A condensate retaining apparatus for use with a refrigeration heat exchanger having at least two plannar slabs mounted in an air duct. Each slab has an upper and lower end and forms an oblique angle with respect to the direction of air flow and further includes a coil for conducting a fluid and a plurality of form defining channels for conducting condensate toward the lower end of the slab. The slabs are mounted so that the lower end of each overlying slab is offset inwardly from the upper end of the nearest underlying slab with each pair of adjacent slab ends defining an apex of the heat exchanger. The apex is covered to prevent condensate from being entrained in that air flow and as well as being shielded from the air flow.

To prevent refrigerant leakage when operating in a metering mode, a refrigerant expansion device, designed to selectively operate in either the meteting or bypass mode of operation, has a cylindrical ring installed to tightly hold the meteting piston in its metering position so as to prevent leakage ofrefrigerant therearound.
