Abstract
A method for cool drying gas, making use of a heat exchanger whose primary section forms the evaporator of a cooling circuit with a compressor, an expansion valve and a bypass pipe across the compressor with a hot gas bypass valve, whereby the method makes use of a formula that makes the link between the state of the expansion valve and hot gas bypass valve, whereby on the basis of this formula: either the state of the expansion valve is adjusted as a function of the state of the hot gas bypass valve; or adjusting the state of the hot gas bypass valve as a function of the state of the expansion valve or vice versa; or the states of both valves are controlled with respect to one another.
