APPLICATION OF THE THERMOELECTRIC HEAT PUMPS FOR THE DISTRICT HEATING SYSTEMS
Energy Technologies & Resource Saving, 2020 The article presents a preliminary analysis of the possibility of applying thermoelectric heat pumps (THP) in low-temperature district heating systems (in the 4–5 generation DH systems). The advantages of THP are the high reliability, the lack of moving parts and freons in their composition, the compactness, the independence of the scale factor. Unlike

Advanced Engineering Materials, EarlyView.New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing
Advanced Engineering Materials, EarlyView.This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

The heat load in district heating systems
, 1984 This thesis considers the composition of the daily heat load in six Swedish district heating systems supplying heat for space heating and hot water supply. The analysis was performed by bringing together a heat load model and series of daily heat load observations covering periods ranging from five to eleven years.

Performance Analysis of Abradable Coating Systems for Aircraft Gas Turbines
Advanced Engineering Materials, EarlyView.Three CoNiCrAlY/YSZ/MgAl2O4 abradable liner configurations on a nickel‐superalloy are evaluated by thermal‐gradient cycling and incursion tests. Laser ablation of the bondcoat and/or Y2O3‐stabilized ZrO2 (YSZ) intermediate layer increases mechanical interlocking and bonding for thick topcoats.
