The energy saving is becoming an important topic also in the food industry. For this reason, it is important to use multi-energy systems to produce hot water for processes and space heating. The application considered in this paper, which concerns a chocolate factory, focuses on the hot water production through a multi-source storage tank. The water inside the tank is heated by four solar panel...

On one hand, the use of solar energy for heating and electricity production should increase in the future to reduce greenhouse emissions. On the other hand, the use of water to water heat pumps allows the production of heat effectively in many applications. In this context, it is appropriate to study the concept of a reversible HP/ORC unit. This innovative system includes a water to water heat ...

Solar heating is one of the important utilities of solar energy both in domestic and industrial sectors. Evacuated tube heaters are a commonly used technology for domestic water heating. However, increasing cost of copper and nickel has resulted in huge initial cost for these types of heaters. Utilizing solar energy more economically for domestic use requires new concept which has low initial a...

This involves having production units distribute to the consuming units through a single vertical and central distribution network. Each fl oor is served by an indirect connected substation (Figure 3). Enhancing comfort1 and reducing energy demand2 is possible when fl oorto-fl oor (rather than building-to-building) consumption is moderate (cooling) or low (heating) temperature radiant-based sur...

Passive and active solar heating systems have drawn much attention and are widely used in residence buildings in the Qinghai-Tibetan plateau due to its high radiation intensity. In fact, there is still lack of quantitative evaluation of the passive and active heating effect, especially for residential building in the Qinghai-Tibetan plateau areas. In this study, three kinds of heating strategie...

Aim of study: In this study, the effects use solar water heating system forest villagers in Gumushane were investigated. 
 Material and methods: For purpose, random selected by 70 village households examined results analyzed One Sample T-Test. Within scope research, face-to-face surveys conducted with families who determined information provided Department Forest-Village Relations. The cho...
