A vapor compression system (10) including an evaporator (16), a compressor (12), and a condenser (14) interconnected in a closed-loop system. In one embodiment, a multifunctional valve (18) is configured to receive a liquefied heat transfer fluid from the condenser (14) and a hot vapor from the compressor (12). A saturated vapor line (28) connects the outlet of the evaporator (16) and is sized so as to substantially convert the heat transfer fluid exiting the multifunctional valve (18) into a saturated vapor prior to delivery to the evaporator (16). The multifunctional valve (18) regulates the flow of heat transfer fluid by monitoring the temperature of the heat transfer fluid returning to the compressor (12) through a suction line (30) coupling the evaporator (16) outlet to the compressor (12) inlet. In one preferred embodiment, a bifurcated liquid line connects the condenser (14) outlet to the first inlet of an multifunctional valve and the inlet of a metering unit.

1. A device for coalescing the liquid present in a liquid vapor mixture, the device comprising:a device inlet; a device outlet; and a common chamber connected to the device inlet and the device outlet, wherein the liquid vapor mixture flows through the common chamber from the device inlet to the device outlet in a flow direction, the common chamber having a first portion upon which the liquid vapor mixture flows through upon entering the common chamber from the device inlet, the first portion connected with the device inlet and the device outlet, and a second portion adjacent the first portion and connected to the device inlet and device outlet only through the first portion, wherein a portion of the liquid within the liquid vapor mixture coalesces within the second portion and wherein the liquid vapor mixture exits the common chamber by the device outlet as a liquid and a vapor having a substantial amount of the liquid separate and apart from a substantial amount of the vapor. 2. The device of claim 1, the common chamber having a width greater than the width of the device inlet or the device outlet.3. The device of claim 1, wherein the general path from the device inlet to the device outlet defines a flow direction, and wherein the second portion is located away from the flow direction, so that the liquid may coalesce in the second portion.4. The device of claim 1, the device further comprising a metering unit positioned adjacent to the device inlet, the metering unit having a valve assembly for regulating the flow of liquefied heat transfer fluid into the common chamber.5. The device of claim 1, the device further comprising a second device inlet coupled to the common chamber, wherein the second device inlet is configured to receive a high pressure vapor and transfer the high pressure vapor to the common chamber.6. The device of claim 1, wherein the liquid vapor mixture is in a turbulent state upon entering the device inlet, so that a portion of the vapor within the liquid vapor mixture gets trapped in the second portion.7. The device of claim 1, wherein a vortex is formed in the common chamber.8. The device of claim 1, further comprising a metering unit coupled to the device inlet, the metering unit volumetrically expanding the heat transfer fluid into the common chamber.9. The device of claim 1, further comprising a reservoir within the second portion, wherein the reservoir traps a portion of the heat transfer fluid within the common chamber, allowing the liquid to coalesce.10. The device of claim 1, further comprising a notch adjacent the outlet, wherein the notch reduces the amount of heat transfer fluid that can exit the common chamber through the device outlet.11. The device of claim 1, further comprising a second device inlet providing fluid ingress for a hot gas to enter the common chamber.12. The device of claim 1, wherein the heat transfer fluid is in a turbulent state upon entering the inlet.13. The device of claim 1, wherein an eddy is formed in the second portion.14. The device of claim 1, wherein a vortex is formed in the second portion.15. The device of claim 1, wherein the device forms part of a multifunctional valve for generating a heat transfer fluid wherein a substantial amount of liquid is separate and apart from a substantial amount of vapor.16. The device of claim 1, wherein the first portion has a length equal to no more than 75% of the length of the common chamber.17. The device of claim 16, wherein the first portion has a length equal to no more than 35% of the length of the common chamber.18. A valve comprising a XDX valve having a first inlet and an outlet, and the device of claim 1, wherein the device inlet is in flow communication with the first inlet of the XDX valve and the device outlet is in flow communication with the outlet of the XDX valve.
