Effective System

Essence of process of water-supply of apartment dwelling house is considered. The existent state over of automation of the pumping stations is brought. The task of development of the effective system of automatic control is put by them. Possibility of decision of task is shown by the use in the system of frequency transformer that feeds the electrodrives of pumps, and also due to perfection of algorithms of the pumps rotation frequency adjusting and logical management of their switching a sequence. The practical value of the use of the system is to increase dynamic.

Water supply pumping stations are among the main energy-consuming elements in the water supply system. The energy optimization of a pumping station can significantly affect the energy consumption of a water utility. This article deals with the energy optimization of water pumping stations. The work assumes several variants of optimization of water supply pumping stations through changes in the water supply system, pressure changes in the pumping station, and modification of the number of pumps. After analyzing the network, conducting field tests, and creating a model of the water supply network, the network was calibrated in order to reproduce the existing water network as accurately as possible. Then, a variant analysis was performed, and the best optimization method for the pumping station was selected. In two variants, there was a decrease in electricity consumption; in three there, was an increase; in one, there was no change. By connecting the DMA zones and modifying the pressure in the pumping station, the energy consumption of the pumping stations was reduced. On this basis, it was found that it is possible to optimize the water pumping station by modifying the pumping station and work related to the network layout.

Solar hot water supply systems can provide a significant part of the thermal energy needed in the residential sector. The use of solar hot water supply systems can reduce the consumption of traditional energy sources and, consequently, reduce greenhouse gas emissions. The aim of this article is to assess the operation of the solar heating system operation to provide the needs of the hot water supply system of a residential building with thermal energy. The efficiency of a flat solar collector operating in a single-circuit thermosyphon system of solar heating of a residential building in Lviv has been established. The solar fraction of the hot water supply system of a residential building is determined depending on the volume of hot water consumed, in particular 50, 60, 70, 80, 90, 100 l/day. It is established that the lower the need for hot water, the greater the solar fraction of the solar hot water supply system. Thus, the average annual solar fraction of the solar hot water supply system with a daily consumption of 50 l/day is 0.77, and with a daily consumption of 100 l/day the solar fraction is 0.39. The average value of the solar fraction for the solar hot water supply systems of the studied house is 0.55.

Pumped Storage

In this study, two different energy sources that are connected to a pumped storage water supply system are analyzed: a water and a wind turbine. A water turbine can be integrated in a water supply system in high-pressure locations. Recently, new sources of energy production are being researched and applied due to the increase in the price of conventional energy sources and concerns regarding the damage to the environment caused by their pollutants. On the other hand, water supply systems have equipment that consumes a great deal of energy, such as water and wastewater pumping stations and treatment plants. Energy efficiency that is based on multi-criterion optimization of pump-storage/hydro/wind power management methodology has been developed to analyze the economic viability of a pumping drinking water system that may or may not be connected to a wind turbine or a small hydro whenever excess available head is present.
