Analysis and optimization of different two-stage transcritical carbon dioxide cycles for heating applications

Pitarch Mocholí, Miguel; Navarro-Peris, Emilio; Gonzálvez Maciá, José; Corberán Salvador, José Miguel (Elsevier, 2016-10)

[EN] Increased interest in the environmental impact of refrigeration technology is leading toward design solutions aimed at improving the energy efficiency and use of eco-friendly refrigerants with low GWP. The aim of this ...
CO2 refrigeration system heat recovery and thermal storage modelling for space heating provision in supermarkets: An integrated approach

Maouris, Georgios; Sarabia Escrivà, Emilio José; Acha, S.; Shah, N.; Markides, C. (Elsevier, 2020-04-15)

[EN] The large amount of recoverable heat from CO2 refrigeration systems has led UK food retailers to examine the prospect of using refrigeration integrated heating and cooling systems to provide both the space heating and ...
Evaluation of different heat pump systems for sanitary hot water production using natural refrigerants

Pitarch, Miguel; Navarro-Peris, Emilio; Gonzálvez-Maciá, José; Corberán, José M. (Elsevier, 2017)

[EN] Heat pumps that work with a high degree of subcooling in subcritical systems have shown a significant margin of improvement when working with sanitary hot water applications. Recently, two different approaches ...
Evaluation of optimal subcooling in subcritical heat pump systems

Pitarch, Miquel; Hervas-Blasco, Estefanía; Navarro-Peris, Emilio; Gonzálvez-Maciá, José; Corberán, José M. (Elsevier, 2017)

[EN] The performance of a transcritical cycle is highly dependent on the rejection pressure. The optimal rejection pressure depends mainly on the inlet and outlet temperatures at the heat sink (secondary fluid). For the ...
Experimental study of a heat pump with high subcooling in the condenser for sanitary hot water production

Pitarch, Miguel; Navarro-Peris, Emilio; Gonzálvez-Maciá, José; Corberán, José M. (Taylor & Francis, 2018)

[EN] The use of heat pumps in order to produce sanitary hot water have been demonstrated as a very efficient alternative to traditional boilers. Nevertheless, the high water temperature lift (usually from 10 degrees C to ...
Experimental study of a subcritical heat pump booster for sanitary hot water production using a subcooler in order to enhance the efficiency of the system with a natural refrigerant (R290)

Pitarch, M.; Navarro-Peris, Emilio; Gonzálvez-Maciá, José; Corberán, José M. (Elsevier, 2017)

[EN] This paper presents the experimental results obtained from a new heat pump prototype for sanitary hot water production, in the application of heat recovery from water sources like sewage water or condensation loops ...
High capacity heat pump development for sanitary hot water production

Pitarch i Mocholí, Miquel (Universitat Politècnica de València, 2017-05-29)

Heat pumps have been identified as an efficient alternative to traditional boilers for the production of sanitary hot water (SHW). The high water temperature lift (usually from 10ºC to 60ºC) involved in this application ...
PROYECTO PARA LA SUSTITUCIÓN DE UN SISTEMA DE REFRIGERACIÓN CON AMONIACO INUNDADO DE LOS AÑOS 70, POR UN NUEVO SISTEMA DE REFRIGERACIÓN INDIRECTO CON AMONIACO Y GLICOL CON UNA POTENCIA FRIGORÍFICA 350 KW EN OLIVA

González Bellver, Joan Batiste (Universitat Politècnica de València, 2023-11-06)

[ES] El objetivo de este proyecto es la sustitución del sistema de refrigeración de las instalaciones de una industria donde su actividad era la conservación de productos agrícolas de la comarca de la Safor. Tras 50 años ...
