Reduce Energy Consumption

In geographical areas with cold climates, large, massively constructed industrial and warehouse buildings and logistics complexes are large consumers of energy resources. The great height and large contained volumes of the premises, the presence of a significant number of doors, and building configurations that include many transport corridors all require the use of air-thermal curtains to increase the energy efficiency of the buildings’ heating, ventilating, and air-conditioning (HVAC) systems, which commonly produce several thousand kilowatts of thermal power. Optimization of air curtains can improve the microclimates of the premises, achieve savings in the initial construction costs, and also reduce energy consumption during operation by 10–20%.

In the past decade, Chinese urban areas have seen rapid development, and rural areas are becoming the next construction hotspot. The development of rural buildings in China has lagged behind urban development, and there is a lack of energy-efficient rural buildings. Rural houses in severe cold regions have the characteristics of large energy exchange, a long heating cycle, and low construction costs. Energy consumption is a crucial issue for rural houses in severe cold regions. How to balance the energy efficiency and building cost become a crucial problem. To solve this problem, we investigate the energy consumption of rural housing in cold regions, using Longquan Village in Heilongjiang Province, northeast China, as a case study. A low-energy design framework is established that considers the spatial layout, building type, enclosure system, and heating system. With the support of project funds, a demonstration house is constructed, and the energy savings performance of the building is investigated during the heating period. The results indicate that the energy savings rate of the demonstration house is 66%. The demonstration building enables local residents to learn construction methods for low-energy houses and promotes energy efficiency.

The energy efficiency of household refrigerating appliances was measured according to EN TSO15502. A Liebherr TKP 1650 built-in Domestic refrigerator is used to determine the influence of the capillary pipe geometry. The temperatures at the injection site of the refrigerant, the inlet and outlet of the evaporator receiver were measured. The obtained results show that there is no universal optimal geometry of the capillary pipe. There is no element of the refrigeration cycle whose change has no effect on the refrigerant flow rate passing through the capillary pipe. A change in the geometry of capillary pipe affects all other components of the refrigeration cycle and can greatly improve or impair the efficiency of the refrigerator. The potential for switching from one to two different geometries of the capillary pipe is approximately 8% improvement in energy consumption. Possible implementation should take into account the potential savings - 8% and the life cycle of the particular appliance (- 15 years). For the particular measured device, the consumption per year is about 75kWh, which should take into account that the device itself has a low volume and low energy consumption.

Summary. One of the main factors in ensuring the energy security of a manufacturing enterprise is to reduce the energy intensity of manufactured products. The world's leading countries have significantly reduced energy consumption in recent years. And domestic enterprises, today, remain one of the least energy efficient in the world. A significant part of energy resources is spent due to depreciation of fixed assets and obsolete equipment. Today, the economical and efficient use of energy is one of the main issues that need to be solved. After all, the lower the level of use of energy resources, the more efficient the production, and the more competitive the products on the world market. Therefore, in order to assess the level of energy efficiency, we have systematized economic indicators that characterize the use of energy resources in the enterprise. Based on them, the structure of an integrated indicator of the level of energy efficiency of a machine-building enterprise is proposed. The structure includes four groups, which in turn include from two to four indicators. The first group of indicators characterizes the energy efficiency of the enterprise, the second - innovative activities in the direction of energy efficiency, the third - investment activities, the fourth - the socio-environmental consequences of the introduction of resource-saving technologies. An algorithm for determining the level of energy efficiency of machine-building enterprises based on the principles of systems analysis, which is based on integrated assessment, is also proposed. The implementation of the proposed algorithm will determine the level of energy efficiency of the enterprise and identify possible ways to reduce energy consumption. The proposed algorithm was tested at four machine-building enterprises of the Zaporizhia region and the obtained results were substantiated. It is established that the level of energy efficiency of the studied machine-building enterprises is very low. Which indicates the irrational use of energy and, accordingly, the very high energy intensity of the products.

This article discusses the application of the data envelopment analysis in the energy efficiency measure of the industries, which thinks that according to energy consumption intensity industries can be divided into three categories, high, middle and low energy consumption, respectively discussion will have more theoretical significance. Later, this paper chooses constant returns to scale model, respectively measures total factor energy efficiency to three kinds of Inner Mongolia industrial industries, and summarizes the changes and characteristics of energy efficiency in these three kinds of industries. Result shows that, the energy efficiencies among high energy consumption industries are similar and recently they began to decline; the energy efficiencies of middle energy consumption industries are relatively high, but there are some differences between industries; in most low energy consumption industries energy efficiencies are low and the fluctuation is lesser, but several fluctuations are bigger which industries are worth our attention.

In this paper, a review on the LoRa antenna design for IoT application is studied. The expansion of the Internet of Things ( IoT) has led the industry to develop new communication solutions, as current protocols are inadequate in terms of scope and energy efficiency to satisfy IoT requirements. Before studying antenna design, some background LoRa and IoT were discussed at beginning of the paper. LoRaWAN is an open LPWAN standard developed by LoRa Alliance and has main characteristics such as low energy consumption, long-range communication, builtin protection and GPS-free positioning. Besides, a comparison according to the method, resonance frequency, material, size of the antenna and the output is shown in the form of table. In addition, the strength and the weakness of each of the antenna design were discussed before the end of the paper.
