Abstract:
In an air conditioning system comprising a compressor, a condenser, and an evaporator, the process comprising the steps of:feeding discharged refrigerant from said compressor to said condenser so as to provide a condensed refrigerant flow; splitting said condensed refrigerant flow into a main flow and an auxiliary flow wherein said auxiliary flow comprises between about 8 and about 12% wt. of total mass flow rate of said condensed refrigerant flow; reducing temperature and pressure of said auxiliary flow so as to provide an economizer flow; passing said economizer flow and said main flow through a heat exchanger so as to provide a sub-cooled main flow and an economizer discharge flow; feeding said economizer discharge flow to said compressor; and feeding said sub-cooled main flow through said evaporator to said compressor.
