Abstract

The paper presents a theoretical analysis of the effect of electric car performance characteristics on vehicle energy consumption and driving range. The test object was a Nissan Leaf electric vehicle. The characteristic curves of basic and additional resistance to motion (sum of rolling resistance and air resistance and inertia resistance or grade resistance, respectively) were applied to the model characteristic curve of electric motor torque of the tested vehicle. Based on that, the graphs describing the relationships between vehicle energy consumption and vehicle speed were made (for specific values of car acceleration / acclivity grade) as well as the relations between vehicle driving range and its traction properties. It was concluded that the use of performance characteristics significantly increased the vehicle’s energy consumption and decreased the available vehicle’s driving range.

Abstract

The paper presents the simulation analysis determining the effect of tyre energy efficiency class on fuel consumption of a passenger car. Calculations were made assuming the wheel movement on a dry and smooth asphalt road surface. The tests based on a simulation model were performed on 61 types of tyres, being characterised by different sizes and energy efficiency classes. Different values of rolling resistance coefficient were adopted (in accordance with energy efficiency classes), also, the values of basic and additional resistance to motion were determined. Based on them, engine speeds and load torque corresponding to respective specific fuel consumption were estimated. This parameter allowed the relationship between average mileage fuel consumption and tyre energy efficiency class to be determined on the basis of the NEDC test.

Abstract

The paper presents the problem of intelligent installations in buildings, their construction and integration with other systems present in the building. Attention has been focused on systems designed to ensure the safety of property and persons residing in different facilities. It also discusses ways to control the microclimate and other aspects of the building so as to obtain the maximum comfort of the people placed in them. Considering its high popularity, the smart installation based on the KNX/EIB standard is further discussed, examples of algorithms for dealing with security threats are given as well as the functions indicated which can improve the comfort of using a facility.

Abstract

The paper presents the results of laboratory tests concerning the cutting process of basket willow by means of disc cutting unit. A disc for cutting wood with diameter of 600mm was used in the tests. The influence of plant’s moisture and the rotary speed of the disc of cutting unit on the unitary energy were determined. The most favorable values of the operating parameters of the cutting unit were selected according to the minimum energy requirement in the cutting process of the tested plant.

Abstract

This paper presents the results of measurements of the operation of a photovoltaic system, connected to the power grid. The intensity of solar radiation and the ambient temperature in the location of the installation were simultaneously recorded in different weather conditions on selected days throughout the year. For the combined results the analysis of correlation in terms of efficiency of individual exemplary photovoltaic installation was conducted.

Abstract

The paper presents selected issues relating to the energy analysis of the air heat pump for hot water. Experimental studies on a test stand made it possible to verify the operational parameters of the heat pump under actual conditions of use. The study shows that heating the water in the storage tank with the capacity of 130 dm3 from 25°C to 40°C took approximately 60 minutes and the water heating for another 5°C took 30 minutes longer. The heat pump process in the field of higher water temperature in the tank is less effective, thus heating the water in the tank above 50°C is less favorable economically.

Abstract

The article focuses on selected aspects of the technical and economic analysis of the 0.8 MW agricultural biogas plant. The electrical power, generated in a cogeneration system, fed power to the neighbouring overhead power grid, Węgrów – Sokołów Podlaski, while the heat energy recovered from combustion gases and liquids cooling the engine was used to heat digesters, a residential building, drying room and farm buildings. The planned annual production equals c.a. 6400 MWh per year given the 8000 h of engine operation. The substrates used as input for the digestive chambers were as follows: fermented maize, pig slurry and liquid digestate pulp.

Abstract

This paper shall present and explain the key aspects related to the issue of combined heat and power generation (CHP – Combined Heat and Power or Cogeneration). The cooperation with the water treatment plant launched allowed a closer look at the described technology as well as allowed the analyses and survey. The survey on the efficacy of the selected components of the cogeneration system was based on two cogeneration units fuelled with biogas produced in the sewage fermentation.

Abstract

This work analyzes the process of construction and manufacturing of a blade used in a wind turbine. The calculation scheme is presented for forces generated on the blade of a wind turbine and parameters are determined of weather conditions in which the designed element would be working. Subsequently, for the chosen aerodynamic profile the characteristics are calculated of its aerodynamic coefficients, which enables the establishing of the angle of attack which impacts the yield of wind engines. The presented process is an introduction to 3D modelling of a wind turbine’s blade and simulation of its creation in a CAM environment.
