Analysis of factors determining operability of air conditioning system of transport and technological vehicles
Abstract
The article analyzes the factors influencing the performance of the air conditioning system of transport and technological vehicles. The values of possible refrigerant leaks in the air conditioning system are analyzed and calculated. The joints that make the greatest contribution to refrigerant leakage have been identified.
Traditional and neural network methods of forecasting electricity consumption: an overview
Abstract
The paper provides an overview of traditional and neural network methods for forecasting electricity consumption. A medium-term forecast of electric energy consumption in a 0.4 kV distribution power grid using the statistical forecasting method and the simplest neural network is presented. The analysis of the results showed that the trained neural network produces a more accurate result compared to the statistical forecast.

Development of control system for operation modes of the Himmash boiler house
Abstract
The article presents an analysis of the factors that have the greatest impact on the consumption of electricity by a boiler house. To reduce the impact, a thermal scheme of a hot water temperature control system and a scheme of a hot water metering unit with additional equipment are proposed. When implementing the proposed measures, the consumption of electricity will decrease by more than two times, the fuel consumption will decrease by 10-15 kg of cu/ Gcal.
