Study of energy consumption by heating and air-conditioning systems of a class I vehicle with electric traction unit

P. Godovanyuk Ihor Budnychenko A. A. М. Kosharny

This scientific article elaborates theoretical material on the topic: Study of energy consumption by heating and air conditioning systems of a class I vehicle with an electric traction unit", the share of energy consumption that falls on heating and air conditioning systems in the total amount of energy consumption for the own needs of a class I vehicle is determined And with an electric traction unit and the distribution laws of these quantities. The object of the study is "Bohdan" type T70117 trolleybuses operated in Vinnytsia. . The purpose of the work is to determine the share of energy consumption by passenger and driver comfort systems in the total amount of expenses for own needs of a Class I vehicle with an electric traction unit. The research method is to estimate the share of energy consumption for own needs, which was organized by observing the readings of direct current meters installed on 12-meter trolleybuses of the "Bogdan" type T70117 operated in the city of Vinnytsia. According to the received data, in relation to the readings of the virtual counters, which are presented in the tables, the energy consumption for the own needs of 12-meter trolleybuses of the "Bogdan" type T70117 was calculated. As a result of the study, it was determined that energy costs for powering the vehicle's own needs, systems that ensure the comfort of passengers and the driver, as well as their shares in the total costs for powering own needs are subject to the normal law of distribution. The share of energy consumption for powering passenger and driver comfort systems is on average 57% of the total amount of energy consumed for the own needs of a class I vehicle with an electric traction unit and can reach 85%. A significant share of the costs of powering systems that ensure the comfort of passengers and the driver should contribute to the implementation of research and development based on their results of energy efficient systems to ensure the comfort of passengers and the driver.
