Abstract

In this work, a residential air conditioning compressor designed for vapor injection has been modified in order to inject large quantities of oil into the working chamber in order to approach an isothermal compression process. For a range of different oil injection scenarios, the result is a monotonic decrease in compressor discharge temperature as the oil injection rate is increased. In addition, the pumped refrigerant mass flow rate tends to increase as the oil injection rate is increased.
