Moisture inside the footwear can considerably affect the thermal insulation. In this study with a thermal foot model there was simulated three sweat rates (3, 5 and 10 g/h). Five types of footwear with various insulation levels (dry insulation from 0.19 to 0.50 m2 · K/W) were tested. The footwear insulation reduction was calculated for 1.5 hour period. The reduction in insulation was related to...

From the perspective of technical suitability, this paper comparatively analyzed economical thickness and suitable exterior wall thermal insulation material with highest energy saving rate building envelop, attained relationship, curves, model material. The purpose is to provide useful evidences for residential buildings optimization design wall, so that architectural designers could be inspire...

The application of lightning impulses to polymer insulation, including composite insulators, can result in the deposition and retention of significant quantities of charge on the surfaces. This is very evident after withstand impulses near U50. The presence of retained charge means that the polymer test object has a memory of preceding impulses and this compromises the main requirement for dete...

A popular retrofit option is to install an exterior insulation finish system to the walls of existing buildings. This study evaluates the thermal and moisture performance of such a system with a vented wall assembly. In addition to being a case study, this field monitoring was intended to verify computation methods of building envelope performance. The long term monitoring was designed to be no...

Distances from the insulation shell of pipelines duringchannelless laying to utility networks are recommended by regulatory documents, but in real conditions it is not always possible comply with these parameters. Calculations have been made verify that gas pipeline can be laid next supply heating network problematic section installation where restrictions met. The soil temperature on wall case...

Introduction. At present, the overall production of light two- and three-layer wall panels coatings having metal claddings efficient insulation is continuously increasing in Russia. Especially relevant use sandwich panels, since industrial administrative buildings can be quickly erected, thereby significantly reducing their payback period. Regulatory documents regulating processes were mainly d...

The paper aims at studying different strategies for the optimal operation of Breathing Walls during summer. investigation is carried out by performing dynamic simulations on a case study. To this purpose, transient Finite-Difference numerical model Wall components, previously developed in Matlab and validated Authors, coupled with TRNSYS. study consists an office room located Milan, Italy, prov...

Hyperosmolar food causes atherosclerosis. Hyperosmolal food hypothesis encompasses all the factors involved under one heading and, that is, the generation of heat in the body. The involvement of cigarette smoking is obvious. High glycemic index food and diabetes result in high levels of blood glucose, which raises the core body temperature. The ingestion of hyperosmolal salt, glucose, and amino...

Abstract: There exists huge differences in climatic conditions and occupant energy-consuming behavior between Berlin and the “hot summer and cold winter zone of China” (HSCW), which implies that the building energy consumption compositions of two regions are completely different. In this paper, dynamic energy consumption simulation for passive houses with Design Builder software was performed. ...

The oven, in which the diffusion runs were carried out, was built of a vertical glass tube with a Kanthal winding (see Fig. 1). This winding was supplied with some extra terminals; shunting parts of it allowed the temperature to be kept constant (or slightly increasing upwards) over a sufficient length in the oven. The insulation consisted of rockwool, a section of which could be removed tempor...
