Abstract
Method for cool drying gas, whereby the cool dryer is characterized by curves that show the setpoint for the evaporator temperature or evaporator pressure for a load as a function of the lowest gas temperature, whereby the method comprises the following steps:—the determination of a curve and Tset or pset as a function of the load that is required to cool the gas to LATset; the control of a supply of coolant from the compressor to an injection point (P) downstream from the expansion means and upstream from the compressor in order to make the evaporator temperature or evaporator pressure equal to Tset or pset.
