Energy consumption all over the world is constantly growing. To save energy, new technologies are being developed for the efficient use of energy resources. The goal of all new developments is to use less energy to provide the same level of energy supply for technological processes or buildings. The problem of energy saving is relevant for the ventilation system. Together with the removed air, a large amount of heat is lost, which is not advisable. In order to avoid these losses, heat recuperators began to be used, heating the cold supply air due to the warm air removed from the room. This development belongs to the field of energy saving. The goal is to increase efficiency by reheating the air after the heater with the help of a recuperator for a given temperature difference in the supply air before and after the recuperative heat exchanger. The development is a design of a ventilation unit with air removal and supply air ducts, combined into one housing with a separate, according to the “screw” principle, heat transfer wall, for use in the ventilation system in order to ensure an optimal microclimate in the room. Thus, as a result of using the presented device, the efficiency of the room ventilation unit is increased by reducing the energy consumption for heating the supply air with a heater.

In order to study the energy consumption feature when cornering for motorized wheels driving vehicles, the resistance force on the driving axle was analyzed. A creative method quasi-neutral steering was proposed for vehicle cornering. A motorized wheels driving vehicle model was established, and the simulation of constant speed cornering was performed when the yaw rate as the parameter to control the front-rear torque distribution and the lateral acceleration as the parameter to control the left-right torque distribution. The results indicate that no wheel slipping is happened when quasi-neutral steering. The torque on the rear outer wheel is more than other wheels, and the torque on the outer wheels is more than inner wheels. The power consumption decreases 1.15% by quasi-neutral steering.

Variable speed drive (VSD) is used not only for controlling the speed but also for saving the electric energyconsumption. In this research VSD is applied to 3 phase squirrel cage induction motor used for water pumping inthe industry. VSD is needed to be applied to induction motors because these motors are the largest electricconsumed. Measurement and calculation are performed in the two conditions, before and after attaching VSD inthe motor. Electric quantities are obtained by measurement in the input and in the output of VSD. While energyconsumption and consumption cost are obtained by calculation. Finally, calculation of energy saving and costsaving are perfomed by comparing those two conditions. Aplication of VSD in the induction motor has advantagesfor saving electric energy consumption dan making it last longer. The energy saving and cost saving per year result1.003.984,8 kWh and IDR 732.908.904 respectlively. The longer life is caused by reduction of energy consumption.

The Cost

While home energy prices keep rising, homeowners nowadays are searching for the right options to reduce their electricity bills. Besides, the increase in power consumption can contribute to environmental pollution. Therefore, the proper management of energy in the domestic sector is a vital element for creating a sustainable environment and cost reduction. In this study, the most domestic household appliances consumption of energy are modelled and analysed using the fuzzy logic controller (FLC) in order to permit the home energy management system (HEMS) to perform energy utilization estimation and cost analysis. These appliances are the heating ventilation and air conditioning (HVAC), electric water heater (EWH), and lighting, respectively. The developed system can help to analyse the appliances’ energy consumption and cost sceneries during peak and off-peak hours. The modelling of a fuzzy-based domestic appliances controller for HEMS takes the peak and non-peak tariff of Malaysian grid into consideration. The simulation results demonstrate that the developed models are able to manage energy consumption and cost reduction efficiently. By using the proposed FLC, the cost of energy is reduced by 21.75 %, 30.77 %, and 41.96 % for the HVAC, EWH, and dimmable lamps, respectively. In sum, the FLC shows good performance to reduce the cost and power consumption toward efficient HEMS.
