Adsorption refrigeration systems can be built with one, two or more adsorbers. The most common devices are built of two adsorbers. This fact makes the achieved cooling capacity is variable over time, and in some periods ...

Land consolidation works carried out in Poland are mainly aimed at the improvement of spatial structure of plots in agricultural holdings. However, modern trends indicate the necessity of compliance with sustainable rural ...

Adsorption refrigeration systems are characterized by a lower coefficient of performance than the compressor type device or even absorption, but can utilize waste heat at lower temperature. The aim of the study was to ...

The effect of standard means of thermal upgrading of buildings on energy performance indices is studied in the paper. The following was considered: improving thermal performance of the envelope (walls, roof, floors over ...

In the paper a special heat storage unit for building applications is presented. It has a form of a ceiling panel that is made of PCM-gypsum mortar composite and it contains internal channels for air flow, since it is ...

Adsorption refrigeration systems, as opposed to absorption type operate in a cyclic manner. The result is that at the beginning of each process must be fed into the adsorber state in which they will adsorb or desorb a ...

Impregnation of textiles (fabrics) by phase change materials (PCMs) changes their thermal properties. High thermal capacity of PCMs, due to large enthalpy of phase change (latent heat), increases the potential of these ...

The development of the agricultural road network is a complex activity based on a broad range of criteria necessary to be taken into account during analyses and desk studies. The analyses and design solutions cannot be ...

One of main issues concerning server room operation is appropriate cooling of electronic modules to prevent excessive heat generation resulting in their damage. Since high cooling powers are required, precision air ...

The article concerns the properties of bitumens and modified binders manufactured in Poland and used in Central and Eastern Europe for road paving. The aim of the article is to evaluate the properties of bituminous binders ...
