A facility based on a photovoltaic and thermal hybrid solar field with seasonal storage tank coupled to water-to-water heat pump is presented in this paper as an adequate energy supply system for building of social homes Zaragoza (Spain), currently under construction. Two types complementary software have been used the complete design, sizing, simulation system. DesignBuilder was determine hour...

In this paper, dynamic simulations of the seasonal coefficient performance (SCOP) Air-Source Heat Pumps will be presented by considering three different heat pump systems coupled with same building located in Italian municipalities: S. Benedetto del Tronto (42°58′ North, 13°53′ East), Milan (45°28′ 9°10′ and Livigno (46°28′ 10°8′ East). Dynamic were conducted employing software package TRNSYS r...

Abstract The building architecture significantly affects the energy consumption of buildings. In this paper, we study effect using U-shape exterior walls on consumption. main target is to evaluate impact parameter heating and cooling loads for a small model in Tetouan, Morocco (an administrative divided into 2 zones, effective area 27 m ). context, parametric was carried out by TRNSYS software ...

Abstract In the residential sector, biomass appliances are widely used for space heating and often combined with other systems. This work aims at comparing final primary energy consumption of different configurations, including a conventional ducted pellet stove wood log using air as heat transfer fluid. A dynamic analysis interaction between stoves systems, such gas boilers radiators, is carri...

In the present research, performance validation of a Heating, Ventilation, and Air Conditioning (HVAC) system operating in a library building was conducted. The operating HVAC system was studied in terms of the provided indoor air conditions and energy consumption level. The fieldwork measurements showed that the HVAC system is not capable of providing the desired indoor air conditions based on...

Heating, ventilation, and air conditioning (HVAC) systems are the second largest energy consumers on cruise ships after propulsion system. As a kind of HVAC system, active chilled beam (ACB) have been widely used for cabin service due to their performance efficiency good thermal comfort. However, conventional control strategies ships’ ACB not intelligent enough cannot balance consumption comfor...

Investigating indoor humidity is important because abnormal moisture levels can damage building structures and result in poor air quality. Outdoor humidity, ventilation rate, internal load are the three dominant factors affecting humidity. State-of-the-art methods, particularly full-scale field studies for determining these be both time consuming labor intensive. This study proposes a radically...

The heating, ventilation, and air conditioning (HVAC) system serving the test room of SENS i-Lab Department Architecture Industrial Design University Campania Luigi Vanvitelli (Aversa, south Italy) has been experimentally investigated through a series tests performed during both summer winter under normal faulty scenarios. In particular, five distinct typical faults have artificially implemente...

The Clean Energy for all Europeans Package pushes the diffusion of renewable energy communities, introducing their definition in European legislative framework. Following this interest, paper analyses and environmental performance a community composed two office buildings located Naples (Italy). Each building has rooftop photovoltaic plant one presents an electric vehicle. heating cooling deman...
