Ключові біомаса, сушка, Abstract. All types of biomass (straw, stalks of corn, sunflower, wood shavings, energy willow, sorghum, miscantus) are colloidal capillary-porous bodies, drying of which is carried out in a high-temperature drying agent and involves the pas-sage of transfer processes due to diffusion, filtration and phase transformations. A mathematical model and a numerical method for calculating the dynamics of heat and mass transfer, phase transformations and shrinkage during the drying of colloidal capillary-porous cylindrical bodies under conditions of uniform cooling by a coolant are developed. The mathematical model was built on the basis of the differential equation of substance transfer (energy, mass, momentum) in de-formable systems. It includes the equations diffusion-filtration transfer of energy for the system as a whole, and the mass transfer of the liquid, vapour and air phases in the pores of the body. Formulas are presented for finding the diffusion coefficients in the liquid and gas phases, for the evaporation rate on the surfaces and in the pores of the particles. Experi-mental studies of the kinetics of dehydration of energy willow particles in the air flow were carried out to verify the mathematical model. Comparison of the results of numerical and physical experiments testify to the adequacy of the mathematical model and the effectiveness of the method for its implementation. On their basis, it is possible to conduct a study of the dynamics of heat and mass transfer during drying of particles of various types of shredded biomass; determine the time to achieve an equilibrium moisture content depending on the properties of the material and the drying agent. It has been established that the small sizes of biomass particles and high heat transfer coefficients at high temperature drying cause their intensive dehydration, and when the material reaches an equilibrium moisture content, the temperature at the outer boundaries of the particles does not reach the temperature of the drying agent. On the basis of these data it is possible to select the process parameters that are optimal from the point of view of energy and quality preservation of the dried product.

. A topical issue at the time, when the cost of traditional energy sources is growing, is using alternative or non-traditional energy sources, such as solar, wind, geothermal, hydropower, bioenergy etc. The most powerful source of energy for humanity is the Sun. The annual amount of solar energy is almost 15 000 times higher than the needs of the population of our planet, but only a small part of it is used for economic needs. The climate of Ukraine gives a potential opportunity of wide use of solar energy. Intervention in the global processes of nature is not possible without changes in every day life in society. In particular, the improvement of the premises, in which people live is necessary, namely their building structures, foundations and materials for the manufacture of such structures. The article deals with the issue of solar fences, such as solar wall, solar window and solar roof. In the article is described the data of changes in the temperature of the heat carrier of the solar wall, the amount of specific instantaneous thermal power in time. It was investigated that at the solar energy intensity of 900 W/m 2 the temperature at the outlet of the solar wall was 40 °C and gradually increased with the stabilization of the system. Whereas, solar fences with a solar roof on intensity of a heat flux І в = 300 W/m 2 there is little variation of efficiency from 0,73 to 0,47 at change of angles of falling from 30° to 90°. The paper analyzes the efficiency of solar fencing with a solar window in the southern orientation of it. It is established that the proposed models of solar fences are quite effective and can be used in solar heat supply systems.

Ukraine is a fruitive land, where we grow a large number of different vegetables, fruits and other crops. To increase the shelf life, the products are processed in different ways, one of which is drying. The development of new technologies for the preservation of fruits, berries, vegetables and medicinal herbs is necessary to reduce costs and obtain products of better quality and nutritional value. In this article, the development of a laboratory stand for the study of drying processes is considered. Various tests of this "individual" stand were conducted on aerodynamic and temperature indices. The great advantage of this laboratory stand is the ability to adjust the amount of air passing through this booth and the amount of heat. The disadvantage of this booth is a calorifer installation that has too much power. During the tests, a modernization of the plant was performed to improve the output parameters for improved convection drying. Convection drying of plums and other fruits was carried out, and comparison of convective drying of plums in comparison with natural drying. Taking into account the previous one, it should be noted that now two main methods of drying are known - natural and artificial, convective (drying with heated air), which is more common. Natural drying is cheap and traditional, but its application depends on the weather conditions and requires large production space and time to receive the finished product. In addition, it is necessary to protect the fruits and berries from insects, small animals and from contact with sources of dirt. With convective drying, you can control these adverse factors and increase the average drying speed, but operating costs increase. In the future, at this laboratory stand, laboratory studies can be carried out to compare the effects of different amounts of "flow" of a drying agent at a constant temperature on the speed of drying of products and taste. It should also be noted that this stand on the study of convective drying can be used to study the processes of drying vegetables, fruits, berries, mushrooms and other plant material in the educational process, as well as for research

. Analysis of the efficiency of central heat supply systems in Ukraine shows that in modern economic conditions, the trend of heat supply systems can develop in the following areas: the use of reduced parameters of the temperature of heat carrier, regulation and automation equipment, the use of condensation flows with deep cooling of combustion products of bio-fuel boilers, the use of vapor compression and absorption heat pumps, use of secondary energy resources of industrial enterprises, cogeneration plants, increased thermal performance of buildings. It is known that the ideal heat energy technology enterprise should use electricity, which is produced on its own secondary thermal resources. Therefore, it is necessary to replace equipment that uses expensive forms of energy with alternative ones. These technologies include chillers and heat pumps that use absorption processes. Heat pumps have a great advantage due to the insignificant cost of energy resources. The need for their use was absent earlier, since heating could be carried out using alternative technologies that were more accepted, and there was no economic necessity in utilizing low-potential heat fluxes. At present, the situation has changed and there is a need to get acquainted with the above-mentioned installations, the potential of which in industry is only starting to use. The absorption reverse cycle, known for several decades, make it possible to replace more expensive and difficult-to-operate compression machines, which cause great harm to the environment. They uses heat energy to compensate the violation of the direction of natural heat transfer. As it is shown on the basis of the analysis of operation parameters of boilers, modernization using these measures can significantly improve the economic and technical characteristics of heat-generating equipment. In the work, two schemes of using the absorption heat pumps for deep cooling of combustion products are proposed. The operation conditions of them are shown. The economy of fuel is very significant - 25...40 %.

