In this paper, the authors aim to support users when modelling scenarios with complex processes entailing thermal loads and infiltrations. The large building analysed is a logistics centre for replenishment distribution of perishable foodstuffs where cold chains must be maintained. centre, 96 loading/unloading docks, handles turnovers different goods. This produces heat inside facility. Due con...

The objective of this study was to modify an existing liquid desiccant and indirect/direct evaporative cooling-assisted 100% outdoor air system (LD-IDECOAS) for humidification operation in winter. energy benefit the desiccant-assisted approach during LD-IDECOAS over conventional method with a steam humidifier evaluated through detailed simulation. enthalpy effectiveness values measured from lab...

The impact of thermal comfort demand on the renovation process was carried out an optimization basis for thermo-modernization exemplary single-family home located in Warsaw. verified TRNSYS simulation program used to generate a set variants building modernization solutions. This afterwards as database optimization. analysis performed includes internal air temperature, indicators (PPD), and annu...

Buildings are accountable for nearly 40% of global greenhouse gas emissions. Their overall efficiency is thus a major pillar to optimize energy consumption and mitigate engendered warming. The current work takes part in this dynamic. Indeed, we developed standalone decision-aid tool based on sensitivity analysis, multiobjective optimization, artificial neural networks design new generation ener...

According to the authors of this paper, mathematical point view allows us see what sometimes cannot be seen from designer’s view. The aim study was estimate influence most important parameters (volume heat storage tanks, daily consumption domestic hot water, optical efficiency, loss coefficient, and total area a solar collector) on thermal power output water (SDHW) system in European climatic c...

Centralized hot water systems are commonly installed in college student dormitories, representing a typical application for such systems. To achieve sustainable and environmentally friendly heating solutions, air-source heat pump have gained attention their high efficiency energy-saving characteristics. By implementing technology, China could make significant progress towards achieving its carb...

This study focuses on the modelling and simulation of an existing active forced circulation solar water heating system in College Science Technology under Royal University Bhutan. The installed prototype consists five flat-panel collectors connected parallel, with a gross surface area 10 m2, 500-litre storage tank built-in heat exchanger to preheat student mess. TRNSYS (Transient System Simulat...

Nowadays, rehabilitation in historic centers can become a challenge due to the restrictions concerning requirements for building envelope. Portugal has conducted studies define maximum U values [W/(m2 K)] single components based on indoor temperature. Despite relative humidity being crucial thermal comfort, current Portuguese scheme energy certification of buildings does not consider it. Additi...

A real case study of an energy system based on a Solar Assisted Heat Pump (SAHP) fed by hybrid photovoltaic-thermal solar panels (PVT) and seasonal storage (SS) is presented in this paper. Exergy exergy cost analyses are proposed as complementary methods for the assessment better understanding efficiency cogeneration configuration. The performance takes advantage heat summer, when resource high...
