Abstract Hollow polymer particles are widely used in various industries as coatings and thermal insulation materials. The encapsulation capabilities of functional molecules and/or nanomaterials also provide access to applications such drug delivery, heat storage, catalysis, well self‐healing In this study, we successfully fabricated hollow from poly(vinyl cinnamate) (PVC) using LED light ( λ = ...

In Slovakia, 35% of buildings are older than 50 years but most newer buildings built before 1990 have greater energy consumption. Some other countries also have similar problems. The growing importance of energy saving in buildings can be, in the case of new and old residential buildings (RB), achieved by lowering thermal energy consumption most often by application of polystyrene insulation on...

Plumbing system planning is an important part of a building to meet clean water needs. This study aims plan plumbing for in the ITP main building. Meeting needs planned use sources from shallow wells that are pumped into roof tank (roof tank) and flowed gravitationally pump two. The results calculation average requirements office buildings 53 liters / day. capacity needed accommodate 2,100 lite...

This paper presents experimental studies on thermal stratification in chilled-water storage systems. A fibreglass storage tank in static and dynamic modes of operation is used. The parameters varied are aspect ratio, flow rates, initial temperature difference and thickness of insulation. Emphasis is given to the effects of mixing at the inlet, leading to the definition of the mixing coefficient...

In combination with seasonal thermal energy storage (STES), solar offers a vast potential for decarbonizing the residential heat supply. this work, parametric optimization is conducted to assess of reducing costs water-based STES through use alternative insulation materials and integration an underground outside building. The investigated configurations include: hot-water tank, collector instal...

Abstract In this paper, studies concerning the changes brought by gamma radiation on some PVC plates were made. The respective samples exposed to irradiation, at room temperature and different doses, such as (10, 20, 40, 80) kGy. in irradiated plates’ properties studied UV-Vis, electrical measurements, SEM analysis non-irradiated samples. results show that irradiation affects of plates. This de...
