Thermal conductivity detector for use in gas dynamic express-analyzers and high-speed chromatography systems is being developed by chemistry department in cooperation with other Samara University departments. This article is devoted to investigating the effect of temperature on detector sensitivity. Silicon underlying with resistive chromium layer was used as a sensitive element of the detector. The temperature dependence of the sensitive element resistance was defined for different chromium film thicknesses. The film thickness which provides the highest sensitivity of the detector was found. Also optimal output channels configuration in the gas chromatograph detector was determined. It provides uniform temperature fields distribution at constant gas-flow rate. 

Abstract. The problems of high energy loss exists in many industries and in many technological processes. The problem of not effective use of the energy potential of the refrigerants is the main problem, because the refrigerant loses its potential and the potential energy at the regasification upon receipt of the liquefied natural gas. Solution of this problem is using low-grade heat of the refrigerant. This investigation describes the creation of a design procedure of the installation of the cycle that uses low-grade heat of the refrigerant. The cycle that uses low-grade heat of the refrigerant has been described and calculation method has been developed.

“…Throttle cryogenic systems are most easily amenable to miniaturization, but have the lowest efficiency in comparison with other types of closed systems due to the imperfections of the throttling process and small isothermal efficiency. However, the effectiveness of throttle microcryogenic systems can be significantly increased by the coolants' thermal properties improvement [5].…”

Abstract. Efficiency is one of the most important parameters that apply to the cooling system. This paper describes a development of universal methodology to evaluate the effectiveness of cryogenic cooling systems. The problem of the lack of a universal method of comparison of cryogenic cooling systems was solved. This was achieved by creating a universal method of exergy analysis. In addition, as an example were examined three of the cooling system, which applies the universal exergy analysis. Basic universal parameters that characterize cooling system level of sophistication were defined, as well as main calculated. The result of this study is a new universal method of exergy analysis, which can be used to select a cryogenic cooling system.
