Indoor Liquid/Suction Heat Exchanger

摘要

Systems and methods are disclosed that include providing an air conditioning (A/C) system having an indoor unit with a Liquid/Suction Heat Exchanger (LSHX) coupled between an outdoor heat exchanger of an outdoor unit and an indoor metering device on a so-called “liquid” line and coupled between an indoor heat exchanger and a compressor of the outdoor unit on a so-called “vapor” line. The LSHX is configured to increase the efficiency of the A/C system by increasing the amount of subcooling in the refrigerant on the liquid line of the LSHX and increasing the amount of superheat in the refrigerant on the vapor line of the LSHX.
