The principal difference between a heat pump and a refrigerator is a matter of perspective. A heat pump is simply a refrigerator where the inside of the refrigerator is outside the house. In other words, a heat pump attempts to cool down the air outside the building, and in the process heats up the air inside the building.
Heat transfer through the coil wall decreases. The coil area is less if part of the space is occupied by oil. Both of these factors produce a larger temperature difference (TD) between load and evaporating refrigerant. Increased TD in the evaporator indicates a decrease in capacity. Capacity is further reduced to the extent that the vapor pressure of a refrigerant/oil solution is less than
