lubrication. A small portion of this oil is transported out of the compressor by the high velocity refrigerant vapor exiting the compressor or by the refrigerant forming an …

A quasi-steady modeling approach of a heat pump water heater system with experimental validation and analysis
… system, the dynamic interdependence between the vapor compression system and the water in the storage tank poses a modeling challenge for steady-state refrigeration system models. The aim of this project is to develop a model and methodology for coupling steady-state vapor compression system …
