Patent ID: 7017365

Claim:
A system for dehumidification in air conditioners, comprising an expansion stage, a condenser, and a water separator upstream of the expansion stage, wherein the condenser is formed by a heat exchanger (RAM CON) cooled by ambient air or stagnation air or another fluid, with the exception of process air, to which the compressed air to be dehumidified is supplied, the heat exchanger is a RAM heat exchanger, and (i) the RAM heat exchanger (RAM CON) is divided into two and the heat exchanger region facing the outlet side on the compressed air side is acted upon by air or another fluid whose temperature is under the ambient air temperature or stagnation air temperature, or (ii) a bypass which can be closed by a valve (ATV) and which bypasses the water separator (WE) is provided which is in communication with the inlet of the expansion unit.
