METHOD AND DEVICE FOR COOL DRYING A GAS

摘要

A method for cool drying gas by a cooling element with an evaporator, using a device for determining the evaporator temperature and measuring the lowest gas temperature, by applying the 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 the speed of the compressor to make the evaporator temperature equal to the desired value.
