Analysis of a HVAC zoning control system with an air-to-water heat pump and a ducted fan coil unit in residential buildings
Fernández-Hernández, Francisco Ángel; Atienza Márquez, Antonio; Peña Suárez, José Miguel; Bandera Cantalejo, Juan Antonio; González Muriano, María del Carmen (Elsevier, 2022-07-08)This paper presents an analysis of a thermal zoning system integrated in a Heating, Ventilation and Air- Conditioning (HVAC) system based on an air-to-water heat pump with a ducted fan coil. Zoned systems are based on ... -
Domestic hot water production system in a hospital: Energy audit and evaluation of measures to boost the solar contribution
Atienza Márquez, Antonio; Domínguez-Muñoz, Fernando; Fernández-Hernández, Francisco Ángel; Cejudo-López, José Manuel (Elsevier, 2022-12-15)Hospitals consume large quantities of energy to produce hot water and offset the distribution and recirculation thermal losses. This paper analyses a solar thermal system combined with gas boilers for domestic hot water ... -
Impact of zoning heating and air conditioning control systems in users comfort and energy efficiency in residential buildings
Fernández-Hernández, Francisco Ángel; Peña Suárez, José Miguel; Bandera Cantalejo, Juan Antonio; González Muriano, María del Carmen (Elsevier, 2022-07-05)Nowadays, in the residential sector, a widely used heating, ventilation and air conditioning system is the ducted direct expansion inverter system based on the on/off control of a single zone, which cannot guarantee the ... -
Optical characterization of a funnel solar cooker with azimuthal sun tracking through ray-tracing simulation
Carrillo-Andrés, Antonio; Apaolaza-Pagoaga, Xabier; Rodrigues-Ruivo, Celestino; Rodríguez-García, Eduardo Amador; Fernández-Hernández, Francisco Ángel (Elsevier, 2022-01-20)Funnel type solar cookers are simple and effective. Most of them rely on a multifaceted reflector to concentrate solar radiation on a cooking pot that is placed inside a transparent enclosure to create a greenhouse effect. ... -
The effect of partial loads on the performance of a funnel solar cooker
Apaolaza-Pagoaga, Xabier; Carrillo-Andrés, Antonio; Rodrigues Ruivo, Celestino; Fernández-Hernández, Francisco Ángel (Elsevier, 2022-11-20)Several solar cooker designs have been proposed over the last decades. The funnel cooker is a well-known model, representative of the category of panel-type solar cookers. From the empirical experience of real practice, ...
