FIELD: heating.
SUBSTANCE: invention can be used in cooling towers of industrial facilities and power plants. Method involves installation of capacitive accumulator 5 for water condensate control in closed recirculation loop of cooling tower, formed by cooling tower 1, air treatment device 2, steam and air ducts 3 and condensate pipelines 4, where accumulator for water condensate control serves also for required water volume maintenance in the cooling tower and process water supply system and for primary accumulation of condensation heat; phase accumulator for heat regulation with heat-absorbing material 6 is installed; condensation of steam and air mix is performed in air treatment device on the cooling surface of heat exchange at temperature equal or below dew point; heat exchange surface is formed by one or several consecutive methods: by heat exchange pipes where process fluid is circulating at temperature equal to or below dew point, by refrigeration aggregate operation, by adding cold liquid or solid particles to the steam and air mix, by steam and air mix compression; heat exchange surface is formed by one or several consecutive methods: by heat exchange pipes where process fluid is circulating at temperature equal to or below dew point, by refrigeration aggregate operation, by adding cold liquid or solid particles to the steam and air mix, by steam and air mix compression, so that condensed phase is more stable in thermodynamic sense than gas phase at temperature and pressure obtained; condensation heat from recirculation cycle is accumulated in heat regulation accumulator and fed from it by heat pump 7 to heat consumer at destination place 8; recirculation of steam and air mix and cooled dehydrated air in closed recirculation loop is performed by increasing pressure difference between saturated steam and non-saturated steam in cooled dehydrated air, and forced air feed by suction or forced-draft fan 9; water is cooled below temperature values of wet-bulb thermometer of ambient air, and cooling tower operation depends less on external water source and ambient air conditions; high concentration of heat accumulation is achieved, and excessive air volume is exhausted through control valve 10 and is compensated via inlet valve.
EFFECT: control and maintenance of required water volume in cooling tower and process water supply system.
