METHOD AND DEVICE FOR COOL DRYING A GAS

摘要

Method for cool drying gas by means of a cooling element with an evaporator (3) and means for determining the evaporator temperature and for measuring the lowest gas temperature with the following steps: - determining the load of the cooling circuit on the basis of the evaporator temperature and the lowest gas temperature; - calculating a desired value for the evaporator temperature that is required to cool the gas supplied to a set lowest gas temperature, taking account of the aforementioned load; - controlling of the speed of the compressor (4) to make the evaporator temperature equal to the aforementioned desired value.
