Abstract:
A latent heat economizing device having a shell forming a chamber, a saturated refrigerant inlet, a liquid refrigerant outlet, a dual air pass and a suction gas pass is provided for installation in the liquid refrigerant line of a refrigeration system prior to an existing liquid sub-cooler upstream from a metering device in the direction of flow. The inlet includes means for distribution of saturated refrigerant evenly over the internal surface area of the chamber to effect heat transfer and removal of the latent heat of condensation from the vapor and sub-cooling of refrigerant liquid. A liquid level is maintained within the shell to effect heat transfer from the liquid to the suction gas pass. The outlet for the liquid is connected to the lowest part of the shell to insure that no vapor is passed through the outlet to the metering device.
