Abstract. The method of determining a microclimate comfort level have been developed, taking into account the main parameters influencing the microclimate in residential, public and administration buildings, their mutual influence on the comfort level, and air quality.

Abstract.We have proposed a new construction the pump chamber. We have carried out development of a mathematical model of the pump work chamber. On the basis of mathematical modeling we have proved the efficiency of applied design solutions. Adopted by the us constructive solutions to will improve the performance of the pump chamber by 2.34 times.Economy and Improved utilization of energy resources are among the eight priority areas of the policy of the Russian Federation, approved by Presidential Decree of July 7, 2011 N 899 "On approval of the priority directions of development of science, technology and engineering in the Russian Federation and the list of critical technologies of the Russian Federation" . The main consumers of energy resources are industrial enterprises. The implementation process in many industries require moving large amounts of bulk materials. The share of pneumatic transport accounts for about 30% of all work on the transport of bulk cargo. Pneumatic conveying systems have a number of advantages over traditional means of transport of bulk materials: compactness, high hygiene in indicators, possibility of full automation, the ability to simulation time as the transportation of material to change its status (drying, moisturizing, etc.), easy maintenance [1, 2, 3]. However, the pneumatic transport system have the highest energy consumption per ton of processed material. In some cases, this figure exceeds the energy consumption of traditional modes of transport by 10-15 times. High energy intensity is often associated with errors in the design phase systems, because existing engineering design procedure of pneumatic units does not take into account the specifics of various industries, which leads to lower energy efficiency of pneumatic systems. Therefore, at present it is a very urgent problem of energy efficiency in transport systems, pneumatic transport of bulk materials. In order to enhance the energy efficiency of the pump chamber has been developed mathematical model of two-phase flow and heat transfer (gas-solid). A mathematical model based on the equations of motion, conservation of energy and mass in the production of interpenetrating flows (Euler model) [4,5]. It is assumed that the bulk material has the properties of pseudo-liquid. The system of differential equations is of the form: 1.