A supervising algorithm based on the maintenance of the desired discomfort index (which is the intersection of two indexes: museum peaces and human body) via a fuzzy-controller dealing with museum premises’ microclimate control systems using mechatronic tools. To assess the impact of the environment on the museum peaces and on a person being in the museum premises, it is necessary to determine not only the quantitative value of the microclimate’s individual parameters, but also the result of their overall impact on the human body and museum peaces located in this area. The existing methods of integrated microclimate control by means of mechatronic systems are studied with regard to control methods. The value of such a complex index of discomfort is divided into ranges depending on the average sensation of the comfort in the museum room applicable both for the person (human flow) and museum peaces. The fundamentals of the fuzzy sets theory (Zadeh-Saati) are examined. The synthesis of fuzzy logic controller is carried out. The rules database based on the discomfort index’s calculated values is developed. An intelligent system for the automatic maintenance of comfortable microclimatic conditions in the museum premises is designed. The rule base for the fuzzy-controller is constructed on basis of discomfort complex index’s calculated values for all possible options of dry and humid thermometers’ temperature values. The control effect of the mechatronic microclimate control system of specific museum premises is produced after processing of the aggregated information coming simultaneously from two sensors, thus reducing the number of unnecessary inclusions at low oscillations of each specific parameter. At the same time, special sensors detect the number of people located in the museum premises at the given time and they adjust the operation of the computer-controlled microclimate devices designed for museum premises. Subsequent to the results of simulation, it is possible to note the compliance of the received mechatronic control system with the requirements as for obtaining the desired level of the discomfort complex index in museum premises, the minimum number of executive mechanism’s inclusions (for the currently available one at a given time and for the number of visitors to the museum premises), the lack of overregulation and the energy savings.

The main problem of closed rooms is air pollution with chemical compounds, dust, anthropotoxins and pathogens. Solving this problem with the help of technical and engineering technologies is not always effective, since it requires a lot of time and significant capital investments. The technology of phytodesign by phytoncidal plants is proposed. The purpose of the work is to optimize the air environment by an example of the winter garden in Kiev National University of Construction and Architecture using phytodesign by phytoncidal plants. Objectives of the work: to examine the assortment of plants in the winter garden; to assess whether the number of plants is sufficient for sanitation of the air environment of the premises with an area of 930 m2; analyze the shortcomings of the range of phytoncidal plants; to develop proposals for the phytodesign of a winter garden to improve the quality of the air environment. It was found that the existing number of phytoncidal plants (18 pieces) for effective sanitation of the air in the investigated room is insufficient. Their decorative effect is reduced due to some disadvantages of care. It’s one of the reasons for a decrease in the growth of vegetative mass and the production of phytoncides. For effective air sanitation of the area of the investigated room, 310 specimens of large-sized phytoncidal plants are required. To expand the assortment, the following phytoncidal species are offered: Aglaonema, Anthúrium Aspidistra elatior, Begonia Chlorophytum, Dracena marginata, Ficus benjamina Wiandi, Hedera, Kalanchoe, Nolina, Philodendron, Spatifillum, Scindapsus, Sansevieria, Eucevieriaceae, plants of the families Euphorbiaceae, Orchidáceae, Bromeliaceae. Green phytoncidal zones can also be expanded by introducing "green" structures.

Solving this problem with the help of technical and engineering technologies is not always effective, since it requires a lot of time and significant capital investments. The technology of phytodesign by phytoncidal plants is proposed. The purpose of the work is to optimize the air environment by an example of the winter garden in Kiev National University of Construction and Architecture using phytodesign by phytoncidal plants. Objectives of the work: to examine the assortment of plants in the winter garden; to assess whether the number of plants is sufficient for sanitation of the air environment of the premises with an area of 930 m2; analyze the shortcomings of the range of phytoncidal plants; to develop proposals for the phytodesign of a winter garden to improve the quality of the air environment. It was found that the existing number of phytoncidal plants (18 pieces) for effective sanitation of the air in the investigated room is insufficient. Their decorative effect is reduced due to some disadvantages of care. It’s one of the reasons for a decrease in the growth of vegetative mass and the production of phytoncides. For effective air sanitation of the area of the investigated room, 310 specimens of large-sized phytoncidal plants are required. To expand the assortment, the following phytoncidal species are offered: Aglaonema, Anthúrium Aspidistra elatior, Begonia Chlorophytum, Dracena marginata, Ficus benjamina Wiandi, Hedera, Kalanchoe, Nolina, Philodendron, Spatifillum, Scindapsus, Sansevieria, Eucevieriaceae, plants of the families Euphorbiaceae, Orchidáceae, Bromeliaceae. Green phytoncidal zones can also be expanded by introducing \"green\" structures.","PeriodicalId":23499,"journal":{"name":"Ventilation, Illumination and Heat Gas Supply","volume":"34 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80143009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
