Abstrakt

Mathematical model of air-conditioning system is based on the analysis of termoekonomicheskom considering energy efficiency, which can be solved in the complex: the determination of optimal parameters; determination of optimal device and optimize refrigeration system operating modes.
It should also be borne in mind that the energy of the refrigeration unit may be transferred in the form of heat and mechanical work in the form of optimal regimes .Research complex optimization termo-economic method using the example of a central air conditioning system and a typical single-stage refrigerating unit
Selected optimization criterion resulted expenses which for this case can be described by the expression, which comprises
 prices for electricity at different rates: the night, peak and semi-peak with an appropriate action time, the volumetric flow of fresh water, gas compressor electromotor exergy, exergy electromotor water pump, fan electromotor exergy; exergy air cooler fan motor; exergy electromotor pump humidifier, standard deduction of depreciation and maintenance costs of individual elements of the gas compressor, condenser, water pump, air cooler fan, humidifier, pump electromotor s humidifier. robochem number of hours per year.
Elaborate a model built with the requirements of the thermo-economy and adequate real vohduha conditioning flowsheet with a refrigeration unit with a view of three-zone fare.
