METHOD OF AUTOMATIC CONTROL OF AIR CONDITIONING SYSTEM IN OPTIMAL MODES Russian patent published in 2012 - IPC F24F11/06 

FIELD: ventilation.

SUBSTANCE: based on the measured heat-humidity parameters and the cost of intake outdoor, supply and exhaust air, as well as calculated in the unit of automation and control of heat and humidity release in the premises, area and parameters of air in the test point, the unit operation of automation and control is organised at two levels so that at the first level, the necessary measurement of parameters of intake outdoor, supply and exhaust air is carried out; heat and humidity excesses in the premises are calculated, parameters of air in the test points, the class of heat and humidity loads; zone boundaries of change of the outside air are calculated, and the specific calculated area is defined within which the current parameters of the outside air are located, the checkpoint corresponding to this calculated area is set and then depending on the combination of class of heat and humidity loads and the calculated area, the appropriate operating mode of the air conditioner is set, providing the use of air I and II recirculation by means of connecting the relevant control bodies of devices of heat and humidity air treatment, and at the second level, for the set operating mode of work, the regulation is provided to maintain the set parameters of air in the premises, by affecting the control bodies of devices for air treatment. When the work in automatic mode of maintenance the temperature and humidity mode (THM) in the premise, the optimal energy consumption of different types of energy is achieved. Parameters of the internal air are adjusted with their deviation from the desired values.

EFFECT: use of this method enables to take into account the class of THM and provides for use of air circulation I and II, as well as increases the accuracy of maintained parameters in the premises by means of the control software.
