A comparison of heating terminal units: Fan-coil versus radiant floor, and the combination of both
Atienza-Márquez, Antonio; Fernández-Hernández, Francisco Ángel
; Domínguez-Muñoz, Fernando; Carrillo-Andrés, Antonio; Cejudo-López, José Manuel (Elsevier, 2017)
Several control strategies are compared for a hydronic heating system that combines two different terminal units, radiant floor and fan-coil, in the same thermal zone. The performance of the combined system is evaluated ... -
An experimental and numerical model of a desiccant façade. A case of study of an office building in different weather conditions
Fernández-Hernández, Francisco Ángel; Jiménez-Navarro, Juan Pablo; Atienza-Márquez, Antonio; Cejudo-López, José Manuel; Carillo-Andrés, Antonio (Elsevier, 2020-10-01)
Meeting thermal comfort in buildings with high latent loads requires the treatment of the air humidity with specific technologies. Desiccant based systems have proved to be effective in removing ventilation latent load in ... -
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 ... -
Cold recovery from LNG-regasification for polygeneration applications
(Elsevier, 2018)Liquefied Natural Gas (LNG) has a high exergetic potential because of its low temperature (around −162 °C), although usually the cold released from LNG regasification is wasted. In this paper, the LNG supply chain and the ... -
Design under uncertainty of solar hot water systems for hospitals
Atienza Márquez, Antonio; Domínguez-Muñoz, Fernando; Fernández-Hernández, Francisco Ángel; Cejudo-López, José Manuel (2022)
Failed designs are often behind underperforming solar hot water systems and excessive fossil fuel consumption in backup units. This paper proposed a reliable and robust method to design a solar thermal system combined with ... -
Detailed and simplified models of a terminal unit that combines an UFAD system with a floor cooling
Atienza-Márquez, Antonio; Fernández-Hernández, Francisco Ángel; Domínguez-Muñoz, Fernando; Cejudo-López, José Manuel (Elsevier, 2018)
This paper analyses the thermal behaviour of an underfloor air distribution system (UFAD) combined with a floor cooling, focusing on the thermal decay (TD). Two new models were implemented: a detailed model based on the ... -
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 ... -
Fluids selection and performance analysis of a polygeneration plant with exergy recovery from LNG-regasification.
(Elsevier, 2019)Liquefied Natural Gas (LNG) is a valuable exergetic source due to its low-temperature (−162 °C). However, LNG is regasified using seawater as heat source and without exergy recovery in most of LNG terminals worldwide. In ... -

Modeling and dynamic simulation of a hybrid liquid desiccant system with non-adiabatic falling-film air-solution contactors for air conditioning applications in buildings
(MDPI, 2021-01-02)This paper presents an experimentally validated, dynamic model of a hybrid liquid desic-cant system. For this purpose, we developed new components for the air-solution contactors, which are of the non-adiabatic falling-film ... -
Modelling and dynamic simulation of a liquid desiccant system coupled to a heat pump for air conditioning.
(2019-08-23)In applications where latent loads or ambient humidity are high, liquid desiccant systems combined with vapor compression systems are a suitable alternative to conventional HVAC systems because they can efficiently control ... -
Optimización del control de un sistema de calefacción conjunto de suelo radiante y ventiloconvectores
Atienza Márquez, Antonio; Cejudo-López, José Manuel; Fernández-Hernández, Francisco Ángel; Domínguez-Muñoz, Fernando (2015-07-03)
Los sistemas de calefacción que utilizan suelos radiantes presentan ventajas frente a los que impulsan aire: mejor distribución espacial de temperatura, mayor rendimiento en la producción y mejor integración. Sin embargo, ... -
Performance analysis of a combined cold and power (CCP) system with exergy recovery from LNG-regasification
(Elsevier, 2019)Liquefied Natural Gas (LNG) is becoming vital in relation to energy transition and fighting climate change. Because of its cryogenic temperature (111 K), LNG is an exergy “mine” that can be exploited in the regasification ... -
Recovery and transport of industrial waste heat for their use in urban district heating and cooling networks using absorption systems
(MDPI, 2020)The use of industrial excess heat in district heating networks is very attractive. The main issue is the transport of the heat from the point of generation to the local distribution network, in a way similar to the structure ... -
Regasification of liquefied natural gas in satellite terminals: Techno-economic potential of cold recovery for boosting the efficiency of refrigerated facilities
(Elsevier, 2021)The regasification of liquefied natural gas releases low-temperature thermal energy, which is usually wasted. Most initiatives to recover this cold mainly focus on large-scale harbour terminals rather than on small-scale ... -
