Increase in the repair period of laminate heat exchangers using the thermoelectric Pelletier module

Abstract

The article sets the task of developing a method for increasing the overhaul period during operation of laminate heat exchangers. To solve this problem, the use of a thermoelectric module is proposed. The article presents experimental studies of the nature of heat transfer between two streams in a laboratory setup simulating a process on a plate heat exchanger. The experimentally substantiated dependences of the deposition value on the thermopower voltage indicators are obtained. Based on the obtained dependences, the possibility of developing a program for maintenance and repair of laminate heat exchangers is shown.

Methods of Improving the Safety of Drilling Works

“…To assess the sufficiency of structural units to achieve functions, an additional element is introduced µ ν (0 ≤ µ ν ≤1). For scoring it is recommended to use the scale of qualitative assessments (table 2) [13][14][15]. The proposed modification of the decision matrix method allows obtaining a dependence characterizing the contribution of structural units to the implementation of functions according to the formula:…”
