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 …

Refrigerant flow distribution in vertical headers of reversible microchannel heat exchangers
… pump mode, it functions as an evaporator and refrigerant maldistribution among parallel microchannel tubes creates unwanted superheated region, which lowers the heat transfer between refrigerant and air. This thesis presents the experimental and modeling study of refrigerant distribution in …
