Résumé

The mathematical model of the air conditioning system is based on the analysis of thermoeconomic indications of energy efficiency, which can be solved in complex: the determination of optimal parameters; determining the optimal device and optimization of operating modes of the refrigeration system.
The model takes into account that the energy of the refrigeration unit may be transmitted in the form of heat and mechanical work under optimum conditions of the compressor. On the basis of the analysis carried out termoekonomicheskogo optimization of central air-conditioning system and a typical single-stage refrigeration system.
The resulting optimization criterion resulted in costs that are described by an expression that includes prices for electricity with different loads: night, peak and half peak, fresh water volume flow, exergy of the gas compressor motor, water pump and electromechanical fan, air cooler fan motor, humidifier motor, Depreciation and operating costs of individual elements of the compressor, condenser, water pump, air cooler fan, humidifier, electric pump ktromotora with a humidifier to the number of hours of work per year. The developed model, built taking into account the requirements of thermo-economics and an adequate real air-conditioning scheme with a refrigeration unit, taking into account the three-zone payment for electricity.
