Abstract
The invention provides two distinct schematics allowing system performance enhancement through the utilization of an auxiliary heat exchanger and splitting the refrigerant flow into primary and secondary paths. A system performance boost is achieved due to extra subcooling of a primary refrigerant flow in an auxiliary heat exchanger as well as superheat reduction of the combined refrigerant flow entering the compressor and a primary refrigerant flow pressure drop decrease through the evaporator (in comparison to the prior art). The invention offers the superior benefits outlined above with only a moderate cost increment. Also, employment of conventional components only, and no compressor modifications make implementation of the proposed schematics even more attractive.
