Vapor compression system and method

A method of generating a heat transfer fluid, for absorbing heat, comprising:

• providing an expansion valve comprising an inlet providing fluid ingress for the heat transfer fluid to a common chamber, the common chamber comprising a first portion adjacent to a second portion, wherein the first portion comprises the inlet and an outlet and the second portion comprises a back wall opposed to the outlet;
• providing a compressor to compress the heat transfer fluid to a relatively high temperature and pressure and flowing the heat transfer fluid through a first discharge line to a condenser and through a second discharge line to the expansion valve, wherein the outlet of said expansion valve provides fluid egress for the heat transfer fluid from the common chamber to a saturated vapor line and a substantial amount of heat transfer fluid liquid is separated from a substantial amount of heat transfer fluid vapor prior to exiting the common chamber and entering the saturated vapor line;
• flowing the liquid and vapor portions of the heat transfer fluid through a saturated vapor line to an evaporator, wherein heat is transferred to the heat transfer fluid as more of the liquid portion of the heat transfer portion is converted to the vapor portion;
• and
• returning the heat transfer fluid to the compressor through a suction line.
