The purpose of this paper is to represent inner air temperature calculation algorithm provided that interior space is formed by several building envelopes which transmit thermal losses. The chosen external wall includes an area with damaged structural layers. We examine one-dimensional thermal transfer between hot (inner) and cold (outside) space in steady-state conditions. The derived equation allows calculating the estimated inner temperature of the air taking into consideration the various combination of building envelopes on condition that one of them is damaged.

The article describes the construction of dynamic subsystem logical and dynamic model for batch sterilizer with counter-pressure needed for the construction of programmer.To describe the dynamics of counter-pressure autoclave is used mathematical method that takes into account the sequence of the autoclave.Modeling scheme for areas of heating and shutter, and cooling area are programmed in MatLab with the the heat balance equation. There are circuit modeling temperature changes in banks in areas of heating and shutter speed and cooling section.Abstract: The technologies of thermal treatment in vacuum are widely used in various fields of production, in particular in the food industry, but their application at farms, hotels or a for domestic purposes is limited because of the big sizes, high cost of processing equipment and complexity of its management at realization of foodstuff processing. Products, made with use of vacuum technologies, keep much more useful substances because they aren't exposed to high-temperature processing and oxidation while preparation. Development and production of the small-sized equipment for realization of heat treatment processes of foodstuff in vacuum would create technical and economic conditions for implementation of temperature processing processes of foodstuff at farms, hotels and even at home that would promote creation of new food, development of new recipes and, in general, development of the new direction in cookery. So the article describes the problem of equipment construction for the process of thermal processing of food in vacuum such as cooking jam, concentration of juices and dairy products, distillation, drying, pickling, and the possibility of building inexpensive compact vacuum unit for the implementation

The parameters of microclimate in computer classrooms during a warm season were under investigation.
